Computer General Knowledge Q&A: 5000+ Essential Questions & Answers
A Short Note on General Computer
Knowledge
General computer knowledge covers the fundamental concepts
of how computers work, from their physical components to the software and
networks that make them useful. At its core, it's about understanding the
relationship between hardware (the physical parts like the
CPU, RAM, and hard drive) and software (the programs and data
that run on the hardware).
Understanding these basics is essential in today's digital
world. It includes knowing the roles of the Central Processing
Unit (CPU), which acts as the computer's "brain," and Random
Access Memory (RAM), which is used for temporary data storage. It also
involves grasping the function of an operating system (OS), such as
Windows or macOS, which manages all the computer's resources and provides a
user interface.
Beyond the device itself, general computer knowledge extends
to networking and the internet. This includes understanding
concepts like IP addresses, routers, and protocols such
as HTTP and HTTPS, which are the rules that govern
communication online. Crucially, it also encompasses cybersecurity,
which is the practice of protecting systems and data from threats like malware and phishing.
