Servers

Overview

A server is a combination of hardware and software that connects several computers across a network. A server allows everyone connected to a network to access the same information and answer all data requests. In essence, a server is designed to hold all the information related to the organization in one spot.

There are also servers that handle specific purposes within a network like web servers that handle Internet requests, print servers designed for printing documents, and mail servers for email purposes. Having all of those different servers reduces the pressure of the main server and better protects company information.

How It Works

The functioning of a server is actually quite simple. A server acts as the center of an organization and is connected to all the computers on the network. When a computer contacts the server to retrieve a document that it needs, the computer actually sends an information packet to the server that contains a request for data, services, or acknowledgement of receipt. The server then responds to the request by sending one or more packets of information, which are then used by the computer that accessed the server.
A personal computer can also act as a server. For instance, if you are sharing information on your computer, then your system becomes a server. However, actual servers are better to use because they can handle continuous data requests quickly and generally have larger hard drives.

Benefits

When 15 or more computers are connected to a network, using a server to handle the transmission of data has many benefits. One of the biggest benefits is that servers provide a synchronization of data that is needed when there are so many users handling the same information. A server also provides network security by providing appropriate access to the users of the network according to their work.

Costs

The cost of a server can vary depending on the type and capabilities of it. A basic server will cost only a few hundred dollars whereas an updated server model can cost thousands of dollars. The size of the server will also vary depending on the needs of the organization and is also an important factor in cost.

Timing

A server may not be required for home networks because the number of users is less than in a business. Remember, a server is best used when there are 15 or computers in use. A network becomes slower and unmanageable as the number of users increases, so if you find your network is becoming unstable, it might be time for your business to purchase a server. Also keep in mind that a company can use more than one server depending on the size of the information and data being accessed by the company.
