Computer Science

programming languages that require the programmer to use terms that are aligned to the operations of a specific machine

a human-readable language written in formal, structured English

creates an executable file for a program by translating a high-level language to machine-readable code

translates and executes code line by line, then translates it into machine-readable code

High and low level languages

Assembly language

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

they use abstraction to simplify programming

they provide direct control over hardware

What is a key characteristic of low-level programming languages?

it is easier for humans to read and write

What is one reason to use a high-level programming language?

Which type of language is most likely used to write an operating system?

to rewrite low-level code into high-level code

to translate high-level code into machine-readable code

Translates code into machine-readable code line by line.

Rewrites low-level code into high-level code.

Why might a programmer choose a low-level language over a high-level language?

When following a recipe, why is it important to follow the steps in order?

What is the purpose of a translator in real life?

What happens if you give vague instructions to a robot?

Why is it easier to read a book written in plain English rather than one in a foreign language?

What is a set of ordered commands that a computer can run to complete a task?

What system do computers use to store and process all data and instructions?
