  3. 3. Memory & Storage • Terms which are commonly used alternatively. • Memory refers to the physical devices used to store programs on a temporary or permanent basis for use in a computer. • Storage refers to the a technology consisting of computer components and recording media used to retain digital data.
  4. 4. Computer storage types
  5. 5. Internal Storage • Also known as Primary Memory,Main Memory • The only one directly accessible to CPU • Continuous interaction with CPU • Any data actively operated is stored in internal storage • Contains RAM, ROM, Processer Registers ,Processer Cache.
  6. 6. RAM (Random Access Memory) • Volatile • Store the currently processing details data etc • Allow data to be written and read in a rough manner • System speed and performance is dependent to this • Mainly two types DRAM & SRAM
  7. 7. ROM(Read Only Memory) • Non Volatile • Contains startup program (BIOS) of system • Helps in System Booting • Mostly programmed at the time of manufacture • Also have different types PROM,EPROM,EEPROM,FLASH MEMORY
  8. 8. • Processor registers • Inside processor ,32-64 bit • Fastest of all the class of memory • Processor cache • Intermediate between registers and Main Memory(RAM) • Fast & Small size
  9. 9. External Storage • Also known as Secondary storage , auxiliary storage • Indirectly accessed by CPU • Input/output channel are used • non-volatile • Keep data for long run & future analysis • Less Expensive • Hard drive, Optical storage, Flash memory, Magnetic Tapes, Ram disks etc
  10. 10. Storage Devices • Storage device is a device for recording (storing) information (data). Recording can be done using virtually any form of energy. • Function is same only the mode of working changes • Volatile and Non volatile
  11. 11. Portable Storage • Any storage device which is mobile can be stated as portable. • The device must be platform independent • The very first commonly used portable storage is Floppy . • Optical storage • Flash Drive • PSD • Wireless PSD
  12. 12. Hard Disk • The most commonly used Secondary storage • a data storage device used for storing and retrieving digital information using rapidly rotating disks • The data is read from the disk by detecting the transitions in magnetization. User data is encoded using an encoding scheme
  13. 13. components of a computer HDD
