10+ Functions and Benefits of Computer Networks in General, Complete!

If you run a computer, of course you know that a computer cannot run by itself. There are several components needed for a computer to run well. One of these components is a computer network. Computer networks allow humans to connect with each other without being limited by distance and time. Now, we live in a digital world where computer networks play an important role in helping our daily lives, such as working, studying, conducting online meetings, playing games, and much more.

So what is a computer network? What are the benefits and types of computer networks that can be known. The following is the definition, benefits and types of computer networks that you can look at.

A computer network itself is two or more computer devices that are interconnected with each other, which function to share data sources. Computer networks themselves can be private or public. If you are using a private network it usually requires a password to access it which can be obtained manually or directly by the user. Meanwhile, for public networks such as the internet, you can access them directly.

In fact, the concept of computer networks itself has existed since the 1940s in America, run by a research group from Harvard University led by professor Howard Aiken. Initially the idea arose while working on a task together, but without wasting much time, then a sequential process was created, until in the end the program could be run on several computers at once. It started from that time that computer networks emerged so that we can use them today and are able to provide various benefits for our daily activities.

1. Can exchange data easily

With computer networks such as the internet and others, it can make it easier for you to exchange data or documents easily. You can send and receive data via computer at any time using the internet.

2. To maintain data security

Apart from that, computer networks also have data protection, so that your or your company's important data or documents stored on your computer will be guaranteed safe.

3. Can facilitate communication

Apart from making it easier to exchange data, the existence of a computer network can also make it easier to carry out optimal long-distance communications.

4. Can convey information quickly

You can easily access the information currently available with a computer network. You can also access this information anytime and anywhere without being limited by distance and time.

5. Can save costs

With a computer network, users don't need to bother printing important documents or files, users only need to save them to the computer and can easily exchange data via the internet so they don't need to spend money on printing files and so on.

6. Can help maintain information up-to-date

The existence of a computer network can also make the information received every day up-to-date. Because it can be accessed at any time, and the process of sending information is also very easy and fast so it doesn't take a long time.

1. PAN (Personal Area Network)

Usually this network is used in smaller areas and is mostly used only for internet purposes, printers, and several purposes that do not require large resources. This network can also usually be found in homes and offices.

2. LAN (Local Area Network)

This network is usually used to connect network devices whose coverage is relatively small. Not only that, LAN also provides wireless network technology using WiFi, commonly known as WLAN (Wireless Local Area Network). So the use of this network is very suitable for use in homes, schools, campuses, buildings and offices.

3. CAN (Campus Area Network)

CAN networks can actually be said to be almost the same as MAN networks, but this network tends to be more limited when used in campus or academic environments. Therefore, this network is usually only used for certain purposes such as in laboratories, class updates, and so on.

4. MAN (Metropolitan Area Network)

Man or Metropolitan Area Network can be said to be a combination of several LANs. MAN itself can also reach around 10 to 50 km, so it is very suitable for building networks in office areas located in one city or region at once.

5. WAN (Wide Area Network)

Meanwhile, WAN is a computer network that can cover a large area. Examples include computer networks between cities or regions, or even between countries at once.

6. VPN (Virtual Private Network)

VPN itself is a computer network that can provide a more secure internet connection. VPN can also create a secure path for data exchange. Currently, many platforms have emerged that provide VPN services for free.

7. Internet

And the most commonly heard is the internet. As is known, the internet is the largest network that can cover all countries at once. So that anyone can now easily access news and information quickly and easily, even from different countries.

Closing,

With the existence of computer networks, we can now experience various kinds of convenience, especially in the fields of communication and information. Information from various countries can be easily accessed, apart from that, communication can also be easily done via the internet in various ways such as: video calls, telephone calls, email, messenger, and many more. The process of exchanging data or documents can also be done easily and quickly with a computer network.

What are the negative impacts of computer networks?

Among the various benefits and conveniences offered by computer networks, of course there are negative impacts from using these computer networks, for example, it requires a computer that can act as a server, and the continuity of the network also depends on the server. So if the server experiences a problem, the entire network will automatically be disrupted.

What are the benefits of using computer networks for companies?

There are many, for example, making it easier to exchange information, saving costs and time, and facilitating internal company affairs.

Mention how many types of computer network topologies there are?

There are 5 types, starting from BUS Topology, MESH Topology, RING Topology, STAR Topology, and Tree Topology.
