What are the different types of networks? Explain in detail.
Answer:
-Today when we speak of networks, we are generally referring to two primary categories: Local area networks (LAN) and wide-area networks (WAN).
-The category into which a network falls is determined by its size.
-A LAN normally covers an area less than 2 mi; a WAN can be worldwide. Networks of a size in
between are normally referred to as metropolitan area networks and span tens of miles.
-A local area network (LAN) is usually privately owned and links the devices in a single office, building, or campus. LANs are designed to allow resources to be shared between personal computers or workstations. The resources to be shared can include hardware (e.g., a printer), software (e.g., an application program), or data. A common example of a LAN, found in many business environments, links a workgroup of task-related computers, for example, engineering workstations or accounting PCs.
-A wide area network (WAN) provides long-distance transmission of data, image, audio, and video information over large geographic areas that may comprise a country, a continent, or even the whole world.
-A metropolitan area network (MAN) is a network with a size between a LAN and a WAN. It normally covers the area inside a
town or a city. It is designed for customers who need a high-speed connectivity, normally to the Internet, and have endpoints spread over a city or part of city. A good example of a MAN is the part of the telephone company network that can provide a high-speed DSL line to the customer.
