Unit 2 Lab
Exercise 2.1.1: The data is transmitted as a signal, using a pattern and timing via the media so the devices can interface with each other.
Exercise 2.1.2: The NIC card does most of this work.

Lab 2.1 Review
1) Peripheral devices are added to your computer, e.g. mouse, keyboard or DVD Drive. A network device can be accessed over a network like a printer.
2) You want to limit your connections because of the amount of bandwidth it can chew up.
3) The devices act as equals on the network. There is no infrastructure involved.
Exercise 2.2.1: To buy 30 printers at $120.00 each is $3600.00. A single high-capacity printer at $500.00 would be more cost effective. If there is only 1 printer for 30 people it might cause an information jam when more than 1 person is printing at the same time. If 2 back up printers were purchased, it would only cost a total of $1500.00 versus the $3600.00. A grand total of 7 printers would cost $3500, still coming in less than $3600.00 for 30 printers.
Exercise 2.2.2: A total of 4 (3.66) shared printers would be needed to handle that capacity. But you need to think about paper jams, running out of paper and...
