4. Memory : Memory is defined as : “ The internal storage media of a computer is called as Memory” User can save Information, data, programs etc These Instruction we can save in memory with the help of CPU 4 4/5/2019

5. Memory :- 5 4/5/2019

6. What's a bit:- Bit is the smallest unit of memory Bit is abbreviated as Binary Digit Bit can be 1 or 0 1 mean ON 0 mean OFF So memory is a space in computer which store 0 and 1 in form of information 6 4/5/2019

7. Memory space limitations:- Bit KB MB GB TB ZB 4/5/2019 7

8. TRIANGLULAR BITS difference :- 4/5/2019 8

9. Importance of Memory:- Memory is a Important part of Computer Without Memory there would be no computer It is used for storing both Instructions executed and Data The CPU accesses each location in the memory by using a technique number called as Memory Address Memory helps to save Data. 9 4/5/2019

10. Types of Memory : The Memory is of two types :- Primary Memory Secondary Memory 10 4/5/2019

11. Types of Memory :- 11 4/5/2019

12. Primary Memory :- “Primary Memory is also called Volatile Memory ” It is a temporary memory 12 4/5/2019

13. Primary Memory :- In primary memory contents lost when we turn off our Computer We never store our data permanently in it Select the part of memory to store data but doesn't store data permanently Select part to store randomly Example: RAM 13 4/5/2019

14. RAM : ( Random Access Memory ) “RAM perform both Operations Read and write ” No Data loss happened if power failure Occurs . 14 4/5/2019

15. RAM:- 15 4/5/2019

16. Types of RAM are : DRAM ( Dynamic RAM) SRAM ( Static RAM ) DrRAM (Dynamic rambes RAM) 16 4/5/2019

17. Secondary Memory :- “Secondary memory is also called Non-Volatile memory ” It is a Permanent Memory 17 4/5/2019

18. Secondary Memory is Useful for External storage media For Example :- Floppy Disk ,Magnetic Disk, Magnetic tape etc….. No Contents Lost Data ,instruction save permanently Example : ROM 18 4/5/2019

19. ROM (read only memory :- “ROM perform only Read operation” No Data loss happened if power failure Occurs . 19 4/5/2019

20. ROM :- 20 4/5/2019

21. Types of ROM :- Types of ROM are :- PROM (Programmable ROM) EROM (Erasable ROM) EEPROM (Electrical Erasable Programmable ROM ) 21 4/5/2019
