Why are physical and logical topologies necessary?
When a problem arises, I.E.
a link is down, by simply looking at the physical layout, we are able to quickly identify where the problem is located, allowing us to quickly resolve it.
Having a visual view of a logical and physical network also helps identify possible security problems..
What is the difference between a physical network and a logical network?
Physical toplogy refers to the actual shape or layout of the wires in a network. The logical topology, on the other hand, refers more to how the data moves through the network. Another way of looking at this is we can say the logical topology refers to the pattern of the data flow in a network.
What is logical network diagram?
A logical network diagram describes the way information flows through a network. Therefore, logical network diagrams typically show subnets (including VLAN IDs, masks, and addresses), network devices like routers and firewalls, and routing protocols.
Which network is the smallest?
Personal Area NetworkPersonal Area Network (PAN) The smallest and most basic type of network, a PAN is made up of a wireless modem, a computer or two, phones, printers, tablets, etc., and revolves around one person in one building.
What is network size?
Network size is the number of nodes in a network.
What are physical and logical topologies?
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 are physical topologies?
The physical topology is the way you physically lay out the network, like a map, and the logical topology is the way the information flows on the network. Usually, the physical and logical topology is the same, but sometimes they can differ, such as in a physical star/logical ring topology.
What is logical in networking?
A logical network is a portion of a physical network that connects two or more logical network interfaces or devices. … A logical network interface or device is the software entity that is known by an operating system.
What is physical network?[′fiz·i·kəl¦net‚wərk] (computer science) A system of computers that communicate via cabling, modems, or other hardware, and may include more than one logical network or form part of a logical network.
What are the 4 types of networks?
Types of Computer NetworkLocal Area Network (LAN)Metropolitan Area Network (MAN)Wide area network (WAN)
How many types of logical topology are there?
two typesThere are majorly two types of logical topology which are bus topology and ring topology. The logical topology helps to identify the initial glitch in the network so that the network can be implemented without having any problems and data packets can be transmitted easily.
What are the 2 types of LAN networks?
