Different types of Computer Networks are used according to the area of application. For any computer problem you can use the computer services of IMPCSUPPORT. They provide 24*7 online technical supports for 365 days. In the last article I had given you information about the common know how of computer networks. I got some emails from friends like you all who want to know about the types of computer networks. So in this article I will give you complete details about the type of computer networks.
Computer networks can be classified on much aspect like their physical extent, specific purpose, Organizational extent. There are following types of computer network: · Personal Area Network: A personal area network (PAN) is a computer network used for communication among computer and different information technological devices close to one person. Some examples of devices that are used in a PAN are personal computers, Slot Kasino
printers, fax machines, telephones, PDAs, scanners, and even video game consoles.
A PAN may include wired and wireless devices Personal network is the smallest of all networks with most of the networks not exceeding a total size of 25 feet. · Local
Area Network: A local area network (LAN) is a network that connects computers and devices in a limited geographical area such as home, school, computer laboratory, office building, or closely positioned group of buildings. Current wired LANs are most likely to be based on Ethernettechnology.
Its range is up to 12 Km. · Metropolitan area network: The Metropolitan area network (MAN) is a large computer network that usually spans a city or a large campus. Metropolitan Area network is a combination of two or Iklan Slot Online more individual Local Area Networks but with a small criterion of the boundary of the network not exceeding the city limits, thus integrating the network as a single unit within a city. Its range is about 50 Km.
· Wide Area Network: A wide area network (WAN) is a computer network that covers a large geographic area such as a city, country, or spans even intercontinental distances, using a communications channel that combines many types of media such as telephone lines, cables, and airwaves. A WAN often uses transmission facilities provided by common carriers, such as telephone companies. WAN technologies generally function at the lower three layers of the OSI reference model: the physical layer, the data link layer, and the network layer.
· Storage area network: A storage area network (SAN) is a dedicated network that provides access to consolidated, block level data storage. SANs are primarily used to make storage devices, such as disk arrays, tape libraries, and optical jukeboxes, access to servers so that the devices appear like locally attached devices to the operating system. A SAN typically has its own network of storage devices that are generally not accessible through the local area network by other devices.
The cost and complexity of SANs dropped in the early 2000s to levels allowing wider adoption across both enterprise and small to medium sized business environments.
