Description:
FIELD 
       [0001]    This invention relates generally to forums, more particularly, to systems and methods for directed forums. 
       DESCRIPTION OF THE RELATED ART 
       [0002]    A forum can be regarded as essentially a website composed of a number of member-written threads. Each thread entails a discussion or conversation in the form of a series of user-member written posts. These threads remain saved on the forum website for future reading indefinitely or until deletion by a moderator. 
         [0003]    Software packages that implement forum websites are generally well known. These software packages are widely available on the Internet in a variety of programming languages such as HypeterText Preprocess (“PHP”), Perl, Java, and active server pages (“ASP”). The configuration and records of posts can be stored in text files or in a database. 
         [0004]    Although forums are an effective tool to exchange information, they are not without drawbacks and disadvantages. For example, a user trying to obtain information on a particular issue may find it very difficult to locate a definite answer on the issue. Accordingly, there is a need to improve the likelihood of a user to obtain an answer for any issue the user may have.

     DETAILED DESCRIPTION OF EMBODIMENTS 
       [0017]    For simplicity and illustrative purposes, the principles of the present invention are described by referring mainly to exemplary embodiments thereof. However, one of ordinary skill in the art would readily recognize that the same principles are equally applicable to, and can be implemented in, all types of information portals, and that any such variations do not depart from the true spirit and scope of the present invention. Moreover, in the following detailed description, references are made to the accompanying figures, which illustrate specific embodiments. Electrical, mechanical, logical and structural changes may be made to the embodiments without departing from the spirit and scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense and the scope of the present invention is defined by the appended claims and their equivalents. 
         [0018]    Embodiments pertain generally to a directed forum in a service portal. More particularly, a directed forum module can be configured to provide a forum for a user community of the service portal. The directed forum module can also be configured to provide a list of available personnel in a technical assistance (or help) group. More particularly, the directed forum module can generate a graphical user interface (“GUI”) widget (i.e., an on-line widget) such as a list box, dialog box, etc., that contains a listing of the available personnel in the help group that are logged in and available to assist users. Unavailable personnel can be displayed as a separate listing or included with the listing of available personnel but with a busy icon. The help group can comprise of technical support personnel, technical experts, and qualified users. A technical support personnel can be a user employed by the administrators of the service portal to provide technical support for the user community. A technical expert is a user that has credentials certified by the user community in a particular field and may or may not be employed by the service portal. A qualified user (“good samaritan”) can be a user that the user community that has some technical skill and would like to be helpful. The status of a user can be maintained in a profile associated with the user. 
         [0019]    The directed forum can monitor the log-ins of users into the service portal. If the profile of a logged-in user indicates that the user is part of the help group, the direct forum module places the user in the on-line widget. Alternatively, the directed forum module can periodically monitor a logged-in user list maintained by the service portal. The directed forum module can then search the logged-in user list for the anyone in the help group to place on the on-line widget. 
         [0020]    The directed forum can also be configured to direct questions from the users to the appropriate person(s) in the on-line help group. More specifically, a user can issue a question in the directed forum. The directed forum can be configured to parse the question for key words (e.g., Linux, Red Hat, configuration file, etc.). The directed forum can then use the key words to search the user profiles of the available personnel in the on-line help group for the same key words. The directed forum can forward an electronic message to the matching users in the on-line help group based on key words. Accordingly, a user can get an answer to his issue or question in a time efficient manner because the issue has been directed to available person who is likely to have an answer. 
         [0021]      FIG. 1  illustrates an exemplary system  100  in accordance with an embodiment. It should be readily apparent to those of ordinary skill in the art that the system  100  depicted in  FIG. 1  represents a generalized schematic illustration and that other components may be added or existing components may be removed or modified. Moreover, the system  100  may be implemented using software components, hardware components, or combinations thereof. 
         [0022]    As shown in  FIG. 1 , the system  100  includes a service portal  105  coupled to a network  125 . Users  130  can interface with the service portal  105  through the network  125 . The network  125  can be a combination of local area networks, wide area networks, public networks, and private networks or combinations thereof such as the Internet. 
         [0023]    The users  130  can be interface with the service portal  105  using computing platforms such as personal computers, workstations, private local area networks (e.g., business entity or government entity) or other similar device that can provide network access and interact with the service portal  105 . 
