In computing, hardware refers to the physical components of a computer system that are used to perform various functions. These components include the central processing unit (CPU), memory, storage devices, input/output devices, and other peripherals.
- The CPU, also known as the “brain” of the computer, is responsible for executing instructions and performing calculations. It is typically made up of one or more cores, which are the units that process the data.
- Memory, also known as RAM (Random Access Memory), is a type of computer data storage that stores instructions and data that the CPU can quickly access.
- Storage devices such as hard drives, solid-state drives (SSD) and USB drives, store data and files that can be retrieved by the computer and user later.
- Input/output devices include the keyboard, mouse, monitor, and other devices that are used to interact with the computer.
- Peripherals are additional devices that can be connected to a computer to enhance its functionality, such as printers, scanners, cameras, and external hard drives.
Together, these hardware components work together to allow a computer to perform various functions, from running software programs to displaying images on a screen to storing data. The hardware components also interact with software, which refers to the programs and operating systems that run on a computer and direct the hardware to perform various tasks.
