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 .
DeKalb–Peachtree Airport (IATA: PDK, ICAO: KPDK, FAA LID: PDK) is a county-owned, public-use airport in DeKalb County, Georgia, United States. [1] The airport is located in the city of Chamblee, just northeast of Atlanta. It operates 24 hours per day, although it is uncontrolled from 11:00 PM EST to 6:30 AM EST (Monday through Friday) or 7:00 ...
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.
Use the text button to add text to your diagram. The next 9 buttons are used to add shapes and lines to the diagram. Experiment with them: they are pretty much self explanatory. Below is a drop down list that allows you to choose from several groups of special objects that can be used in your diagram.
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.
These tools have capabilities in common with drawing tools and network monitoring tools. They are more specialized than general drawing tools and provide network engineers and IT systems administrators a higher level of automation and the ability to develop more detailed network topologies and diagrams.
The structure chart is similar in appearance to an organizational chart, but has been modified to show additional detail. Structure charts can be used to display several types of information, but are used most commonly to diagram either data structures or code structures. [3]
A state diagram is used in computer science and related fields to describe the behavior of systems. State diagrams require that the system is composed of a finite number of states . Sometimes, this is indeed the case, while at other times this is a reasonable abstraction .