         [0024]    In some embodiments, the service portal  105  can be configured to provide services. As a non-limiting example, the service portal  105  can be configured to provide information for users to research, compare and purchase software, hardware and consulting services in support of the those software and/or hardware purchases. The service portal  105  can also be configured to provide support services by subscription to those same software and/or hardware purchases. The service portal  105  can further be configured to provide a knowledgebase for a user in a community can search for answers regarding issues. The community can comprise of registered and non-registered users. 
         [0025]    The service portal  105  can be configured to provide at least the described services with a service backend  130 . The service backend  130  can comprise at least a knowledge server  110 , an issue tracker server  115  and a chat server  120 . 
         [0026]    The knowledge server  110  can be configured to provide a knowledgebase for the system  100 . The knowledgebase can comprise of Wiki pages, articles, frequently asked questions, transcripts of chat sessions, forums, and other informational items related to issues deemed worth discussing by the community. The knowledge server  110  can also be configured to search and retrieve requested informational items from third party sites such as Google™, Yahoo™, etc. The knowledge server  110  can then rank and prioritize the search results from internal and external sources for the requesting user based on a single interface provided by the server portal  105 . In some embodiments, the knowledge server  110  can be implemented on a separate server using open-source technologies. 
         [0027]    The service portal  105  can also be configured to interface with the issue tracker server  115 , which provide support services for the service portal  105 . More particularly, a user may have a problem or issue with a purchased software and/or hardware from the service portal  105 . The user can return to the service portal  105  and request support services based on a purchased service subscription through a user interface generated by the service portal  105 . The service portal  105  can redirect the support request to the issue tracker server  115 . The issue tracker server  115  can open an associated service ticket for resolution by support personnel. The issue tracker server  115  can also be configured to attach transcripts of any chat sessions between the support personnel and the user as well as documenting the solution(s) to the issue of the user. In some aspects, the documented solution can be converted into an article, added to a frequently asked question list, Wiki page, etc., and passed onto the knowledge server  110 . 
         [0028]    The chat server  120  can be configured to couple with the service portal  105 . A user with an issue or question can log into the service portal  105  and search for solutions and/or answers. The service portal  105  can generate a user interface and display an option for requesting assistance via a chat session. If a user selects this option, the service portal  105  can pass the request over to the chat server  120 . The chat server  120  can be configured to provide the chat session to the user via another user interface provided by the service portal  105 . The chat server  120  can also be configured to save the chat sessions for later review. For example, support personnel can turn the chat session into an article or extract discussed solutions in the chat sessions into or add to a frequently asked questions list. 
         [0029]      FIG. 2  illustrates a more detailed block diagram of the service portal  105  in accordance with another embodiment. It should be readily apparent to those of ordinary skill in the art that the service portal  105  depicted in  FIG. 2  represents a generalized schematic illustration and that other components may be added or existing components may be removed or modified. 
         [0030]    As shown in  FIG. 2 , the service portal  105  can comprise a user interface module  205 , a controller module  210 , a broker module  215 , a business logic module, a database interface module  225 , and a logging module  245 . The user interface module  205  can be configured to generate the graphical user interfaces (“GUIs”) for users to interact with service portal  105 . The user interface module  205  can generate the necessary functionality of the GUIS based on hypertext markup language (“HTML”) code, cascading style sheets (“CSS”) and/or Java Server Pages (“JSP”). 
         [0031]    The user interface module  205  can be configured with a controller module  210 , which is configured to provide code support for the functionality embedded in the GUIs of the user interface module  205 . More particularly, the controller module  210  can comprise DWR, Dojo, and a library of JavaScript apps. The controller module  210  can be implemented using direct web remoting (DWR). DWR can be considered a Java and JavaScript open source library which allows a programmer to write Asynchronous JavaScript and XML (“Ajax ”) web applications or interactive web applications. DWR allows generally JavaScript code in the GUI generated by the user interface module  205  to use Java methods. 
         [0032]    The Dojo component can be considered an open-source JavaScript Toolkit to construct the dynamic web user interfaces. As such, the controller module  210  can dynamically generate user interfaces to pass along to the user interface module  205  for display to a user. 
         [0033]    The library of JavaScript apps can define a list of pre-determined functionality that users are likely to call. For example, one JavaScript can be “Get Price of Product X”. 
