Computing- Flowcharts,arithmetic
operators, variables, hardware and
software
- FLOWCHARTS
- THERE ARE DIFFERENT SHAPES TO
REPRESENT EACH STEP IN A
FLOWCHART
- Picture representation of an
algorithm

FLOWCHART
- Variables
- A variable is a location in a memory in
which you can temporarily store texts
or numbers
- Data types- integers, characters,
string, float(decimal), Boolean.
- The way in which data is stored in a computer
- equal in python is writen as ==, not
equal to in python is written as ! =
- The way in which data is stored in a computer
- Data is input by a
user into a variable
- A variable is a location in a memory in
which you can temporarily store texts
or numbers
- Arithmetic operations
- MOD- Remainder 23 MOD 5 =3 (This is
because when you divide 23 by 5 the
remainder is3)
- MOD is written as % in python. you
can use it to see if a number is even

- Hardware and Software
- A computer system is made up of
hardware and software
- Hardware is any physical
component that makes up the computer
- Software is any program that runs
on a computer
- There are two types of
software-system software and
application software
- System software-Programs that are needed to
enable the computer to function, For example,
an operating system such as Windows
- Operating Systems
- Software that manages a computer's hardware and provides
a user interface, some operating systems are iOS, Windows,
Linux
- Functions: Provides a user interface,manages how programs use main
memory, allows processor management,manages peripherals,mangaes
applications, provides security
- Software that manages a computer's hardware and provides
a user interface, some operating systems are iOS, Windows,
Linux
- Utility software
- Utilities provide extra functionality, utilities can be grouped into
categories which are computer security, file organisation and
system maintenance
- Utilities provide extra functionality, utilities can be grouped into

- Operating Systems
- Application Software-Programs that are
needed to perform tasks for the user For
example, word processing software
(Microsoft Word)
- System software-Programs that are needed to
enable the computer to function, For example,
an operating system such as Windows
- There are two types of
software-system software and
application software
- Hardware is any physical

- A computer system is made up of
hardware and software
- Pseaudocode
- closer to actual
programming language
- Pseudo code is a kind of structured
English for describing algorithms
- allows the programmer to focus on the logic of the algorithm
without being distracted by the syntax of the programming language
- closer to actual
programming language
- an arrow next to a variable means that its
assigned to something e.g mealcost⬅️4.00
- An IF statement is a selection statement.The next statement to be
executed depends on whether the condition being tested is true or
false
