Internet Group Management Protocol (IGMP).
Computer and Network Examples
The Internet Group Management Protocol (IGMP) is a communication protocol of the multicast transfer data in the IP networks. IGMP is used by routers and IP hosts for organizing the network devices in groups.
IGMP is a part of IP multicast. IGMP is located at the network level. It is used only on IPv4 networks. IGMP can be used for one-to-many networking applications such as online streaming video and online gaming.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park. It shows the architecture of the network for delivering a multicast service using IGMP. IGMP is used by the client computer and the neighboring switches to connect a client and a local router that implements a multicast. Then between the local and remote routers is used the Protocol Independent Multicast (PIM). With its help the group traffic is routed from the video server to numerous clients of the group transfer.

When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology.
There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.

Local area network connects computers and other network appliances within an area, such as office building or a campus. It can be difficult to provide such network without a predesigned plan. For these purposes you can use network diagram software, which helps you to create LAN network diagrams and office network diagrams quickly and effortless. This will speed up your work and you can save the diagram for the future network improvements.
The following diagram illustrates a network topology of the small office. LAN configuration has a star topology. The local network joins 8 computers among which are several desktop PCs, laptop, two iMacs and iBook. The end-point devices are divided into three groups. Each group is connected to its hub. There is a network printer and a modem, which are interconnected with other devices through a network server. Each computer on the LAN can access the server through a corresponding hub.

The Cloud Computing Architecture is the structure of the system, which is based on the needs of end-user and includes the set of components and subcomponents required for cloud computing, among them cloud resources, services, middleware, software components, front-end platforms (cloud clients), cloud-based back end platforms (servers, storage), and a network (Internet, Intranet, Intercloud). When designing the Cloud Computing Architecture diagrams, the ConceptDraw DIAGRAM diagramming and vector drawing software advises to turn attention for the powerful Cloud Computing Diagrams solution from the extensive Computers and Network area of ConceptDraw Solution Park.

It's no secret that there is a list of skills that every average system administrator should have. And it's important to be able to manage domains via active directory technologies. The best way to keep all the details in mind is to draw a diagram representing users, groups and domains.
This diagram represents an Active Directory Services (Active Directory Domain Services). It can be helpful for system and network administrators to organize a network physical and logical elements (domains, data bases, servers, network equipment, end-user computers etc.) into a secure and logical structure. The logical structure of Active Directory is a hierarchical organization of all network components. The data that is stored in Active Directory comes from some diverse sources. The Active Directory diagram created using ConceptDraw Active Directory Diagram solution. It shows allocating group policies and functions assigned to end users. It helps to plan, manage and maintain the certain user access scenario.

A well-organized mind map should contain multiple pages in which all servers are listed with a detailed configuration of each.
Computer networks nowadays are spread all across the world. The large number of parameters, such as geographic scale or communication protocols, can divide networks. One of the most common types of networks is called local area network (LAN). It convenient to represent network examples by means of diagrams.
This local area network (LAN) diagram provides an easy way to see the way the devices in a local network are interacted. The diagram uses a library containing specific symbols to represent network equipment , media and the end-user devices such as computers (PC, mac, laptop) , network printer, hubs, server and finally a modem. There are two types of network topologies: physical and logical. The current diagram represents precisely a physical type of LAN topology because it refers to the physical layout of a local network equipment.

A network diagram represents the set of computers and network devices and the connections among them. This scheme can be developed for any institution or establishment. To illustrate this concept let’s take for example, a hotel network topology diagram or a school network diagram. These diagrams depict access points, servers, workstations, firewalls and another equipment needed to provide a network.
On this masterpiece drawing one will see a simple scheme a of connecting computers together. Such form of connecting can be applied for a hotel, guest house, bungalow, hut or something else. This diagram shows the images of the real LAN components. So, it represents a physical category of a network construction. It looks similar to a star - so this network configuration is named a star topology. The typical feature of this construction is a center point - usually it is hub, or router. The rays of this star means network connections. Computers, peripherals and other network details are placed on the ends of the star rays.
