TOPOLOGY COMPUTER NETWORK



Information needs at the present time is very important, as well as become a necessity as a means of communication and information retrieval, making those needs as a secondary need in everyday life.
With increasing demand, the increase also makes computers that are available but in time can be used for a form of shared usage.
For that initial thought is created in the early twentieth century, precisely in 1942 in the United BELL cooperation between research teams with the development of research teams from a renowned university in America, namely: HARVARD.
Research and development led to a result of an early use of the computers that the polynomial can be united in one network whose benefits can be felt collectively, but by setting a common center or network with: server, so comes the opinion of the unification of a single unit of this network with the term: a computer network topology, although at that time still in the benefits and limitations of its usefulness.
Computer network topology is a system of computers that deliberately gives a chance to share in terms of usability in terms of: network between computers or printers, communication or chat, and each can access the information in this case access to a browser that is widely available for can open the website.
Early access of a computer network is the formation of a central network called: server.
These stem network divides it by the division of services to several other units, commonly referred to as: the client.
But the division is not directly through a central server, but necessary liaison, namely, additional equipment such as hubs, routers or switches, which are used as intermediaries taupun divider network between these computers.
