What are the three criteria necessary for an effective and efficient network?

A network must meet a certain number of criteria to become useable in real world situation. Most important of these criteria are the three criteria as follows.


1. Performance:

Performance is a measurement of various factors such as the amount of time requires for messages to travel from one device to another, the time it requires to get a response starting from an inquiry. Performance of a network, however also depends on a number of factors such as number of active users, type of the transmission medium, capabilities of the connected hardware and efficiency of the software etc.

2. Reliability:

Network reliability is measured by the frequency of failure, time it takes to recover from failure, the network’s robustness. If a network isn’t reliable it would be hard to transfer big data as the connection might loss in the midway and can make longer delay than expected.


3. Security:

Network must be secured. The data that is sent should reach its destination safely without any third-party reading or altering or destroying the data in the midway. Along with this, a network must have secured procedures to recover from data losses and breaches.
