The physical component of a computer system is called "hardware". Hardware refers to all the physical parts of a computer that you can see and touch, such as the monitor, keyboard, mouse, central processing unit (CPU), motherboard, memory (RAM), graphics card, power supply, and so on.
Hardware is essential for a computer to function properly. Without hardware, a computer would not be able to process data or run software programs. The hardware components of a computer work together to perform tasks, store data, and display information on the screen.
Hard disk and floppy disk are examples of storage devices, which are also part of the hardware. The hard disk is a permanent storage device that stores all your files, programs, and operating system. The floppy disk is a removable storage device that was commonly used in the past to transfer files between computers.
In summary, the hardware is the physical part of a computer system that includes all the components that make up a computer, including storage devices like the hard disk and floppy disk.
