Computer hardware. PDP-11 CPU board. Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a monitor, mouse, keyboard, and speakers. [ 1][ 2]
The second-generation computer architectures initially varied; they included character-based decimal computers, sign-magnitude decimal computers with a 10-digit word, sign-magnitude binary computers, and ones' complement binary computers, although Philco, RCA, and Honeywell, for example, had some computers that were character-based binary ...
An output device is any piece of computer hardware that converts information or data into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video. Examples include monitors, printers, speakers, headphones, projectors, GPS ...

NodeMCU – Wi-Fi microcontroller board. Novena – an ARM based computer built by Andrew Huang and associates. OpenPOWER – Power ISA, an open ...
The most common set of requirements defined by any operating system or software application is the physical computer resources, also known as hardware, A hardware requirements list is often accompanied by a hardware compatibility list (HCL), especially in case of operating systems.
Personal computer. An artist's depiction of a 2000s-era desktop-style personal computer, which includes a metal case with the computing components, a display and a keyboard ( mouse not shown) A personal computer, often referred to as a PC, is a computer designed for individual use. [ 1] It is typically used for tasks such as word processing ...
v. t. e. The history of computing hardware covers the developments from early simple devices to aid calculation to modern day computers . The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic operation, then manipulate the device to obtain the result.
A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing [1] data from, a computer or a computing system. [2] Most early computers only had a front panel to input or display bits and had to be connected to a terminal to print or input text through a keyboard.
