Hardware refers to the physical components of a computer system, such as the central processing unit, monitor, keyboard, and mouse. Software, on the other hand, refers to the programs and applications that run on the hardware and enable it to perform specific tasks.
Cloud computing is a technology that allows users to access and store data and applications over the internet instead of on their local computer or server. This enables users to access their information from anywhere with an internet connection and eliminates the need for physical storage devices.
An operating system is a software that manages computer hardware and provides a platform for running applications. It performs essential tasks such as managing memory, coordinating input and output devices, and providing a user interface for interacting with the computer.
A virus is a type of malware that replicates itself and spreads to other files on a computer, while malware is a broader term that encompasses any type of malicious software designed to disrupt, damage, or gain unauthorized access to a computer system.
