Key Difference between the Physical deal with and reasonable Address
Let us discuss some of the major crucial differences between Physical resolve vs reasonable Address:
A physical deal with is an attend to that shows the location of memory while a logical resolve shows the attend to of the CPU, i.e. The main processor unit generates the Address.One machine can have actually only one physics address. They space constant, so they cannot be changed. One device can have a range of reasonable addresses. Whereas reasonable addresses are dynamic, they can be changed.The memory management unit generates the physical address, while the CPU generates the logical address.The mapping of physical address to logical resolve is considered as a physical address. For programs, the CPU generates the collection of logical addresses recognized as a logical address space.A physical attend to cannot it is in accessed directly, while us can access logical addresses directly.Users cannot watch physical addresses if they can view logical addresses easily.Physical Addresses an are is a set of all Physical addresses created in a program. Also, reasonable Addresses space is a set of every Logical addresses created in a program.Physical addresses and Logical addresses need the same time because that compiling and load time addresses binding schemes. ~ above the various other hand, physical addresses and logical addresses take various times for execution.A physical address is provided to identify the place of the memory, while on the other hand, the logical attend to is supplied to access a physics address.You are watching: Name two differences between logical and physical addresses
Comparison Table
The table below summarizes the comparisons in between Physical resolve vs logical Address:
| Basics because that comparison | Physical Address | Logical Address |
| Definition | The physical attend to is a ar of memory/storage. | Logical addresses are generated by the CPU. |
| Generated By | The physical attend to is produced by MUM (Memory administration unit) | The logical deal with is created by the CPU (Central processor unit). |
| Accessed By | Users cannot access physical addresses directly. It supplies a logical attend to to access physical addresses. | Users can accessibility logical addresses directly. The is provided to accessibility physical addresses. |
| Space because that Address | A collection of the physical address is mapped into the logical deal with and is taken into consideration as a physical address. | CPU generates a set of the logical resolve corresponding to program are thought about as logical attend to space. |
| Visibility | It is no visible to the user. Users cannot watch the physical address. | It is clearly shows to the user. Users deserve to view logical addresses easily. |
| Variation | There is only one physical attend to for one device. Physical addresses room constant. | The reasonable addresses have the right to be varied. There are variations for the logical address. |
| Access come Change | A physical deal with cannot change. | The logical deal with can be change. |
| Uses | It is provided to uncover the physical location of the memory. | It is provided to view the physical address. |
| Time because that compilation and load time attend to binding schemes | Same as Logical addresses. See more: Power Of 10 To The Power Of 22 Table, Exponent Calculator | Same together Physical addresses. |
