3. DEFINATION OF
COMPUTER MEMORY
– COMPUTER MEMORY IS ANY PHYSICAL DEVICE CAPABLE OF
STORING INFORMATION TEMPORARILY OR PERMANENTLY.

4. HISTORY
– IN 1834 , CHARLES BABBAGE BEGINS TO BUILD HIS
"ANALYTICAL ENGINE", A PRECURSOR TO THE COMPUTER. IT
USES READ-ONLY MEMORY IN THE FORM OF PUNCH CARDS.

6. WHAT IS RAM?
– IT IS THE PHYSICAL HARDWARE INSIDE A COMPUTER THAT
TEMPORARILY STORES DATA, SERVING AS THE COMPUTER'S
"WORKING" MEMORY.

7. TYPES OF RAM
Static random-access
memory(SRAM)
Dynamic random-access
memory(DRAM)

8. WHAT IS ROM?
– READ-ONLY MEMORY (ROM) IS A TYPE OF STORAGE MEDIUM
THAT PERMANENTLY STORES DATA ON PERSONAL
COMPUTERS (PCS) AND OTHER ELECTRONIC DEVICES.

9. TYPES OF ROM
Programmable
read-only
memory (PROM)
Easable
programmable
read-only
memory(EPROM
)
Electrically Erasable
Programmable Read-
Only
Memory(EEPROM)

10. MEMORY DIVISION ACCORDING TO
STORED INFORMATION
– VOLATILE MEMORY
– NON-VOLATILE MEMORY
– SEMI-VOLATILE MEMORY
– PROTECTED MEMORY

11. VOLATILE MEMORY
– VOLATILE MEMORY IS COMPUTER STORAGE THAT ONLY
MAINTAINS ITS DATA WHILE THE DEVICE IS POWERED.

12. NONVOLATILE
MEMORY
– NON-VOLATILE MEMORY (NVM) OR NON-VOLATILE
STORAGE IS A TYPE OF COMPUTER MEMORY THAT CAN
RETRIEVE STORED INFORMATION EVEN AFTER HAVING
BEEN POWER CYCLED.

13. PRIMARY MEMORY/
MAIN MEMORY
– PRIMARY MEMORY IS COMPUTER MEMORY THAT
A PROCESSOR OR COMPUTER ACCESSES FIRST OR
DIRECTLY.
– IT ALLOWS A PROCESSOR TO ACCESS RUNNING
EXECUTION APPLICATIONS AND SERVICES THAT
ARE TEMPORARILY STORED IN A SPECIFIC
MEMORY LOCATION.
– EXAMPLE: RAM.

14. SECONDARY MEMORY
– SECONDARY MEMORY IS COMPUTER MEMORY THAT
IS NON-VOLATILE AND PERSISTENT IN NATURE AND
IS NOT DIRECTLY ACCESSED BY A
COMPUTER/PROCESSOR.
– IT ALLOWS A USER TO STORE DATA THAT MAY BE
INSTANTLY AND EASILY RETRIEVED, TRANSPORTED
AND USED BY APPLICATIONS AND SERVICES.
– EXAMPLE: READ-ONLY MEMORY (ROM), FLASH
DRIVES, HARD DISK DRIVES (HDD), MAGNETIC
TAPES AND OTHER TYPES OF INTERNAL/EXTERNAL
STORAGE MEDIA.

15. CACHE MEMORY
– is high-speed static random access memory (SRAM) that a
computer microprocessor can access more quickly than it
can access regular random access memory (RAM).
– EXAMPLE: The Intel 80486 microprocessor

16. VIRTUAL MEMORY
– IN COMPUTING VIRTUAL MEMORY IS A MEMORY
MANAGEMENT TECHNIQUE THAT PROVIDES AN "IDEALIZED
ABSTRACTION OF THE STORAGE RESOURCES. THAT ARE
ACTUALLYAVAILABLE ON A GIVEN MACHINE“ WHICH
"CREATES THE ILLUSION TO USERS OF A VERY LARGE (MAIN)
MEMORY
