Server

• A server refers to a hardware or a software which
  is meant to provide functionality to other
  devices or programs that are known as the
  clients. Usually, if a computer shares its
  resources with client machines, it is called a
  server. A server works on a client-server model.
  It carries out many functionalities, which are
  referred to as services. Multiple clients can use
  one server as well as one client can use many
  servers. There are many types of servers, such as
  database servers, game servers, file servers,
  mail servers, print servers, application servers,
  web servers etc.

Web Server

• YELLOW
• A web server is used for storing, processing and
  delivering web contents to the clients. It is
  essentially either a server software or a system
  and consists of either one or multiple computers
  that are able to satisfy client HTTP requests
  over the Internet or over private LANs and WANs.
  A web server manages client HTTP requests of web
  resources that are related to one or many of its
  configured/served websites.
• Web servers are provided by web hosting
  companies. These companies are also called as web
  hosts and provide not only server space but also
  the technology and the services that a website
  needs in order to be accessible over the
  Internet. The Best Windows Hosting Company, the
  Best Website Hosting Company, the Top Cloud
  Hosting Company are some of the terms that are
  most frequently used to refer to the most popular
  web hosting service providers.
