Information Technology. In certain depictions you can see lines connecting CPU's and a single switch. For example, how it should be addressed, transmitted, routed, and received. Networking trends that play a key role in IT include: One of the biggest advantages to this topology is that if a cable breaks or a computer on the network fails, the rest of the network will continue to work. By definition, information technology (IT) is the technology that involves the development, maintenance and use of computer systems, software, and networks for the processing and distribution of data. In a literal sense, information technology is a subset of information systems. They decided that the way the IP addresses are handed out would be to create a class for each of the different IP addresses. An IP address is a series of numbers separated by periods that are unique to each computing device that is connected to the Internet. A Static IP address is one that never changes so that people have a convenient and reliable way that remote computers can access. This make them suited for undersea cables such as the Transatlantic cable. Second, the internet layer connects independent networks that provide inter networking. The clouds you see in many pictures are used to portray the external networks connections between external and internal devices, without showing the details of the outside network. That switch may also be connected to a printer or fax machine and a router. It was also known as the Department of Defense model because it was funded by DARPA. Data bounces between each node to get to the machine where it needs to be. They are usually used by web sites, DNS servers, or network gateways. Networking utilizes devices such as switches, modems, routers, gateways, etc. Article excerpt. A network switch is a multi-port device that connects multiple computers together to create a network. If the central component stops working, the entire network and anything connected to it, will also stop working. Close. a point-to-point connection refers to a communications connection between two communication endpoints or nodes. These include but are not limited to: A wired network must contain some type of medium to transfer data over. Computers MUST connect to a network of any topology because of information sharing and communication. Other examples of point-to-point communications links are leased lines, microwave radio relay and two-way radio. These cables have a transmission range from 2 million to 10 billion bits per second. 3. Classified as one of the easiest "Star Based Networks" to add computers to a network.
