Facilitating communications: Using a network, people can communicate efficiently and easily via e-mail, instant messaging, chat rooms, telephony, video telephone calls, and videoconferencing.
Sharing hardware: In a networked environment, each computer on a network can access and use hardware on the network. Suppose several personal computers on a network each require the use of a laser printer. If the personal computers and a laser printer are connected to a network, each user can then access the laser printer on the network, as they need it.
Sharing files, data, and information: In a network environment, any authorized user can access data and information stored on other computers on the network. The capability of providing access to data and information on shared storage devices is an important feature of many networks. Sharing software: Users connected to a network can access application programs on the network.
The ICT Network Classification:
The Network is classified into Wired Technology and Wireless Technology
Wired Technology: “It is very reliable and cheap. It is not affected by other wireless signals like portable/cellular phones, microwaves; etc.It has high life expectancy, high speed with Quality of Service.” (Erik Rodriguez, 2005 ).At the same time the length of wire runs limited, Can be affected by noise generated by machinery and magnetics, affected by moisture and other weather conditions.The wired Technology is of several type like Twisted paired wire, Coaxial Cable,Fiber Optic Cable.
