Computer Science

a language that replaces machine code with short, readable instructions to make it easier for humans to write and understand

a program written using 1s and 0s that a computer can execute directly

Assembly language

High and low level languages

Features of an IDE

Input and output

Developing programs using sequence

Variables and constants in programs

Common data types

Programming project: sequence I

Programming project: sequence II

In this unit pupils will discover computers process instructions. They will recognise the function and tools IDEs provide for developing code and start to develop Python programa which follow a sequence. Pupils will create programs which deal with input and output and make variables to store values.

Programming: sequence

a markup language used to design web pages

a low-level programming language that uses short, readable instructions

What is the term for a program written using 1s and 0s that a computer can execute directly?

It’s used for applications that need direct hardware control (embedded systems).

It’s the easiest language for beginners to learn.

It’s faster than all other programming languages.

Why is assembly language still relevant today?

Assembly language uses short instructions and machine code is written in binary.

Machine code is human-readable, while assembly language is not.

Assembly language is faster than machine code.

Machine code is used only in modern computers.

What is the main difference between machine code and assembly language?

Place the following languages in order of abstraction (lowest to highest).

executed directly by the computer’s processor

used for general-purpose programming, such as creating applications

a language that only works on web browsers

a language that uses natural language to write code

a language that provides direct control over hardware

a language that is easy for humans to read and write

What is a low-level programming language?

a language that uses abstraction to make programming more human-readable

a language that directly controls hardware

a language that doesn’t require translation

What is a high-level programming language?

to translate high-level code into machine-readable code

converts code into a complete executable file

translates and executes code line by line

Which of the following is an example of a low-level language?

Arrange the steps in writing and running a program in a high-level language.

Assembly language
