What is LAN AND WAN?

The Local Area Network and the Wide Area Network re used to connect the different area either locally or worldwide. The data in the two or more than two computers can be exchanged by interconnecting the computers with the help of the LAN. The fibre optics cable is used to connect two or more than two computers. This can be done with the help of the satellites also. It helps to exchange the files and share the hardware like the printers or scanner. It leads to the advantage of saving the time and the use of hardware by using the LAN network. It enhances the speed and the ease of the communication. It is economical as it lets to share the hardware of one computer with the others also. In this way it not required to install the hardware to each and every computer separately. When more than one terminal is joined with the main computer, many other people can use the same data for the different kinds of the work. Basically network is defined as the connection of more than two computers via cable in order to share the information with it and also for the process of the communication. The networks which connect the small areas are known as the Local Area Network. There are various functions of the LAN. It helps to use the single file that is store in a main computer by the all other computers that are connected to it.

It enables to connect the data without the help of physical hardware like floppy disk. The hardware like printers and scanners that are of expensive quality can be easily shared through LAN. It can be used to send mails, memos, reports, circulars and it acts as messenger to other people at computer or also in the other part of the building of the organization. The two people or more than two people can use same document at the same time simultaneously with the help of LAN network. The LAN programs can also be used or shared among the two or more computers. It abolishes the need of the employees to pass or sign papers or the copies and hence reduces risk of loss of the files and damage. It helps in speeding up the communication and flow of the work by giving each worker the separate mails and messages on the phone. Every employee is supplied with the automatic message, agendas, appointments, direction or the notice for the meeting with the help of this networking system. It helps in storing and sorting of the data. It helps the employees to work at remote places or at the houses without attending central office on the daily basis. Since LAN is restricted to limited areas only WAN is used to connect computers of the different states, different cities or even the countries. Both the LAN and WAN can be connected to each other with the help of the devices named as gates ways. The wide area network includes the use of the large number of the computers connected with each other as compared to the LAN that has very few computers connected to each other. Since the data is needed to be transmitted over long distances hence there is the need of the modem in this case. The communication controllers are introduced to check the errors or bugs in the data transmission. WAN is complex in their application and it is multi facet as compared to the LAN that is limited in its application. The big corporations often use WAN for the process of communication with the employees and the executives.

The long distance phone calls can be saved along with the use of written documents can be stopped and time lags in the communication can also be overcome with the help of the WAN. These both types of the networks help to gain the time efficiency by reducing the time wastage by communication at the long distances without any delay. It can help to reduce the unnecessary paper work that is increased just because of the repetition of the work by the employees in an organization. The networks are very useful in now a day as it help in saving the lot of the time. The channels that are increased unnecessarily and one can bypass all those channels that are not of that importance and get to solve the problem of long distance communication. WAN has made the globalization possible. With the help of WAN one can talk to overseas and be in the contact of the organization overseas also and that too in a very less span of the time. The world seems to be very small with the help of the methods of communication like these. The LAN and the WAN networks are used to help the organization to make the communication process easy. The world has become very small with the help of the networking systems. One can easily see the other on the video calls even living in the different countries. It is also used in the organizations to send the important notices, agendas, meetings reports etc. The networking is very useful for reducing the cost of the expensive hardware. It is used to share the expensive hardware which otherwise are required to be needed with every computer. By sharing the hardware the communication process in an organization through the LAN process becomes very easy. Hence both the networking system helps to make the things and the work in an organization very easy. It is of utter importance to use this thing in a very proper way as the misuse of such things can lead to harmful things like leaking of the information from the centralized server of the organization. The proper security purpose is required to protect the data at the central server. In order to maintain the privacy policy of the organization one needs to protect the data by the strong programs that are not accessible by the normal programmers.
