Hardware :

🔹️A computer is a machine that can be programmed to accept data (input), and process it into useful information (output).

🔹️It also stores data for later reuse (storage). The processing is performed by the hardware.

🔹️The computer hardware responsible for computing are mainly classified as follows:

🌟Input device
🌟Main memory
🌟Secondary memory
🌟Output devices

Input devices allows the user to enter the program and data and send it to the processing unit. The common input devices are keyboard, mouse and scanners.

The processor ,more formally known as thr central processing unit (CPU), has the electronic circuitry that manipulates input data into the information as required. The central processing unit actually executes computer instructions.

Memory from which the CPU fetches the instructions and data is called main memory. It is also called as primary memory and is volatile in nature.

Output devices show the processed data – information – thr result of processing. The devices are normally a monitor and printers.

Storage usually means secondary storage, which stores data and programs. Here the data and programs are permanently stored for future use.

The hardware devices attached to the computer are called peripheral equipment. Peripheral equipment includes all input, output and secondary storage devices.
