An address space is a range of logical space on any part of a computer or a peripheral device where data can be stored. For instance, on a memory chip, each byte of data has its own address where it can be stored and then located at a later time. There are limits to what the address can be, based upon the physical limitations of the device, as well as arbitrary limits that are used to separate certain types of data from one another.
Examples of address spaces
- Memory addresses in a computer's RAM or virtual memory.
- Addresses on a network, such as IP addresses.
- Sector addresses on disk drives.
- File names in a file system volume.
