Computer Hardware encompasses the physical components and peripherals that make up a computer system. These elements are tangible, unlike software which is intangible. Computer hardware can be categorized into two main types: internal and external. Internal hardware includes the motherboard, processor (CPU), memory (RAM), storage devices such as hard drives or solid-state drives (SSDs), graphics cards, power supply, and cooling systems. External hardware refers to peripherals that connect to the computer, such as monitors, keyboards, mice, printers, scanners, speakers, microphones, webcams, and network components like routers and switches. The term "Electronics" is broad and encompasses all electrical devices, including computers and computer hardware. Computer Accessories are additional components that enhance the functionality or usability of a computer system, such as ergonomic keyboards, gaming peripherals, or specialized input devices like drawing tablets. Mouse Pads, specifically Silicone Mouse Pads, fall under the category of computer accessories designed to improve user comfort and reduce wear on mouse feet. The silicone material provides a smooth, consistent surface for the mouse to glide on, while also protecting the underlying desk or table surface from scratches and spills. In summary, Computer Hardware represents the physical components of a computer system, including internal and external elements, electronics, computer accessories, and specialized peripherals like mouse pads. The category is characterized by tangible, functional devices that enable computing and related tasks through electronic signal processing and user interaction.
