Code segment

In computing, a code segment, also known as a text segment or simply as text, is a phrase used to refer to a portion of memory or of an object file that contains executable computer instructions. It has a fixed size and is usually read-only. If the text section is not read-only, then the particular architecture allows self-modifying code. Read-only code is reentrant if it can be executed by more than one process at the same time.

<memory> (Intel 8086 CS) The area of memory containing the machine code instructions of a program. The code segment of a program may be shared between multiple processes running that code so long as none of them tries to modify it.
Unix, confusingly, calls this the "text segment" and the area for uninitialied data, the bss segment.
Initialised data is located in the data segment
