Peripherals

Peripherals refer to any external devices that can be connected to a computer, enhancing its functionality. These devices are generally slower than the CPU and may hold up processing when waiting for input or output operations. For instance, when playing a game, loading the next level from a CD may delay the CPU’s tasks as it waits for data to be written to memory.

Examples of Peripherals

• Input/Output (I/O):

  • Hard Disk
  • CD/DVD (RW)
  • SSD (Solid-State Drive)
  • Flash Disk
  • Memory Card

• Input Devices:

  • Keyboard
  • Mouse
  • Scanner

• Output Devices:

  • Projectors
  • Printers

These devices are essential for interacting with the computer system and performing various operations like data storage, retrieval, and display.
