Slang Dictionary

code

n. The stuff that software writers write, either in source form or after translation by a compiler or assembler. Often used in opposition to "data", which is the stuff that code operates on. This is a mass noun, as in "How much code does it take to do a bubble sort?", or "The code is loaded at the high end of RAM." Anyone referring to software as "the software codes" is probably a newbie or a suit.

Computing Dictionary

code definition


1. Instructions for a computer in some programming language, often machine language (machine code).
The word "code" is often used to distinguish instructions from data (e.g. "The code is marked 'read-only'") whereas the word "software" is used in contrast with "hardware" and may consist of more than just code.
