A network is a collection of computers and devices connected together , often wirelessly, via communications devices and transmission media. When a computer connects to a network, it is online.
Networks allow computers to share resources, such as hardware, software,data and information. Sharing resources save time and money . In many networks , one or more computers act as server. The server controls access to the resources on a network. The others computer on the network, each called a client or workstation,request resources from the server (Figure1-6). The major differences between the server and client computers are that the server ordinarily has more power, more storage space,and expanded communications capabilities.
Many homes and most businesses and schools network their computers and devices. Most allow users to connect their computers wirelessly to the network. Home networks usually are small existing within a single structure. Business and school networks can be small , such as in a room or building ,or widepread, connecting computers across a city, country , or the globe. The worlds largest computer network is the internet.
