what is computer
A computer is an electronic device that processes, stores, and executes instructions to perform tasks. It’s a programmable system that can take input, manipulate it according to a set of instructions (software), and then output the results.
Here’s a more detailed breakdown:
Key Components and Functionality:
- Input:Computers receive data and instructions from various sources like keyboards, mice, sensors, or even from other storage devices.
- Processing:The central processing unit (CPU) is the “brain” of the computer, responsible for executing instructions and performing calculations.
- Storage:Computers store data and instructions, both temporarily (RAM) and permanently (HDD/SSD or other storage devices).
- Output:Computers display results, often on a screen, or print output using a printer.
