Difference Between Logical Address and Physical Address

The basic difference between Logical and physical address is that Logical address is generated by CPU in perspective of a program. On the other hand, the physical address is a location that exists in the memory unit. ... The set of all logical addresses generated by CPU for a program is called Logical Address Space.

What is logical and physical address in networking?

A physical address is an address that shows the location of memory while a logical address shows the address of the CPU, i.e. the central processor unit generates the Address. One device can have only one physical address. They are constant, so they cannot be changed. One device can have a variety of logical addresses.

What is the difference between logical and physical design?

The logical design is more conceptual and abstract than the physical design. In the logical design, you look at the logical relationships among the objects. In the physical design, you look at the most effective way of storing and retrieving the objects. Your design should be oriented toward the needs of the end users.

What are the physical address for the following logical addresses?

What are the physical addresses for the following logical addresses? Answer: 219+430 = 649. 2300 + 10 = 2310.

How is logical address converted to physical address?

Logical address is address generated by CPU during execution whereas Physical Address refers to location in memory unit(the one that is loaded into memory). Note that user deals with only logical address(Virtual address). The logical address undergoes translation by the MMU or address translation unit in particular.

Why do we need logical address?

The need of logical address is to securely manage our physical memory. ... The binding of instruction and data of a process to memory is done at compile time, load time or at execution time. Logical address comes into picture, only if the process moved during its execution time from one memory segment to another.

What is the purpose of physical address?

In computing, a physical address (also real address, or binary address), is a memory address that is represented in the form of a binary number on the address bus circuitry in order to enable the data bus to access a particular storage cell of main memory, or a register of memory mapped I/O device.

What is physical and logical database?

A logical database must be able to access and identify all files within the storage system to operate correctly, whereas a physical database manages a much smaller field of information. Sometimes, a physical database stores only a single file with one value or word in it.

What is logical structure of database?

Introduction to Logical Storage Structures. Oracle Database allocates logical space for all data in the database. The logical units of database space allocation are data blocks, extents, segments, and tablespaces. ... The data in the data files is stored in operating system blocks.

What are logical components?

Definition. A logical component is an administrative entity which assigns logical systems, in the entire system landscape and across projects, to the following: ... the system roles or phases in a project, e.g. the system role development system for the configuration.

Which address is a logical address?

In computing, a logical address is the address at which an item (memory cell, storage element, network host) appears to reside from the perspective of an executing application program. A logical address may be different from the physical address due to the operation of an address translator or mapping function.

What is your physical address?

A physical address, sometimes referred to as a street address, is used to describe where a place is geographically located. It often pertains to a geographic location under the jurisdiction of an administrative area or region that has some government function.

How physical address is calculated?

The address calculated when BP is taken as the offset gives the starting address of the stack. The address when SP is taken as the offset denotes the memory location where the top of the stack lies. Q3) The value of the DS register is 3032H. And the BX register contains a 16 bit value which is equal to 3032H.
