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.
A physical channel refers to the medium through which data is transmitted, such as a cable or wireless signal. A logical channel, on the other hand, represents a specific path or communication route within a network that allows data to be exchanged between devices. In simpler terms, a physical channel is the physical connection, while a logical channel is a virtual pathway for data flow.

What is difference between a logical network and physical?
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
What is the difference between physical structure and logical structure of a disk?
Physical structure refers to the actual layout of data on the disk, including sectors, tracks, and cylinders. Logical structure refers to how the operating system organizes and accesses data on the disk, such as partitions, file systems, and directories.
Difference between logical database and physical database?
A logical database refers to the conceptual schema or model of data relationships and structures, independent of how data is stored or accessed. On the other hand, a physical database involves the actual implementation of the database on a specific hardware system, detailing how data is stored and accessed. The logical database design focuses on the organization of data, while the physical database design focuses on optimizing performance and storage efficiency.
What is the difference between logical database and physical database?
A logical database refers to the way data is organized, modeled, and accessed by users, focusing on the structure and relationships of data. In contrast, a physical database relates to how data is actually stored on disks, including indexes, partitions, and access paths designed for efficient data retrieval and storage.
What is the difference between a thick and thin Logical Unit?
A thick Logical Unit refers to full physical storage capacity being allocated upfront, while a thin Logical Unit only allocates storage space as it is being used. This makes thin provisioning more efficient in terms of resource utilization and allows for better scalability as storage can be expanded dynamically.
Difference between physical and logical DFD?
difference between physical and logical data flow diagrams.
What are the difference between logical and physical tag?
While physical tags are also referred to as presentational mark-up, logical tags are useless for appearances. Physical tags are newer versions while logical tags are old and concentrate on content.
What is the difference between physical and logical topology?

What is the difference between network architecture and network topology?
Network architecture refers to the design and structure of a network, including components, protocols, and technologies used for communication. Network topology, on the other hand, refers to the physical or logical layout of devices and how they are connected in a network, such as bus, star, ring, or mesh. In essence, network architecture defines how components work together, while network topology defines how components are arranged.
What is the difference between virtual logical and physical address spaces?
The concept of a logical address space is simply involved the process of mapping the Logical addresses to their Physical Addresses . Logical addresses are generated by the CPU; also referred to as virtual addresses.while Physical Address is the actual address of the data stored on the physical device and mapped by MMU.
What is the difference between a logical view and a physical view of data?
The logical view presents data as they would be perceived by end users or business specialists, whereas the physical view shows how data are actually organized and structured on physical storage media.
What is difference between logical file and physical file?
* Physical file (PF) contains the data and have only one record format. Logical file (LF) is a view of the physical file which does not contain any data may be based on one physical file or more then one physical file. Logical file can have more then one record format. Logical can be non join or join logical file. Performance becomes better if you use the logical file in the program.
What Difference between logical versus physical address storage?
A physical address is concrete and never changes. It is set in memory. A logical address is made up of a base pointer and an offset.It keeps programs running parallel and not intertwining.
