7. Computer Networks Personal computers that are not connected to other computers (via network cards) are referred to as “stand-alone” computers. Institutions such as colleges find it more economical and efficient to connect up personal computers to form a computer network

8. Advantages of Computer Networks Economical Ability to have many student computer accounts to use the computer’s resources. Ability to share hardware devices such as printers and scanners. Efficient Ability to communicate among users. Efficient method to maintain and upgrade software (I.e. one copy of software on file server - therefore, only upgrade one location). Ability for users to share files.

9. Network Server A Network Server (usually called just “server”) is a powerful centralized computer with software that allows multiple users to access software applications and data files. The network server may also provide other important services such as network printer management and connection to other networks (e.g. via the Internet)

10. Network Server Other Network Servers Terminal (Client) Network Server (Central Computer) Communication Medium (e.g. Internet)
