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

Answer 1

ll for starters a physical network design well, as the name implies, involves the physical connectivity of each of your hosts on the network. this speaks of the actual physical layout of your network which includes the actual nodes, segments and hosts that appear on the actual layout. on the other hand, a logical network speaks more of data flow in your network. this may be of the different forms of network topology (e.g bus, ring, etc).

the difference of the two lies in the way they are presented. one being the real connection layout (physical) while the other is of how data flows within the network (logical).

think of it as like cars and roads. the roads represent the physical network wherein each road are interconnected and ends with a destination while the cars represent the logical part of the network wherein they move towards a certain destination within the network. although physical and logical networks vary in meaning still they work hand in hand to better define the same single and structured network.
A physical network is different from a logical network. Logical networks are defined at the Network layer by the arrangement of the hierarchical addressing scheme. Physical networks represent the interconnection of devices on a common media. Sometimes, a physical network is also referred to as a network segment

Answer 2

Memory in each logical partition operates within its assigned minimum and maximum values.

Physical memory is a term used to describe the total amount of memory installed in the computer. For example, if the computer has two 64MB memory modules installed, it has a total of 128MB of physical memory. Answered by: QWERTY

Answer 3

The term Logical Security is colloquially used to refer to electronic measures such as permissions within the operating system or access rules at the network layers such as the firewall, routers and switches.

Physical security is traditionally used to describe controlled entry doors, video surveillance and other metaphysical measures.

The overlap between the two is ever increasing since systems which provide logical security have some physical security measures such as key lock panels on server face plates and when physical systems such as the HiD card reader for the door entry systems use a server to maintain user and card records and the ever increasing number of PC based DVR's for video surveillance cameras.

Answer 4

physical storage involves how data is written and organized on storage media; logical storage involves how OS and BIOS organize and view stored data.
