Point to Point 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.
Example 1. Point to Point Network Topology
This sample shows the Point-to-point network topology.
Network topology is the topological structure of the computer network.
Point-to-point network topology is a simple topology that displays the network of exactly two hosts (computers, servers, switches or routers) connected with a cable. Point-to-point topology is widely used in the computer networking and computer architecture. It is also used in the telecommunications systems when we speak about the communication connection of two nodes or endpoints.
Using the predesigned objects, templates and samples of the Computer and Networks Solution for ConceptDraw DIAGRAM you can create your own professional Computer Network Diagrams quick and easy.
The Computer Network Diagrams produced with ConceptDraw DIAGRAM are vector graphic documents and are available for reviewing, modifying, and converting to a variety of formats (image, HTML, PDF file, MS PowerPoint Presentation, Adobe Flash or MS Visio).

The Internet Connectivity of the computers, mobile devices, computer networks to the Internet enables the users to access the various Internet services. There are many ways and technologies of the connection to the Internet with different data signaling rates: Wireless, Ethernet cable, Optical fiber, Dial-up, DSL, broadband Internet access, etc.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park and shows how the customers connect to ISPs and ISPs connect between the tiers (peering and transit).

Network Topology Diagrams visualize the telecommunication and computer network topology and layout. They display the arrangement of the various elements of the computer network and how they communicate.
This sample shows the network topology diagram of the devices connection to the Internet. It was designed in ConceptDraw DIAGRAM using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park.

Today, we can’t imagine our lives without daily data exchange. To call a set of devices that can be connected with each other a computer network, we must be sure that these devices support appropriate protocols to transfer data. A network consisting of personal devices is private, and global computer networks, for example, Internet, connects network nodes worldwide.
This diagram represents a computer telecommunication network. The network depicted on the current diagram is featured with networked communication devices that provide data exchange through Internet. The network interconnections and connections between Internet nodes are settled using the cable media and wireless media. The nodes are the network workstations (terminals). and host computers. This network diagram was drawn with ConceptDraw DIAGRAM and its Computer and Networks Diagrams solution.

A database is a data collection, structured into some conceptual model. Two most common approaches of developing data models are UML diagrams and ER-model diagrams. There are several notations of entity-relationship diagram symbols and their meaning is slightly different. Crow’s Foot notation is quite descriptive and easy to understand, meanwhile, the Chen notation is great for conceptual modeling.
An entity relationship diagrams look very simple to a flowcharts. The main difference is the symbols provided by specific ERD notations. There are several models applied in entity-relationship diagrams: conceptual, logical and physical. Creating an entity relationship diagram requires using a specific notation. There are five main components of common ERD notations: Entities, Actions, Attributes, Cardinality and Connections. The two of notations most widely used for creating ERD are Chen notation and Crow foot notation. By the way, the Crow foot notation originates from the Chen notation - it is an adapted version of the Chen notation.

All computer networks differ by various params, and their size is one of them. As global area networks are the biggest, personal area (PAN) networks are the smallest. Personal computers, smartphones and other devices that have possibility to connect to Internet form a personal network.
This diagram was created using ConceptDraw Computer Network Diagrams to represent a typical components of Personal area network. A personal area network (PAN) is the connection of IT devices around an individual person. This sample of personal area network involves a notebook, a personal digital assistant (PDA), and a portable printer. Commonly a PAN contains such wireless devices as mouse, keyboard, smartphone and tablet. A wireless connection is typical for a PAN.

A Virtual network is a computer network that consists of virtual network links, i.e. between the computing devices there isn't a physical connection.
Well known forms of network virtualization are virtual networks based on the virtual devices (for example the network based on the virtual devices inside a hypervisor), protocol-based virtual networks (VLAN, VPN, VPLS, Virtual Wireless network, etc.) and their combinations.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Virtual network.
