Introduction
Computer peripherals and accessories are external devices that enhance the functionality and usability of a computer system. Competitive exams frequently test whether candidates can classify peripherals correctly as input, output, or storage devices.
These questions are mostly classification-based and are easy scoring with clear concepts.
Pattern: Computer Peripherals & Accessories
Pattern
The key idea is to identify peripherals as external devices and correctly determine whether they perform input, output, or storage functions.
Step-by-Step Example
Question
Which of the following is an output peripheral?
Options:
A. Scanner
B. Joystick
C. Plotter
D. Keyboard
Solution
-
Step 1: Recall output devices
Output peripherals display or produce results from the computer. -
Step 2: Evaluate each option
Scanner, joystick, and keyboard send input to the computer. -
Step 3: Identify the output device
A plotter produces graphical output on paper. -
Final Answer:
Plotter → Option C -
Quick Check:
Produces printed graphics → Output device ✅
Quick Variations
• Questions may mix internal components with peripherals to confuse candidates.
• Accessories like webcam, microphone, and external hard drive are common options.
• Sometimes multifunction devices (printer + scanner) are tested.
Trick to Always Use
- Step 1 → Sends data to computer → Input peripheral
- Step 2 → Displays or produces result → Output peripheral
- Step 3 → Stores data externally → Storage peripheral
Summary
Summary
- Peripherals are external devices connected to a computer.
- Input peripherals send data to the computer.
- Output peripherals display or produce results.
- Storage peripherals store data externally.
Example to remember:
Keyboard → Input | Monitor → Output | External Hard Disk → Storage
