![]() ![]() A computer network is mainly of four types. A computer network can be categorized by their size. Wireless LAN is formed by connecting different devices through wireless communication to form an area network.Ī computer network is a group of computers linked to each other that enables the computer to communicate with another computer and share their resources, data, and applications. Wireless LANs use high-frequency radio signals, infrared beams, or lasers to speak between the workstations, file servers, or hubs. Nowadays, more and more networks are operating without cables, within the wireless mode. Wide Area Network Advantages and Disadvantages This will reduce cost of hardware purchases. Computer hardware resources like printers, modems, DVD-Rom drives and hard disks can be shared with the help of local area networks. Public libraries and government agencies typically use a MAN. Now How the Campus Area Network is get connected?Ĭisco Network Templates. The Providing of the network at a particular location is called a Campus Area Network. Office, school, any area that presented at a limited distance is called the campus. ![]() Telecommunications are the means of electronic transmission of information over distances. Components of a Telecommunications Network. The electronic transmission of information over distances, called telecommunications, has become virtually inseparable from computers: Computers and telecommunications create value together. Telecommunications, the Internet, and Information System Architecture. It connects different LANs and other networks for communication and to share and access data from one user to another user over a longer distance.Ĭhapter 7. Merely, the network of all local area networks is called a Wide area network WAN. Ethernet and wifi fall under the local area network. A LAN is a small area network that connects the network only for a limited distance. Wide Area Network WAN is a collection of various local area networks LAN to transmit the data to the large geographical area in the form of voice, video, image, files. Local Area Network cannot cover cities or towns and for that Metropolitan Area Network is needed, which can connect city or a group of cities together. MAN networks are usually operated at airports, or a combination of several pieces at a local school. The devices in a WAN are connected through public infrastructure such as a telephone system or through leased lines or even satellites. LAN Local This type of network is large than a LAN, which is mostly limited to a single building or site. We use radio frequency for communication in this network. What is LAN? What is WAN? Chapter 1: What is a Network? It includes devices housed in a single room to millions of devices spread across the world. ![]() The size of a network should be expressed by the geographic area and number of computers, which are a part of their networks. We can categorize them according to their size as well as their purpose. There are various types of computer networks available. In ATM data is distributed online in the form of small fixed size packets. ATM Asynchronous transfer mode was developed in to transfer digital data fast. ![]() Some of these technologies are mentioned below Its range is within kms. MAN depends upon different technologies to establish a network. MAN usually involves connection of fiber optics wires to boost data transfer speed.
