The computer network is a fundamental tool of our corporate environment. Computer networking is the connecting of two or more computers that allows them to share resources. It can be done between computers in a home, in a business, across a corporation, and even internationally. Anyone who has ever sent an e-mail has used computer networking. The Internet is the largest example of computer networking because it involves thousands of networks of computers that share information.
Computer networks function on a local area (LAN) or a wide area (WAN) based upon the number of people and the geographic distances involved. These can include a small business with two or three employees to major corporations to the Federal government of the United States. But computer networks exist in realms beyond business. Virtually every aspect of today's society depends on information that is furnished through computer networks. Companies can save millions of dollars by sharing resources via computer networks rather than by shipping or traveling. Individuals use computer networking to do their banking from home, communicate with relatives, and even to entertain themselves with music or by playing video games.
