Types of network

This is all about types of network where you guys can easily understand about networks system in computer.

1. Types of Computer Network To- mrs. Kavita Singh.

2. Network; A network consists of multiple devices that communicate with one another. It can be as small as two computers or as large as billions of devices. While a traditional network is comprised of desktop computers, modern networks may include laptops, tablets, smartphones, televisions, gaming consoles, smart appliances, and other electronics.

3. Advantages and disadvantages of networks; Advantages; Sharing devices such as printers saves money.
Site (software) licences are likely to be cheaper than buying several standalone licences.
Files can easily be shared between users.
Network users can communicate by email and instant messenger. Data is easy to backup as all the data is stored on the file server. Disadvantages; Purchasing the network cabling and file servers can be expensive.
Managing a large network is complicated, requires training and a network manager usually needs to be employed.
Viruses can spread to other computers throughout a computer network.
There is a danger of hacking, particularly with wide area networks. Security procedures are needed to prevent such abuse, eg a firewall.

4. Different types of network; LAN; [Local Area Network]
PAN; [Personal Area Network]
MAN; [Metropolitan Area Network]
WAN; [Wide Area Network] A network is defined as a group of two or more computer systems linked together.
There are many types of computer networks, the common types of area networks including those;

5. Local Area Network [LAN]; Local Area Network is a group of computers connected to each other in a small area such as building, office. LAN is used for connecting two or more personal computers through a communication medium such as twisted pair, coaxial cable, etc. It is less costly as it is built with inexpensive hardware such as hubs, network adapters, and ethernet cables. The data is transferred at an extremely faster rate in Local Area Network.

6. Local Area Network [LAN];

7. Personal Area Network [PAN]; Personal Area Network is a network arranged within an individual person, typically within a range of 10 meters.
Personal Area Network is used for connecting the computer devices of personal use is known as Personal Area Network. Personal computer devices that are used to develop the personal area network are the laptop, mobile phones, media player and play stations.

8. Personal Area Network [PAN];

9. Metropolitan Area Network [MAN]; A metropolitan area network is a network that covers a larger geographic area by interconnecting a different LAN to form a larger network.
Government agencies use MAN to connect to the citizens and private industries. In MAN, various LANs are connected to each other through a telephone exchange line. The most widely used protocols in MAN are RS-232, Frame Relay, ATM, ISDN, OC-3, ADSL, etc. It has a higher range than Local Area Network(LAN).

10. Metropolitan Area Network [MAN];

11. Wide Area Network [WAN]; A Wide Area Network is a network that extends over a large geographical area such as states or countries.
A Wide Area Network is quite bigger network than the LAN. A Wide Area Network is not limited to a single location, but it spans over a large geographical area through a telephone line, fibre optic cable or satellite links. A Wide Area Network is widely used in the field of Business, government, and education. Examples Of wide area network- Mobile Broadband,Private network,Last mile.
