Servers:
A server is a software component or dedicated hardware that can accept
requests from multiple clients; and providing suitable responses after
processing their request. The device that
makes the request and receives a response from a server is called a client. A server is a centralized machine where, multiple
clients can connect through the LAN (Land
Area Network), or over the internet
through which they can connect to a
server to request for a specific
service.
Requested
Service:
The requested service can be anything. For example, the article which you're reading was
posted by me on blogger. Server and you can read it by using a web
browser on your phone or laptop. Clients request the involved server to show the
article. And the server responds back. With the content, a server is not just a
physical computer; but rather a role that computer takes.
Types:
Let's
discuss some of the common types of servers.
Firstly an application server, next,
there is a database server. After
that is the DNS server. Also, we have a file server, mail server, and webserver.
Some servers are committed to a
specific task and are often referred to as dedicated like they are only
dedicated to handling one of those requests only. Such as one server for the website,
one server for the database, and one server for email. This can happen only in big
organizations. But in small
In organizations where the
requirements are not as much as big as large organizations, you can set up a
server to handle all those requests in a single machine that can take on the
responsibility of email, DNS and, even multiple websites.
These were the basics about Servers. I
will publish a detailed article about it.
Stay tuned.
Bye.
