Previously, when two persons were prepared to share information between one another, these were counting on movable disks for example diskettes and CD-ROM. These methods for transmitting data between remote computers are frequently difficult particularly if the files is going to be transmitted very frequently.
Due to the above difficulties in transmitting data across movable disks, the thought of networking several computer continues to be come to light. Rather of transmitting the files across movable disks, the computers are linked to one another by cables through ports on the pc. If somebody must transmit the information to a different computer, he simply can share the files he must transmit over the network. By doing this no movable disk is required and also the matter is simpler.
When speaking about computer networking, you have to differentiate between your many different kinds which exist for that network. The pc network could be classified based on the geographical area they occupy or based on the manner they’ll behave when discussing and being able to access data between your computers within the network.
Let’s first observe how they’re classified based on the geographical area. This is of the classification is when much the network will occupy or just what how big the network is. You will find three types for just about any systems based on this classification. Those are the LAN, WAN, and MAN. The LAN (Lan) has got the tiniest size with regards to the other forms. The LAN can occupy an area, the ground, a structure for example company, or for the most part several adjacent structures. The Person (Metropolitan Area Network) can occupy an entire city or perhaps a while condition. However, the WAN can occupy an entire country, number of countries, or perhaps the world.
The 2nd classification is based on the data distribution over the network and just how the machines linked to one another are treated. There two kinds of systems based on this classification. The first is peer to see network. This is of the classification is the fact that all computers within the network are treated as equal. Thus how big the information on a single computer could be comparable to the dimensions on another computer. Even the processing and storage power the all products are equal. Thus there’s no computer around the network that’s greater in value compared to other computer. And so the name peer to see network.
The 2nd kind of systems based on the above classification may be the client-server network. Within this type, the problem differs for the reason that not every computers are equal in value. At the very least, there’s one computer (that’s known as the server) which has much processing power and storage power. And so the information is stored with that computer to become shared over the network. Every computer that requires some data that’s shared over the network can children the server only. It is because all computers apart from the server tight on sizes of memory as well as processor power.
