A computer network connects two or more computers so they can share resources like printers and files. It can be wired or wireless. Based on geographic area, networks are classified as local area networks (LANs), metropolitan area networks (MANs), or wide area networks (WANs). LANs connect computers within a building or home. MANs connect buildings within a city. WANs connect across large distances from hundreds to thousands of miles, like the Internet. They allow sharing of expensive devices, easy file/data access from different locations, and remote work. However, they require maintenance and have security/connection issues.

- 3. A computer network is a group of interconnected computers . It 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. Lnked through cables, telephone lines, radio waves, satellites, or infrared light beams.
- 7. Depending upon the geographical area covered by a network, it is classified as:
- 9. A LAN is a network that is used for communicating among computer devices, usually within an office building or home. Is limited in size, typically spanning a few hundred meters Requires little wiring, typically a single cable ) LARGE AREA NETWORK
- 11. Users can communicate with each other very easily. Users can access their files from any workstations. When a new version comes out, it only has to be loaded onto the server Workstations can share peripheral devices like printers.
- 13. Area covered is limited Networks are difficult to set up and need to be maintained by skilled technicians. Costs for equipment and technology is very expensive WAN. Low bandwidth therefore it is easy to lose connection
- 15. It is a network that is utilized across multiple buildings Commonly used in school campuses or large companies with multiple building geography to a single metropolitan area Examples of MAN: cable TV network
- 18. • This type of connection can connect numerous locations together in one municipality. • MAN can cover a wider area than a LAN • By running a large network connectedness, information can be disseminated more widely, rapidly and significantly.
- 22. A Wide Area Network is a network spanning a large geographical area of around several hundred miles to across the globe The largest WAN in existence is the INTERNET. WANs often connect multiple smaller networks, such as local area networks (LANs) or metro area networks (MANs). It can be connected through cable, fiber or satellite.
- 25. Expensive things (such as printers or phone lines to the internet) can be shared Data can be better controlled when it's centralized and consolidated Share information/ files over a larger area It allows some business persons to work from home while still being able to access work interfaces.
- 27. allows business persons to work from home Need a good firewall to restrict outsiders requires network supervisors to maintain a network Security is a real issue
