Jul 10, 2013 · The physical address space could have a different size.

This address is generated by the CPU. .

.

So a 32-bit process is necessarily limited to an address space of 4GB, because it uses 32-bit pointers, regardless of OS.

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 main aim of memory management is to achieve efficient utilization of memory. The memory can be either physical or virtual and is used for executing instructions and storing data.

Address Space: Logical Address Space is set of all logical addresses generated by CPU in reference to a program.

In a 32-bit system with memory page size of 4KB (2^2 * 2^10 B), the maximum. Address Space can be of two types. That is, it is the memory that a program or process can access.

A computer's address space is the total amount of memory that can be addressed by the computer. Address Space can be of two types.

The number of address spaces available.

Some operating systems support only static linking, in which system language libraries are treated like any other object module.

It is computed by the Memory Management Unit (MMU).

The set of all physical addresses corresponding to the Logical addresses is commonly known as Physical Address Space. . Memory management is a method in the operating system to manage operations between main memory and disk during process execution.

. . The role of the kernel is to manage applications running in this space from messing with each other, and the machine. g. . From a software point of view, we (generally) don't care where they data is stored.

Then Dave illustrates the stack within a process address space (the addresses managed by a process): the heap is at the bottom of memory, just above the program (text) and grows upwards.

. In it mapping from the virtual address space to the physical address space is performed at run-time.
