 What Is Computer Hardware

Computer hardware is a collective term used to describe any of the physical components of an analog or digital computer. The term hardware distinguishes the tangible aspects of a computing device from software, which consists of written instructions that tell physical components what to do. Computer hardware can be categorized as having either internal or external components. Internal components include items such as the motherboard, central processing unit (CPU), random access memory (RAM), hard drive, optical drive, heat sink, power supply, transistors, chips, graphics processing unit (GPU), and network interface card (NIC).  Theses components collectively process or store the instructions delivered by the program or operating system (OS).
