RAM, ROM, and Virtual Memory

RAM, ROM, and Virtual Memory

1. RAM is used to store frequently used program instructions that are sent to the CPU to be decoded and executed.

2. Read-only memory is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM can not be edited

3. virtual memory is used when RAM is full of too much data. The operating system moves data from processes that are not immediately needed out of the RAM and stores them in virtual memory in the hard disk drive.

4. ROM contains the start-up instructions for a computer, also known as the firmware. Most modern computers use flash-based ROM. It is part of the BIOS chip, which is located on the motherboard

5. Virtual memory is much slower than main memory because processing power is being taken up by moving data around, rather than just executing instructions.

6. RAMs are slower than cashes because they are further away from the CPU so it takes longer for the computer to access the data.

7. volatile is used to explain that when the computor turns off the memory content is lost.

8. BIOS = Basic input/output system. It is the program a personal computer's microprocessor uses to get the computer system started after you turn it on
