1. ROM

   • RROM stands for read only memory which means it can execute orders but cannot write them.

2. RAM

   • RAM stands for random access memory and is A volatile storage. This means that it is wiped every time the computer is turned off.

3. HArd drive

   • Hard drive IS a non-volatile storage that is read and write.

4. CACHe

   • Stores data and speeds up the processor.

5. volatile

   • This is data that disappears after the device is switched off.

6. The CPU is the central processing unit and it tells everything what to do and makes all the calculations.

7. Virtual memory

   • Volatile memory is memory that appears to exist as main storage although most of it is supported by data held in secondary storage, transfer between the two being made automatically as required.

8. fetch, decode, execute

   • Fetch receives a message or instruction,

9. motherboard

   • The motherboard is the main component of a computer. It is a board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots.

10. components

    • Computer hardware is the physical parts or components of a computer, such as the monitor, keyboard, computer data storage, graphic card, sound card and motherboard. By contrast, software is instructions that can be stored and ran by hardware.

11. secondary storage

    • Auxiliary memory, also known as auxiliary storage, secondary storage, secondary memory or external memory, is a non-volatile memory that is not directly accessible by the CPU, because it is not accessed via the input/output channels.
