INTRODUCTION TO COMPUTERS
A
computer is an electronic device that accepts data (input), processes it
using instructions, stores the data for future use, and produces results
(output). It is a powerful tool that helps humans solve problems, perform
calculations, and manage information efficiently. Modern computers range from
desktops and laptops to tablets, smartphones, and embedded systems.
Importance of Computers
1.
Speed
& Efficiency – Computers process millions of
calculations per second, saving time and effort.
2.
Accuracy – Unlike humans, computers minimize errors if instructions
are correct.
3.
Storage – Large amounts of data can be stored, retrieved, and
managed easily.
4.
Connectivity – Computers enable communication and information sharing
worldwide via the internet.
5.
Automation – Tasks that would take hours manually can be automated,
increasing productivity.
6.
Decision-Making
Support – Computers analyze data quickly to
help in research, business, and technology.
Real-World Applications of Computers
