Components

Question 1

Types of Computer Cases?

Answer 1

Horizontal, full-tower, compact-tower, all in one

Question 2

Main role of PSU?

Answer 2

As the computer components require DC current and the outlet provides EC current we need something to convert it. So the PSU converts EC current to lower voltage DC current
