How logical address is different from physical address?
The basic difference between Logical and physical address is that Logical address is generated by CPU in perspective of a program whereas the physical address is a location that exists in the memory unit.
What is the difference between a logical or virtual memory address and a physical memory address?
Physical Address: The address of where something is physically located in the RAM chip. Logical/Virtual Address: The address that your program uses to reach its things. It’s typically converted to a physical address later by a hardware chip (mostly, not even the CPU is aware really of this conversion).
What is physical memory 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 the difference between physical memory and virtual memory?
Physical and virtual memory are forms of memory (internal storage of data). Physical memory exists on chips (RAM memory) and on storage devices such as hard disks. Virtual memory is a process whereby data (e.g., programming code,) can be rapidly exchanged between physical memory storage locations and RAM memory.
What is physical address and logical 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 paging explain how logical address is mapped to physical address?
The mapping from virtual to physical address is done by the memory management unit (MMU) which is a hardware device and this mapping is known as paging technique. The Physical Address Space is conceptually divided into a number of fixed-size blocks, called frames.
What is logical address in microprocessor?
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 the difference between a virtual memory address & A physical memory address which is larger & Why?
The main difference between physical and virtual memory is that the physical memory refers to the actual RAM of the system attached to the motherboard, but the virtual memory is a memory management technique that allows the users to execute programs larger than the actual physical memory.
What are the differences between physical and logical computer security?
Physical security keeps them safe by allowing only authorized individuals into the building. Logical security protects their computers and data from unauthorized access.
What is the physical address associated with the logical address?
Logical address is an address generated by the CPU during execution, whereas Physical Address refers to the location in the memory unit(the one that is loaded into memory). The logical address undergoes translation by the MMU or address translation unit in particular.
