The hardware is the tangible components of a computer system that you can use to input and output information. The main components of a computer system are hardware and software. The hardware is controlled by computer software which consists of a set of program instructions that collaborates with hardware to perform an action.

Computer hardware differs based on the type of computing system. A typical desktop computer consists of hardware such as the monitor, keyboard, mouse and computer case which houses other internal hardware components such as motherboard, central processing unit (CPU), data storage devices, graphic cards, disk drives. A laptop computer integrates all these parts into a portable compact device.

In addition to core components, a computer system can interface with external hardware devices such as printers, microphones, digital cameras, webcams, speakers, and USB flash drives for various tasks. Interestingly, modern technology allows for specialized software applications, like an option scanner, to analyze financial markets, demonstrating the versatile application of computing hardware in both traditional and innovative fields.

What are the categories of Hardware?

Hardware devices can be categorized into the following categories based on their functionality.

  1. Input devices – The devices that you can use to feed data into a computer to be processed by software applications. The typical examples of input devices are a mouse, keyboard, touchpad, touch screen, scanner, and webcam.
  2. Output devices – The devices that convert processed data into a human-readable form such as audio, videos, text, and graphics. The computer monitor, printer, and speakers are examples of output devices.
  3. Processing devices – The devices that execute program instructions and process data accordingly. The CPU, GPU, and motherboard are examples of processing devices.
  4. Storage devices – These devices encompass tools used to store data for later retrieval through processing devices. These devices can be either internal or external, including hard disk drives (HDDs), solid-state drives (SSDs), random access memory (RAM), USB flash drives, external hard drives, and NVMe (Non-Volatile Memory Express) storage.
