Answer:
For question a, it simplifies. If you re-express it in boolean algebra, you get:
(a + b) + (!a + b)
= a + !a + b
= b
So you can simplify that circuit to just:
x = 1 if b = 1
(edit: or rather, x = b)
For question b, let's try it:
(!a!b)(!b + c)
= !a!b + !a!bc
= !a!b(1 + c)
= !a!b
So that one can be simplified to
a = 0 and b = 0
I have no good means of drawing them here, but hopefully the simplification helped!
Answer: I think its true but I'm not like 100% sure sorry
Explanation: i dont know just seems right
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.
