Understanding, Function and Purpose of LAN Network on Computer Network – Local Area Network

Understanding LAN Network (Local Area Network)

Computer news – Local Area Network or LAN network is a computer network that has a very small network coverage area. Local network coverage includes only a network of contacts, computer lab networks, school networks,  agen poker, campus networks, home networks or just one building. The LAN network will usually connect several computers in an adjacent area, such as a computer in the administrative room with a computer in the principal’s office, or connect several computers in a laboratory so that the movement and exchange of data can be done quickly and easily.

LAN Network Function (Local Area Network)

LAN network or local network serves to connect multiple computers in one location in order to connect to each other so it will facilitate the exchange of data and speed up the work process. With this lan network all the work can be done quickly and easily because we can access data from any computer, besides lan network will also save costs because the existing devices on the LAN network can be used together by using sharing techniques such as sharing Printer, file sharing and others. Here are the functions and benefits of a LAN network:

– Speed up the process of data exchange in the network (data sharing)
– More efficient and efficient because devices can be shared across a network (eg printers, servers, etc.)
– Allows the information and data to keep up to date so that if there is update data in the network can be done quickly and easily


The purpose of LAN (Local Area Network)

The main goal in a LAN network is to connect two or more computers in a network so that it can exchange information. For more details here is the purpose built LAN network:

– Connecting between computers in a single region / location

– Communication between computers and devices in the network

– Resource Sharing / sharing data and programs

– Saves financing because devices can be shared across a network


Characteristics of LAN Network (Local Area Network)

LAN network has the following characteristics:

– Has a higher data rate because it is only within the scope of one region only

– Covering a narrower geographic area (in offices, campuses, schools or homes)

– No telecommunication lines required from telecom operators (no internet access required)

Working Principles LAN Network (Local Area Network)

Working Principles LAN can be interpreted as a network or network of a number of computer systems whose location is limited in one building / location, a building complex or a campus and does not use the media public communication facilities such as telephone, but the owner and manager of the communication media is the owner of the LAN itself. The above definition we can know that a LAN is limited by the physical location. The use of LAN itself resulted in all computers connected in the network can exchange data or in other words related. Cooperation is growing from only data exchange to the use of equipment together. LANs that generally use hubs / switches, will follow the working principle of the hub itself. In this case it is that the hub has no knowledge of the destination address so that broadcasting of data is broadcast, and also because the hub has only one collision domain so that if one port is busy then the other ports have to wait. That is among the advantages and disadvantages of LAN networks

Examples of LAN networks and their Implementation

– Network within the school
– Computer network office
Computer Network in campus environment
