This document provides an overview of computer memory, including definitions, history, and different types. It defines computer memory as any physical device capable of storing information temporarily or permanently. The history of computer memory is traced back to Charles Babbage's analytical engine in 1834, which used punch cards. There are different types of memory divided based on how information is stored, including volatile memory, non-volatile memory, and virtual memory. Volatile memory only maintains data while powered, while non-volatile memory can retrieve stored information after power cycling.

- 1. IT TOOLS FOR BUSINESS TOPIC: MEMORY PRESENTED BY- DEPARTMENT: BACHELOR OF BUSINESS ADMINISTRATION YEAR:1ST, SEM:1 NAME: SOUMYAJIT BANERJEE STUDENT CODE: BWU/BBA/18/020
- 2. CONTEXTS – DEFINATION OF COMPUTER MEMORY – HISTORY – TYPES OF MEMORY – WHAT IS RAM – TYPES OF RAM – WHAT IS ROM – TYPES OF ROM – MEMORY DIVISION ACCORDING TO STORED INFORMATION – VOLATILE MEMORY – NONVOLATILE MEMORY – VIRTUAL MEMORY
- 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
