Companies, institutions and industries require a system that interconnects their Computers or information devices to build up fast and secure communication. Suppose you work in a large institution that has many departments and sections. Now, you need to collect electronic data in a computer of your department from any other department. For this, you need a network system that connects those computers. Internet Network Technology provides such systems. It is used for personal purpose. In this article, we are going to discuss the basic concepts of Computer Network Technology, different types of Networking and its advantages and disadvantages.

What is Network Technology in computer?
The Computer Network is a kind of technology that helps to interconnect the computers and other electronic devices of a company or institution to develop a fast and secure communication system. Using a computer network technology with an internet connection, an institution can transmit or exchange electronic data in different sections or departments or infrastructures via its computer system. Network administrators control this type of technology.
Computer internet networks, mobile internet networks, device networks, etc. are the applications of Network technologies.
- Computer networking is the system that exchanges data between computers.
- A Mobile network is a system that enables the exchange of data among mobiles.
- A Device network is a system that allows the exchange of data among any electronic devices like computers, mobiles, tablets, etc.
Examples of Network Technologies for Computers
Any system that provides an internet connection is an example of Network technology. Here are the most common examples of Computer network technologies –
- The Wi-Fi connection at home or hostel is an example of network technology
- The local area networking (LAN connection) in an institution or any working place is another example of computer networking.
- Artificial intelligence and Machine learning are also among the network technologies.
- Cloud network technology is another example.
Use of internet Networking in computer
Some of the examples that involve the usage of the internet are listed below.
- Sending a text message, audio file or any data using email, WhatsApp, etc. are examples of usage of network technologies.
- During transmitting data from one device to other devices we use network technologies.
- Submission of online application for any job or exam uses the network system. Yes, you need to use network technologies to apply for a network technology job in a network technology company. This sounds crazy? But, it is the fact!
Types of Network Technology for Computers
There are mainly two types of Internet Network technologies in Computers –
- Transmission-based network technologies
- Scale-based network technologies
Internet Networks based on transmission
One can set up a transmission networking system using two different concepts –
- Point-to-point concept
- Multi-point concept
Point-to-point concept of transmission Network Technologies
In the case of point-to-point networking, nodes in the network are connected directly. The data can be transmitted directly from one device to another. The transmission of data takes place via a guided medium for the wired network and via an unguided medium for the wireless network.
Multi-point concept of transmission Network Technologies
To transmit the data from one device to several devices we need to develop a network technology based on a multi-point concept. In this networking system, several nodes are connected linearly via a common medium.
Internet Networks based on scale
There are different types of internet networking based on scale. The main 4 types of networking are as followings –
- Personal Area Network (PAN)
- Local Area Network (LAN)
- Metropolitan Area Network (MAN)
- Wide Area Network (WAN)
Apart from these, Virtual Private Network (VPN), Campus Area Network (CAN), Storage Area Network (SAN), Enterprise Private Network (EPN), etc. are examples of scale-based internet networking.
Let’s have a brief description of these internet networks.
PAN stands for Personal Area Network. It is a computer networking system that connects electronic devices inside a very small area. PAN is used for personal purposes. It uses some low-powered devices like Bluetooth, USB, ZigBee, etc. to exchange data within a small range of distance (typically 10-15 meters).
The full form of LAN is Local Area Network. LAN is a computer internet network that connects computers and laptops inside a small area or local area like a department of any college or university, a building like a hostel or other resident, etc. The typical range of a LAN network is about 100 m to 10 km. LAN can be both wired and wireless. A wired LAN requires cables and ports or Ethernet to connect computers inside this range and most of the wireless LANs use Wi-Fi to connect the computers, laptops, tablets and smartphones in its range.
MAN stands for Metropolitan Area Network. Its name itself suggests the range of this network. MAN is a computer network that connects the computers and laptops inside a metropolitan area or any other geometrical area of the size of a Metropolitan. It is a bigger network than the LAN. MAN is the interconnection of LANs in a metropolitan area.
The full form of WAN is Wide Area Network. A WAN connects users via computers, laptops, smartphones, etc. across a wide geographic area. In WAN, a group of nodes is interconnected by telecommunication links that helps to exchange message and other data among the users. The Internet is an example of a WAN. All LANs and MANs are connected to WAN to provide connections among the users.
The term VPN has the full form of Virtual Private Network. It is a private network that enables users to send and receive data across the public network secretly without any limit. One can also change the location and IP address of a device by connecting it to another VPN. There are three types of VPN –
- Remote access
- Site-to-site VPN
- Extranet-based site-to-site VPN
Advantages of Internet Network Technologies
Now, what are the advantages of computer network technologies? Here is a complete list of advantages –
- Computer networking makes the communication system very easy. In old days, we had to go physically to send a message at any place. Now, we can instantly exchange such messages sitting in our home or office.
- Physical communication was very costly due to the transportation cost and others. But we can communicate with people using network technologies at a minimal cost of money.
- Computer network technologies are highly flexible.
- It is a time-saving technology.
- We can share text, audio, and video with any users connected with this technology.
Disadvantages of Internet Network Technologies
Besides the advantages, the computer network technologies also have some disadvantages which are listed below.
- Networking technology has a risk of data being stolen.
- To control this technology we need efficient technicians.
- There is a possibility of attacking the devices with viruses and malware.
- It needs an exclusive set-up to use which is hard to handle for many people.
- Computer internet networks are harmful to birds and some other animals. Even humans can also be affected by these technologies.
Popular Network Technology Companies
There are several network companies across the world. These companies provide networking to the users. Also, they offer jobs to suitable candidates in their companies. Here is the list of some popular networking companies –
- Arista network
- Aruba networks
- Big switch networks
- Cisco systems
- Cumulus networks
- Dell EMC
- Extreme network
- Juniper networks
