RAM, ROM and CPU

ROM Vs RAM: What is used to boot up the computer when it is switched on...

• RAM

• ROM

Which component receives its instructions directly from the RAM?

• Motherboard

• BIOS

• CPU

• Hard Drive

Which TWO statements are about RAM?

• Is High Speed, Volatile memory is used as the main memory in a computer. It can be read and written to.

• Non-volatile memory.

• Volatile = temp memory, requires power to retain it data.

• it can ONLY BE READ, not written to.

Memory that uses secondary storage so that it seems like an entire program is running from RAM

• Cache Memory

• Virtual Memory

• Flash Memory

• Registers

Virtual memory is used

• when the RAM is not enough to contain all of the programs and data currently being used
• every other time a program is used
• as a secondary storage medium for long term storage of documents
• when the CPU is getting overheated

Why is Virtual Memory needed or used by a computer?

• When RAM becomes full because of too many programs running at once

• When ROM is too small and struggles to store the Operating System

• When users wish to store data on an external server such as 'the cloud'

• When chosen by the user or computer administrator

The purpose of ROM is to...

• Provide backup storage
• Acts as a fast type of memory for the CPU
• Store application files
• Store the BIOS instructions

Volatile memory that runs the Operating System and other applications

• Cache Memory
• RAM
• Virtual Memory
• Registers

Very fast memory that is built into the CPU. Blocks of memory copied here from RAM.
