What is Ctrl + C?
rm -r
What is recursive delete?
Languages like Java, Python, and Go run this automatic memory-management process, which reclaims heap space from objects no longer reachable by the program — so you never have to call free() yourself.
What is garbage collection?
Expressed in Big-O notation, this is the worst-case time complexity of accessing an arbitrary element by its index in a standard contiguous array.
What is O(1) (or constant time)?
This phrase stands for NDS and references an individual’s computer at the firm.
What is Network Desktop Solution?
When working in a browser or an electron app, pressing this key by itself will immediately open the Developer Tools.
What is F12?
mkdir -p </this/is/a/path>
What is parent directory create?
This attack slips malicious input like ' OR 1=1' into an unsanitized query string; parameterized statements and prepared queries are the standard defense.
What is SQL injection?
Along with the NOR gate, this inverted-conjunction gate is designated as a "universal gate" because any boolean logic function can be synthesized entirely from it
