Translators

Question 1

Advantages of High level
language

Answer 1

• Easier for programmers to read, write and understand programs
• Less likely to make mistakes
• Easier to debug
• Machine independent, the code is portable

Question 2

Disadvantages of high level language

Answer 2

• The program may be less memory effecient
• Needs to be translated to machine code before running
• The user is not able to directly manipulate the hardware
• May not be able to make use of special hardware

Question 3

Whats a low-level language

Answer 3

programming languages that are similiar to a computer’s instruction set. These are basic instructions that the CPU will understand

Question 4

A list of machine code commands that a CPU can process:

Answer 4

Instruction Set

Question 5

Low-level language examples and what they’re written in.

Answer 5

1. Assembly language, written in mnemonics
2. Machine code, written in binary

Question 6

Disadvantages of low-level language

Answer 6

• Take a longer time to write and debug programs
• Programs are more difficult to understand/read/learn
• Programs are not portable (machine dependent)
• More prone to errors

Question 7

What translates assembly language into machine code

Answer 7

Assembler

Question 8

How compiler translates a program

Answer 8

• It translates high level language to machine code.
• It translates ALL the code BEFORE it is executed
• Creates an executable file.
• Compiled programs are run without the compiler.
• Provides error report for whole code if error is detected

Question 9

How interpreter translates a program

Answer 9

• It translates high level language to machine code.
• translates one line of code and then executes it before moving on to the next line.
• Stops execution of program when an error is found
• Allows error correction in real time.
• No executable file is produced.
• Interpreted programs cannot be run without the interpreter.

Question 10

When to use compiler, interpreter, and assembly language.

Answer 10

• Compiler: compiled program usually distributed for general use.
• Interpreter: when a program is being developed.
• Assembler: assembled program usually distributed for general use.

Question 11

Compiler advantages

Answer 11

• Original source code is hidden, preventing program from being copied
• Compiled programs can be run without the compiler
• Compiled programs take up less space in memory when executed
• Compiled program is executed in a shorter time

Question 12

Compiler disadvantages

Answer 12

• Takes a longer time to write, test and debug program during development

Question 13

Interpreter disadvantages

Answer 13

• Programs cannot be run without the interpreter
• Programs can take longer to execute

Question 14

Integrated development environment (IDE) meaning

Answer 14

Software that consolidates basic tools required to write and test programs to make a programmer’s journey effective and useful.

Question 15

IDE Features

Answer 15

• Auto-completion
• Auto-correction
• Error diagnostics
• Translators (compiler/interpreter)

Question 16

How assembler translates a program

Answer 16

• Translates a low-level assembly language program into machine code.
• An executable file is produced
• Assembled programs are run without the assembler.

Question 17

Interpreter advantages

Answer 17

• Easier and quicker to debug programs during development
• as errors are immediately reported when detected

Question 18

Advantages of low-level language

Answer 18

• More efficient use of memory
• Allows for direct manipulation of hardware
• Takes up less storage space
• Can use special machine-dependent instructions

Question 19

Whats a high level language

Answer 19

A programming language that makes use of English like statements. which need to be translated to machine code
