The Bus Network essays The world revolves around technology. Everywhere we go we are affected either directly or indirectly by technology. In fact, almost everything that surrounds us is a product of technology. Cell phones, beepers, television, radio; these are just a few basic examples of technological advancement in our human history. Of the many remarkable achievements of technology, there is one that stands out on all of them: Computers.

WAN uses devices such as telepho ne networks, satellite dishes, or radio waves to span a larger geographic area than can be covered by a LAN. A MAN is a data network intended to serve an area the size of a large city. An Enterprise Network can either be a LAN, WAN, or MAN, however, an Enterprise Network is restricted to one organization. Now that we know the kinds of computer networks, have we ever wondered how these networks are connected to one another? Are these computers just plugged-in together by some kind of wire and then they ...
