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 Security

The Internet is a giant computer network which connects computers all over the world. It is integral part of human society and business. But the serious question for network engineers, designers, lawmakers and enforcers is the need for protect the Internet networks from the Internet crimes, hacking and attacks. There are quite a number of hardware, software and physical methods of protection against them. The samples you see on this page were created in ConceptDraw DIAGRAM using the tools of Network Security Diagrams Solution for ConceptDraw DIAGRAM software. They show protection networks with Firewalls and other network security devices.

Hierarchical Network Topology

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park. This sample shows the Hierarchical network topology. A Hierarchical network topology interconnects multiple groups that are located on the separate layers to form a larger network. Each layer concentrates on the specified functions, this allows to choose the right equipment for the layer.

Ring Network Topology

The Ring Network Topology Diagram examples was created using ConceptDraw DIAGRAM software with Computer and Networks solution.

Storage area networks (SAN). Computer and Network Examples

A Storage area network (SAN) is a dedicated network that provides access to data storage and operations only on the block level. SAN usually has own network of storage devices/elements and disk arrays that are connected with each other and to a remote data-sharing network. SANs are widely used for enhancing the storage devices (optical jukeboxes, disk arrays, tape libraries) that are accessible for networked servers. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park. It shows the hybrid of Storage area network (SAN) and Network Attached Storage (NAS) technologies.

Network Topology Mapper

Network Topology in communication networks, a topology is a usually schematic description of the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical topology. Network Topology Mapper offers extensive drawing tools professional-looking network diagrams quickly and easily allowing you to clearly represent and communicate network architecture, topology, and design to engineers, stakeholders and end-users.
"Logical topology, or signal topology, is the arrangement of devices on a computer network and how they communicate with one another. How devices are connected to the network through the actual cables that transmit data, or the physical structure of the network, is called the physical topology. Physical topology defines how the systems are physically connected. It represents the physical layout of the devices on the network. The logical topology defines how the systems communicate across the physical topologies.
Logical topologies are bound to network protocols and describe how data is moved across the network. ...
EXAMPLE : twisted pair Ethernet is a logical bus topology in a physical star topology layout. while IBM's token ring is a logical ring topology, it is physically set up in star topology." [Logical topology. Wikipedia]
This Cisco logical computer network diagram example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

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.

"A bus network is a network topology in which nodes are connected in a daisy chain by a linear sequence of buses. ...
The bus is the data link in a bus network. The bus can only transmit data in one direction, and if any network segment is severed, all network transmission ceases.

A host on a bus network is called a station or workstation. In a bus network, every station receives all network traffic, and the traffic generated by each station has equal transmission priority. Each network segment is, therefore, a collision domain. In order for nodes to transmit on the same cable simultaneously, they use a media access control technology such as carrier sense multiple access (CSMA) or a bus master." [Bus network. Wikipedia]
