computer is an electronic device that receives data (input), processes it using a set of instructions (software), and produces a result (output). It can also store data and perform a wide range of tasks, from simple calculations to complex operations. Computers consist of physical components called hardware, such as the CPU and monitor, and non-physical instructions called software, like the operating system and applications.
Key components
Hardware:
The physical parts you can touch, such as the motherboard, processor (CPU), memory, hard drive, monitor, and keyboard.
Software:
The programs and instructions that tell the hardware what to do. This includes the operating system (like Windows or macOS) and all applications, such as word processors or games.
How it works
Input:
The computer receives data through input devices like a keyboard or mouse.
Processing:
The CPU takes this data and performs calculations or other operations based on the instructions from the software.
Storage:
It stores data and programs in memory (like RAM) or on storage devices (like a hard drive).
Output:
The final results are displayed or sent to an output device, such as a monitor or printer.
