A network is any collection of
independent computers that communicate with one another over a shared network
medium. A computer network is a collection of two or more connected computers.
When these computers are joined in a network, people can share files and
peripherals such as modems, printers, tape backup drives, or CD-ROM drives. When
networks at multiple locations are connected using services available from
phone companies, people can send e-mail, share links to the global Internet, or
conduct video conferences in real time with other remote users. When a network
becomes open sourced it can be managed properly with online collaboration
software. As companies rely on applications like electronic mail and database
management for core business operations, computer networking becomes
increasingly more important.
Every network includes:
1. At least two computers Server or
Client workstation.
2. Networking Interface Card's (NIC)
3. A connection medium, usually a
wire or cable, although wireless communication between networked computers and
peripherals is also possible.
4. Network Operating system software,
such as Microsoft Windows XP, 7,8
