These days, access to software, file storage and email is shifting from desktop to Web sites accessible from any Internet-connected computer.
Web sites are the servers that respond to requests from Web clients.
Client-server communication is used when surfing the Web for information, multimedia or a search engine. When using a Web-based service, accounts are set up on the Web site of the service provider. The information users create through the service gets stored on the Web server instead of a hard disk. Therefore, any Web client on an Internet-connected computer allows access to personalized information. Whether at home, work or Net cafe, the service recognizes the account with all the information readily available.
