What is physical connection in networking?

What is physical connection in networking?

The physical network consists of the cables (coaxial cable, twisted pair, fiber optic, and telephone lines) that connect the different hardware residing on the network, the adapter used on computers connected to the network (hosts), and any concentrators, repeaters, routers, or bridges used in the network.

What is logical and physical connections explain with example?

For example, in a shared Ethernet network that uses hubs rather than switches, the logical topology appears as if every node is connected to a common bus that runs from node to node. However, its physical topology is a star, in which every node on the network connects to a central hub.

What’s a logical connection?

A logical network is a virtual representation of a network that appears to the user as an entirely separate and self-contained network even though it might physically be only a portion of a larger network or a local area network.

What is the difference between logical and physical network design?

Logical design of a network consists of virtual design while the physical design of a network describes the hardware functions of the network. Logical designs determine the flow of data or communication between two networks while physical design is a communication between two computers connected with cables.

What is logical communication in networking?

By “logical” communication, we mean that although the communicating application processes are not physically connected to each other (indeed, they may be on different sides of the planet, connected via numerous routers and a wide range of link types), from the applications’ viewpoint, it is as if they were physically …

What do you mean by logical connection and application?

Logical connectors are used to join or connect two ideas that have a particular relationship. These relationships can be: sequential (time), reason and purpose, adversative (opposition and/or unexpected result), condition.

What is the meaning of physical logical?

Logical implies a higher view than the physical. Users relate to data logically by data element name; however, the actual fields of data are physically located in sectors on a disk. For example, to find out which customers ordered how many of a particular product, the logical view is customer name and quantity.

What is the use of physical and logical topology?

A physical topology describes how network devices are physically connected – in other words, how devices are actually plugged into each other. We’re talking about cables, wireless connectivity, and more. A logical topology describes how network devices appear to be connected to each other.

What is physical and logical network diagram?

Logical network diagrams focus in on how traffic flows across the network, IP addresses, admin domains, how domains are routed, control points, and so on. A physical network diagram will, ideally, show the network topology exactly as it is: with all of the devices and the connections between them.

Which is the physical network of computers all over the world?

The Internet
The Internet is the world’s largest computer network.

What is physical and logical address in networking?

A physical address is an address that shows the location of memory while a logical address shows the address of the CPU, i.e. the central processor unit generates the Address. One device can have only one physical address. They are constant, so they cannot be changed. One device can have a variety of logical addresses.

What describes the logical topology of a computer networks?

A logical topology is a concept in networking that defines the architecture of the communication mechanism for all nodes in a network. Using network equipment such as routers and switches, the logical topology of a network can be dynamically maintained and reconfigured.
