Human beings react to many different kinds of informatin and develop different conceptual systems to deal with them. Data structure and data is another difference. Human beings must be capable of linking extremely divergent kinds of information. Computers can be used as a communication link with others. There are many different social uses of a personal computer system.
Electronic mail is a widely used way of communicating over the computer.
Networking, electronic bulletin boards, and chatting are also ways of communicating through the computer. Electronic yellow pages, electronic shopping, storefront medicine and first aid, electronic banking, home security, and travel and entertainment reservations can also be accessed through a personal computer. Through electronic mail, personal computers allow new friendships and new patterns and styles among communications. They also provide access to a variety of information, such as shopping, medical information, and more efficient financial and security systems. There are, however, social consequences of owning a personal computer.
