| File info: Computer hardware is the physical components of a computer, such as the case, the motherboard, the processor, the memory, the storage devices, and the input and output devices. The case is the outer shell of a computer that protects the internal components. It is typically made of metal or plastic. The motherboard is the main circuit board of a computer. It connects all of the other components of the computer together. The processor is the brain of a computer. It is responsible for interpreting and executing instructions. The memory of a computer is where the instructions and data are stored. There are two main types of memory: random access memory (RAM) and read-only memory (ROM). RAM is temporary memory that is used to store the instructions and data that the computer is currently using. ROM is permanent memory that stores the computer's operating system and other essential programs. Storage devices are used to store data permanently. There are two main types of storage devices: magnetic storage devices and optical storage devices. Magnetic storage devices store data on a magnetic surface. Examples of magnetic storage devices include hard drives and floppy disks. Optical storage devices store data on a reflective surface. Examples of optical storage devices include CDs, DVDs, and Blu-ray discs. Input devices are used to enter data into a computer. Examples of input devices include keyboards, mice, and scanners. Output devices are used to display information from a computer. Examples of output devices include monitors, printers, and speakers. Computer hardware is essential for the operation of a computer. It provides the physical components that allow the computer to process information, store data, and communicate with the user. | ||
