Adeel has used a high-level language to program a mobile application. Describe what is meant by a high-level language. Adeel uses an interpreter while developing and testing the application. Adeel uses a compiler when the application is ready to be shared with others. Compare the features of interpreters and compilers. Adeel is considering distributing his application as free software or shareware. Explain the difference between free software and shareware. Adeel is concerned about his application being plagiarised. Define the term plagiarism. Adeel copyrights his application. State why Adeel copyrights his application.

A programmer has designed a three‑dimensional (3D) interactive computer game. They are going to develop a program for the game. The program needs to run efficiently, but it must also be developed as soon as possible. Tick (✓) one box to identify whether the programmer should use a high‑level language or a low‑level language to develop the program. Explain the reasons for your choice. High‑level language Low‑level language Reasons for your choice If the programmer chooses a high‑level language, they can use a compiler or an interpreter to translate the high‑level language into a low‑level language. Describe the operation of a compiler and of an interpreter. Compiler Interpreter

Five statements about interpreters and compilers are shown in the table below. Study each statement. Tick (✓) to show whether the statement refers to an interpreter or to a compiler. Statement Interpreter Compiler creates an executable file that runs directly on the computer more likely to crash the computer since the machine code produced runs directly on the processor easier to debug since each line of code is analysed and checked before being executed slow speed of execution of program loops it is more difficult to modify the executable code, since it is in machine code format State why a compiler or an interpreter is needed when running a high-level program on a computer. Give one benefit of writing a program in a high-level language. Give one benefit of writing a program in a low-level language. Study the following three sections of code. A: 1 0 1 0 1 1 0 1 1 1 0 0 1 1 1 0 1 0 1 1 0 1 1 1 B: LDA X INC X STA Y C: FOR x ← 1 TO 10 READ n ENDFOR Identify, using the letters A, B or C, which of the above codes is an example of assembly code, high-level language code or machine code: Assembly code High-level language code Machine code
