Unit 1.6 Software Engineering

Which of the following is NOT a reason programmers prefer high level languages?

• Easier to understand

• Resemble pseudo-code

• Require more processing power

• More portable

What can be executed directly by the CPU?

• High-level languages

• Machine code

• Assembly code

• Source code

Henry is learning about computer programming and wants to know which of the following does not need conversion to be executed by the CPU?

• High-level languages

• Assembly code

• Machine code

• Source code

What is the primary characteristic of machine code?

• It is human-readable

• It is written in bit patterns

• It is easy to debug

• It is platform-independent

Why do high-level languages need conversion before execution?

• They are too complex

• They are not in bit patterns

• They are already in machine code

• They are written in binary

For what type of CPU are program statements in assembly language written?

• Any type of CPU

• A specific type of CPU

• Only for Intel CPUs

• Only for AMD CPUs

What do program statements in assembly language make direct reference to?

• External devices

• Specific internal registers of a processor

• Network protocols

• User interfaces

What is a characteristic of high level languages?

• They are used for fast execution speeds

• They are used in embedded systems

• Execution speed is not critical

• They are used in device drivers

What is the main advantage of using high-level languages over assembly language?

• Faster execution

• Platform independence

• Direct hardware access

• Lower memory usage

Which of the following is a disadvantage of machine code?

• It is difficult to debug

• It is human-readable

• It is easy to write

• It is platform-independent
