A wide area network (wan) is a network that exists over a large-scale geographical area a wan connects different smaller networks, including local area networks (lans) and metro area networks (mans.
Information technology essays our information technology essay examples and dissertation examples cover a wide range of exciting it topics including network management, systems design engineering, software development, web-application development and much more. A wide area network (wan) is a telecommunications network or computer network that extends over a large geographical distance/place wide area networks are often established with leased telecommunication circuits. The information technology essay below has been submitted to us by a student in order to help you with your studies please ensure that you reference our essays correctly alternatively get in touch if you are looking for more tailored help. This report will discuss some of the characteristics that are used to classify the network, such as the connection method of the computer network, types of networks as determined by their size, scope, and purpose, as well as some of the basic hardware that is used to create a computer network.

Lans, wans, and the internet (13) most web users never consider how the internet works in this section you will begin to explore the pieces that come together to enable network communications. Technology is constantly changing, and those who keep abreast of the latest developments in information technology are the ones who will be the most successful good communication skills the soft skills of verbal and written communication are increasingly important as non-techies rely on technological tools for their everyday business. Wans use numerous types of devices that are specific to wan environments wan switches, access servers, modems, csu/dsus, and isdn terminal adapters are discussed in the following sections other devices found in wan environments that are used in wan implementations include routers, atm switches, and multiplexers. Lan, which stands for local area network, and wan, which stands for wide area network, are two types of networks that allow for interconnectivity between computersas the naming conventions suggest, lans are for smaller, more localized networking — in a home, business, school, etc — while wans cover larger areas, such as cities, and even allow computers in different nations to connect.
Information technology (it) is the use of computers to store, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise it is considered to be a subset of information and communications technology (ict.
