A noise that occurs when the Hard Disc Drive disc is detached from it's arm
A method of encrypting a Hard Disc Drive disc
Why do computers need RAM?
To store the boot up sequence for the computer quickly
To allow the CPU to access Data and Instructions securely
To allow the CPU access Data and Instructions quickly
To store the boot up sequence for the computer securely
What do the instructions in the ROM do when the computer starts up?
Transfers the Operating System from Secondary Storage to the RAM
Checks the system for viruses
Checks the system for errors
Transfers the Operating System from ROM to the RAM
What causes slow down in a computer?
Too many programs running meaning the RAM must be used multiple times, slowing it down
Too many programs running meaning Virtual Memory must be used, which is slower
Opening and closing too many programs in a short time meaning the RAM must be used multiple times, slowing it down
Opening and closing too many programs in a short time meaning Virtual Memory must be used, which is slower
How does a computer use virtual memory?
Sends less used data to the Secondary Storage
Stores less used data in the RAM
