What is server?

web servers and computers

server is both a running instance of some software capable of accepting requests from clients, and the computer such a server runs on. The clients may run on the same computer, but typically connect to the server through a network

In a technical sense, a server is an instance of a computer program that accepts and responds to requests made by another program; known as a client. Less formally, any device that runs server software could be considered a server as well. Servers are used to manage network resources.

Some servers are committed to a specific task; often referred to as dedicated. Most servers are never turned off. Consequently, when servers fail, they cause the network users or company many problems.Servers are named after the primary functions they perform: file servers receive, store, and send files, web servers store webpages, mail servers receive, store, and forward emails, etc.

The history of servers moves parallel to the history of computer networks. The computer networks allow multi systems to communicate with each other at the same time and its evolution was expected to assign some computers with some serving role where all other computers that are in direct interaction with the human users, perform as clients. Servers have grown along with the development and growth of networks. To do the job of serving, servers and associated software are manufactured.

Types Of Sever

Typically servers are of four types:

  • FTP servers
  • proxy servers,
  • online game servers and
  • web servers.
  • Server networking model or client is used by many systems together with email services and web sites. Peer to peer networking, a substitute model, makes all computers to work like servers and clients.

Simplify Information

File servers provide a centrally-located pool of disk space for network users to store and share various documents. These servers help organizations maintain single versions of files across departments and can simplify administration. When all the data is stored in one location, administrators need only backup files from one computer, which can often save both time and headaches should things fail to load properly or update inconsistently across employee platform.

Data Management

Organizations with hundreds of employees running numerous linked devices. Network administrators can save themselves a lot of trouble by installing updates for things like printer software and virus security patches just once, then letting the server automatically impart those changes to all connected machines.

Server Benefits

So now that you know what makes up a server, what can a server do for you? Some of the more important ones are the following:

  1. File and Network security
  2. Increased reliability
  3. Centralized data storage and shared resources
  4. Virus Management
  5. Centralized Backup

 Before investing in server hardware, you need to consider applications, storage, processor, form factor, and more to help you choose wisely.
