The main purpose of a network is to cover a large area so that it can interconnect as many elements as possible. Therefore, the larger a network is, the more effective it is. For example, if you are networking for employment purposes, you are more likely to get good results if your network involves a large number of people. Another example would be the internet, which is a network that becomes more effective and efficient the more computers are connected to it.
The effectiveness of a network is related to the configurations and the way that network is being used. The size of the network has no influence on its effectiveness, but small networks are easier to maintain, manage and configure, because it is easier to maintain communication between network members.
