What are address space?

By Dinesh Thakur

1.Most generally, the range of values within which an ADDRESS has meaning and can be guaranteed to be unique. In everyday life, for example, each street constitutes a separate address space so that the same number, 12, might be used to describe different houses in Acacia Avenue and Laburnum Grove.

2 The range of contiguous memory addresses allocated to a single TASK or PROCESS.

3 The full range of PHYSICAL addresses that a computer’s processor can access, which is determined directly by the width of the processor’s ADDRESS BUS: a 16-bit bus can address 65,536 words (216) while a 32-bit bus can address 4,294,967,296 words (232), which would correspond to 4 gigabytes if the machine uses BYTE-ADDRESSING.
