- 2. Definition A network canbe defined as two or more computers connected together in such a way that they can share resources. OR A network is simply a collection of computers or other hardware devices that are connected together, either physically or logically, using special hardware and software, to allow them to exchange information and cooperate. Networking is the term that describes the processes involved in designing, implementing, upgrading, managing and otherwise working with networks and network technologies. 2

- 6. Computer network isclassified into 3 major types 1. Local area network (LAN) 2. Wide area network(WAN) 3. Metropolitan Area Network (MAN) 6
- 7. Local area network(LAN) A group of devices connected to one another in a single physical location, such as a building, office, or home, is known as a local area network (LAN). A LAN can range in size from a tiny, single-user home network to a big, enterprise network with thousands of users and devices in an office or school. In order to link devices to internal servers, web servers, and other LANs via wide area networks, a LAN is made up of cables, access points, switches, routers, and other components. 7
- 8. Wide area network(WAN) Awide area network, or WAN for short, is a sizable information network unconnected to a specific area. Through a WAN provider, WANs can enable communication, information sharing, and much more between devices all over the world. The largest and most well-known example of a WAN is the Internet. WANs are used to connect LANs and other types of networks together, so that users and computers in one location can communicate with users and computers in other location. 8
- 9. Metropolitan Area Network(MAN) A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network 9
