What are Servers?
A server is a computer program that manages and provides services to other programs in the same or other computers. The various servers are application servers, database server, fax server, game server, communications server, file server etc. The computer in which the server program is running is also called as a server. This belongs to the hardware section of servers. A single machine by itself can act as a server or multiple machines can jointly act as a server depending on the workload and it is down to the user to determine which is the best method.
Servers act as a centralized gateway for resources and data. Moreover servers can be accessed remotely and across multiple platforms. Since multiple machines are controlled by the server, any global change can be easily made at this single location. Many servers are designed to operate over a long period of time and often unattended. Compared to the normal work station computers, servers have better hardware configurations which includes a faster CPU providing a better processing power, larger hard disk and faster RAM and uninterruptible power supply. Also software limits are often overcome in servers due to licensing.
In the computer world, servers are often used to represent the ability to handle multiple operations or requests. Since server provides services to multiple machines connected over a network, fast network connections are mandatory for efficient operations. It is not so common to see server machines with a graphical user interface. In most cases, the long running servers do not need a GUI and moreover this helps in avoiding unnecessary consumption of resources. Servers often contain multiple power supplies and hard disk as a security measure to provide backup.
Servers are normally rack-mounted and kept isolated in server rooms. The boot up time for servers is long compared to normal workstations as the special operating systems running on the server do extensive memory testing and verification. Many system checks are executed while boot up so as to reduce failure rate. Linux, FreeBSD, Solaris are some of the popular operating system for servers. Linux servers run on Linux operating system. The best example for client server model is the internet itself with millions of servers connected together and all accessing and sharing data at the same time 24 hours a day.
The size of a server varies from a Blade server with minimal physical space to a rack-mount server which can be quite large. Multiple blade servers with various functionalities are often clubbed together to provide operations similar to a multi-operational rack-mount server and many businesses have this kind of set up in a dedicated room. Intel server systems as well as software’s available in the market are designed to deliver high levels of performance. The rack mount Intel server systems are widely used for energy efficient applications. AMD servers with quad-core processors provide excellent performance-per-watt efficiencies which makes them the ideal choice for anyone who is wanting to keep running costs to a minimum whilst still taking advantage of an excellent server.
