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!
Most <u>Malware</u> focus on gaining entry over the internet to a secure computer system by finding a working user ID and password combination.
<u>Explanation:</u>
A malware is a small computer program which works on the user’s system without knowing to the user. Different malware works differently.
Some malware sits on the user computer, create multiple unnecessary files and make the hard drive full, some people create viruses to show their computer skills which they tend to prove in a wrong way, some malware sits in the computer to steal data especially while using internet.
So there are malware's like Virus, Worm, Trojan, spyware, etc.
