In computer architectures, a logical address is the address at which a memory location appears to reside from the perspective of an executing application program. This may be different from the physical address due to the operation of a memory management unit (MMU) between the CPU and the memory bus. Physical memory may be mapped to different logical addresses for various purposes. For example, the same physical memory may appear at two logical addresses and if accessed by the program at one address, data will pass through the processor cache whereas if it is accessed at the other address, it will bypass the cache.

Brief in What is the Difference between physical DFD and logical DFD?
A logical DFD makes it easier to communicate for the employees of an organization, leads to more stable systems, allows for better understanding of the system by analysts, is flexible and easy to maintain, and allows the user to remove redundancies easily. On the other hand, a physical DFD is clear on division between manual and automated processes, gives detailed description of processes, identifies temporary data stores, and adds more controls to make the system more efficient and simple. simply put… 1. Logical DFDs are not concerned about how the system is or will be constructed while Physical DFDs show how the system is or will be constructed. 2. Physical DFDs are more realistic and complex while Logical DFDs are simpler but provide an easier understanding view

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

Is ARP the core protocol responsible for logical addressing?
The structure of the question is meant to trick you because 'logical addressing' is being used loosely. Technically, IP is the CORE protocol responsible for logical addressing. ARP is the network layer protocol that is used to discover the identity(physical address) of a machine whose IP address you know. Very briefly, it does this by creating a database that maps the MAC address to the (hosts') logical address provided.
What is true concerning physical and logical topologies?
Logical topologies consist of virtual connections between nodes.
Which one between logical and physical data independent is harder to achieve and why?
the logical data independence is hard to achieve because all the manipulation is belonging in logical data independence but in physical data independence only show the physical view .
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 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 similarities between logical file and physical file?
three similarities is that physical file deals with does file that a
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.
