Answer:
D) can access main memory at the same time as the main CPU
Explanation:
DMA is short for Direct Memory Access, these controllers allow the device to transfer data directly to and from the memory modules without interfering with CPU processes. Therefore it can access main memory at the same time as the main CPU. Thus freeing up CPU processing power for other tasks while also retrieving the data necessary.

The answer is a Scroll bar, the description fits perfectly because you need to move it to see more of the content you are viewing, and it wont be completely. when the item does appear completely on screen then the bar is relatively large and there is no need for scrolling, however the opposite occurs during when you cannot see all of it.
Answer:
A = 120
B = 40
C = 70
Solution:
As per the question:
Manufacturer forced to make 10 more type C clamps than the total of A and b:
10 + A + B = C (1)
Also, 3 times as many type B as type A clamps are:
A = 3B (2)
The total no. of clamps produced per day:
A + B + C = 330 (3)
The no. of each type manufactured per day:
Now, from eqn (1), and (3):
A + B + 10 + A + B = 330
2A + 2B = 320
A + B = 160 (4)
Now, from eqn (2) and (4):
3B + B = 160
B = 40
Since, A = 3B
A = 
A = 120
Put the values of A and C in eqn (3):
120 + 40 + C = 330
C = 70
