A computer network is composed of end devices, network media, and intermediary devices connected together. The number of computers that can be connected depends on the type of network, which is classified by geographical size as a personal area network (PAN), local area network (LAN), campus area network (CAN), metropolitan area network (MAN), wide area network (WAN), wireless local area network (WLAN), or peer-to-peer network. In a client/server network, servers provide centralized services and resources to client devices, while in a peer-to-peer network all devices can act as both clients and servers sharing resources directly.

Illustration of a Computer Network
How many computers can we be able to connect to a network?
Types of Network According to Geographical Size PAN (Personal Area Network) LAN (Local Area Network) CAN (Campus Area Network) MAN (Metropolitan Area Network) WAN (Wide Area Network) WLAN (Wireless Local Area Network)
PAN (Personal Area Network) A personal area network (PAN) is a computer network for interconnecting electronic devices centered on an individual person's workspace. A PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs can be used for communication among the personal devices themselves, or for connecting to a higher level network and the Internet where one master device takes up the role as gateway. A PAN may be wireless or carried over wired interfaces such as USB.
LAN (Local Area Network) is a network in which computers are relatively close together, such as within the same office or building.
CAN (Campus Area Network) A campus area network (CAN) is made up of an interconnection of LANs within a limited geographical area. The networking equipment (switches, routers) and transmission media (optical fiber, copper plant, Cat5 cabling, etc.)
MAN (Metropolitan Area Network) is a network thats smaller than a typical WAN but larger than a LAN. Typically, a MAN connects two or more LANs that are within the same city but are far enough apart that the networks cant be connected using a simple cable or wireless connection.
WAN (Wide Area Network) is a network that spans a large geographic territory, such as an entire city or region, or even an entire country. WANs are typically used to connect two or more LANs that are relatively far apart.
Internet
WLAN (Wireless Local Area Network) a LAN based on WiFi wireless network technology
Intranet and Internet Specifications Intranet: An intranet is a private network that is contained within an enterprise. It may consist of many interlinked local area networks and also use leased lines in the wide area network. An intranet uses TCP/IP, HTTP, and other Internet protocols and in general looks like a private version of the Internet. With tunneling, companies can send private messages through the public network, using the public network with special encryption/decryption and other security safeguards to connect one part of their intranet to another. Internet: is a worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers).
Client and Server computer role in networking A network server is a computer designed to act as central repository and help in providing various resources like hardware access, disk space, printer access, etc,. to other computers in the network. A network server might not differ from a workstation in hardware, but the functionality it performs clearly differentiates it from other workstations. Network servers helps in simplifying the different tasks for system administrators including those centering around management. Any configuration or security updates can be applied to a network server instead of individually passing to different computers connected to the network.
Client and Server computer role in networking A Client is a piece of computer hardware or software that accesses a service made available by a server as part of the clientserver model of computer network Client computers normally request and receive information over the network client. Client computers also depends primarily on the central server for processing activities
Peer-to peer network A peer-to-peer network is a network where the computers act as both workstations and servers. great for small, simple, and inexpensive networks. In a strict peer-to-peer networking setup, every computer is an equal, a peer in the network. Each machine can have resources that are shared with any other machine. There is no assigned role for any particular device, and each of the devices usually runs similar software. Any device can and will send requests to any other
Client/Server Networking In this design, a small number of computers are designated as centralized servers and given the task of providing services to a larger number of user machines called clients
