What is hardware in a computer system?
Hardware consists of the physical electrical components within a computer that manipulate information flow.
This includes a processor (CPU), physical memory (RAM), hard disk drives, CD/DVD drives, flash memory card readers, sound cards, video cards, network adapter cards, ports, and mainboards.
What is software in a computer system?
Software refers to sets of instructions or programs that allow hardware components to manipulate data.
It includes programs that are stored on hardware media and loaded into computer hardware like memory and processor. After execution, a program becomes a process.
What’s the difference between a program and a process?
A program is a file stored on a computer, while a process is that file in action, performing a task.
When a program is executed, it becomes a process that uses hardware resources to accomplish its task.
What are applications (apps) in computing?
Applications are programs designed for specific uses and interactions.
An example would be a word processor, computer games, graphical manipulation programs, and system utilities. They are commonly used by individuals.
What is operating system (OS) software?
Operating system (OS) software is a set of components that control computer hardware.
It’s essential for the computer’s functioning. It loads into hardware and manages other application software. Without an OS, the computer wouldn’t be usable.
What’s the role of the operating system after turning on the computer?
After turning on the computer, the operating system loads into computer hardware.
It then centrally controls all other application software, allowing users to interact with applications and perform tasks.
