What is network explain with diagram?

A network diagram is a visual representation of a computer or telecommunications network. It shows the components that make up a network and how they interact, including routers, devices, hubs, firewalls, etc. A network diagram can be either physical or logical.

What should a network diagram include?

A logical network diagram illustrates the flow of information through a network and shows how devices communicate with each other. It typically includes elements like subnets, network objects and devices, routing protocols and domains, voice gateways, traffic flow and network segments.

What is network diagram in project?

A Network Diagram is a graphical way to view tasks, dependencies, and the critical path of your project. Boxes (or nodes) represent tasks, and dependencies show up as lines that connect those boxes. After you’ve switched views, you can add a legend, customize how your boxes appear, and print your Network Diagram.

What are the different types of network diagram?

There are two main types of network diagrams in project management: the arrow diagramming method (ADM), also known as “activity network diagram” or “activity on arrow”; and the precedence diagramming method (PDM), also known as “node network” or “activity on node.”

What are the 4 types of networks?

A computer network is mainly of four types:

• LAN(Local Area Network)
• PAN(Personal Area Network)
• MAN(Metropolitan Area Network)
• WAN(Wide Area Network)

What is the difference between a physical and logical network diagram?

A logical network diagram usually shows network devices like routers, firewalls, and voice gateways. A physical network diagram shows how the network devices are physically connected together, and therefor all ports on all devices on the network are represented here. This will include cables.

What is logical flow diagram?

Logical data flow diagram mainly focuses on the system process. It illustrates how data flows in the system. Logical DFD is used in various organizations for the smooth running of system. Like in a Banking software system, it is used to describe how data is moved from one entity to another.

What is the physical or logical arrangement of a network?

Explanation: The logical arrangement of the nodes of different networks to communicate is called as topology.

What is the physical configuration of a network called?

Different types of network configuration in computer networks are commonly referred to as network topologies. A network topology describes how the nodes or devices (physical or virtual) in a network are arranged and how they communicate with each other.

What are the two types of network configuration?

Networks are divided into two types, a LAN (Local Area Network) or a WAN (Wide Area Network), which are generic terms referring to two important basic types of networks.

What are the types of network configuration?

• Personal Area Network (PAN)
• Local Area Network (LAN)
• Wireless Local Area Network (WLAN)
• Campus Area Network (CAN)
• Metropolitan Area Network (MAN)
• Wide Area Network (WAN)
• Storage-Area Network (SAN)
• System-Area Network (also known as SAN)

Which topology is best?

A Star Network Topology is best suited for smaller networks and works efficiently when there is limited number of nodes. One has to ensure that the hub or the central node is always working and extra security features should be added to the hub because it s the heart of the network.

Which topology is fastest?

Theoretically the fastest topology should be mesh topology. But the best topology is star topology.

Which topology is used in schools?

Ring Network Topology Ring network topologies are most often found on school campuses, though some commercial organizations also use them. FDDI, SONET, or Token Ring technology are typically used.

Which topology is the most expensive?

Star topology is the most popular way to connect a computer in a workgroup. It is expensive due to the cost of the hub. Star topology uses a lot of cables, which makes it the most costly network to set up as you also have to trunk to keep the cables out of harm.

What is the cheapest topology?

Star and Extended Star Topologies This type network is easy to setup, relatively inexpensive, and provides more redundancy than other topologies, i.e. bus topology. The star topology is configured by connecting all of the nodes on the network to central device.

What is a full mesh topology?

With a full mesh network topology, each node is directly connected to every other node. This enables a message to be sent along many individual routes. With a partial mesh network topology, not all nodes are connected directly to each other.

Which of the following is the most expensive computer?

1. Supercomputer – The fastest, largest, most powerful and most expensive computer.

What are the 5 classification of computer?

Classes by purpose

• Microcomputers (personal computers)
• Minicomputers (mid-range computers)
• Mainframe computers.
• Supercomputers.
• Servers.
• Workstations.
• Information appliances.
• Embedded computers.

What do you think is the most powerful type of computer Why?

The most powerful computers are supercomputers.
