Three examples of language translators and four definitions are shown below. Draw lines to link each language translator to the correct one or more definitions. Definition Language translator The software reads the source code and reports all errors. The software produces an executable file. The software reads each statement and checks it before running it. The software halts when it encounters a syntax error. The software translates a high-level language program into machine code for the processor to execute. The software translates low-level statements into machine code for the processor to execute. Compiler Assembler Interpreter

Jay is developing a computer game that allows users to create stories. Jay uses a language translator to develop the computer game. Tick (3) one or more boxes in each row to identify the language translatoreach statement describes. Statement Assembler Interpreter Compiler Translates and executes each line of source code one line at a time Translates low-level source code into machine code Must be present in memory to execute the code Translates high-level source code into low-level code Jay decides to use a compiler to develop the game. Identify two benefits of using a compiler. Benefit 1 Benefit 2 The game generates a story which is stored as a text file. Jay compresses the text file using lossless compression before sending it by email to his friend. Identify two reasons for compressing the text file. Explain the reasons why Jay compresses the text file with lossless compression instead of lossy compression.

A game program is written which can be either interpreted or compiled. The table below shows five statements about the use of interpreters and compilers. Tick (✓) to show whether the statement refers to an interpreter or to a compiler. Statement Interpreter Compiler This translator creates an executable file When this translator encounters a syntax error, game execution halts The translator analyses and checks each line just before executing it This translator will produce faster execution of the game program Use of this translator makes it more difficult for the user to modify the code of the game

The diagram shows three items of software that translate program code. Draw one line from each context to the correct item of translation software. Assembler Interpreter Compiler Context Item of translation software A web page contains a client-side script. Each instruction in the source code consists of an op code and an operand. The source code is required at run-time. When the source code is translated, copies of the executable program can be distributed without the need for the source code. The Java programming language is said to be machine or platform independent. Describe what is meant by machine independent. Describe how a Java source code program is translated.

The diagram shows three items of software that translate program code. Draw one line from each context to the correct item of translation software. Assembler Interpreter Compiler Context Item of translation software The source code is written in a high-level language. An executable file is produced. The source code uses instructions from the processor’s instruction set. The source code and translation software must both be in main memory at execution time. A web page contains some JavaScript code. A programmer is developing software and has both a compiler and interpreter for the high-level language used. Describe two benefits of using each form of translation software. Benefits of a compiler Benefits of an interpreter

Draw one or more lines to link each language translator to the most appropriate statement. Language translator Statements Compiler Interpreter Converts a low-level language instruction into binary Stops as soon as it finds a syntax error Needs the source code to be present when the user’s program is run Reports all errors found at the end of the process Corrects syntax errors as they are detected Converts a high-level language into a different form Creates an executable file
