Computer Networks


A computer network is a grouping of two or more devices linked by a medium to exchange data. We can easily send and receive data to and from a computing device using a computer network. In this article, we are going to discuss some basic characteristics of Computer Networks.

Basic Characteristics of Computer Network

Basics of Computer Networks

1. Security

Security is one of the most essential characteristics of a computer network. Most businesses nowadays rely on computers, which are accessed through networking. As a result, if computer network technology is not robust and secure, unauthorized access to the company's critical data might be possible. However, nowadays, computer networking tools primarily provide the highest level of security and prevent any unauthorized access.

2. Reliability

Computer networks are very reliable tools, and users can easily interconnect their devices with their help. Computer networks have alternative sources of supply to provide high reliability. Their networking experience remains consistent even if users need to print, check messages, attend a meeting, or access data from another computer.

3. Scalability

Scalability refers to the ability to scale up in response to changing needs while maintaining high performance. The internet is the best example of scalability; many new users connect via the internet and communicate with other devices, but our network still works properly.

4. Flow of Data

Users can access and transmit data such as files, documents, and other types of information with the help of computer networking. It is a crucial feature of a computer network as it allows data to flow from one device to another.

5. High performance

The performance is evaluated using the time required by a command. If it requires less time to transfer the data and the response is quick, it is a significant advantage for the users to transfer data and use multiple resources. The performance can be increased using multiple processors.

6. Fault tolerance

Fault tolerance is also a great feature offered by computer networks. Let’s suppose two devices are connected with both wired and wireless mediums. If the sender’s device sends the information, and the receiver’s device has a blockage at its wireless medium. It will find the other best alternative medium to send the information to the receiver’s device, which is a wired medium in this case. Using this, they can continue to work even if the networking is down or damaged. This is how fault tolerance works.

7. Quality of Service (QoS)

It means users can prioritize and customize their data transmission while also minimizing any transmission delays. It also allows for the loss of any data if it occurs regularly. As a result, another feature of a computer network is that it provides a high level of service to its users.

8. Compatible With Hardware and Software Components

Another great feature of computer networking is allowing multiple connected devices to access the same software. It entails that the same software can be used on various devices. It improves compatibility, allowing this work to be completed. As a result, computer networks make it easier to use software and make the best use of physical components.

Frequently Asked Questions

What are the characteristics of the network layer?

The OSI model's network layer has the following characteristics:
Establishing paths for the transfer of data packets between network devices is the responsibility of this role.
Traffic direction.
Service and logical network addresses are two types of addresses.
Switching packets.
Packet Sequence Control

What are the characteristics of effective networks?

Effective Network Qualities
Breadth: Our network is made up of strong connections with a wide range of people.
Connectivity: Our network creates connections or bridges between people and groups who might not otherwise interact.
Dynamism: our network is made up of a dynamic set of extended ties that changes over time as we do.

What are the characteristics of the physical layer?

The Physical Layer manages to transmit unstructured raw data streams over a physical medium. It maintains the data rate (how many bits a sender can send per second). It performs bit synchronization. It aids in the selection of a transmission medium (direction of data transfer)

What are the types of computer networks?

There are many different types of computer networks, but the most common ones are: LAN (Local Area Network), WAN (Wide Area Network), WLAN (Wireless Local Area Network), MAN (Metropolitan Area Network), and CAN (Campus Area Network).
