1. 11:15:01 Storage device

2. Computer memory Primary storage 11:15:01

3. Type of internal memory There are two type of memory: RAM (Random Access Memory) ROM (Read Only Memory)

4. 11:15:01 It is used by the computer to store programs and data that are currently being used; It is usually referred to as Computer’s RAM (Random Access Memory); It is also referred to as the Computer’s Immediate Access Store (IAS) Internal memory (RAM)

5. 11:15:01 Internal memory (RAM)

6. 11:15:01 Internal memory can not hold all the data and programs that a computer might need; It only holds the data and programs that are in use at a particular moment in time, and empties and refills itself as different programs and files are used Internal memory (RAM)

7. 11:15:01 Internal memory is volatile memory; This is because this memory is emptied (i.e its contents are lost) when the computer is turned off; Internal memory (RAM)

8. 11:15:01 It is “Random” because any part of the memory can be accessed directly by the computer; RAM is made up of locations, also known as CELLS; Each location has a unique address that never changes. Internal memory (RAM)

9. 11:15:01 When the computer is switched on, the operating instructions, computer programs, and data are moved into the RAM as required; RAM empties every time the computer is switched off – that is why work has to be saved before the computer is switched off!! Internal memory (RAM)

10. 11:15:01 RAM is usually measured in “megabytes”; The more RAM a computer has, the more it can do. Random Access memory (RAM)

11. 11:15:01 RAM is very fast compared to backup storage. It is about one thousand million times faster! That why a computer needs both a backup storage and RAM. It uses RAM for speed and the hard disk to store data whilst switched off. Random Access memory (RAM)

12. 11:15:01 Read Only Memory (ROM) is not lost when the computer is switched off; All computers have a small amount of ROM; This is so that essential instructions can be stored, e.g Instructions to boo the computer. Internal memory (ROM)

13. 11:15:01 Instructions stored in the ROM enable the computer to check the hardware and load the operating systems; Embedded computer systems usually have their programs stored i ROM; ROM are not as fast as RAMs Read Only Memory (ROM)