         [0034]    The broker module  215  can also be coupled with business logic  220 , which is configured to contain the logic to provide the desired business services from the broker module  215  such as processing requests for the database  230 . The business logic module  225  can also provide a schema for inquiries to the databases  230 . The databases  230  can, abstractly, contain two databases: a user profile database  235  and a product catalog  240 . The databases  230  can be implemented using any type of database systems provided by vendors such as MySQL, Oracle, Sybase, International Business Machines, etc. The business logic module  220  can provide the schema to formulate queries to pass to the databases  230  through the database interface module  225 . The business logic  220  can be implemented using an open source lightweight framework such as Spring Application Framework supported by data access objects, beans, and manager. 
         [0035]    The broker module  215  can also be coupled with business logic module  220 , which is configured to provide a schema for inquiries to the databases  230 .

The databases  230  can be implemented using any type of database systems provided by vendors such as Oracle, Sybase, International Business Machines, etc. The business logic module  220  can provide the schema to formulate queries to pass to the databases  230  through the database interface module  225 . The business logic module  220  can be implemented using an open source lightweight framework such as Spring Application Framework supported by data access objects, beans, and manager. 
         [0036]    The database interface module  225  can be configured to provide an abstraction between the databases  230  and the business logic module  220 . The database interface module  225  can be implemented with Hibernate or other similar abstractions. The database interface module  225  provides object relational mapping and persistence management with the databases  230 . 
         [0037]    The modules  205 - 225  of the service portal  105  can also be implemented using an open source servlet container and webserver such as Tomcat™ in some embodiments. Other embodiments could use proprietary servlet container and webserver technologies. 
         [0038]    The logging module  245  can be configured to couple with the user interface module  205 , the controller module  210 , the broker module  215 , the business logic module  220  and the database interface module  225 . The logging module  245  can also be configured to provide logging and exception handling for all the coupled modules  205 - 225 . The aforementioned module can provide functions which may be commonly called by the rest of the modules  205 - 225  of the service portal  105 . The logging module  245  can be implemented using aspect-oriented programming as known to those skilled in the art. 
         [0039]      FIG. 3  illustrates a more detailed block diagram of the knowledge server  110  in accordance with another embodiment. It should be readily apparent to those of ordinary skill in the art that the knowledge server  110  depicted in  FIG. 3  represents a generalized schematic illustration and that other components may be added or existing components may be removed or modified. 
         [0040]      FIG. 2  and  FIG. 3  share some common components. As such, the description of the common components is being omitted and the description of these components with respect to the  FIG. 2  is being relied upon to provide adequate description of the common components. 
         [0041]    As shown in  FIG. 3 , the knowledge server  110  can comprise at least a user interface module  305 , a controller module  310 , a broker module  315 , a business logic module  320  and a database interface module  325 .

The functionality for selected actions by the users is provided by the controller module  310 . The controller module  310  can be configured to provide the associated code for the requested functionality of the selected action in the GUI. The broker module  315  can be configured to provide high-level business logic for the knowledge server  110 . More particularly, the broker module  315  can provide filtering for the requests entering the knowledge server  110 . For these requests, the broker module  315  can receive these requests from the service portal  105  through the server interface  335 . The server interface  335  can be implemented using simple object access protocols, web services, etc. The knowledge server  110  can also use the server interface  335  to return requested information to the service portal  105 . Unlike the service portal  105 , the knowledge server  110  can be configured to prevent direct access to the knowledge server  110  but can only be accessed through the service portal  10   5 . 
         [0043]    The broker module  315  of the knowledge server  110  can also be coupled to the business logic module  320 , which is configured to contain the logic to provide the desired business services as received from the broker module  315  such as processing requests for the database  330 . The business logic module  325  can also provide a schema for queries into the knowledgebase database  330 . The database interface module  325  can be configured to provide a level of abstraction between the queries from the broker module  320  to the actual physical implementation of the knowledgebase database  330 . As previously described, the knowledgebase database  330  can be implemented with database architectures provided by vendors such as MySQL, Oracle, Sybase, International Business Machines, and other similar manufacturers. 
         [0044]    The modules  305 - 325  of the service portal  105  can also be implemented using an open source servlet container and webserver such as Tomcat™ in some embodiments. Other embodiments could use proprietary servlet container and webserver technologies. 
         [0045]      FIG. 4  illustrates a more detailed block diagram of the issue tracker server  115  in accordance with another embodiment. It should be readily apparent to those of ordinary skill in the art that the issue tracker server  115  depicted in  FIG. 4  represents a generalized schematic illustration and that other components may be added or existing components may be removed or modified.

