/seg'ment/ 1. A collection of pages in a memory management system.

2. A separately relocatable section of an executable program. unix executables have a text segment (executable machine instructions), a data segment (initialised data) and a bss segment (uninitialised data).

3. network segment.

4. To experience a segmentation fault. Confusingly, the stress is often put on the first syllable, like the noun "segment", rather than the second like mainstream verb "segment". This is because it is actually a noun shorthand that has been verbed.
