The component diagram extends the information given in a component notation element. One way of illustrating a component's provided and required interfaces is through a rectangular compartment attached to the component element. [3] Another accepted way of presenting the interfaces is the ball-and-socket graphic convention.
The block diagram can use additional schematic symbols to show particular properties. Since the late 1950s, functional block diagrams have been used in a wide range applications, from systems engineering to software engineering. They became a necessity in complex systems design to "understand thoroughly from exterior design the operation of the ...
A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .
For example, a component television system is a monitor, tuner and speakers sold separately and which can be integrated into a single system. The component television form factor began in 1980 (but became notable in 1982) with Sony 's ProFeel television line and became a design fad with many manufacturers until the late 1980s.
Figure 1: Functional flow block diagram format. [1] 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 ...
Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.
Demonstration of a 30-channel cable TV system in the Netherlands in March 1981. The very first cable networks were operated locally, notably in 1936 by Rediffusion in London in the United Kingdom [ 5 ] and the same year in Berlin in Germany, notably for the Olympic Games , and from 1948 onwards in the United States and Switzerland.
