Pearson 1CP2 - 3.3 - Programming Languages

What level of language is comprised of instructions stored as binary 1s and 0s (often referred to as machine code)?

• High-level language
• Assembly code
• Machine code
• Low-level language

What is the name of the low level language that is made up of binary 1s and 0s?

• Machine code

• Digital language
• Zero-One language
• Binary code

The instructions a CPU can execute are often referred to as an...

• instruction set
• operation set
• command set
• task set

Why is machine code hard for humans to work with?

• Machine code comprises thousands of 1s and 0s. It is hard to identify individual instructions or mistakes

• Machine code does not require a processor to execute.
• Machine code is easily readable by humans.
• Machine code is written in a high-level programming language. This requires learning lots of key commands.

What level of language is commonly used by programmers to write software?

• low-level language
• medium-level language
• basic language
• high-level language

What is an example of a low level language that isn't machine code?

• Java
• C++
• Python
• Assembly language

What are the individual instructions of Assembly Language referred to as?

• syntax
• mnemonics
• procedures
• commands

In Assembly Language, what is a mnemonic?

• A mnemonic is a type of computer virus
• A mnemonic is a type of computer hardware that is responsible for translating high level code into Assembly Language

• A mnemonic is a type of computer software that executes machine code on older computers

• A mnemonic is a (usually) 3 letter Assembly Language code that represents a binary instruction

A disadvantage of Assembly Language is...

• limited range of instructions so lots of small instructions needed for a simple sequence

• difficult to learn because the sheer number of available mnemonics is astounding

• limited functionality due to not being able to work with more modern CPUs

• high-level and very portable, which means it is more preferable to work with than even C# or Python

What is meant by bare metal programming?

• Writing code that interacts directly with hardware without an operating system
• Developing software applications for mobile devices
• Writing code that only works on virtual machines
• Using high-level programming languages with no hardware interaction
