Collection of devices that allow a network computer, server, someone else, network device, accessory, or other interconnected data exchanger. An example of a network is the Internet, which communicates with millions of people around the world. A server is a computer designed to process requests and provide information to another computer via the Internet or local network. Internetworking is the connection of computer networks through gateways and routers. There is various type of work in the network that is why also different types of server have. For Example- Network Design, Network Server, Router Configuration, VLSMs, Troubleshooting, easy subnetting, internetworking operating system, IP Addressing, Routing And Configuration. We call the exchange of data between multiple computers a network. We exchange data through a special computer that is the server computer and from that data is sent to another. There are separate computers used for servers such as web server, DNS server, proxy server, mail server, firewall, FTP server. Every network works differently because It is not possible to maintain core of a network. Our custom network is connected computer to computer by Local area network and resource sharing each other. we need to secure our information. so obviously need to know about the computer network and security.
