COMPUTER SCIENCE 1.2.3 EXAM
1. Usability: The quality of how easy is it for a user to use an app without any
explanation outside of the app.
2. decompose: To break down a complex problem or system into smaller parts that
are more manageable and easier to understand
3. procedural abstraction: To break down a complex problem or system into small-
er parts that are more manageable and easier to understand
4. modulo: a mathematical operation that returns the remainder after integer divi-
sion.
5. Abstraction: hides details or removes duplication allowing the programmer to
focus on high-level considerations and functions rather than the rules of a program-
ming language
6. algorithm: a step-by-step procedure for solving a problem
7. Global Variable: A variable whose scope is "global" to the program, it can be used
and updated by any part of the code.
8. local variable: A variable with local scope is one that can only be seen, used and
updated by code within the same scope.
9. scope:
10. procedure: a sequence of actions or instructions to follow in solving a problem
or accomplishing a task
11. method: a function that is a member of a class
12. function: A block of organized and reusable code that performs a single action
13. result procedure: returns a calculation
14. do procedure: provides an answer to an output
1 m/
m1
