What is assembly language?

• A low-level programming language that uses mnemonic codes to represent machine instructions.

• A language used for creating graphical user interfaces.

• A programming language that is only used for web development.

• A high-level programming language that uses mnemonic codes to represent machine instructions.

Answer explanation

Assembly language is a low-level programming language that uses mnemonic codes to represent machine instructions. It is not used for creating graphical user interfaces or for web development exclusively. Also, it is not a high-level programming language. The mnemonic codes in assembly language correspond directly to the machine language instructions of a specific CPU architecture.

Name one advantage of using assembly language.

• Higher level of abstraction

• Platform independence

• Efficient execution of code

• Easier debugging of code

Answer explanation

The question asks for an advantage of using assembly language. The correct answer is 'Efficient execution of code'. Assembly language is closer to machine code, which allows for more efficient execution of code compared to higher-level languages. Other options like 'Higher level of abstraction', 'Platform independence', and 'Easier debugging of code' are generally not advantages of assembly language.

What are assembly language instructions?

• Low-level instructions executed by a computer's CPU.

• Instructions executed by a computer's RAM.

• Instructions executed by a computer's GPU.

• High-level instructions executed by a computer's CPU.

Answer explanation

Assembly language instructions are low-level instructions that are directly executed by a computer's CPU. They are not executed by the RAM or GPU, nor are they high-level instructions. These instructions are closer to machine code and provide more control over the hardware, which differentiates them from high-level instructions.

How many registers are there in assembly language?

• 1

• 10

• 100

• No fixed number

Answer explanation

The number of registers in assembly language is not fixed. It varies depending on the specific architecture of the computer system. Some systems may have a few registers, while others may have many more. Therefore, the correct answer is 'No fixed number'.
