Code space

In computer programming, code space is the memory segment in the main memory allocated to a process to store the code in execution.

In multi-threading environment, threads share code space along with data space, which reduces the overhead of context switching considerably as compared to process switching.

For a character encoding the code space (or codespace) is the range of numerical values available for encoding characters. For example, Unicode has a code space comprising a range of integers from 0_hex to 10FFFF_hex. Each value in the code space is known as a code point.
