Cards in this deck (7)
- 1network classification and topologythe flash will cover the following
classifications - LANs WANs PANs and VPNs
topologies - bus star ring mesh - 2LANA LAN is a network of computers which are connected together in a limited area, usually the same building or a couple of nearby buildings.
LAN's are usually high speed and they make use of connected peripherals such as printers. - 3WANsA wide area network or WAN is a computer network that joins computers together over long distances.
Computers on a WAN can be joined using the public telephone system, fibre optic cables, satellites or other means.
- 4PANsA personal area network (PAN) is the interconnection of information technology devices within the range of an individual person, typically within a range of 10 meters. For example, a person traveling with a laptop, a personal digital assistant (PDA), and a portable printer could interconnect them without having to plug anything in, using some form of wireless technology. Typically, this kind of personal area network could also be interconnected without wires to the Internet or other networks.
- 5VPNvirtual private network, is a network that is constructed by using public wires — usually the Internet — to connect to a private network, such as a company's internal network. There are a number of systems that enable you to create networks using the Internet as the medium for transporting data.
- 6star topologylayout structure : computers are organised into a star shape structure with normally a switch or hub in the middle to send and receive data .each computer is connected via fib-re optic cable .
benefits : if one of the cables connected to the computer breaks , the other terminals will into be affected . speed . topology is fast - 7bus topology
