What is LAN and its purpose?

Local area networks (LANs) are computer networks ranging in size from a few computers in a single office to hundreds or even thousands of devices spread across several buildings. They function to link computers together and provide shared access to printers, file servers, and other services.

What are MANs used for?

MANs are used to build networks with high data connection speeds for cities and towns. The working mechanism of a MAN is similar to an Internet Service Provider (ISP), but a MAN is not owned by a single organization. Like a WAN, a MAN provides shared network connections to its users.

What is the main purpose of a network?

A computer network comprises two or more computers that are connected—either by cables (wired) or WiFi (wireless)—with the purpose of transmitting, exchanging, or sharing data and resources.

What are advantages of LAN?

Advantages of LAN

  • Resource Sharing. Sharing of resources such as hard disk drives, DVD drives and Printers are made easy in Local Area Network.
  • Software Sharing.
  • Convenient Communication.
  • Centralized Data.
  • Improved Security.
  • Internet Sharing.
  • Computer Identification.

Is a switch a node?

A node is any physical device within a network of other tools that’s able to send, receive, or forward information. Modems, switches, hubs, bridges, servers, and printers are also nodes, as are other devices that connect over Wi-Fi or Ethernet.

What is the advantage and disadvantage in using LAN connection?

Easy and Cheap Communication: Data and messages can easily be shared with the other computer connected to the network. Centralized Data: The data of all network users can be stored on a hard disk of the central/server computer. This help users to use any computer in a network to access the required data.

What is an example of LAN?

Examples of Local Area Network (LAN) Networking in home, office. Networking in school, laboratory, university campus. Networking between two computers. Wi-Fi (When we consider wireless LAN).

What are the disadvantages of metropolitan area network?

Disadvantages of a Metropolitan Area Network (MAN) Metropolitan Area Network (MAN) cannot work on traditional phone copper wires; it works with optical fibers which are a little costlier to set up. In case it is installed with copper wires then the speed will be very slow.

What are some example of metropolitan area network?

Examples of metropolitan area network (MAN) Some of the examples of MAN are:-Digital cable television; Used in government agencies; University campuses; Cable broadband; Used to connect several branches of the local school; In hospital (for communication between doctors, research offices, labs) A network of fire stations; In airports

What are the characteristics of metropolitan area network?

A metropolitan area network (MAN) is similar to a local area network (LAN) but spans an entire city or campus. MANs are formed by connecting multiple LANs. Thus, MANs are larger than LANs but smaller than wide area networks (WAN). MANs are extremely efficient and provide fast communication via high-speed carriers, such as fiber optic cables.

What do you mean by Metropolitan Area Network?

A metropolitan area network (MAN) is a computer network that interconnects users with computer resources in a geographic region of the size of a metropolitan area.
