Where is logical address space stored?
The logical address does not exist physically in the memory whereas physical address is a location in the memory that can be accessed physically. Identical logical addresses are generated by Compile-time and Load time address binding methods whereas they differs from each other in run-time address binding method.
Where the operating system is stored?
hard disk
The hard drive (sometimes called the hard disk) is the main storage device in your computer. Like RAM, it can be added to and changed, and like ROM it is non-volatile, but it is slow. If you have files and folders on your computer, are stored on the hard drive. The operating system is also stored on the hard drive.
Why logical address is used in a computer system?
Logical address is used to reference to access the physical memory location. A logical address is generated so that a user program never directly access the physical memory and the process donot occupies memory which is acquired by another process thus corrupting that process.
What is logical memory in OS?
Logical memory is the address space, assigned to a logical partition, that the operating system perceives as its main storage. You can dynamically add logical memory to the shared memory partition up to this value. Desired. The amount of logical memory with which you want the shared memory partition to activate.

Which device uses logical addressing system?
Ques-2: Which device uses logical addressing system? Explanation: Since, Router can use logical as well as physical addressing system.
How is logical address converted to physical address?
The logical address undergoes translation by the MMU or address translation unit in particular. The output of this process is the appropriate physical address or the location of code/data in RAM. If you know that during compile time, where process will reside in memory, then an absolute address is generated.

What is physical address space in operating system?

What is logical address space?
The logical address is virtual address as it does not exist physically, therefore, it is also known as Virtual Address. This address is used as a reference to access the physical memory location by CPU. The term Logical Address Space is used for the set of all logical addresses generated by a program’s perspective.
Which hardware device is used for mapping logical address to physical address?
The hardware device called Memory-Management Unit is used for mapping logical address to its corresponding physical address. Physical Address identifies a physical location of required data in a memory. The user never directly deals with the physical address but can access by its corresponding logical address.
What is a logical address in Linux?
Logical Address 1 This address is generated by CPU. 2 The address space consists of the set of all logical addresses. 3 These addresses are generated by CPU with reference to a specific program. 4 The user has the ability to view the logical address of a program. 5 The user can use the logical address in order to access the physical address.
