Understanding 11 Types of Internet Networks and Their Functions

Currently, the internet has become an extremely important source of data and is used by almost everyone around the world. The internet network connects millions of computers, websites, and servers. In using the internet, reliable network monitoring is required. Get to know what the internet network is and its various types below!

What is the Internet Network?

The Internet is a global network that connects computers and other devices around the world, allowing its users to share information, communicate, and access resources. The Internet uses a common language to communicate between devices and high-speed data communication pathways to allow users to access information from anywhere in the world.

Type of Internet Network

Since it was first discovered on January 1, 1983, the internet has developed very rapidly. Now there are many computer networks and the internet that are used according to individual needs. Here are the various types:

1. Local Area Network (LAN)

Local Area Network or LAN is the most commonly used type of network. This network allows users to connect over short distances in public areas. Once connected, users will have access to the same resources.

For example, LAN users can use this network when connecting a laptop to the internet at home or in the office and printing documents from a printer that is on the same network. LAN is very easy to use.

2. Personal Area Network (PAN)

It is a personal area network, a small-scale PAN centered around one person or one device. PAN only connects a few devices in a small local area. PAN usually operates from one or two main devices. For example, if we use the Bluetooth function on our phone to share photos with nearby devices, it means we are using PAN.

3. Wireless Local Area Network (WLAN)

Wireless local area networks operate similarly to LANs because they transmit data over a small area. Devices that use WLAN rarely use wired connections. WLAN is relatively weaker and less secure compared to other types of networks on this list, but it is one of the most flexible for use with various devices in different locations.

An example of its use is in a home that uses a baby monitor. This monitor can be connected to WLAN. The purpose is to ensure that the device can continue to operate wherever the baby sleeps.

4. Campus Area Network (CAN)

As the name suggests, a campus area network is designed for use in educational environments, such as campuses and schools. Although each department in a school or faculty in a university has its own LAN, all the LANs used can be connected through a CAN.

This network combines several independent networks into a single integrated unit. For example, the Faculty of Nursing and the Faculty of Engineering can communicate directly with each other by utilizing CAN.

5. Metropolitan Area Network (MAN)

A metropolitan area network is a network with a larger scale than a CAN, specifically of medium size. MAN is indeed a type of network that is expensive, but it can provide efficient connectivity between devices over a wide geographical range.For example, the city government can operate with a MAN if it has offices throughout the metropolitan area.

6. Wide Area Network (WAN)

A wide area network is a network with a broad range, not limited to geographical space. Companies can use WAN to provide a public network with extensive connectivity. For example, remote workers who use the internet to access information from their company can take advantage of WAN.

7. Storage Area Network (SAN)

A storage area network is a network that is typically used by companies to store a large amount of sensitive data. This network provides a way to centralize data on a non-local network that is separate from the main operational network.

One example of a Storage Area Network is when a team in a company stores customer information on a separate network to maintain high speed on the main network. Thus, the performance on the main network will not be disrupted.

8. Passive Optical Local Area Network (POLAN)

Passive Optical Local Area Networks are low-cost networks that can connect various locations to a central network. POLAN has the capability to connect multiple entities to a single information hub.

For example, if the district headquarters of the Ministry of Education needs to connect with every school in its district. The headquarters can use POLAN to connect with all the schools.

9. Enterprise Private Network (EPN)

A corporate private network is an exclusive network built and operated by businesses to share corporate resources at high speed. EPNs are usually uniquely designed for specific companies, ensuring their connections remain secure. For example, a high-security technology company might use an EPN to reduce the risk of data breaches.

10. Virtual Private Network (VPN)

A virtual private network is a private network available on the internet. This network functions similarly to an EPN because it provides a secure private connection. VPN usually does not require the same infrastructure as EPN. The general public and companies can use a VPN to ensure privacy and security while browsing the internet.

11. System Area Network (SAN)

A Storage Area Network (SAN) is a wide local area network that provides connections within a cluster. Various devices connected in a SAN operate as a single system. SAN is a type of network that has been newly developed. SAN operates at high speed.

System Area Network is usually used for enterprise computing systems, supercomputers, and server clusters. Its purpose is to store data, back up data, access data, and much more. With high bandwidth, its performance is also very high.

Uses of the Internet Network

The internet network has various uses that we might utilize every day. Here are some of its main functions:

• Communication: allows its users to connect with others from a distance easily, regardless of distance.
• Entertainment: providing access to a variety of entertainment options, ranging from music, movies, videos, and games.
• Education: providing access to various educational resources for school students, university students, and the general public.
• Non-cash transactions: allow users to conduct transactions online, without the need for cash.
• Social networks: allow users to connect with others who have similar interests.
• Job opportunities: creating various job opportunities in fields such as digital marketing, e-commerce, web development, and much more.
