A logical (or virtual) address is a reference to a memory location independent of the
current assignment of data to memory; a translation must be made to a physical
address before the memory access can be achieved.
A relative address is the address expressed as a location relative to some known
point, usually the beginning of the program.
A physical address, or absolute address, is an actual location in main memory.

∙ 11y agoLogical address - generated by the CPU; also referred to as virtual address.
Physical address - address seen by the memory unit (loaded into memory-address register).
Logical and physical addresses are the same in compile-time and load-time address-binding schemes; logical (virtual) and physical addresses differ in execution-time address-binding scheme.
Logical address space: the set of all logical addresses generated by a program.
physical address space: the set of all physical addresses corresponding to these logical addresses
The user program deals with logical addresses; it never sees the real physical addresses.

A relative address is a particular example of logical address, in which the address is expressed as a location relative to some known point, usually a value in a processor register.
A physical address, or absolute address, is an actual location in main memory.

What is logical address in computer networks?
logical address is called as global address and physical address is called as local address .the ip address,which is used by the user in the network is found to be global for use and it is easily identified in any network .physical address is mac address ,which is stored in the nic card,which is mainly used ,when the system is connected in the network using switch
What is LDA in subject of computer system architecture?
LDA in terms of computer system architecture stands for Logical Device Address. A LDA is a one byte address (i.e an upper MAC address) and there is no physical address (i.e lower MAC address) specified.

What Logical record and physical record?
In record design we distinguish between logical and physical records. LOGICAL RECORDS: A logical record maintains a logical relationship among all the data items in the records.It is the way the programmer or user sees the data.IN CONTRAST, A PHYSICAL RECORD is the way data are recorded on a storage medium.The programmer doesnt know about the physical map on the disk.The software presents the logical record in the required sequence.The capability is unique to the data base design. This question is answered by Silpa Sonali Sahoo.I request all the User if you can give some extra knoweldge/idea based on the discussed topic then you are most welcome.
What is a physical port?
A physical port, as opposed to a virtual or logical port is an interface on a computer into which you can insert a connector for a device.
Which address is more important the physical address or the logical address?
In the 8086/8088 the physical address and logical address have the same importance, because they both relate to the address of the operand. It is true that the offset (logical) address is added to the segment address to determine the physical address, but the limitations of the architecture of the processor forces programmers to consider both.If you are talking about a virtual environment, however, such as in the 80286 or higher, then the logical address is more important than the physical address, because the logical address is the address of the operand, while the physical address is (somewhat) arbitrarily assigned by the operating system.
Each Logical Address is dependent of what?
A Physical Address...
Can physical address and virtual address be same?
your question is wrong. it should be "can physical address and logical address be same" answer is no because logical address is the combination of page number and offset whereas physical address is the combination of physical page[frame] and offset
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.
Why you need memory physical address and memory logical address?
Physical Address refers to Storage location on Physical Memory wheres Logical Addressing is used by Memory Managing Programs to refers addresses from Physical Memory and Virtual Memory.
What is logical address space and physical address space?
Logical address is the address generated by the CPU (from the perspective of a program that is running) whereas physical address (or the real address) is the address seen by the memory unit and it allows the data bus to access a particular memory cell in the main memory. All the logical addresses need to be mapped in to physical addresses before they can be used by the MMU. Physical and logical addresses are same when using compile time and load time address binding but they differ when using execution time address binding.
What kind of memory address does a CPU generate?
- An MMU (memory management unit) generates physical address. - A CPU (central processing unit) generates a logical address.
Which data structure convert logical to physical address?
Linear data structure is used to convert the logical address to physical address .Stack is used in this and the various conversion such as postfix,prefix and infix notation are come in this
Formula to get logical to physical address in paging?
(frame no * page size) + offset value = physical add where frame value is the value present in the corresponding page number offset value is the last n bits of the logical address page no is the first m-n bits of logical address 2^m is the logical address 2^n is the page size
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.
In paged system Can the logical address space b larger than physical address space?
Yes. This is the fundamental premise of paged or virtual memory - that you can have more logical memory than physical memory.
Are network layer address physical or logical?
Layer 3 network addresses are logical addresses and can be easily changed by software.
