2. Introduction to Computers
• A computer is an electronic device
that processes data and performs
tasks based on software
instructions.
• It follows the Input Process
→ →
Output cycle.

3. Characteristics of Computers
• 1. Speed – Executes millions of instructions
per second.
• 2. Accuracy – Performs calculations with
precision.
• 3. Automation – Operates automatically after
starting.
• 4. Versatility – Can perform different types of
tasks.
• 5. Storage – Stores large amounts of data.
• 6. Connectivity – Communicates over
networks and the internet.

4. Classification of Computers
• Supercomputers – Used for scientific
research.
• Mainframe Computers – Used in large
organizations for bulk data processing.
• Minicomputers – Used in mid-size
businesses.
• Microcomputers (PCs) – Includes laptops,
desktops, and tablets.
• Embedded Computers – Found in cars,
ATMs, and smart appliances.

5. Types of Computers Based on
Data Handling
• Analog Computers – Used in
scientific simulations (e.g., weather
forecasting).
• Digital Computers – Process data in
binary (used in offices, homes).
• Hybrid Computers – Combination of
analog and digital (used in medical
devices).

6. Importance of Computers in
Education
• E-Learning Platforms (Google Classroom,
Coursera, Udemy).
• Smart Classrooms with interactive
whiteboards.
• Online Research & Libraries for academic
growth.
• Programming & Coding for students.
• Virtual Labs & Simulations in science
education.

7. Summary
• Computers are electronic devices used
for processing information.
• They have high speed, accuracy, and
versatility.
• Classified based on size
(supercomputer to embedded systems)
and data handling (analog, digital,
hybrid).
• Computers play a vital role in
education and modern learning
environments.
