Memory and Storage Devices

The computers require space to store information to operate effectively. These data can be in the form of documents, images, videos, programs and system files. The computer's storage and handling of this data are made possible with the help of memory and storage devices.

Primary Memory

  • The primary memory is linked to the CPU directly.
  • It is used when the computer is in action.
  • Primary memory is a very fast memory, but it has a small capacity.

RAM/ROM

RAM (Random Access Memory)

  • RAM is used to store data and programs.
  • It enables the computer to activate applications as well as alternate between activities.
  • The higher the RAM, the faster and better the performance.

ROM (Read Only Memory)

  • ROM has valuable instructions that aid in the startup of the computer.
  • These rules are set in stone and are not easily modified.

Secondary Storage Devices

Secondary Storage

  • Data is stored in secondary storage for a long period.
  • It will not fail to store data even when the computer is off, unlike the primary memory.
  • The capacity of secondary storage is larger than that of primary memory.

Types of Storage Devices

Hard Disk Drive (HDD)

  • It is a primary storage medium within a computer.
  • It holds files of the operating system, software and user data.

Solid State Drive (SSD)

  • An SSD is a superior and quicker storage device compared to an HDD.
  • It enhances the general computer performance.

External Storage Devices

The gadgets are applied to transmit or save information.

Examples:

  • External Hard Drive
  • Pen Drive
  • Memory Card

Need for Storage Devices

Storage devices are significant in:

  • Saving important documents
  • Backing up data
  • Installing software
  • Protecting files from loss
