Suppose you are to design a LAN for a company that has 100 employees, each given a desktop computer attached to the LAN. What should be the data rate of the LAN if the typical use of the LAN is shown below:
1. Each employee needs to access the Internet at 250 Kbps. This can happen for 10 employees simultaneously.
2. Each employee may receive 10 e-mails per hour with an average size of 100 kilobytes. Half of the employees may receive e-mails simultaneously.