Other embodiments, the database  420  can be implemented using proprietary databases such as Oracle, Sybase, IBM, etc. 
         [0050]    Although  FIG. 4  depicts the user interface module  505 , controller module  510 , and the database interface module  515  as separate components, these modules ( 505 - 515 ) can be implemented using LAMP, which is an open source Web development platform based on Linux, Apache, MySQL, and PHP. 
         [0051]      FIG. 5  illustrates a more detailed block diagram of the chat server  120  in accordance with another embodiment. It should be readily apparent to those of ordinary skill in the art that the chat server  120  depicted in  FIG. 5  represents a generalized schematic illustration and that other components may be added or existing components may be removed or modified. 
         [0052]    The chat server  120  can be configured to provide chat services for users. The chat server  120  can provide a communication link between users and a group of support personnel. The users can request access to support through a GUI of the service portal  105 . Some embodiments can use Wildfire to provide group and instant messaging service using the Extensible Messaging and Presence Protocol (“XMPP”). 
         [0053]    As shown in  FIG. 5 , the chat server  120  can comprise a user interface module  505 , a controller module  210 , a database interface module  215  and a database  220 . The user interface module  505  of the chat server  120  can be configured to generate GUIs for the service portal  105  to interface thereto. The user interface module  505  can be implemented using HTML code, CSS, and/or Java Server pages. 
         [0054]    As with the knowledge server  110  and the issue tracker server  115 , the service portal  105  provides a unified interface to the chat server  120 . The service portal  105  can be configured to receive requests from users to access the chat server  115 . The received requests are processed by the chat server  120  to start a chat session with someone from a group of technical support personnel. 
         [0055]    The received requests for chats can be processed by the controller module  510 , which contains the associated code for the selected function in the GUI by a user. The controller module  510 , in some embodiments, can be implemented using DWR. 
         [0056]    The controller module  510  can also interface with a database interface module  515 . The database interface module  515  can be configured to translate queries from the controller module  510  to appropriate format of the database  520  to store and retrieve information. The information stored in the database  520  can comprise of chat sessions between users and support personnel. In some embodiments, the database  520  can be implemented with a MySQL database. Returning to the database interface module  515 , this module  515  can be implemented using plain old Java objects as known to those skilled in the art. 
         [0057]    Although  FIG. 5  depicts the user interface module  505 , controller module  510 , and the database interface module  515  as separate components, other embodiments can implement the functionality of these modules can be implemented using Tomcat Servlet container and web server from Apache Software Foundation. 
         [0058]    Returning to  FIG. 3 , the knowledge server  110  can be configured with a directed forum module  340  embedded in the controller module  310 . The directed forum module  340  can be configured to provide a forum with directed technical support. More particularly, when a user logs-in to the directed forum, the user can be presented with a GUI widget that displays a list of the logged-in members of a technical assistance (help) group. In some embodiments, the list of logged-in members can display the status of each member, whether the member is free or busy. Accordingly, the user can directly contact an available person in the technical assistance group for assistance. 
         [0059]    Alternatively, the user can input a thread with an issue in the directed forum. The directed forum module can be configured to parse the initial query of the thread for key words. The key words can be a list of predetermined terms that the moderator and/or the user community has agreed upon to be relevant to the directed forum. For example, for a directed forum about Linux support, some key words can be “Linux”, “installation”, “configuration files”, etc. 
         [0060]    With the key words from the query, the directed forum module can be configured to search the user profile of the logged-in members of the help group to search for the best available member to answer the question. As a non-limiting example, the directed forum module can be configured to search for the same key words in the user profiles of the logged-in members. The members of the help group that have highest matching key words in the user profile with the key words from the query user profiles can be considered the best available group to assist the requesting user. Accordingly, the directed forum module can notify the members of the best available group of the pending question in the directed forum either by sending a universal resource locator (URL) to the query or a copy the query via electronic communication means such as electronic mail or message. 
         [0061]      FIG. 6  illustrates a block diagram of the directed forum module  340  in accordance with yet another embodiment. It should be readily apparent to those of ordinary skill in the art that the directed forum module  340  depicted in  FIG. 6  represents a generalized schematic illustration and that other components may be added or existing components may be removed or modified. 
