NETWORK

                “The interlink connection between device or node through a communication link (medium) to communicate data is called network.” 

CRITERIA FOR A DATA COMMUNICATION NETWORK

                Some criteria or specification that a data communication network must meet, in order to exchange data. For a reliable and a proper network, following three criteria must carry by specific network.  

                                1.  Performance

                                2.  Reliability

                                3.  Security 

1.      Performance

Performance can measure by different aspect and factor such as. The transmit time and response time, performance of network like active user transmission medium type, how fast the data travel between medium also protocol paly role in performance.

2.   Reliability

Reliability is measured in term of network failure and duration in which the failure recover. It is one of the most important criteria after security on which the network should fall its maximum hold. Reliability in term of the network is able or not when require arise, if the network down in-between works then it will count as failure.

3.   Security

Security includes the data protection from virus and Malicious/unauthorized user access. The data sent over network should reach from source to destination without any loss and interrupt in the way.  The most important factor of data communication network although performance and reliability count it’s important but security is one of most sensitive word of need now a day.

The criteria of computer network says about the quality of network.

Q. What is the criteria for a good network, name it?

Ans: For a good  network, the following three network criteria must meet. 1. Performance  2. Reliability  3. Security
