Star Network Topology

The Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park provides examples, templates and vector stencils library with symbols of local area network (LAN) and wireless LAN (WLAN) equipment.
Use it to draw the physical and logical network topology diagrams for wired and wireless computer communication networks.

Bus Network Topology

The Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park provides examples, templates and vector stencils library with symbols of local area network (LAN) and wireless LAN (WLAN) equipment.
Use it to draw the physical and logical network topology diagrams for wired and wireless computer communication networks.
Create your bus network topology diagrams using the ConceptDraw DIAGRAM.

Hybrid 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 is example of the Hybrid network topology.
Network topology is the topological structure of the computer network. There are many types of the network topologies: bus, star, ring, mesh topology, but the most popular is the hybrid topology.

Personal area (PAN) networks. Computer and Network Examples

A Personal area network (PAN) is a computer network that is used for data transmission between different personal devices (computers, telephones, digital devices, etc.) and for connecting to the higher level network and Internet. PANs can be wired with computer buses (USB and FireWire). A wireless personal area network (WPAN) can be made using the network technologies such as Bluetooth, IrDa, UWB, Z-Wave, ZigBee, Body Area Network. A personal area network handles the interconnection of IT devices at the surrounding of a single user. Generally, PAN contains from following such appliances: cordless mice and keyboards, cordless phone, Bluetooth handsets.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Personal area network.

Wireless Network Topology

Wireless network topology — logical topology.
Wireless network topology shows how the computers connect each other when there is no physical connection. The computers communicate each using the wireless devices.

WLAN

ConceptDraw DIAGRAM diagramming and vector drawing software extended with Wireless Networks Solution gives the ability to its users to create professional looking WLAN schemes and diagrams quick and easy.

Ring Network Topology

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

Overlay networks. Computer and Network Examples

An Overlay network is a computer network that is built on the top of another network. The nodes of the overlay network are connected by virtual or logical links.
Overlay networks are widely used in telecommunication. They also allow to improve Internet routing.
Using the solutions of the Computer and Networks Area for ConceptDraw DIAGRAM with wide set of ready-to-use predesigned vector stencils and examples you can design anyone overlay networks quick and easy.

Cisco Network Templates

Cisco has a huge number of enterprise clients in the corporate environment. Therefore many network engineers should draw network diagrams for Cisco hardware.
ConceptDraw has Cisco network diagram templates:

Wireless Mesh Network, Network Organization Chart, Roaming Wireless Local Area Network, Cisco ISG Topology Diagram, Cisco Express Forwarding Sample that facilitates drawing at the initial stage.

However for customizing Cisco network diagrams you can use 13 Libraries like this: Cisco Basic, Cisco Buildings, Cisco IBM, Cisco LAN, Cisco WAN, Cisco Media, Cisco Optical, Cisco People, Cisco Routers, Cisco Security, Cisco Switches&Hub, Cisco Telepresences, etc.

This take great advantage to you for designing Cisco network diagram templates.

ERD Symbols and Meanings

Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw DIAGRAM.
