Knowledge of Computer Network and Types of Network: PAN,LAN,WAN,MAN. ..

Procedure. A computer network is a connection between two or more network devices, like computers, routers, and switches, to share network resources. The establishment of a computer network depends on the requirements of the communication channel, i.e., the network can be wired or wireless. Next, let’s look into the types of networks available..

Types of Networks. According to the communication requirements, multiple types of network connections are available. The most basic type of network classification depends on the network's geographical coverage. Below mentioned are different types of networks: PAN (Personal Area Network) LAN (Local Area Network) MAN (Metropolitan Area Network) WAN (Wide Area Network).

Personal Area Network (PAN). Personal Area Network (PAN):-personal area network is the computer network that connects computers/devices within the range of an individual person. As PAN provides a network range within a person’s range typically within a range of 10 meters(33 feet) it is called a Personal Area Network. A Personal Area Network typically involves a computer, phone, tablet, printer, PDA (Personal Digital Assistant) and other and other entertainment devices like speakers, video game consoles, etc. Thomas Zimmerman and other researchers at M.I.T.’s Media Lab first developed the concept of PAN. It is very useful in the home, offices, and small network areas due to its high performance in terms of flexibility and efficiency..

Local Area Network (LAN). The Local Area Network (LAN) is designed to connect multiple network devices and systems within a limited geographical distance. The devices are connected using multiple protocols for properly and efficiently exchanging data and services..

Attributes of LAN Network:. The data transmit speed in the LAN network is relatively higher than the other network types, MAN and WAN. LAN uses private network addresses for network connectivity for data and service exchange, and it uses cable for network connection, decreasing error and maintaining data security..

Advantages and Disadvantages of LAN Network. Advantages Transmission of data and services is relatively higher than other network connections. The Network Server acts as a central unit for the whole network. . Disadvantages Need constant administration of experienced engineers for functioning. Probability of leak of sensitive data by LAN administration..

Metropolitan Area Network (MAN). [image] MAN Network.

METROPOLITAN AREA NETWORK(MAN). Attributes of MAN Network: · Network covers an entire town area or a portion of a city. · Data transmission speed is relatively high due to the installation of optical cables and wired connections..

METROPOLITAN AREA NETWORK(MAN). Advantages and Disadvantages of MAN Network: Advantages Provides Full-Duplex data transmission in the network channel for devices. Disadvantages High probability of attack from hackers and cybercriminals due to large networks..
