Computer hardware is the collection of physical components that make up a computer system. Computer hardware is the physical parts or components of a computer, such as monitor, keyboard, computer data storage, hard disk drive (HDD), graphics card, sound card, memory (RAM), motherboard , etc. Tangible physical objects. On the contrary, the software is instructions that can be stored and executed by hardware. The hardware is driven by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system.
The template for all modern computers is the architecture of Von Neumann, detailed in a paper from 1945 by the Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and a program counter, a storage memory Data and instructions, and the input and output mechanisms. The meaning of the term has evolved to mean a stored program computer in which an instruction capture and a data operation can not occur at the same time because they share a common bus. This is known as Von Neumann's bottleneck and often limits system performance.
