It may seem that geeks or tech-savvy nomads would find learning about the computer network and its connection system to be enjoyable, but that is not always the case. To understand the fundamentals of how computer networks operate, you don’t need to be an expert in computers.
I’ll describe computer networks and types of computer networks in this guide.
Let’s get started now if that seems like what you’re searching for.
What is Computer Network?
A computer network, as the name indicates, is a link between two or more computers that allows for electronic data transmission. The crucial role of a network system is to provide a coherent design that enables a range of information transmission channels.
The kind of network connection that the computer network offers to these machines for data connection also determines how the computer network functions and will be discussed in this article.
Types of Computer Network
1. Local Area Network (LAN):
A LAN is a collection of computers that are physically linked in a space, such as an office.
LAN refers to the connection of two or more computers over a communication means, such as a coaxial wire, etc. As a result, it is a less expensive choice since it just requires basic gear, such as Ethernet cables, network adapters, hubs, etc.
Additionally, LAN provides greater security, preventing outside meddling. In LAN connections, data is also exchanged at an incredibly quick pace.
2. Personal Area Network (PAN):
A PAN is an internal user-contained network. It is used to link personal use gadgets. A 30 foot area is covered by the personal area network. Personal area networks, such as those on computers, mobile phones, media players, or play stations, may be used to link the devices.
There are two kinds of personal area networks:
- Wired personal area networks, which can be built using a USB, and
- Wireless personal area networks, which can be built using wireless technologies like WiFi and Bluetooth.
3. Metropolitan Area Network (MAN):
By linking to other LANs to create a bigger network, metropolitan region networks may span a broad area.
Communication between banks in a city may be facilitated through MAN. It may be used to bookings for flights. In the military, it may also be utilised for communication. Additionally, it is offered by internet service providers (ISPs) operating across considerable distances. One ISP that has a metropolitan area network connection stretching across a significant geographic region and offers Xfinity Internet services to individuals in that area is Comcast Xfinity.
4. Wide Region Network (WAN):
A WAN is a network connection that spans a wide geographic area, such as many states or countries. Through phone lines, fibre optic cables, and satellite links, it is not restricted to any one nation but rather covers the whole region.
One kind of Wide Area Network is a mobile network connection, which is common in every area and nation.
In this form of network, devices are used to link two or more LAN or WAN computer networks. Additionally, a local addressing system known as internetworking is used to setup them.
It also describes a link between two or more government, commercial, industrial, or private computer networks. Internet Protocol is used in this kind of computer network.
An Internetwork is categorized in the following sub-types:-
Extranet: An internet-based communication network, such as the internet protocol or transmission control protocol. Information exchange takes place on an extranet, but only people with login access are allowed to utilise it. The lowest level of internetworking is an extranet, which falls under the MAN, WAN, etc. categories. The extranet cannot have a single LAN since it has to be connected to at least one outside network.
Intranet: Just like transmission control protocol and internet protocol, intranet is built on internet protocol. The intranet, on the other hand, is a property of the organization and is only accessible to its personnel. The exchange of resources and information among workers is made possible through an intranet. They may also utilize resources like teleconferences.
The bottom line is that LAN has several benefits over MAN and WAN, including dependability, high data transfer rates, and ease of management. MAN is used in this situation to link cities and vast regions since LAN cannot reach cities. Finally, a WAN connection is used to link the various nations.
So there you have it, data transfer between several devices uses various sorts of computer networks.
