A server is a software or hardware device which accepts requests made over a network and responds to them. A client is called the computer that makes the request and receives a response from the server. The term "server" on the Internet typically refers to a computer device that accepts web file requests and sends those files to the client.
Network resources control servers. A user can, for example, set up a server to monitor network access, send / receive emails, handle print jobs, or host a website. They are also specialised in the execution of severe calculations. Some servers are devoted, also referred to as dedicated, to a particular mission. Many servers today, however, are shared servers that, in the case of a web server, assume responsibility for e-mail, DNS, FTP, and even several websites.
Most servers are never switched off because they are widely used to provide services that are constantly needed. Consequently, when servers malfunction, they may create several issues for network users and companies. Servers are usually set up to be fault tolerant to mitigate these problems.
The following list contains links to various server types.
The server connects to a router or switch that is used by all other computers on the network via a local network. Other computers can access the server and its features until they are connected to the network. For example, a user might link to a server with a web server to access a website, search, and interact on the network with other users.
An Internet server, but on a much larger scale, operates the same way as a local network server. An IP address is allocated by InterNIC or a web host to the server.
Typically, users connect to a server that is registered with a domain name registrar using its domain name. When users connect to a domain name (such as 'computerhope.com'), a DNS resolver can automatically convert the name to the IP address of the server.
Since the name is easier to remember than an IP address, the domain name makes it easier for users to connect to the website. Domain names often allow the server operator to modify the server's IP address without changing the way the server is accessed by users. The domain name, even though the IP address changes, will still stay the same.
