Memory - Address Space

About

The range of memory that can be addressed is called an address space.

It is the total number of uniquely-addressable memory locations

Same as IO - Address Space in memory. ?

Hierarchy

Physical

Virtual

The two kind of physical memory addressing model may be paged creating a virtual memory address space.

When an application starts with an OS, creating a process, it gets its own chunk of virtual memory called the process address space.

Glossary

Physical

Memory - Physical Address Space (Physical Memory)

Virtual

Virtual Memory - Address Space

Linear

A linear address space is the linear address space of the processor

Segment

A segment address space is all the address that can be contained in a segment. It's called a logical address space

Logical

A logical address space is also known as a segment.

Property

Continuous

A continuous address space is an address space seen as one sequence of address.

A linear address space is one continuous address space example.
