Understanding computer networks, complete with all types and differences

KOMPAS.com Some users who operate computers are usually familiar with the term LAN, MAN, or WAN. The term is used to refer to a type of computer network.

A single computer can be connected to several other computers or gadgets simultaneously over a network or network. After that, users can interact with many devices through a computer network.

One example that can be found from using a computer network is running an Internet cafe. Internet access on multiple client computers in an Internet café can be managed centrally via the responsible computer.

For example, settings for limiting Internet access time, download speed, restricting access to certain website pages, etc.

Without a computer network, such a central arrangement would not be possible. If you want to understand more about what is meant by a computer network, take a look at the explanation below.

A computer network is a system that connects many computers to share information (data) and resources. Computers and other connected devices will allow users to communicate more easily.

To create a network, many computers are connected to other devices using wired or wireless media.

Regardless of using hardware In this case, creating a computer network generally needs to install software or software software emphasis. Programming Used to discover devices on the network.

In simple terms, in a computer network, it usually consists of a server computer serving as a control center and a host computer as a place for users to work.

The simplest function of a computer network is to facilitate the division of the workload on the machine to run the program. In addition, the next function of computer networks is resource saving.

For example, with a computer network, many computers can print documents or files printing press via one device printer same, as stated GeeksforGeeks.

The types of computer networks often used are LAN, MAN, and WAN, as mentioned above. In addition, there are actually many other types of computers that are also used often, but you may not be very familiar with them.

Each type of computer network is different in general, according to the coverage area, connected devices, etc. So, what types of computer networks are they commonly used? Here is the explanation.

1. LAN

The first type of computer network is LAN (Local Area Network). LAN is a network that connects devices that are usually close together and uses cables as the main channel.

A LAN is typically used to connect several devices in a single home, or several computers that are connected by cable but still under one roof.

LAN is also implemented in many Internet cafes that connect many computers to one server, in the office room to connect several devices to one computer, servers, to printerand so on

2. The man

Metropolitan Area Network or MAN, as the name suggests, is a network used to connect different computers or devices within a city area.

A network with greater reach than a LAN can be used to connect computers in an organization to another within an administrative area.

3. WAN

A wide area network or WAN is a type of computer network that connects many devices, computers, or different types of networks (such as LAN and WLAN), within a fairly long range, even between countries.

With WAN, data on computers located in Indonesia, for example, can be easily and quickly transferred to computers in other countries, for example to the United States (US).

One easy example of implementing a WAN is the commonly used Internet so far, where the WAN will connect the device to a computer or server in another country.

4. PAN

A personal area network (PAN) is a type of computer network that usually connects various personal electronic equipment operated by the same person.

One simple example of using PAN is connecting devices printer to a computer or connect a computer with an extension Loudspeaker bluetooth.


Wireless Local Area Network (WLAN) WLAN is practically the same as LAN, but this type of network does not require cables to connect multiple devices.

With wireless technology such as WiFi, WLAN has the same function as LAN, so it can be used to connect computers and servers, printeretc. within a small scale.

An example of using WLAN is connecting several devices from a number of homes in a small area, or in one complex block to one WiFi network.

It is worth noting that the devices that wish to take advantage of WLANs must be equipped with WiFi technology support.

6. Can

A campus/company area network (CAN) is a network that connects many devices and computers in an educational institution such as schools, campuses, universities, institutes, etc.

CAN can also be used to connect multiple devices in a single multi-room corporate building.

For the school segment, the same CAN is usually used to simplify the administrative and academic processes of an educational institution, such as grade processing, student performance entry, etc.

7. SAN

A storage area network (SAN) is a network that connects computers to a number of high-capacity storage media on a server.

A device can access this SAN, and also retrieve data on it if it is connected to a server that is a storage media bridge.

8. Poland

POLAN (Passive Optical Local Area Network) is used as an alternative to LAN. However, instead of using regular cabling, POLAN uses fiber optic cabling to simplify the transfer process between devices.

The fiber-optic cable itself is known to have a fast enough performance to transfer data from one device to another.

A POLAN is usually used to connect optical fibers to routers, so that the Internet can later be routed to surrounding devices via WLAN.

9. EPN

An Enterprise Private Network (EPN) is typically used to connect many devices, storage, computers, etc. in one large company.

Of course, EPNs are used in terms of security, so EPNs are commonly used by companies that store many important data, such as personal user data.

Examples of using an EPN would be connecting subsidiary company networks to the main office, transferring data from buildings on campus to other buildings without using the internet, etc.

10. VPN

A Virtual Private Network (VPN) is a network that can be used to make users’ online activities more secure and untraceable.

The reason is that a VPN allows a user’s internet connection to connect to a private network owned by a company or server.

From there, the Internet connection or data sent by the user will be redirected to the server or computer you want to connect to, so that the data appears to be from the organization, even though it was sent by the user.

An example of a VPN is to use a VPN service, such as, NordVPN, ExpressVPN, etc. to access various foreign websites or website forbidden banned.
