A server is a central computer that offers processing services or data to a network of computers. A server serves as the central hub of a client-server network. The other computers, referred to as clients, are linked to the server through communication connections. (2) It is in charge of arranging client-to-client communication. Each time a client wants to send data to another client, it sends the request to the server. The server responds by communicating with the other client. Servers may also have access to large stores of information stored on other servers or on physical media such as disks. These sources of information are called databases.
The term "server" comes from the same root word as "service". In this context, a "server" provides service for others by handling requests and performing actions as instructed via the HTTP protocol. Some examples of servers include Apache, IIS, and Microsoft's Windows Server.
There are two types of servers: host servers and proxy servers. Host servers are computers that provide services directly to other computers - they are the origin of the request. Proxy servers act as agents for other computers; they forward requests from clients to host servers and back again when necessary. Proxies can be used to disguise the actual location of hosting services while still allowing web browsers to find them easily via DNS.
Hosting providers must install servers on their hardware to allow other people's websites to be viewed online. These servers are available for rent at affordable prices.
A server, a fast computer with a huge amount of memory and storage capacity, is at the core of most networks. The server is in charge of information exchange between networked devices such as computers, printers, and other servers. An Internet Service Provider (ISP) connects a user to the Internet via their server. Most ISPs have several hundred or thousands of these servers which are responsible for connecting users to websites, email providers, and other ISP services.
A website is a collection of files stored on a server somewhere on the Internet. These files include images, graphics, videos, applications, etc. Users access websites by typing its address into their web browser. So, a website has two components: a domain name and a web server. The domain name is what people see when they type in a URL (Uniform Resource Locator). For example, Google's domain name is google.com. Facebook uses facebook.com. A company can register any word or phrase as a domain name provided it isn't already registered by someone else. For example, Microsoft owns microsoft.com but you can still register your own website name including dots (periods), underscores, hyphens, and capital letters.
A web server is a computer program that provides space on its hard drive for others to use as a file repository. Any computer connected to the Internet can be a web server, but not all web servers will necessarily serve files back to every user who requests them.
The Internet is made possible by Internet servers. Every machine on the Internet is either a server or a client. Clients who visit a server machine have a certain purpose in mind, thus they send their requests to a specific software server running on the server machine. The software server then sends information back to the client.
Servers are usually large computers that hold many programs and data files for other computers to use. Most people think of websites as servers because they hold pages that can be downloaded by visitors. But any computer can work as a server, including your own personal computer. You can make an Internet server by installing a program called an "Internet server" on one of your computers. Then anyone who knows the address of this computer's IP address (a number that identifies it on the Internet) can access the files it stores.
Your computer is always listening for messages to come in, just like a phone. However, instead of receiving calls, it's waiting for connections from other computers. When someone does connect, you receive notification in the form of a message window.
You can also use your computer as a client, meaning that it will search for files stored on other computers. To do this, it must first find an available server.
