A network is a series of nodes linked together by arcs. In computer terminology, the arcs are called links and the way the nodes are connected is called a topology.
In telecommunications, a network is any connection of two or more computers that enables them to communicate. Network nodes may include servers, routers, network printers, and satellites. Network links may include cables and wireless transmission devices. The phone network is the total infrastructure for transmitting phone messages. The Internet is the largest network on the planet. The way in which the nodes are connected is described by the network's topology
"Wired" and "Wireless" Networks
"Wired" networks are connected using wires (such as Ethernet cables). "Wireless" networks are connected using radio technology.
The advantages of "wired" networks over "wireless" ones include increased security and faster speeds. The advantages of "wireless" networks over "wired" ones include convenience.
The excessive use of radio technology brings the issue of radiation to mind. RF radiation burns skin tissue, and some studies claim it can cause cancer.[1] There are similar complaints with regard to cellular phones.
