Computer Network: A Complete Information

A computer network is a system that allows computers, servers, printers, and other computing devices to interact and share resources. These networks can be as simple as linking two devices or as big as global infrastructures like the Internet.

What is a computer network?

A network is a group of computers connected in some fashion in order to share resources. a group of computers in a network would provide greater storage capacity and processing power than that by stand- along independent

Types of Computer Network:

• PAN ( Personal Area Network)
• LAN (Local Area Network)
• MAN (Metropolitan Area Network
• CAN (Campus Area Network)
• WAN (Wide Area Network)

Personal Area Network (PAN)

Definition: A PAN is a type of small-scale network that is intended to link devices in a relatively specific region, usually the vicinity of a single person.

Range: Approximately 1 to 100 meters.

Usage: Connecting personal devices such as smartphones, tablets, laptops, and wearables.

Example: Connecting a smartphone to a laptop via Bluetooth for file transfer.

Local Area Network (LAN)

Definition: Within a limited geographic region, such as a house, business, or college, a LAN links computers and other devices. LAN offers high seed communicatio of data rates of 4 to 16 megabits per second (Mbps).

Range: Up to 2 kilometers.

Usage: Makes it easier for devices in a small area to communicate and share resources.

Example: An office network where employees share files and access shared printers.​

Campus Area Network (CAN)

Definition: Multiple LANs within a given geographic region, such a company or university campus, are connected by a CAN.

Range: Typically between 1 to 5 kilometers.​

Usage: permits communication and resource sharing across several campus buildings or divisions.

Example: Connecting the networks of different departments within a university.​

Metropolitan Area Network (MAN)

Definition: A MAN, which usually spans a city or a sizable campus, is smaller than a WAN but covers a wider geographic region than a LAN. MANs are usually owned by large organizations to interconnected its various branches across a city. the computers connected in this type of network are mostly through wireless connection.

Range: Up to 50 kilometers.​

Usage: Provides high-speed data transmission and internet access by joining many LANs in a city.

Example: A city-wide Wi-Fi network providing internet access to residents and businesses

Wide Area Network (WAN)

Definition: Large geographic regions, like cities, nations, or continents, can be connected via a wide area network (WAN). They can also be connected through leased lines or satellites. These networks are mostly formed by large organization whose offices are spread across the country or continent . The internet are is one of the largest WAN

Range: Extends beyond 100 kilometers, potentially covering global distances.

Usage: Allows for global connection by facilitating data interchange and long-distance communication between LANs and MANs.

Example: The Internet, which connects millions of networks worldwide.
