From the equation above we know ,the capacity of RAM needed to display depends on resolutions and the color depths

High color(16bit) and Deep color(32bit)

Color depth is the number of distinct colors that can be represented by a piece of hardware or software

List two typical monitor color depths.

d. Consider that the higher the resolution and the higher the color depth, the more system resources are required to display output on the monitor.

i. Use the resolutions from part b and the color depths from part d to calculate the amount of RAM required to display the image.

1024*768, 32bits, RAM = 1024*768*32/8 = 3145728 Bytes ,about 3M

ii. Explain the calculation you made in part e.i in a way that confirms the statement made at the beginning of part e—that "the higher the resolution and the higher the color depth, the more system resources are required to display output on the monitor."

1. Port Identification

Consider the following devices:

The Label A is Mouse
The Label D is Printer
The Label A is Keyboard
The Label G is Modem
The Label E is Speaker
The Label B is Digital camera
The Label H is Ethernet jack
The Label F is Monitor

For the following questions, indicate which device(s) should be plugged in which port(s) A-H shown in the diagram below.

a. What device(s) can be plugged into port A?

i. What is the name of this port? PC/2

ii. Is this a serial port or parallel port? Serial port

b. What device(s) can be plugged into port B?

i. What is the name of this port? USB port

ii. Is this a serial port or parallel port? Parallel port

c. What device(s) can be plugged into port C?

i. What is the name of this port? DB-9

ii. Is this a serial port or parallel port? Serial port

d. What device(s) can be plugged into port D?

i. What is the name of this port? DB-25F

ii. Is this a serial port or parallel port? Serial port

e. What device(s) can be plugged into port E? Speaker and Microphone

f. What device(s) can be plugged into port F? Monitor

g. What device(s) can be plugged into port G? Modem cable

h. What device(s) can be plugged into port H? Ethernet cable
