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
Logical Channel Physical channel Similar to computers, we need a set of The physical layer specifies how the information instructions and ports to instruct different from different voice and data services are formatted elements of the network to perform specific into packets and sent through the radio channel. duties. In telecommunications, these ports are called as logical channels.
One difference is that inductive effects are based on the electronegativity of an atom and occur through the sigma bond network. The resonance effect donates electrons to the benzene ring and occurs through the pi bond network.
It means how the items (for instance, devices in a network) are actually connected.
End-to-end delay is the time it takes a packet to travel across the network from source to destination.Delay jitter is the fluctuation of end-to-end delay from packet to the next packet.
The interface between the network terminal (NT) on the user's premise and the terminal equipment (TE1) and (TE2)
The difference between architecture and topology is logical vs physical. Architecture is about the logical design of something. Topology is about the physical elements required to enable the architectural design. The difference between architecture and topology is logical vs physical. Architecture is about the logical design of something. Topology is about the physical elements required to enable the architectural design.

Physical topology are says how the wire are interconnected, while Logical topology is how the network behaves and interoperates.Sk wasim ul HaqueKharagpur, Madpur
Network topologies is the means in which a network is structured. There are two types being physical and logical. Logical topology shows how data is delivered between a network.

Layer 3 network addresses are logical addresses and can be easily changed by software.
The physical connection is layer 1 of the OSI model, and is the medium through which the data is transfered. i.e., cables The logical connection is layer 3 of the OSI model, and is the network portion. Using the Internetwork Protocol (IP), each host is assigned a 32 bit IP address. e.g. 192.168.1.1
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.

Network topology is the manner in which the physical components of a LAN are connected together. Network topology can be either physical or logical.
Physical data structure: This is the physical equipment involved in the network eg router, cabling etc). Logical data structure: This is how the information flows internally and externally (the transfer of information from one node to another on the network).
Network topology is the arrangement of the various components that make up the structure of a computer network. Network topology may be depicted in a physical or logical manner.
LUN = Logical Unit NumberVolume = a physical diskDepending on how the storage is configured a LUN may correspond to: a single physical volume as a single logical unitseveral physical volumes being treated as a single logical unitone partition within a physical volume formatted as several partitions (with each partition as a single logical unit)The concept of a LUN makes it easy for programs to access the disks and makes it easy to perform maintenance on the disks by shuffling the LUNs between physical disks as needed. The programs do not need to be changed or reconfigured when a physical drive is removed, replaced, or upgraded to one of greater capacity (or converted to RAID storage).
