A computer works by executing a series of instructions stored in its memory. These instructions are processed by the computer's central processing unit (CPU), which is responsible for carrying out calculations and logical operations. The CPU communicates with other components of the computer, such as the memory, storage devices, and input/output devices, to perform tasks and run programs.
When a user interacts with a computer, input devices such as a keyboard or mouse are used to input data and commands. The computer processes this input and displays the results on the screen using output devices such as a monitor or printer.
In summary, a computer works by processing instructions, inputting and outputting data, and communicating with its various components to perform tasks and run programs.

How Computers Do Their Work
1. Fetching and Decoding: Control Unit
- The control unit retrieves instructions from memory.
- It decodes the instructions, identifying the operations to be performed.
2. Executing Instructions: Arithmetic Logic Unit (ALU)
- The ALU performs the specified operations, such as addition, subtraction, multiplication, and logical operations.
- It processes data and stores the results in registers.
3. Loading and Storing Data: Memory
- Memory holds instructions, data, and temporary results.
- The CPU can access and modify memory as needed.
4. Input and Output (I/O): Input/Output Devices
- Input devices (e.g., keyboard, mouse) allow users to provide input.
- Output devices (e.g., monitor, printer) display or print the results.
- I/O devices communicate with the CPU through input/output ports.
5. Communication: Buses
- Buses are high-speed communication pathways that connect the various components of the computer (e.g., CPU, memory, I/O devices).
- They allow for data and instruction transfer between components.
6. Executing Program Instructions Sequentially:
- The computer executes program instructions one after the other in sequence.
- Each instruction causes the computer to perform a specific action.
7. Making Decisions: Conditional Statements
- Conditional statements allow the computer to make decisions based on conditions (e.g., if, else, while).
- This enables branching to different parts of the program based on inputs or calculations.
8. Looping and Iteration:
- Looping statements allow the computer to repeat certain sections of code multiple times.
- This is useful for tasks that require repetitive operations.
9. Subroutines and Functions:
- Subroutines or functions are reusable code blocks that can be called from multiple parts of the program.
- They help to modularize and organize code.
10. Continuous Process:
- The computer continuously repeats this process of fetching, decoding, executing, and communicating until the program is complete or an interruption occurs (e.g., user input).
