The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
On a circuit diagram, the symbols for components are labelled with a descriptor or reference designator matching that on the list of parts. For example, C1 is the first capacitor, L1 is the first inductor, Q1 is the first transistor, and R1 is the first resistor. Often the value or type designation of the component is given on the diagram ...
Inside a gaming case during gameplay. 360° photograph. A full tower case. Accessories shown include: a fan controller, a DVD burner, and a USB memory card reader.. Cases can come in many different sizes and shapes, which are usually determined by the form factor of the motherboard since it is physically the largest hardware component in most computers. Consequently, personal computer form ...
The Harvard architecture is a computer architecture with separate storage [1] and signal pathways for instructions and data. It is often contrasted with the von Neumann architecture, where program instructions and data share the same memory and pathways. This architecture is often used in real-time processing or low-power applications. [2] [3]
The inside of a white box computer. In computer hardware, a white box is a personal computer or server without a well-known brand name. [1]The term is usually applied to systems assembled by small system integrators and to homebuilt computer systems assembled by end users from parts purchased separately at retail.
Dell Precision T3600 System Motherboard, used in professional CAD Workstations. Manufactured in 2012. A motherboard (also called mainboard, main circuit board, MB, base board, system board, or, in Apple computers, logic board) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems.

The in-circuit test may also exercise boundary scan test features of some components. In-circuit test systems may also be used to program nonvolatile memory components on the board. In boundary scan testing, test circuits integrated into various ICs on the board form temporary connections between the PCB traces to test that the ICs are mounted ...
