Classification of programming languages

............ converts high level languages into machine code one instruction at a time on-the-fly while the program is running. Each instruction is converted to machine code once the previous instruction has been executed.

• Compiler

• Interpreter

• Assembler

............ is a program that converts high level languages into machine code before the program is run. A compiler saves the machine code, so the source code is no longer needed A compiler allows a program to be run faster  that interpreted code. 

• Compiler

• Interpreter

• Assembler

............ converts assembly language instructions into machine code. 

• Compiler

• Interpreter

• Assembler

A high level language .......

• use mnemonics

• are easier to understand

• Needs a translator

• run slower because of the layers of abstraction and there is inefficiency in translator.

A low level language ......

• are very difficult to understand and modify

• is written for a specific processor architecture, and so is not portable to other computer architectures

• are appropriate for developing new operating systems, embedded systems and hardware device drivers

• are easier to understand

Machine code ....

• is expressed in binary values 0 and 1.  

• is specific to a processor.

• are made up of two parts the operator and the operand.

• is portable

Interpreters ....

• convert each instruction is to machine code once the previous instruction has been executed. 

• converts high level languages into machine code one instruction at a time on-the-fly while the program is running

• are good for debugging code because the program stops as soon as the error has been found.

• saves the machine code, so the source code is no longer needed

Python is a high-level programming language

• True

• False

Python code uses interpreter to convert it into machine code one instruction at a time on-the-fly while the program is running.

• False

• True
