A server is a computer that provides data to other computers. Many types of servers exist, including web servers , mail servers, and file servers.

How the web works provides a simplified view of what happens when you view a webpage in a web browser on your computer or phone. This theory is not essential to writing web code in the short term, but before long you'll really start to benefit from understanding what's happening in the background. Computers connected to the web are called clients and servers.


Different servers do different jobs, from serving email and video to protecting internal networks and hosting Web sites. Learn about the many types of servers used today. Servers are often dedicated , meaning that they perform no other tasks besides their server tasks. A proxy server sits between a client program typically a Web browser and an external server typically another server on the Web to filter requests, improve performance, and share connections. A term often used synonymously with operating system , a platform is the underlying hardware or software for a system and is thus the engine that drives the server. This entire exchange is mediated by the browser and server talking to each other using HTTP.

What are the most common file types and file extensions?

A network consists of two or more computers that are linked in order to share resources such as printers and CDs , exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams. It is generally limited to a geographic area such as a writing lab, school, or building. Computers connected to a network are broadly categorized as servers or workstations. Servers are generally not used by humans directly, but rather run continuously to provide "services" to the other computers and their human users on the network. Services provided can include printing and faxing, software hosting, file storage and sharing, messaging, data storage and retrieval, complete access control security for the network's resources, and many others.

In computing , a server is a piece of computer hardware or software computer program that provides functionality for other programs or devices, called " clients ". This architecture is called the client—server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device.

There are hundreds of different file extensions and file types used with computers, and you can find a complete list on our computer files and file extensions page. However, it would be impossible for most people to memorize all file extensions and their associated programs. Below is a list of the most common file extensions, broken into categories by type of files. There are several audio file formats, standards, and file extensions used today.

Returns the MIME content type for a file as determined by using information from the magic. Submit a Pull Request Report a Bug. Parameters filename Path to the tested file. The original expression would not work if the filename is a relative path.

Exchange use a single building block architecture that provides email services for deployments at all sizes, from small organizations to the largest multi-national corporations. This architecture is describe in the following diagram. Communication between Exchange servers and past and future versions of Exchange occurs at the protocol layer. Cross-layer communication isn't allowed.

Any user on the network can store files on the server. Servers are often dedicated, meaning that they perform no other tasks besides their Server types:​.
