Word scramble
Unscramble the letters and write each key term on the line.
1
LIAYSNAS
The first stage of the PDLC: work out exactly what problem must be solved and what the program must do, using abstraction and decomposition, before any design or code.
2
OBRELMP METEASTNT
A clear one or two sentence description of what needs to be solved and what the program must achieve, written so the user and the goal are obvious.
3
RNBITTCASOA
Keeping only the details needed to solve a problem and leaving out the details that do not matter, e.g. a map shows roads but not every tree.
4
URMNQTERIEE
A statement of something the program must do or provide so that the problem is solved. It is specific, comes from the problem and the user, and is used later to test the program.
5
GIDNES ASTEG
The second PDLC stage: plan the solution in detail using decomposition, structure diagrams, flowcharts and pseudocode, before any program code is written.
6
OTFCHRLAW OLMSSBY
Six standard flowchart shapes: terminator (Start/Stop), process, input/output, decision (two exits), subroutine call, and flow lines with arrows showing direction.
7
NCGDIO EGTSA
The third PDLC stage, where the design (pseudocode or flowchart) is turned into program code in a programming language, written step by step and checked against the requirements.
8
VTAIETREI GTSNITE
Testing each small part of the code as it is written, fixing any errors, then retesting before moving on. This finds errors early and repeats until that part works.
