What does internals mean?
Internals means the parts or workings found inside a machine, structure, body, or other object. The word is especially useful when describing the concealed components of a device or the internal organization of something complex: one might examine the internals of an engine, a building, or a computer system. It also has a figurative use for the private affairs or decision-making processes of a group. In this sense, the expression can suggest that the speaker is revealing details that are normally hidden, confidential, or difficult to understand. “The internals of the government” sounds more neutral than “the political internals of the company,” which may imply criticism or gossip. Although the literal sense is concrete and technical, the figurative sense is broad and often somewhat informal.

Where does internals come from?
The word is the plural of “internal,” an adjective borrowed from Latin internus, meaning “inner” or “inward.” “Internals” originally referred to inner parts and later came to denote internal affairs or workings. The same Latin root underlies related English words such as “internal,” “intern,” and “internality,” as well as the broader sense of “internal” as “within” or “inward.”
How internals is actually used
Usually used in the plural. The organizational sense can be informal or mildly critical, especially in expressions such as “the political internals” or “the internals of a dispute.”
