Transcript

  • 1. Presented To: Miss Nusrat Presented By: Sameea Mahmood Kiran Zulfiqar Mubashra Tajamul
  • 2. MEMORY
    • Please send the data in slot number.
    • 10011101100001001111101100101
    • Ok, here it comes.
    • 01001100
    CPU RAM
  • 3. "INTRODUCTION"
    • Consists one or more chips on the motherboard.
    • Data and instructions are stored to execute.
    • Primary storage device.
    ROM (nonvolatile) Motherboard CPU RAM ( volatile )
  • 4. MEMORY (RAM) HARD DISK COMPACT DISK FLOPPY DISK TAPE More expensive Cost Less expensive Faster Speed Slower DIAGRAM:
  • 5. "TYPES OF MEMORY"
    • Temporary Memory (RAM)
    • Permanent Memory (ROM)
  • 6. " TEMPORARY MEMORY "
    • Chips on a small circuit board
    • Entire memory directly accessible
    • Program load in RAM before execution
  • 7.
    • Volatile memory
    • Play important role in processing speed
    • Bigger RAM = Large capacity to save data
    • Smallest RAM = Low capacity to save data
    • Measured in Bytes
    • Change data during execution
    • Lose its contents when computer is turned off
    Characteristics:
  • 8. "TYPES OF RAM"
    • DRAM (Dynamic RAM)
    • SRAM (Static RAM)
    CPU CACHE MEMORY MAIN MEMORY
  • 9. " DIFFERENCE "
    • It is less complex & more compact
    • It is more complex & less compact
    • It utilizes low power
    • It utilizes more power
    • it is less expensive
    • It is more expensive
    • It is slower
    • It is faster
    DRAM SRAM
  • 10. "FLESH MEMORY"
    • Non-volatile
    • Portable device
    • Intelligent device
    • A camera with a flesh card, picture
    • stored on a card by turning millions of switches on
    • & off
  • 11. "UNIVERSAL SERIAL BUS PORT"
    • Faster port
    • Also called Pen device
    • Computer have one or two USB port
    • Multiple devices attached to USB through daisy chain
    • Alternate to daisy chain USB hub
    • Original hub port could transfer data at only 12Mbps
    USB PORT CONNECT WITH Printer, Scanner, Keyboard, H.D.D
  • 12. "COMPARISION"
    • Non intelligent device
    • Intelligent device
    • Not accept binary no
    • Accept binary no
    • Small size
    • Large size
    • No switches
    • Have switches
    • Portable
    • Portable
    USB FLASH MEMORY
  • 13. "PARMANENT MEMORY"
    • Small set of instructions
    • Non-volatile
    • instructions in ROM prepare computer for use
  • 14.
    • Do not change data during execution
    • Store data & instructions permanently
    • Does not lose its contents when
    • computer is turned off
    • Only read & use data
    Characteristics:
  • 15. "TYPES OF ROM"
    • PROM ( Programmable ROM )
    • EPROM ( Erasable PROM )
    • EEPROM ( Electrically EPROM )
  • 16. "DIFFERENCE"
    • It provides more usability as instruction are written many time
    • It provides less usability as instruction are written only once
    • User can write instructions many times
    • user can write instructions only once
    • Electronically programmable memory
    • Programmable memory
    EPROM PROM
  • 17. "DIFFERENCE"
    • Instructions are written into ROM at manufacturing time
    • Instructions are written into the RAM at the time of execution
    • Data cannot be changed or deleted
    • Data can be changed or deleted
    • Instructions written in ROM can only be read
    • RAM enables data read & write to memory
    • Permanent memory
    • Temporary memory
    ROM RAM
  • 18. "QUERIES" HAVE YOU ANY QUESTIONS ABOUT MEMORY?
