Computers work by executing a series of instructions in a specific order to perform tasks. These instructions are given to the computer in the form of a program or software.
At the core of a computer is the central processing unit (CPU), which is responsible for executing these instructions. The CPU consists of various components, including the arithmetic logic unit (ALU) and the control unit. The ALU performs mathematical and logical operations, while the control unit manages the flow of data and instructions within the CPU.
The computer's memory, also known as RAM (Random Access Memory), stores data and instructions that the CPU needs to access quickly. When a program is executed, the CPU fetches the necessary instructions from the memory and performs the required operations.
Input devices, such as keyboards and mice, allow users to provide data and instructions to the computer. The computer processes this input and produces output through devices like monitors or printers.
The computer's operating system (OS) manages the hardware and software resources of the computer. It provides a user interface and handles tasks such as memory management, file management, and device management.
In summary, computers work by executing instructions provided by software, using the CPU to process data and perform operations, and utilizing memory and input/output devices to interact with users and produce output.
