  • Fault (e.g. a page fault or some other exception caused by executing an instruction)
  • Interrupt (e.g. a keyboard interrupt or I/O finishing)
  • Trap (e.g. a system call)
<h3>How do I switch from user mode to kernel mode?</h3>
  • The mode bit is set to 0 in the kernel mode. It is changed from 0 to 1 when switching from kernel mode to user mode.
  • In the above image, the user process executes in the user mode until it gets a system call.
  • Then a system trap is generated and the mode bit is set to zero.

A normal HDMI signal has a colour depth of 8 bits per each of RGB colour. The maximum number
Marysya12 [62]

Answer: B

Explanation:

if each color can be represented as 8 bits and you have 3 colors total that would mean you would need 24 bits to represent the entirety of the RGB spectrum. And each bit can either be on or off so you have two choices for each one. So the total amount of colors you can have for 8bit RGB would be 2^{24} which is 16,777,216.
