Fully Connected Network Topology Diagram

Network Topology - Fully Connected
Fully Connected Network Topology (Complete topology, Full mesh topology) is a network topology characterized by existence of direct links between all pairs of nodes. The Fully connected network including n nodes, contains n(n-1)/2 direct links. This topology is mostly used in military applications. It is a quite expensive network technology and is extremely impractical for the large networks. But when it is set, it provides a high degree of reliability thanks to the large quantity of redundant links between nodes and so multiplicity of paths for the data. The two-node network is also considered as a Fully connected network. Computer Network Diagrams solution from Computer and Networks area of ConceptDraw Solution Park offers the predesigned vector stencils libraries, examples and templates for easy designing various Computer network topology diagrams for wired and wireless networks, including the Fully connected topology. This solution is intended to help computer network designers and engineers perfectly illustrate network documentation, reports, presentations, etc.

ConceptDraw PRO ER Diagram Tool

ER Diagram Tool. Chen ERD
Entity-relationship model, also called ER-model, is the main tool of domain modeling on the stage of conceptual design. The modeling of domain data structures is based on the use of graphical tools - Entity-Relationship diagrams (ER-diagrams). The core concepts of ER-Diagram are entity, attribute and relationship. ER-diagram lets visually represent the entities, helps effectively document all properties of designed system and to detail the data storages. To represent the elements at ER-model are commonly used Chen’s notation and Crow’s foot notation, each has its pros and cons. The entity on ER-diagram is represented in the form of rectangle, which specifies its name. An attribute is a property of the entity and relationship is an interaction between the entities. The relationship between two entities is called binary, between more than two entities - ternary. Specific software, such as ConceptDraw PRO with Entity-Relationship Diagram (ERD) solution from ConceptDraw Solution Park is helpful for easy creation Entity-Relationship Diagrams.

How To use Building Plan Examples

ConceptDraw Building Plans Solution Examples
The Building plans of different types, Floor plans, Layout schemes which are necessary and obligatory for construction various types of buildings, are designed by architects and building engineers. It is very desirable the availability of special auxiliary software for professional representation them. Exactly such software is a ConceptDraw PRO extended with numerous solutions from the Building Plans area. How to make a Building plan with ConceptDraw PRO? The good foundation is collection of predesigned Building Plan examples and samples, including Architectural house plans, House floor plans, Residential building plans, Pole building plans, Storage building plans, Commercial building plans, Office floor plans, Office layout plans, Restaurant building plans, Salon floor plan, Electrical layout plans, Fire and Emergency plans, Site plans, Plans of building services, Furniture and Equipment layouts, and many others. Simply select desired and the most suitable example and make your own perspective plan or professional design proposal on its base.

Tree Network Topology Diagram

Tree Network Topology
A Tree network topology (Hierarchical topology) is a hybrid network topology that contains the combination of two or more star networks connected via bus networks. Each star network is a LAN (local area network) with central computer or server and workstation nodes connected to it. The central computers of star networks are connected to a main cable that is called a bus. Each node of the Tree network can have an arbitrary number of child nodes, you can easy add/remove the separate workstations and even the whole star networks, the failure of one workstation will not affect the work of others. This topology is ideal solution when workstations are located in groups within a small physical region, rarely is used in WAN configurations. Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park contains templates, samples and numerous libraries of predesigned vector stencils of computer network devices and equipment, which can be effectively used for designing various network topologies diagrams, including Tree Network Topology.
Design elements - Zodiac constellations
The vector stencils library "Zodiac constellations" contains 12 star constellation charts.
"In Western astrology, astrological signs are the twelve 30º sectors of the ecliptic, starting at the vernal equinox (one of the intersections of the ecliptic with the celestial equator), also known as the First Point of Aries. The order of the astrological signs is Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces." [Astrological sign. Wikipedia]
"Constellations.
The zodiacal signs are distinct from the constellations associated with them, not only because of their drifting apart due to the precession of equinoxes but also because the physical constellations take up varying widths of the ecliptic, so the sun is not in each constellation for the same amount of time. Thus, Virgo takes up five times as much ecliptic longitude as Scorpius. The zodiacal signs are an abstraction from the physical constellations, and each represent exactly one twelfth of the full circle, or the longitude traversed by the Sun in about 30.4 days.
Some "parazodiacal" constellations are also touched by the paths of the planets. The MUL.APIN lists Orion, Perseus, Auriga, and Andromeda. Furthermore, there are a number of constellations mythologically associated with the zodiacal ones : Piscis Austrinus, The Southern Fish, is attached to Aquarius. In classical maps, it swallows the stream poured out of Aquarius' pitcher, but perhaps it formerly just swam in it. Aquila, The Eagle, was possibly associated with the zodiac by virtue of its main star, Altair. Hydra in the Early Bronze Age marked the celestial equator and was associated with Leo, which is shown standing on the serpent on the Dendera zodiac. Corvus is the Crow or Raven mysteriously perched on the tail of Hydra.
Due to the constellation boundaries being redefined in 1930 by the International Astronomical Union, the path of the ecliptic now officially passes through thirteen constellations: the twelve traditional 'zodiac constellations' plus Ophiuchus, the bottom part of which interjects between Scorpio and Sagittarius. Ophiuchus is an anciently recognized constellation, catalogued along with many others in Ptolemy's Almagest, but not historically referred to as a zodiac constellation. The inaccurate description of Ophiuchus as a sign of the zodiac drew media attention in 1995, when the BBC Nine O'Clock News reported that "an extra sign of the zodiac has been announced by the Royal Astronomical Society". There had been no such announcement, and the report had merely sensationalized the 67-year-old 'news' of the IAU's decision to alter the number of designated ecliptic constellations." [Zodiac. Wikipedia]
The star maps example "Design elements - Zodiac constellations" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Astronomy solution from the Science and Education area of ConceptDraw Solution Park.
