Routers and modems are an essential part of networking technology. Computer network technology permits institutions and organizations to send information digitally with the assistance of a data system. When information transmission should be possible among one or two computers utilizing a medium of network communication such as cables or wires, then, at that point, it is called a computer network. At the same time, it is said to be a mobile network when the information is sent between two mobile devices via wires.

On the contrary, at the point when the data is communicated between mobile phones and PCs, it is known as a device network. All this data transmission is possible due to the network technology that allows the exchange of data among various devices in small and large amounts of information. This guide will help you learn every important detail related to network technology.

What is Network Technology?

The technology system is utilised to exchange data among small and large information systems. Schools and businesses mainly utilise this system. The network installation includes configuration and troubleshooting that the network technicians know, which can be utilised to send digital information like audio, information, and video.

documents. Through networking, clients can send messages and documents through email or different channels because of the association’s necessity.

The development of a network includes assessing a company’s organizational and educational needs as well as the costs of equipment, training, installation, security, and account management. When a network is established, the technicians are responsible for the network activity by offering technical help to the organization and its employees.

Different types of Network Technology

On the basis of transmission and scale, network technology can be differentiated. With the utilization of this technology, data transmission, too as an exchange, should be possible.

Network technology based on Transmission

The Transmission of network technology could be done based on two concepts as Point-to-point and multipoint.

1. Point to Point

When in point-to-point, when the nodes that send and receive are associated straightforwardly, then information transmission is possible with a guided medium, which is currently utilised for the wired network, and an unguided medium, which is mainly utilised for the wireless network.

2. Multipoint

In the multipoint case, some of the nodes are associated straightforwardly with the assistance of a common medium in a linear way. Multipoint transmission works at either of these two connections in the same way that time-sharing does, but it is always spatially shared. In the initial connection, each node is available with a different time slot to converse. However, in the subsequent connection, the interaction among the nodes should be possible simultaneously.

Network Technology from a Scale point of view

Because of the scale, the network technology should be possible by utilizing ideas like LAN, MAN, WAN, PAN, and VPN.

1. LAN (Local Area Network)

LAN is also called the IEEE 802 network, and this network utilises devices such as laptops, PCs, and mobile phones in a small range that goes from 100m to 10km. The network’s properties mainly rely upon its clients’ speed, range, and error rate.

The essential components of LAN incorporate the following;

  • Peripheral devices like printers, scanners, and so on.
  • A HUB, or the centre of a network, can be responsible for drawing in the signals. It is shrewd enough to communicate the information packets from the source to the recipient.
  • Due to their high transfer speed, cables such as twisted pairs, optical fiber, and coaxial cables are utilised as key cables.
  • Nodes/PC/computer/Host/server/workstation

2. MAN (Metropolitan Area Network)

Metropolitan area networks consist of numerous LANs that are further connected together through a networking device known as Bridge, and it shapes a MAN (metropolitan area network).

3. WAN (Wide Area Network)

A WAN is a network where various WANs are joined together through a networking device known as a route to make it a WAN (wide region network).

To be specific, there are two kinds of WANs: public and private.

  • Public WAN: In this public WAN, it is maintained through government divisions.
  • Private WAN: This type of WAN is extended by the divisions of the US Military’s Defense wing known as ARPANET.
WAN Elements:
  • The bridge, router, and gateway are known to be the key components of the WAN.
  • The Bridge is a device that helps to create a link between related or different LANs.
  • The router is a device that helps interface related or with different networks.
  • A gateway is one type of device used to link networks by utilising different models. For example, the link between a 4G network cell phone connection and a landline device with a 2G connection can be established by utilising this gateway.

4. PAN (Personal Area Network)

A The Personal Area Network (PAN) is primarily a computer network that allows the connection of nearby computers. These networks can be wired, such as USB or FireWire. These networks typically cover a few meters. Wireless consoles, headsets, printers, standardised code scanners, remote mice, and gaming consoles are usually the best examples of this. These networks are usually used primarily for individual purposes.

5. VPN (Virtual Private Network)

A VPN, also known as a virtual private network, is begun for all public network purposes to communicate data from sender to receiver. This network makes a solid, encrypted, and secure connection over a less-secure network like the public internet. The VPN uses the tunnelling protocol to encrypt and decrypt the data at the closures of the source and receiver.

Advantages and disadvantages of Network technology

Undoubtedly, network technology offers numerous benefits to this world. Despite that, it also comes with certain drawbacks. Let’s have a look at the advantages and disadvantages of network technology.


The advantages of network technology incorporate the following;

  • Network technology is incredibly adaptable.
  • It enhances the communication and availability of data.
  • Network technology also takes into account convenient resource sharing.
  • One can share and receive files handily.
  • Network technology is less expensive and offers enhanced storage capacity.


Network technology also comes with certain disadvantages as follows;

  • The absence of freedom and robustness
  • Network technology makes security difficult.
  • While browsing the network, the devices can get infected with viruses and malware.
  • It needs a proficient operator.

Network Technology FAQs

1. What is network technology?

The transmission of data from an extensive data system to some small information system is known as network technology.

2. What are the various types of networks?

There are three types of networks: LAN, MAN, and WAN.

3. What is the advantage of networking?
