Features of Computer Networks
In this tutorial, we will be covering the features of Computer Networks.
Basically, Computer Network is a connection of two or more devices that are connected through a medium in order to exchange information. With the help of a Computer Network, you can easily send or receive data to or from a computing device.
Now its time to cover the important features of Computer Networks:
We will discuss each feature one by one in the following section:
1. Data Sharing
One of the most important features of a Computer Network is that with their help you can easily share the data between different systems that are connected with each other through transmission media.
Thus, resources can be easily shared between two or more devices over a network.
With the help of Computer Networks there are fewer chances for the occurrence of failure and in case if there is any failure then recovery is fast.
Security is one of the main characteristics of Computer Networks, Thus a computer network should be secure so that the data transmitting over the network should be safe from any unauthorized access.
Also, the data sent by the sending node should be received as it is at the receiving node, which simply means there should be no loss of data during the transmission of the data.
Another feature of a Computer network is scalability. The scalability of a computer network simply means that we can add new nodes or components to the network easily. Any computer network must be scalable so we can extend it easily by adding new nodes. After adding new nodes to the network the speed of connection decreases which leads to a decrease in the speed of transmission of data. Thus due to all these, there are more chances for the occurrence of error.
This problem can be resolved with the help of routing devices.
Let us take an example of this: Suppose there are 50 computers in a company for their 50 employees. Let's say the company hires another 100 employees and then the company adds 100 computers to the existing local area network then in that case LAN should allow the same.
The performance of a computer network is measured using response time and with the help of the speed of data transmission. For better performance, the response time of sending and receiving data from one node to another should be minimum.
There must be a central server for the computer network and this server must keep the backup of all the data that is shared over the network. And at the time of failure in the network this central server helps in the faster recovery.
7. Software and Hardware Compatibility
In the Computer Network, there must not be any limitation for all the computers in a computer network to use the same software and hardware.
Instead, the computer network should allow better compatibility between different software and hardware configuration.
With the help of a Computer network, it becomes very easy for all of us to share our knowledge and ideas with others for example: via email messaging, via video conferencing over the internet, everything becomes easy.
Thus we have covered different features of Computer Networks and with the help of the computer network, the communication becomes easy and efficient. Another feature of Computer networks is that they provide quality of service(QoS) by avoiding data loss, avoiding unauthorized access to the data, reducing delay in data transmission, and by managing the data traffic.
