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.

Network Glossary Definition

The network glossary contains a complete list of network, computer-related and technical terms in alphabetic order, explanations and definitions for them, among them there are words well known for you and also specific, rare-used, uncommon or newly introduced terms. This specialized glossary, also known as a vocabulary, is the best in its field and covers in details the various aspects of computer network technologies. This glossary was developed by specialists using the practical experience and many useful sources to help the ConceptDraw users in their work, you can read and learn it from the screen on-line or print, it can be also used as a perfect educational guide or tutorial. ConceptDraw DIAGRAM software extended with Computer and Networks solution is easy to draw various types of Network diagrams, Network topology diagrams, Computer networking schematics, Network maps, Cisco network topology, Computer network architecture, Wireless networks, Vehicular networks, Rack diagrams, Logical, Physical, Cable networks, etc. Desktop ConceptDraw DIAGRAM Software is a good Visio for Mac Os X replacement. It gives you rich productivity and quality of the produced diagrams.

How to Draw a Computer Network

Network wiring cable. Computer and Network Examples

To connect two or more network devices are used the network cables. There are more different types of the network cables: Coaxial cable, Optical fiber cable, Twisted Pair, Ethernet crossover cable, Power lines and others. They are used depending of the network topology, size, protocol. This example was created in ConceptDraw DIAGRAM using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.

Network Topologies

Network topology is a topological structure of computer network, which can be physical or logical. The physical topology depicts location of different computer network elements such as computers, cables and other devices. The logical topology visually displays network dataflows from one device to another. Sometimes network logical and physical topologies can be the same. ConceptDraw DIAGRAM diagramming and vector drawing software is powerful for drawing network maps and network topologies diagrams of any kinds and complexity thanks to the Computer Network Diagrams solution from the Computer and Networks area. ConceptDraw STORE proposes collection of network icons libraries and a lot of Network Topology Diagram examples, samples and templates which were created at ConceptDraw DIAGRAM software specially for Computer Network Diagrams solution. There are six basic types of the network topologies: Bus, Star, Ring, Mesh, Tree, Fully Connected. You can fast and easy design professional-looking diagram for each of them using the ConceptDraw DIAGRAM tools. There are plenty of web Visio-like diagramming software available. Web based diagrams software can be powerful, but sometimes it is essential to have desktop software. One of the most advanced diagrams tools like Visio for Mac OS is ConceptDraw DIAGRAM app.

Rack diagrams - Vector stencils library

The vector stencils library "Rack diagrams" contains 33 rack design elements for drawing the computer network server rack diagrams.
"A 19-inch rack is a standardized frame or enclosure for mounting multiple equipment modules. Each module has a front panel that is 19 inches (482.6 mm) wide, including edges or ears that protrude on each side which allow the module to be fastened to the rack frame with screws. ...
Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack mounted system, a rack mount chassis, subrack, rack mountable, or occasionally simply shelf. The height of the electronic modules is also standardized as multiples of 1.75 inches (44.45 mm) or one rack unit or U (less commonly RU). The industry standard rack cabinet is 42U tall. ...
19-inch racks in 2-post or 4-post form hold most equipment in modern data centers, ISP facilities and professionally designed corporate server rooms. They allow for dense hardware configurations without occupying excessive floorspace or requiring shelving." [19-inch rack. Wikipedia]

Cisco Network Topology. Cisco icons, shapes, stencils and symbols

Cisco Network Topology represents the arrangement of worldwide recognized and standardized Cisco network symbols, icons, shapes, and stencils which help visualize the schemes of computer networks. Any equipment used in Cisco networks is also named a node and network topology diagram represents the scheme of connection the used nodes. Cisco Network Diagram illustrates how the signals enter on the networked devices and how the data spread within a network from one device to another. These diagrams are useful for engineers while constructing computer networks and working with them. Cisco Network Diagrams solution included to Computer and Networks area of ConceptDraw Solution Park contains quick-start templates, professionally designed samples and examples, and numerous libraries with a lot of predesigned vector design elements, icons, and shapes of Cisco equipment, components, devices, links which provide for ConceptDraw DIAGRAM users a perfect possibility of simple and quick drawing Cisco Network Diagrams and Schematics, Network Designs and Maps of any complexity.

Rack diagram template

Server rack diagrams visualize the the rack mounting of computer and network equipment as the drawing of frontal view of the rack with equipment installed. They are used for choosing the equipment or racks to buy, and help to organize equipment on the racks virtually, without the real installation.
"A 19-inch rack is a standardized frame or enclosure for mounting multiple equipment modules. Each module has a front panel that is 19 inches (482.6 mm) wide, including edges or ears that protrude on each side which allow the module to be fastened to the rack frame with screws." [19-inch rack. Wikipedia]
"A rack unit, U or RU is a unit of measure that describes the height of equipment designed to mount in a 19-inch rack or a 23-inch rack. The 19-inch (482.6 mm) or 23-inch (584.2 mm) dimension refers to the width of the equipment mounting frame in the rack including the frame; the width of the equipment that can be mounted inside the rack is less. One rack unit is 1.75 inches (4.445 cm) high.
The size of a piece of rack-mounted equipment is frequently described as a number in "U". For example, one rack unit is often referred to as "1U", 2 rack units as "2U" and so on.
A typical full size rack is 42U, which means it holds just over 6 feet of equipment, and a typical "half-height" rack would be 18-22U, or around 3 feet high." [Rack unit. Wikipedia]
