Information: - Internetwork Packet Exchange (IPX) is the network layer protocol in the IPX/SPX protocol suite. IPX is derived from Xerox Network Systems' IDP. It may act as a transport layer protocol as well. - Sequenced Packet Exchange ( SPX ) is the OSI - model Transport layer protocol in the IPX / SPX protocol stack . It is a reliable , connection - oriented protocol , similar to the TCP protocol of the TCP / IP , but it is datagram rather than stream protocol . - The protocol stack is an implementation of a computer networking "protocol suite". The terms are often used interchangeably. Strictly speaking, the suite is the definition of the protocols, and the stack is the software implementation of them. - NetWare is a computer network operating system developed by Novell, Inc. It initially used cooperative multitasking to run various services on a personal computer, using the IPX network protocol. - The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a "network of networks" that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing. - Open Systems Interconnection (OSI) is an effort to standardize computer networking that was started in 1977 by the International Organization for Standardization (ISO), along with the ITU-T. - IPX/SPX stands for Internetwork Packet Exchange/Sequenced Packet Exchange. IPX and SPX are networking protocols used primarily on networks using the Novell NetWare operating systems. - The Internet protocol suite is the conceptual model and set of communications protocols used on the Internet and similar computer networks. It is commonly known as TCP/IP because the original protocols in the suite are the Transmission Control Protocol (TCP) and the Internet Protocol (IP). It is occasionally known as the Department of Defense (DoD) model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense. - Novell, Inc. was a software and services company headquartered in Provo, Utah. It had been instrumental in making Utah Valley a focus for technology and software development. Novell technology contributed to the emergence of local area networks, which displaced the dominant mainframe computing model and changed computing worldwide. - A computer network or data network is a telecommunications network which allows nodes to share resources. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media. The best-known computer network is the Internet. - The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. - In computer networking, the transport layer is a conceptual division of methods in the layered architecture of protocols in the network stack in the Internet Protocol Suite and the Open Systems Interconnection (OSI). The protocols of the layer provide host-to-host communication services for applications. It provides services such as connection-oriented data stream support, reliability, flow control, and multiplexing. - In Connection-oriented communication, a data stream is a sequence of digitally encoded coherent signals (packets of data or data packets) used to transmit or receive information that is in the process of being transmitted. - In telecommunications and computer networks, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share an expensive resource. For example, in telecommunications, several telephone calls may be carried using one wire. Multiplexing originated in telegraphy in the 1870s, and is now widely applied in communications. In telephony, George Owen Squier is credited with the development of telephone carrier multiplexing in 1910. 'sequenced packet exchange' is related to which object entity through the relation of 'instance of'? Choices: - agency - area - communication - communications protocol - computer - computer network - conceptual model - cooperative - data - definition - exchange - function - government - information - internet - internet protocol - method - model - network operating system - operating system - organization - personal computer - process - protocol stack - public - range - resource - sequence - software - stack - standardization - suite - system - technology - telecommunications network - transport - valley - wire
**Answer**
communications protocol

*Question*
Information: - Roman Conrad Pucinski ( May 13 , 1919 -- September 25 , 2002 ) was an American Democratic politician from Chicago , Illinois . He was a U.S. Representative from 1959 to 1973 and alderman from the 41st Ward of Chicago from 1973 to 1991 . He was considered a longtime leader of Chicago Polonia and was seen to represent its interests in Washington along with Congressman Dan Rostenkowski . - An alderman is a member of a municipal assembly or council in many jurisdictions founded upon English law. The term may be titular, denoting a high-ranking member of a borough or county council, a council member chosen by the elected members themselves rather than by popular vote, or a council member elected by voters. - A county is a geographical region of a country used for administrative or other purposes, in certain modern nations. The term is derived from the Old French "conte" or "cunte" denoting a jurisdiction under the sovereignty of a count (earl) or a viscount. The modern French is "comte", and its equivalents in other languages are "contea", "contado", "comtat", "condado", "Grafschaft", "graafschap", "Gau", etc. (cf. "conte", "comte", "conde", "Graf"). - The Chicago metropolitan area, or Chicagoland, is the metropolitan area associated with the city of Chicago, Illinois, and its suburbs. With an estimated population of 9.4 million people, it is the third largest metropolitan area in the United States. Chicagoland is the area that is closely linked to the city through geographic, social, economic, and cultural ties. - Chicago (or ), officially the City of Chicago, is the third-most populous city in the United States, and the fifth-most populous city in North America. With over 2.7million residents, it is the most populous city in the state of Illinois and the Midwestern United States, and the county seat of Cook County. The Chicago metropolitan area, often referred to as Chicagoland, has nearly 10million people and is the third-largest in the U.S. - Daniel David "Dan" Rostenkowski (January 2, 1928 August 11, 2010) was a United States Representative from Chicago, serving from 1959 to 1995. He became one of the most powerful legislators in Washington, especially in matters of taxation, until he went to prison. A Democrat and son of a Chicago alderman, Rostenkowski was for many years Democratic Committeeman of Chicago's 32nd Ward, retaining this position even while serving in Congress. 'roman pucinski' is related to which object entity through the relation of 'position held'? Choices: - 4 - alderman - count - graf - united states representative
**Answer**
