Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering . To make the drawings easier to understand, people use familiar symbols, perspectives, units of ...
Computer architecture. Block diagram of a basic computer with uniprocessor CPU. Black lines indicate control flow, whereas red lines indicate data flow. Arrows indicate the direction of flow. In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [ 1]
Example of a Structured Chart. [ 1] A structure chart (SC) in software engineering and organizational theory is a chart which shows the breakdown of a system to its lowest manageable levels. [ 2] They are used in structured programming to arrange program modules into a tree. Each module is represented by a box, which contains the module's name.
Because computer parts contain hazardous materials, there is a growing movement to recycle old and outdated parts. [66] Computer hardware contain dangerous chemicals such as lead, mercury, nickel, and cadmium. According to the EPA these e-wastes have a harmful effect on the environment unless they are disposed of properly.
The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [ 1] The document describes a design architecture for an electronic digital computer with these components: The ...
v. t. e. An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing. Usually, a number of drawings are necessary to completely specify even a simple component.
A functional block diagram, in systems engineering and software engineering, is a block diagram that describes the functions and interrelationships of a system. The functional block diagram can picture: [ 1] functions of a system pictured by blocks. input and output elements of a block pictured with lines.
A functional flow block diagram ( FFBD) is a multi-tier, time-sequenced, step-by-step flow diagram of a system 's functional flow. [ 2] The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ambiguous. Here, "functional flow" pertains to the ...