         [0062]    As depicted in  FIG. 6 , the directed forum module  340  comprises of a manager module  605  coupled to the user interface module  305 , the server interface  335 , the database interface module  325 , and a buffer  610 . The manager module  605  is configured to implement the functionality of the directed forum module  340  as previously described and described in greater detail below with respect to  FIGS. 7-11 . The manager module  605  can be implemented in software code (Java, C, C++, etc.), hardware device (application specific integrated circuit, field programmable gate array, microprocessor, etc.) or combination thereof. 
         [0063]    Although the manager module  605  is depicted as a separate module in  FIG. 3 , it is readily obvious to those of ordinary skill in the art that the functionality of the manager module  605  can be implemented within the controller module  310  or the broker module  315  without departing from the teachings of the present invention. 
         [0064]    The manager module  605  can access the user interface module  305  through the existing controller module  310  interfaces with the user interface module  305  as previously described. The user interface module  305  can be configured to generate GUIs to provide for the directed forum, which allow a user to post threads (queries), responses, search the threads of the directed forum, review responses/answers, and other typical functions of conventional forums. 
         [0065]    The user interface module  305  can also, among other things, provide a GUI widget (dialog box, a list view box, etc.) that displays the list of logged-in members of the technical assistance group, i.e., the help group, as shown in  FIG. 7 . As shown in  FIG. 7 , GUI widget  700  can be embedded as part of the directed forum GUI that a user sees when the user logs into the directed forum. Alternatively, the GUI widget  700  can be an overlay that is generated over the directed forum GUI. The GUI widget  700  can comprise of a title  705  and a list of logged-in and available technical support personnel  710 . The list of available technical support personnel  710  is a dynamic list as members of this group log in and out. Accordingly, the manager module  605  can be configured to add names to the list  710  as they log-in and remove names as participating members log-off. 
         [0066]    Returning to  FIG. 6 , the manager module  605  can be configured to access the database  330  through the existing pathways between the controller module  310  and the database interface module  325 . Accordingly, the manager module  605  can issue requests to the database interface  325  to search, store, and retrieve threads from the knowledgebase database  330 . 
         [0067]    The manager module  605  can be configured to use the server interface  335  to request user profile information from user profile database  235  (see  FIG. 2 ) of the service portal  105 . More specifically, the manager module  605  can invoke the request for the user profile and forward the request through the server interface  335  through the broker module  315 . The request is received at the broker module  215  of the service portal. The broker module  215  passes the request to the user profile database  235 . The return path for the retrieved user profile is the reverse of the forward path. 
         [0068]      FIG. 8  illustrates an exemplary user profile  800  in accordance with yet another embodiment. It should be readily apparent to those of ordinary skill in the art that the user profile depicted in  FIG. 8  represents a generalized illustration and that other fields may be added or existing fields may be removed or modified. 
         [0069]    As shown in  FIG. 8 , the user profile  800  can comprise of a username field  805 , an address field  810 , a user rank field  815 , a qualification field  820 , a rating field  825 , a review field  830 , and a user status field  835 . The username field  805  can indicate the name that the user has selected to be known as in the system  100 . Optionally, the user profile can contain fields for the legal name of the user. The user rank field  815  can represent a category of user such as ordinary user, technical support, technical expert, employee, vendor, etc., for the system  100 . 
         [0070]    The qualification field  820  can represent a technical resume of the user. For example, this field  820  can comprise of a description of the user&#39;s experience in Unix or Java programming, Certifications, or years of consulting for various information technology companies. 
         [0071]    The rating field  825  can represent a rating of the user given by the user community. In some embodiments of system  100 , users can be given a rating based on their participation in the system  100 . For example, the user may participate in several forums, posting answers or blogging. As a result of the participation, the other users can evaluate the postings/participation and place this rating in this field  825 . 
         [0072]    The user status field  835  can represent an availability of the user. More particularly, if the user is busy assisting another user, the user status field  835  can be set to indicate that this user is unavailable. If the user is available, the user status field  835  can be cleared to indicate availability. 
         [0073]    The review field  830  can represent a commentary of the user given by the user community. Similar to the rating field  825 , the users of the user community may provide commentary of the user such as authenticating the user&#39;s qualification based on the user&#39;s participation/postings within the system  100 . 
         [0074]    Returning to  FIG. 6 , as previously described, the manager module  605  can be configured to add names to the list of available technical support personnel  710  as they log-in and remove names as participating members on the list  710  log-off. The manager module  605  can maintain the list of available technical assistance  710  in the buffer  610 . The buffer  610  can be a reserved section of main memory of the underlying server (not shown) that serves as the computing platform of the knowledge server  110 . 
