Majority of us are familiar with the word
"server". In numerous places, such as schools, offices, universities,
and hospitals, there is a Computer Server that is used to connect the
Computers. But what is the actual purpose of a Computer Server? Read on to
learn in detail about what it is.
"Cannot
establish connection to server", "The server is down", and
the likes... errors of this kind have become commonplace in today's
gadget-dependent world. But what is the server that these errors refer to, and
what is its place in a network or an organization's infrastructure? The
solution to this could be one of two things listed below -
► A physical computer, whose assignment is to
provide services to all terminals or computers connected to it, like grant
permission or allocate resources.
► An element in the client/server
programming model, where the server is a software or a program, running on one
or multiple computers, that manages resources and services of the network,
while handling requests from different computers to access said resources.
Features of a Computer Server
From the definition of a Server, it is clear this is no
ordinary, everyday computer and hence, its hardware should match up to the
requirements of today's needs.
An ideal server machine should:
- Have a powerful RAM or Memory - To handle different requests from different computers and perform operations at a speedy/rapid pace, with effectiveness, it requires a lot of RAM.
- Optimum processor speed – Its needs to be sufficient to execute all the commands requested by other machines and multitask jobs.
- High-capacity hard drives and storage - Data can be stored on the server in any form and it should be capable of storing large amounts of data.
- Cooling fans to keep the constantly flow of high temperature of such an overworked machine, low. With powerful hardware, it is possible for the server to get overheated and lose power.
- An effective operating system - The Operating System of a server should be capable of handling its multiple operations and should be stable. Linux is one of the most preferred Operating Systems for servers.
- Fault tolerant, reliable and sturdy machine ware - A server should not fail or shut down because of faulty hardware. It should be reliable and fail-secure. In view of this, it needs steadfast hardware parts and components, which will not break down from overuse.
- An Uninterrupted Power Supply - Server operations are time-sensitive and delicate. For continuous performance, the server shouldn't suffer from power failures due to an unreliable power source. Therefore, an inverter must be set up to keep servers abuzz even when the power goes out.
- Redundant hardware - It never fails to have a backup and in case of a server machine, which should always be on, having backup hardware will come in handy in crucial situations. In case one hard drive fails, there should be a backup drive that can work in its place.
