A computer network and its components

In this article, I will shed light on a computer network, its structure, types and components. I will explain what kinds of devices are used, who take advantage of the network environment, how a network is technically organized and maintained and what is involved in troubleshooting a network.

A computer network is a setup where all computers, laptops, printers, scanners, tablets and all other devise are connected to each other in a workgroup or server environment. A work group environment is a network where all the computers and devices work independently meaning all computers have a stand alone status but they are connected to each other. Storage and printers can be shared in this environment. In this type of network just to access files by different users at the same time. There are mostly three sizes of networks, small, medium and corporate network environment. Computer devices in a network are generally connected with each other with either wire or wifi via routers and switches. A router is a device which is used to network devices together. A router has multiple client ports to help connect computers in LAN environment. There is one port for wan connection which can be used to either connect the router to another router or to an ISP modem. A router has many functions. it can be setup for static or dynamic ip addresses or it can be used as a firewall etc. A switch is a device that can mostly be used the same way as the router but with limited functionality like assigning static ip addresses to connected devices. There are different types of networks LAN, PAN, MAN and WAN.

The main purpose of a network is, to be able to make the staff use and share resources in an office or business environment. In a server based environment, users use client computers to connect to server and store and share different resources like files, printers, applications, scanners and data. A network environment is also useful for communication like messaging and emails. Exchange server is used for email storage where all the users from CEO to a worker, take advantage of the email system. Exchange server saves all the email data related to users and email senders. The other important usage of a network is the data storage. All users are registered on the server. They have folder allocations where their personal data can be saved. Every user has specific permissions to data folders on server. Administrators set things up for network users. They give them specific permissions so that one user can’t access other user data. This is done by different methods allowed by the server operating system. The server authenticates users before give them access to the server environment. This way, it is a safe work environment. Users at all level are possibly able to access and use other devices like printing documents, copying and scanning important correspondence. Server also allows VPN advantages to users.