         [0075]      FIG. 9  illustrates an exemplary flow diagram  900  executed by the directed forum module  340  in accordance with yet another embodiment. It should be readily apparent to those of ordinary skill in the art that the flow diagram  900  depicted in  FIG. 9  represents a generalized schematic illustration and that other steps may be added or existing steps may be removed or modified. 
         [0076]    As shown in  FIG. 9 , the manager module  605  can be configured to monitor the log-in of users into the service portal  105 , in step  905 . For example, the service portal  105  can send a message to the manager module  605  after the user is authenticated. 
         [0077]    In step  910 , the manager module  605  can send a request for the user profile of the user to the service portal  105  to check whether the user is part of the technical assistance group (or help group). When the user profile is returned, the manager module  605  can check the user status field  715  to determine whether the user is a member of the help group. 
         [0078]    If the user is part of the help group, the manager module  605  can be configured to add the user to the help group, i.e., add the username of the user to the list  710 , in step  920 . Subsequently, the manager module  620  returns to the processing of step  905 . Similarly, if the user is not part of the help group, the manager module  605  returns to the processing of step  905 . 
         [0079]      FIG. 10  illustrates a flow diagram  1000  implemented by the directed forum module  340  in accordance with yet another embodiment. It should be readily apparent to those of ordinary skill in the art that the flow diagram  1000  depicted in  FIG. 10  represents a generalized schematic illustration and that other steps may be added or existing steps may be removed or modified. 
         [0080]    As shown in  FIG. 10 , the manager module  605  can monitor for the log-off of users, in step  1005 . For example, the service portal  105  can be configured to send a message notifying that a selected user has logged off to the manager module  605 . 
         [0081]    In step  1010 , the manager module  605  can be configured to check the username of the logged-off user with the current list of available technical assistance  710 . If there is a username match, the manager module  605  can be configured to update the list  710  by removing the matching username, in step  1015 . Otherwise, the manager module  605  returns to the processing of  1005 . 
         [0082]      FIG. 11  illustrates a flow diagram  1100  implemented by the directed forum module  340  in accordance with yet another embodiment. It should be readily apparent to those of ordinary skill in the art that the flow diagram  1100  depicted in  FIG. 11  represents a generalized schematic illustration and that other steps may be added or existing steps may be removed or modified. 
         [0083]    As shown in  FIG. 11 , the manager module  605  can monitor the directed forum for queries by users, in step  1105 . When a user posts a new thread or query, the manager module  605  can be configured to parse the query for key words, in step  1110 . More particularly, the manager module  605  can be configured to search for the key words based on a set of key words developed by the forum administrator and/or user community. The set of key words can be terms that are relevant to the directed forum. For example, a forum related to Linux can have key words such as Red Hat, installation files, configuration files, open source, etc. 
         [0084]    In step  1115 , the manager module  605  can be configured to perform a similar key word search using the key words from the query on the user profiles of users on the list of available technical assistance  710 . The manager module  605  can collate a list of users on the list  710  that have matching terms. 
         [0085]    In step  1120 , the manager module  605  can be configured to determine which member of the list of available technical assistance  710  is best suited to answer the posted query. The criteria can be a predetermined number of matches between key words of the user profile and query key words. 
         [0086]    If the manager module  605  can determine a best available personnel from step  1020 , the manager module  605  can forward the posted query or a link to the selected member(s) on the list of available technical assistance  710 , in step  1025 . Otherwise, the manager module  605  can notify all the members of the list  710  of the posted query. Alternatively, the manager module  605  can return to the processing of step  1105 . 
         [0087]    Certain embodiments may be performed as a computer program. The computer program may exist in a variety of forms both active and inactive. For example, the computer program can exist as software program(s) comprised of program instructions in source code, object code, executable code or other formats; firmware program(s); or hardware description language (HDL) files. Any of the above can be embodied on a computer readable medium, which include storage devices and signals, in compressed or uncompressed form. Exemplary computer readable storage devices include conventional computer system RAM (random access memory), ROM (read-only memory), EPROM (erasable, programmable ROM), EEPROM (electrically erasable, programmable ROM), and magnetic or optical disks or tapes. Exemplary computer readable signals, whether modulated using a carrier or not, are signals that a computer system hosting or running the present invention can be configured to access, including signals downloaded through the Internet or other networks. Concrete examples of the foregoing include distribution of executable software program(s) of the computer program on a CD-ROM or via Internet download.
