Schematic. Photomicrograph of the human chromosomes. Schematic diagram of the same. A schematic, or schematic diagram, is a designed representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the key information the schematic is ...
A mechanical watch is a watch that uses a clockwork mechanism to measure the passage of time, as opposed to quartz watches which function using the vibration modes of a piezoelectric quartz tuning fork, or radio watches, which are quartz watches synchronized to an atomic clock via radio waves. A mechanical watch is driven by a mainspring which ...
Value-stream mapping, also known as material- and information-flow mapping, [ 1] is a lean [ 2] -management method for analyzing the current state and designing a future state for the series of events that take a product or service from the beginning of the specific process until it reaches the customer. A value stream map is a visual [ 2] tool ...
Data-Flow Diagram example [19] A data-flow diagram (DFD) is a graphical representation of the "flow" of data through an information system. It differs from the flowchart as it shows the data flow instead of the control flow of the program. A data-flow diagram can also be used for the visualization of data processing (structured design).
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.

The Karnaugh map ( KM or K-map) is a method of simplifying Boolean algebra expressions. Maurice Karnaugh introduced it in 1953 [ 1][ 2] as a refinement of Edward W. Veitch 's 1952 Veitch chart, [ 3][ 4] which itself was a rediscovery of Allan Marquand 's 1881 logical diagram[ 5][ 6] aka Marquand diagram[ 4] but now with a focus set on its ...
