Introduction to Programming Languages

What is a high-level programming language (HLL)?

• A language that uses 1s and 0s to communicate with the CPU

• A language that is easy for humans to read and write

• A language that is directly executed by the CPU

• A language that only works on one type of processor

Why do programmers use high-level languages?

• They are portable and can run on any CPU

• They are difficult to read and understand

• They execute faster than low-level languages

• They use binary code directly

What is machine code?

• A type of high-level language used in software development

• A sequence of binary instructions that the CPU can execute directly

• A set of instructions written using English words

• A graphical programming language like Scratch

What is the role of the CPU in executing programs?

• It translates high-level languages into English

• It executes machine-code instructions

• It converts assembly code into Python

• It writes code for the programmer

Which of the following is NOT a characteristic of high-level languages?

• Easy for humans to read, write, and modify

• Uses variable names instead of memory addresses

• Requires an assembler to execute

• Portable across different CPUs

Why is a low-level language (LLL) harder for humans to read?

• It uses English-like syntax

• It directly references memory addresses

• It does not use variables

• It is executed more slowly

What makes high-level languages more user-friendly than low-level languages?

• They are written in binary

• They do not require a translator

• They use words and symbols familiar to humans

• They execute instructions faster than machine code

How does assembly language compare to machine code?

• Assembly language is easier for humans to understand

• Machine code uses symbols instead of binary numbers

• Assembly language does not require translation before execution

• Assembly language runs faster than machine code

Which statement about assembly language is true?

• It requires an interpreter to run

• It uses symbols instead of binary for instructions

• It is the same as machine code

• It cannot be executed by any CPU

What does an instruction in assembly language correspond to?

• Multiple machine-code instructions

• A single machine-code instruction

• A single line of high-level code

• A complete program
