Computer networking is the process of providing communication facilities to computers and peripherals, in the broadest sense of the term — devices such as printers, scanners, disk drives, etc.
Computer networking is the process of providing communication facilities to computers and peripherals, in the broadest sense of the term — devices such as printers, scanners, disk drives, etc. This article is about communication between computers.
Computer networking is essentially the process of providing a computer with the right communication facilities to do the computing work for which it is designed. This is called ‘the network’.
Computer networking is closely related to a variety of other networking disciplines. The most common are LAN (local area network), WLAN (wireless local area network), Wi Fi (wireless fidelity), and Wireless LAN (WLAN). Computer networking is also closely related to ‘the internet’ and the World Wide Web (www).
Computer networking can be defined as the provision of data, voice, and graphics over the Internet. This can be achieved by using any device that has a connection to the Internet (i. , modem, router, or gateway). The use of ‘computer networking’ depends upon the information content of the data being transferred. If the data is text, then computer networking would encompass the data being transferred to a printer (and eventually to a web page) over the Internet and to a terminal over a LAN. If the data is image data, then computer networking would incorporate the data being transferred to a scanner or a file server over the Internet and to a modem over a LAN. If the data is voice data, then computer networking would encompass the data being recorded to a disk (and in some cases, to a telephone line) over the Internet and to a microphone or speaker over a LAN. Finally, if the data is video data, then computer networking would include the data being transmitted over an analog video link to a TV monitor or through video-on-demand equipment such as TiVo, TiMAX, DirectTV, or VOD.
Computer networking is a growing field whose future is increasingly dependent on communications technology. The demand for computer networking and related Internet service providers (ISPs) has doubled every 6 years since 1990.

The IEEE defines a cellular broadband network as a system of wireless coverage area with both terrestrial macro cells and microcells. The coverage area of a cellular broadband wireless network is subdivided into a large number of smaller coverage areas, each with associated base station. The smaller coverage areas are used to serve individual subscribers, while the macro cells and microcells form an extended wireless coverage area on the basis of a higher capacity and range. Cellular broadband networks are characterized by a large number of base stations, the geographical distribution of which varies depending on the type and category of subscribers, as well as the amount of spectrum available on the wireless carrier.
The IEEE defines a “transport” as the delivery of data from one point to another, either wireless or wired, via a radio communication link. This definition is based on several theoretical advantages of the wireless transmission, including the inherent randomness of radio signals. However, because the transmission from one wireless carrier to another relies on the wireless channel, this definition is not specific to any particular communication channel. The IEEE defines a “communication channel” as a link for the transmission of data. There is no inherent limitation to the number of communication channels that can be established between two points in a given area. The IEEE defines the “physical layer” as the physical layer of a radio communication interface; it includes the physical and electrical properties of the medium in which a communication operates.

Digital communications are based on encoding and decoding. This means that the communication channel is divided into a series of stages and that each stage carries digital data. The most common techniques used in the existing analog systems are described below.

Tips of the Day in Computer Networking

The idea of a network-to-the-cloud connection is well underway. It’s an idea that makes good sense if you’re trying to put your computing data on the cloud, where it’s available for all to access, analyze, and make sense of.
But the question of how to build such a connection is complicated, and in some sense may never be addressed. To make the issue even more complicated, the notion of a “physical connection” is much more complicated.
This may well be the right view of a physical, network connection between a network and the data center. In fact, it is. But let’s consider how that view of a “physical connection” is used.
This diagram might help to explain why the physical connection may or may not be the best to use for the purpose of data storage. This is part of the reason why there’s a lot of work for the networking community.
