The word network can be used to describe a very large and complicated set of equipment.
A network consists of two or more computers that are linked in order to share resources (such as printers and CDs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.
Two very common types of networks include LAN & WAN.
A Local Area Network (LAN) is a network that covers a relatively small area. It is generally limited to a geographic area such as a writing lab, campus, or building.
Computers connected to a network are categorized as servers or workstations. Servers are generally not used by humans directly, but rather run continuously to provide "services" to the other computers (and their human users) on the network. Services provided can include printing and faxing, software hosting, file storage and sharing, messaging, data storage and retrieval, complete access control (security) for the network's resources, and many others.
Workstations are called so because they typically do have a human user who interacts with the network through them. Workstations were traditionally considered a desktop, consisting of a computer, keyboard, display, and mouse, or a laptop, with integrated keyboard, display, and touchpad. With the advent of the tablet computer, and the touch screen devices such as iPad and iPhone, our definition of workstation is quickly evolving to include those devices, because of their ability to interact with the network and utilize network services.
On a single LAN, computers and servers may be connected by cables or wirelessly. Wireless access to a wired network is possible due to wireless access points (WAPs). These WAP devices provide a bridge between computers and networks.
Anyway servers are normally connected by cables to the network, because the cable connections remain the fastest. Workstations which are stationary (desktops) are also usually connected by a cable to the network, although the cost of wireless adapters has dropped to the point that, when installing workstations in an existing facility with inadequate wiring, it can be easier and less expensive to use wireless for a desktop.
Wide Area Network. Wide Area Networks (WANs) connect networks in larger geographic areas, such as a country.
