Virtual private networks (VPN). Computer and Network Examples

A Virtual Private Network (VPN) is a network that allows the private networks at a remote location securely connect to the public Internet and provide access only to the intended recipients for transmitting data. VPN is built by creating the virtual point-to-point connection using the dedicated connections, traffic encryption or virtual tunneling protocols. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Virtual Private Network (VPN) diagram.

Virtual networks. Computer and Network Examples

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.

Network Topologies

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.

Telecommunication networks. Computer and Network Examples

A Telecommunications network is a network of nodes, links, trunks and telephone switches that are connected, operated by telephone companies and realize telephone, audio, visual and data communications among the users. The telecommunications network can also include Internet, microwave, wireless equipment. This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Telecommunications network.

The vector stencils library "Cisco LAN" contains 23 symbols of local area network (LAN) devices and equipment for drawing Cisco LAN topology diagrams.
"Network topology describes the layout of interconnections between devices and network segments. At the Data Link Layer and Physical Layer, a wide variety of LAN topologies have been used, including ring, bus, mesh and star, but the most common LAN topology in use today is switched Ethernet. At the higher layers, the Internet Protocol (TCP/ IP) has become the standard, replacing NetBEUI, IPX/ SPX, AppleTalk and others.
Simple LANs generally consist of one or more switches. A switch can be connected to a router, cable modem, or ADSL modem for Internet access. Complex LANs are characterized by their use of redundant links with switches using the spanning tree protocol to prevent loops, their ability to manage differing traffic types via quality of service (QoS), and to segregate traffic with VLANs. A LAN can include a wide variety of network devices such as switches, firewalls, routers, load balancers, and sensors.
LANs can maintain connections with other LANs via leased lines, leased services, or the Internet using virtual private network technologies. Depending on how the connections are established and secured in a LAN, and the distance involved, a LAN may also be classified as a metropolitan area network (MAN) or a wide area network (WAN)."

"Microsoft SharePoint is a Web application platform developed by Microsoft. First launched in 2001, SharePoint has historically been associated with intranet, content management and document management, but recent versions have significantly broader capabilities.
SharePoint comprises a multipurpose set of Web technologies backed by a common technical infrastructure. By default, SharePoint has a Microsoft Office-like interface, and it is closely integrated with the Office suite. The web tools are designed to be usable by non-technical users. SharePoint can be used to provide intranet portals, document & file management, collaboration, social networks, extranets, websites, enterprise search, and business intelligence. It also has system integration, process integration, and workflow automation capabilities.
Enterprise application software (e.g. ERP or CRM packages) often provide some SharePoint integration capability, and SharePoint also incorporates a complete development stack based on web technologies and standards-based APIs. As an application platform, SharePoint provides central management, governance, and security controls for implementation of these requirements. The SharePoint platform integrates directly into IIS - enabling bulk management, scaling, and provisioning of servers, as is often required by large organizations or cloud hosting providers."

"In computer networking, cloud computing is computing that involves a large number of computers connected through a communication network such as the Internet, similar to utility computing. ...
Network-based services, which appear to be provided by real server hardware, and are in fact served up by virtual hardware, simulated by software running on one or more real machines are often called cloud computing. Such virtual servers do not physically exist and can therefore be moved around and scaled up or down on the fly without affecting the end user, somewhat like a cloud becoming larger or smaller without being a physical object. ...
Typically, the seller has actual energy-consuming servers which host products and services from a remote location, so end-users don't have to; they can simply log on to the network without installing anything. The major models of cloud computing service are known as software as a service, platform as a service, and infrastructure as a service. These cloud services may be offered in a public, private or hybrid network. Google, Amazon,leadsquared.com, Oracle Cloud, Salesforce, Zoho, Access2MyPC, and Microsoft Azure are some well-known cloud vendors." [Cloud computing. Wikipedia]
