What is a PC?
What is a Server?
A server is a system (software and suitable computer hardware) that responds to requests across a computer network to provide, or help to provide, anetwork service.
We are already very familiar with what a personal computer
is since it has slowly become an intricate part of life for most of us. The
term was originally meant to point out slower computers that are not suitable
for the more complicated and taxing applications that are often run in a
corporate server, and are therefore restricted to personal use. This has become
largely untrue today since most personal computers are able to host almost any
kind of server.
Servers exist in a very wide variety of
configurations and applications. There are HTTP servers, DNS server, mail
servers, game server, and many more. Though it is possible to use PCs to host
servers, most of the bigger companies do not do this since the loads that they
often experience are far greater than what a regular PC can handle. For most
business applications, high end computer servers or mainframes are used to keep
thousands of users happy at the same time. These machines are way more advanced
and complex than a PC.
Servers are also kept running for extended periods of time
in order to prevent uninterrupted service to clients all over the world. This
requirement led to the development of technologies that are not common or
present in PCs. Redundancy is very essential in servers since it allows
components of the computers to fail without bringing down the whole system.
Hard drives and power supplies in a server are often redundant and can be
replaced with minimal or no disruption to the service.
Summary:
- A PC is a collection of hardware while a server can either be hardware or software.
- A single PC can host multiple servers at the same time but with a limited number of users.
- Most serious businesses utilized high end servers with hardware that are not usually found in PCs to cope with great demands.
- Servers are kept running for weeks or months at a time and requires redundant systems to cope with failure.
