What is LAN in information technology?
A geographically limited communication network that connects users within a defined area. A LAN is generally contained within a building or small group of buildings and is managed and owned by a single enterprise. Transfer data or software to or from other systems attached to the network. …
What is wan in information technology?
A communications network that connects computing devices over geographically dispersed locations. While a local-area network (LAN) typically services a single building or location, a WAN covers a much larger area such as a city, state or country.
How does a local area network work?
A local area network (LAN) consists of a series of computers linked together to form a network in a circumscribed location. The computers in a LAN connect to each other via TCP/IP ethernet or Wi-Fi. A LAN is normally exclusive to an organization, such as a school, office, association or church.
Which device is used in local area network?
Routers are one of the most commonly used connection devices. They are used to send data signals across the internet. Routers work by storing the addresses of computers on the network.
How does a LAN work?
How LAN is useful?
A local-area network (LAN) connects the computer hardware in a localized area such as an office or home. Devices connected to a LAN are able to access data from any machine that’s connected to the network. LAN users can communicate with each other by chat or email.
What is the difference between LAN and WAN network?
A LAN (local area network) is a group of computers and network devices connected together, usually within the same building. A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and relatively expensive.
What are the characteristics of local area network?
Characteristics of LAN
- It is a private network, so an outside regulatory body never controls it.
- LAN operates at a relatively higher speed compared to other WAN systems.
- There are various kinds of media access control methods like token ring and ethernet.
What do you mean by local area network?
What Is a LAN? A local area network (LAN) is a collection of devices connected together in one physical location, such as a building, office, or home. A LAN can be small or large, ranging from a home network with one user to an enterprise network with thousands of users and devices in an office or school.
How is LAN used in small geographical area?
LAN are used in small geographical area. LAN is capable in transferring data in a very fast speed that can up to 10Mbps in limited network distance. There are two types of network architecture that can be implemented in the local area network, peer-to-peer networking and client-server networking.
Which is the most common local area network protocol?
There are many different kinds of protocols, the most common protocol used in the OSI data link layer in LAN are Ethernet and Token Ring. Ethernet is the most well-known type of local area network that most widely installed in offices, home offices and companies. The standard of an Ethernet is IEEE 802.3.
How did the first Local Area Network evolve?
The first local area networks evolved in environments in which the distances to be spanned by the network were within the .range of inexpensive high-speed digital communication technologies. Today, the relationship has been turned around,
