Assuming that it takes 2 nsec to copy a byte, how much time does it take to completely rewrite that screen of an 80‐character x 25 line text mode memory‐mapped screen? what about a 1024 x 768 pixel graphics screen with 24‐bit color?

a.  0.04 msec

b. 23.59 msec

Explanation:

a. Text Mode

2 * 80 *25 = 4000 bytes

1 byte take 2nsec time so, 4000 bytes take

4000 * 10 nsec = 40000 nsec = 0.00004 sec = 0.04 msec

b. Graphics:

24 bit color

3 bytes per pixel

1024 * 768 * 3 = 2 359 296 bytes

2 359 296 * 10 nsec = 23592960 nsec = 0.02359296

sec =23.59 msec

since it can be assumed that what aslam is making is a template by compiling all the commonly used excel formatting in several worksheets in an excel document, aslam can choose to save it using the .xltx or .xltm format instead. thus, aslam can distribute the templates he has made to his team members in an easier manner.

the correct answer is a) her connection with a character

this is correct on edgnuity : )
