What is a computer network? This is not a question you often hear, but it is important nonetheless. Without a computer network, the network would not be as efficient as it is today, so we decided to set the network for beginners and different marang-ranks. Not only that, in this article we will discuss the benefits of networking. There are no real problems, so we can’t even go there.

 

What is a computer network?

A network is a group of computer systems that are connected to share devices and communicate. In addition, a network is also a collection of devices and computers that are interconnected by media portable and communication devices.

 

We’ll talk about download issues in another article, so keep that in mind soon.

Network utilities

Speed ​​of communication

Distribute shared hardware

Distribute Data and Dist

1] Fast communication

Because of networks, people can easily connect with each other through email, messaging tools, chat rooms, social media, websites like WebSite, online video calls and many more if one network becomes affordable. By the way, not all of these two tools will work anymore.

 

2] Non-connected hardware

If some hardware is connected to the network, these devices will be very easy to share with anyone who has access to the network. For example, database or printer files are very common on the network, and are called network resources.

 

3] Distribute Data and Dist

This is the problem; if you are an authorized user, you should have no problem accessing the data and information stored on the network. Companies like Microsoft, among others, will have large databases of consumer information, all of which are open to employees with the appropriate authority.

 

1] Area Network (LAN)

 

What we have here is a network connecting computers and devices in a small area. For example, a LAN is usually located inside a building. Of course, many local area networks can be connected within a building.

 

2) Wireless LAN (WLAN)

It relies on a router connected to the internet, which in turn provides a wireless connection to supported devices. The network is now in your home.

3] Metropolitan Area Network (MAN)

 

Well, then one is about connecting to local networks around cities. Because of the distance, the connection of these networks to create MAN is made by transmission technology, several. Coaxial and fiber are probably the most common for everything else in terms of cost.

4] Wide Area Network (WAN)

 

From what we can deduce, WAN is similar to MAN, with the difference being the speed. Large network, geographic LAN or WAN or combined with wireless technology, mostly satellites.

 

5] Private Area Network (PAN)

Just by name, you need to get an idea of ​​what this website is all about. It is a network that uses wireless cables and technology to connect computers and devices to a personal site.

 

6] Campus Area Network (CAN)

It is usually found in any university or company that has a headquarters such as a campus. It is larger than normal LAN, but at the same time smaller than MAN.

 

7] Storage area network (SAN)

This one is really simple. The storage devices are linked to each other using a high-speed connection.

 

Intranet

An intranet is a collection of networks that are under the control of an administrative entity. Administrative entities restrict the use of the intranet to their authorized users. Typically, an intranet is the internal LAN of an organization. Large intranets typically have at least one web server to provide users with organizational information. The intranet is also behind the router on the local area network.

Extranet

An extranet is a network that is also under the administrative control of a single organization, but which supports a limited connection to a specific external network. For example, an organization may provide access to certain aspects of its intranet to share data with its business partners or customers. These other entities are not necessarily trusted from a security point of view. Network connection to an extranet is often, but not always, implemented using WAN technology.

 

Darknet

A darknet is an overlay network, typically running on the Internet, that can only be accessed through specialized software. A darknet is an anonymous network in which connections are made only between trusted peers, sometimes referred to as “friends” (F2F) [21], using non-standard protocols and ports.

 

Darknets differ from other distributed peer-to-peer networks in that the exchange is anonymous (i.e., IP addresses are not shared publicly) and therefore users can communicate with little fear of government or corporate interference. .
