What is a Computer Network
A computer network is a group of computers or computer like devices connected together to share the network resources like files, printers, network services etc. A typical computer network consists of users working in workstations (also called as clients, or desktops), running client Operating Systems like Windows 7 or Windows 8/8.1 and store their files inside a central network server.
Computer networks are required for network communication and network resource sharing (printers, scanners, storage spaces etc). To build and connect computer networks, we need computers (Clients and Servers) and special network infrastructure devices.
Computer networks are built using network infrastructure devices. Click the following link to see some important network infrastructure devices.
