Word scramble
Unscramble the letters and write each key term on the line.
1
OCUERS ECOD
The instructions a programmer writes in a programming language. The CPU cannot run it until a translator turns it into machine code.
2
GHLH-LIVEE ANEGGUAL
A programming language using English-like words that is easy for people to read and write, such as Python or Java. One statement does many jobs, and it must be translated before the CPU can run it.
3
ELL-OEWLV GUAAEGNL
A programming language close to the CPU's instructions, such as machine code or assembly language. Each instruction is one simple CPU operation, so it is harder for people to read.
4
LLEH-VEHGI EDCO
Code that uses familiar words, so it is easier to read and write than low-level code, which needs many detailed instructions to do the same job.
5
IESRAE OT EBDGU
Debugging is finding and fixing errors. It is easier in short, readable high-level code than in long, hard-to-read low-level code, and translators give clearer error messages for it.
6
INECMHA ENPNDEITDEN
A language whose code can run on different types of computer. High-level languages are ______ (portable); low-level languages are machine dependent.
7
IHHV-EELGL SV OWV-EELLL
High-level is easy to read, debug and portable but gives less hardware control; low-level is hard to read and machine dependent but gives direct hardware control.
8
HSCOEO ANGUGALE VLLEE
Pick high-level for portable programs on many machines; pick low-level for direct hardware control, like drivers. Then justify the choice by linking it to the task's needs.
9
NMCMNIEO
A short, memorable code in assembly language, such as LDA, ADD or STO, that stands for one machine code instruction and is easier to remember than binary.

1OCUERS ECOD → source code — The instructions a programmer writes in a programming language. The CPU cannot run it until a translator turns it into machine code.
2GHLH-LIVEE ANEGGUAL → high-level language — A programming language using English-like words that is easy for people to read and write, such as Python or Java. One statement does many jobs, and it must be translated before the CPU can run it.

8HSCOEO ANGUGALE VLLEE → choose language level — Pick high-level for portable programs on many machines; pick low-level for direct hardware control, like drivers. Then justify the choice by linking it to the task's needs.
9NMCMNIEO → mnemonic — A short, memorable code in assembly language, such as LDA, ADD or STO, that stands for one machine code instruction and is easier to remember than binary.
