  1. Addition in the number of computers in purchase department, will affect the efficiency of head office’s LAN? Give your answer is Yes/No with appropriate reason.

Answer: In network science, the efficiency of network is a measure of how efficiently it exchanges the information. The concept of efficiency can be applied to both local and global scales in a network. On a global scale, efficiency quantifies the exchange of information across the whole network where information is concurrently exchange. The local efficiency quantifies a network’s resistance to failure on a small scale.
