What term describes a symbolic representation of a program or data in computing?

The correct term that describes a symbolic representation of a program or data in computing is "Code." In computing, code refers to the written instructions in a programming language that a computer can interpret and execute. It serves as a set of instructions that define how to perform specific tasks, manipulate data, or implement algorithms. Code can take various forms, from individual lines of programming to entire software applications, and it embodies the logic and functionality of programs.

The other options each represent different concepts in programming but do not fit the description provided in the question. A script typically refers to a file containing a sequence of instructions, often written in a scripting language, designed to be executed by an interpreter. An identifier is a name used to identify a variable, function, or other entities in code, but does not represent the program or data itself. A snippet refers to a small portion of code or a small segment of a program, which again doesn't encompass the broader meaning of a symbolic representation.
