Computer Network Terms



Below are some important terms used in Computer Networking:


Domain Name System (DNS)

DNS is a directory service that provides a mapping between the name of a host on the network and its numerical address. DNS is required for the functioning of the internet. DNS is a service that translates the domain name into IP addresses. This allows the users of networks to utilize user-friendly names when looking for other hosts instead of remembering the IP addresses. For example, suppose the FTP site at EduSoft had an IP address of 132.147.165.50, most people would reach this site by specifying ftp.EduSoft.com. Therefore, the domain name is more reliable than IP address.


Uniform Resource Locator (URL)

A Uniform Resource Locator, more commonly known as a URL, is the global address of documents and other resources on the World Wide Web. It is the mechanism used by browsers to retrieve any published resource on the web. For example, www.webopedia.com is the URL used to locate this website. A URL is the most common type of Uniform Resource Identifier (URI), the generic term used for all types of names and addresses that refer to objects on the World Wide Web. An IP address can be directly used in replacement of a URL, but since it's relatively inconvenient, it's not often used.


Hyper Text Transfer Protocol (HTTP)

The Hypertext Transfer Protocol (HTTP) is an application layer protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser.


Simple Mail Transfer Protocol (SMTP)

Simple Mail Transfer Protocol is a set of communication guidelines that allow software to transmit an electronic mail over the internet is called Simple Mail Transfer Protocol. It is a program used for sending messages to other computer users based on e-mail addresses.


File Transfer Protocol (FTP)

FTP is a standard internet protocol provided by TCP/IP used for transmitting the files from one host to another. It is mainly used for transferring the web page files from their creator to the computer that acts as a server for other computers on the internet. It is also used for downloading the files to computer from other servers. It provides the sharing of files, used to encourage the use of remote computers and also transfers the data more reliably and efficiently.


Active Server page (ASP)

ASP uses scripting on the server to generate content that is sent to the client's web browser via HTTP response. The ASP interpreter reads and executes all script code between <% and %> tags, the result of which is content generation. These scripts were written using VBScript, JScript, or PerlScript. The
