Star Network Topology

Star is a basic computer network topology in which all nodes (computers and peripheral devices) of the network are connected to the central hub or switch with a point-to-point connection, forming a physical network segment. Such network segment can function separately or as a part of complex network topology. The switch is a server, the peripherals are the clients. The large workload and functions of network management are entrusted on the central computer, all information exchange goes through it, so it must to be obligatory the most powerful. The star network topology is a simple topology for design and implementation. Its advantages are high performance, flexible administration capabilities, simplicity of adding additional nodes and search of faults, the fact that a failure of one workstation doesn't affect the work of entire network. But the failure of central hub will result the failure of whole network or network segment - it's the main disadvantage. Use the ConceptDraw DIAGRAM with Computer and Networks solution to designing Star Network Topology Diagrams fast and easy.

Entity Relationship Diagram Software Engineering

Entity Relationship Diagram (aka ER Diagram, E-R Diagram, ERD) is a time-tested and widespread software development and software engineering method for data modeling, illustrating the logical structure of databases and system design. For ERDs construction are used three basic elements: entities, attributes, and relationships. Chen's notation for ERD supposes the use of rectangles (boxes) to represent entities and diamonds to depict relationships between first-class objects. This notation is popular when creating conceptual data models of information systems. Another standardized notation for ER diagrams is Crow's foot notation. ConceptDraw DIAGRAM as a powerful Entity Relationship Diagram software engineering provides the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park for instantly describing databases using ERDs of Crow’s Foot and Chen’s notations. Use the predesigned vector elements for both these notations from 2 libraries included to Entity-Relationship Diagram (ERD) solution.

ERD Symbols and Meanings

Entity Relationship Diagram (ERD) is a popular software engineering tool for database modeling and illustration the logical structure of databases, which uses one of two notations - Chen's or Crow’s Foot. Crow's foot notation is effective when used in software engineering, information engineering, structured systems analysis and design. Each of these notations applies its own set of ERD symbols. Crow's foot diagrams use boxes to represent entities and lines between these boxes to show relationships. Varied shapes at the ends of lines depict the cardinality of a given relationship. Chen's ERD notation is more detailed way to represent entities and relationships. ConceptDraw DIAGRAM application enhanced with all-inclusive Entity-Relationship Diagram (ERD) solution allows design professional ER diagrams with Chen's or Crow’s Foot notation on your choice. It contains the full set of ready-to-use standardized ERD symbols and meanings helpful for quickly drawing, collection of predesigned ERD samples, examples and templates.

Venn Diagram Examples for Problem Solving. Computer Science. Chomsky Hierarchy

A Venn diagram, sometimes referred to as a set diagram, is a diagramming style used to show all the possible logical relations between a finite amount of sets. In mathematical terms, a set is a collection of distinct objects gathered together into a group, which can then itself be termed as a single object. Venn diagrams represent these objects on a page as circles or ellipses, and their placement in relation to each other describes the relationships between them. The Venn diagram example below visualizes the the class of language inclusions described by the Chomsky hierarchy.
