Devices: a thing made or adapted for a particular purpose, especially a piece of mechanical or electronic equipment. Server:a computer or computer program which manages access to a centralized resource or service in a network. web Server:A Web server is a program that uses HTTP (Hypertext Transfer Protocol) to serve the files that form Web pages to users, in response to their requests, which are forwarded by their computers' HTTP clients. Dedicated computers and appliances may be referred to as Web servers as well. Modem: a combined device for modulation and demodulation, for example, between the digital data of a computer and the analogue signal of a telephone line. Router: A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. ... The most familiar type of routers are home and small office routers that simply forward IP packets between the home computers and the Internet.\ Router: ISP. Stands for "Internet Service Provider." An ISP provides access to the Internet. Whether you're at home or work, each time you connect to the Internet, your connection is routed through an ISP. ... When you connect a modem to the telephone or cable outlet in your house, it communicates with your ISP. Domain Name Server: Domain Name Servers (DNS) are the Internet's equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses. Protocols: Protocol, in computer science, a set of rules or procedures for transmitting data between electronic devices, such as computers. In order for computers to exchange information, there must be a preexisting agreement as to how the information will be structured and how each side will send and receive it. TCP: TCP (Transmission Control Protocol) is a standard that defines how to establish and maintain a network conversation via which application programs can exchange data. TCP works with the Internet Protocol (IP), which defines how computers send packets of data to each other. Ip: An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. ISp: An ISP (Internet service provider) is a company that provides individuals and other companies access to the Internet and other related services such as Web site building and virtual hosting. LAN: A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. ... Ethernet and Wi-Fi are the two most common technologies in use for local area networks. RAN: A radio access network (RAN) is the part of a telecommunications system that connects individual devices to other parts of a network through radio connections. A RAN resides between user equipment, such as a mobile phone, a computer or any remotely controlled machine, and provides the connection with its core network. WAN: A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs). Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites. HTTP: HTTP. (HyperText Transfer Protocol) The communications protocol used to connect to Web servers on the Internet or on a local network (intranet). Its primary function is to establish a connection with the server and send HTML pages back to the user's browser. Html: HTML. Stands for "Hypertext Markup Language." HTML is the language used to create webpages. "Hypertext" refers to the hyperlinks that an HTML page may contain. ... Below is an example of HTML used to define a basic webpage with a title and a single paragraph of text. CSS: CSS. Stands for "Cascading Style Sheet." Cascading style sheets are used to format the layout of Web pages. They can be used to define text styles, table sizes, and other aspects of Web pages that previously could only be defined in a page's HTML. Bit: A bit (short for binary digit) is the smallest unit of data in a computer. A bit has a single binary value, either 0 or 1. ... Half a byte (four bits) is called a nibble. In some systems, the term octet is used for an eight-bit unit instead of byte. Browser: browser - Computer Definition. Also known as Web browser. A client software program that runs against a Web server or other Internet server and enables a user to navigate the World Wide Web (WWW) to access and display data. ... Currently popular browsers include Internet Explorer (IE), Mozilla, and Netscape Navigator.
