Peripheral management and drivers

The purpose and functionality of operating systems: Peripheral management and drivers

1.5.1 Operating Systems

Operating Systems — Note 4 of 6

What you need to know

The OS manages peripheral devices (keyboards, mice, printers, monitors) using software called drivers. A driver acts as a translator between the OS and the hardware device.

What to know

Key terms

Exam tipCommon mistake

Peripheral Management: The operating system's control of external devices, ensuring they communicate correctly with the computer using drivers.
Peripheral: A device connected to the computer, such as a keyboard, mouse, printer, or monitor.
Driver: A small program that acts as a TRANSLATOR between the operating system and a hardware device, allowing them to communicate.
Each type of hardware needs its own SPECIFIC driver — the OS cannot communicate with a device without the correct driver.
Without the correct driver, a device may not work at all or may not function correctly.
Exam tip: A driver is a TRANSLATOR — it converts the OS's instructions into a format the specific hardware device can understand.
Common mistake: Saying 'all devices use the same driver'. Each device type needs its OWN specific driver.

Exam technique

Tip:When asked about peripheral management, don't just say it 'manages peripherals'. Explain what it INVOLVES: receiving data from input devices, transmitting data to output devices, installing/downloading device drivers.
Mistake:Saying peripheral management just 'manages the hardware' — this is rephrasing the question and scores 0.
