Computer Networks: An Overview and Classification

When many computers are linked together in a network. They are able to communicate with one another and share files, programs, and other resources. The size of a network is one criterion that can be use to classify the many kinds of computer networks. Networking refers to the linking together of two or more independent computers for the purpose of sharing resources. Through a number of communication channels and protocols.

All the Borrower’s modems, transmission gear, exchange. And data processing devices are include in the Networking System. Technique of transferring information from a small to a big storage space. This innovation can be use in both commercial and academic settings. Network professionals may set up, configure, and troubleshoot the infrastructure necessary. To transmit digital information such as sound, data, and video files. Users can communicate and share information via the network. Using email or other channels as required by the business.

Various Forms of Networking

We may classify network technologies according to their capacity for transmission and expansion. The sharing and transfer of information is possible by this technological advancement. Also, there are the parts of computer networks.

Engineering for long-distance data transmission

Transmission-based network technology employs either a point-to-point or a multi point architecture. Depending on the specific application.

To the Point

When the sender and the receiver (nodes) are in proximity to one another. Data can be sent between them using an unsupervised channel for wireless networks. Or a guided channel for wired networks in a point-to-point network. Below is a diagram illustrating the point-to-point networking technique.


In multi-point, numerous points are linked together in a straight line using a single medium. Take a look at the diagram below to see how multi point networks function.

It’s common for this mode of transmission to be use with either a time-sharing or a space-sharing connection. Take a deep look at https://perfectpcserver.com/ to gather more details about the multi point networks function. In the first connection, each node can only communicate during its allotted time slot. While in the second connection, all nodes can talk to each other at once.

Innovative tools for large-scale networks

Using LAN, MAN, WAN, PAN, and VPN ideas, it is feasible to create scalable network technologies.

Acronym for “Local Area Network”

IEEE 802, often known as a LAN. Links electronic devices within a limited area (typically between 100 meters and 10 kilometers). To share data and communicate with one another. The network’s features are mostly impact by factors like number of users. Transfer rate, coverage area, and error rate.

In a nutshell, a LAN consists of the following:

  • The HUB, or “heart” of a network, may be responsible for receiving data from nodes such as printers and scanners. It can send data packets from sender to recipient.
  • High-bandwidth applications necessitate the usage of backbone cables. Such twisted pairs, optical fiber, and coaxial cable.
  • Node, personal computer, computer, host, server, workstation, NIC.

MAN is an abbreviation for “Metropolitan Area Network”.

A bridge is a networking device that connects many local area networks together to form a wide area network.

Wide Area Network

As a service, routing connects many WAN’s to form a larger network. A visual representation of how WAN technology operates in a network environment is shown below.

More so, WAN provides two distinct sorts of variety:

  • Public wide area networks are managed by government bodies (WAN’s).
  • Defense, or ARPANET as it is most often known inside the United States Armed Forces. Is growing private wide area networks.

Different parts of a WAN are:

The wide area network (WAN) consists of three parts: a bridge, a router, and a gateway.

  • To connect two or more separate local area networks, you need a bridge.
  • A router is a device that helps to connect many independent networks.
  • A gateway is a piece of hardware used to connect two networks of dissimilar design. For instance, a 4G mobile device and a 2G landline device can talk to one another thanks to this gateway.

Personal Area Connection (PAN)

A PAN is a kind of computer network that provides for interaction. Between personal electronic devices in close physical proximity to one another. These connections might be done through cable (e.g., USB or FireWire) or wirelessly (via IR, UWB, or ZigBee). The average operating range of this network is on the order of a few meters. Many modern conveniences rely on wireless technology. Such as mice, gaming consoles, printers, barcode scanners, cellular phone headphones, and keyboards. As its name implies, this network is only for internal company usage.

Virtual Private Network (VPN)

A virtual private network (VPN) is a private network. That can be access via the internet and used to send and receive data securely. This network establishes an encrypted connection in place for a less secure network, such as the internet. Tunneling methods help to encrypt and decrypt the data at both the sender’s and receiver’s ends of this network.


There are several pluses to having a variety of network options. The first and maybe most important benefit is its flexibility. More information and communications may be shared over a greater variety of networks. Further, it facilitates cooperation by facilitating the sharing of resources. Sharing files with others is also easier now that we have networked systems. It is also cheaper and more efficient than alternatives. Another advantage is that storage space may be increase.


There are advantages to having many types of networks, but there are also limitations. To begin with, it’s not cheap, there are certain safety concerns, and you’ll need the help of a trained operator.

So, naturally, this is all about some kind of network or computer system. Connectivity technology allows for a number of devices to communicate and collaborate. Network types include everything from a hardwired office LAN to a wireless connection at home. From devices submerged in water to global satellite transmissions, and everything in between.

While this technology facilitates the quick and easy transfer of data. It is not without limitations that users must be aware of. Regular use of this technology has risks, and users might be aware of the dangers they face as a result.
