What is circuit and packet switching and what is the different between them?
First: Multiplexing is defined as the sending of multiple signals over one single communications channel at the same time. For example, let’s say you have a T1 and you need to break that 1.544 Mbps of bandwidth down to a smaller amount because a company only needs half of that bandwidth. The company orders only a Fractional T1. What about the rest of that bandwidth, is it wasted? Of course not, not with Multiplexing. As a service provider, you can designate half of the bandwidth to company A and then the rest to company B who ordered the rest of it. Data is sent along the whole T1 and no bandwidth is wasted. The technology of multiplexing is used in many ways to conserve bandwidth. LANs on buildings use a network meduim that is shared. The cable that is used only takes one system at a time, and the systems should take turns using the LAN. This setup is called a base-band network. The information that the system broadcast is broken up in units and are called packets. When an email messa
