what is hard disk and its type

hard disk

A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.

types of a hard disk


Currently, we can group hard drives into 5 types:
  • Parallel Advanced Technology Attachment (PATA)
  • Serial ATA (SATA)
  • Small Computer System Interface (SCSI)
  • Solid State Drives (SSD)
  • AND ID hard disk this is not in use now

what is a memory and type

what is a memory Computer  memory  is any physical device capable of storing information temporarily or permanently. For example, Random Access Memory ( RAM ), is a volatile memory that stores information on an  integrated circuit  used by the  operating system , software , and  hardware . type of memory 1st-Volatile memory Volatile memory is computer memory that requires power to maintain the stored information. Most modern  semiconductor  volatile memory is either static RAM ( SRAM ) or dynamic RAM ( DRAM ). SRAM retains its contents as long as the power is connected and is easy for interfacing, but uses six transistors per bit. Dynamic RAM is more complicated for interfacing and control, needing regular refresh cycles to prevent losing its contents, but uses only one transistor and one capacitor per bit, allowing it to reach much higher densities and much cheaper per-bit costs. SRAM is not worthwhile for desktop system mem...

what is Operating system

                       Operating system             An  operating system  ( OS ) is  system software  that manages  computer hardware  and  software  resources and provides common  services  for  computer programs . All computer programs, excluding  firmware , require an operating system to function. Time-sharing  operating systems  schedule tasks  for efficient use of the system and may also include accounting software for cost allocation of  processor time ,  mass storage ,  printing , and other resources. For hardware functions such as  input and output  and  memory allocation , the operating system acts as an intermediary between programs and the computer hardware, [1] [2]  although the application code is usually executed directly by the hardware and frequently makes  sys...
