00:00:02.760 --> 00:00:07.500 align:middle line:84%
Computers work with inputs,
processes, and outputs.

00:00:07.500 --> 00:00:12.820 align:middle line:84%
An input is data entered into
or received by a computer,

00:00:12.820 --> 00:00:17.100 align:middle line:84%
such as a keypress, mouse
click, or sensor reading.

00:00:17.100 --> 00:00:19.950 align:middle line:84%
Inputs can give
instructions to a computer

00:00:19.950 --> 00:00:23.250 align:middle line:84%
or provide data to
process, but inputs don't

00:00:23.250 --> 00:00:26.040 align:middle line:90%
need to be initiated by people.

00:00:26.040 --> 00:00:28.500 align:middle line:84%
For example, a
temperature sensor

00:00:28.500 --> 00:00:32.280 align:middle line:84%
could gather and input
data into a computer,

00:00:32.280 --> 00:00:34.620 align:middle line:84%
or a message could be
wirelessly received

00:00:34.620 --> 00:00:38.830 align:middle line:84%
by a computer from
another device.

00:00:38.830 --> 00:00:43.150 align:middle line:84%
A process determines what a
computer does with an input,

00:00:43.150 --> 00:00:47.420 align:middle line:84%
but the same input can be
processed in different ways.

00:00:47.420 --> 00:00:51.610 align:middle line:84%
For example, pressing the
A key on your keyboard

00:00:51.610 --> 00:00:55.990 align:middle line:84%
will display the letter A when
using word processing software,

00:00:55.990 --> 00:00:59.380 align:middle line:84%
or it could be a directional
control for moving

00:00:59.380 --> 00:01:02.350 align:middle line:90%
a character in gaming software.

00:01:02.350 --> 00:01:05.860 align:middle line:84%
A program contains the set
of instructions that define

00:01:05.860 --> 00:01:07.600 align:middle line:90%
the process.

00:01:07.600 --> 00:01:10.330 align:middle line:84%
The output is how
the computer presents

00:01:10.330 --> 00:01:13.480 align:middle line:84%
the results of the
process, such as text

00:01:13.480 --> 00:01:18.890 align:middle line:84%
on a screen, printed materials,
or sound from a speaker.

00:01:18.890 --> 00:01:22.250 align:middle line:84%
Young learners don't need to
know how the computer processes

00:01:22.250 --> 00:01:24.980 align:middle line:84%
the data but should be
aware of something happening

00:01:24.980 --> 00:01:27.890 align:middle line:84%
between entering the
input into the computer

00:01:27.890 --> 00:01:30.440 align:middle line:90%
and producing the outputs.

00:01:30.440 --> 00:01:37.120 align:middle line:84%
The process might be Make
It Bigger, Double It,

00:01:37.120 --> 00:01:43.710 align:middle line:90%
Turn On, or Turn Off.

00:01:43.710 --> 00:01:46.680 align:middle line:84%
As your pupils develop the
understanding of how computers

00:01:46.680 --> 00:01:50.610 align:middle line:84%
work, you can reflect on the
inputs, processes, and outputs

00:01:50.610 --> 00:01:53.500 align:middle line:90%
of everyday digital devices.

00:01:53.500 --> 00:01:54.990 align:middle line:90%
Think about your day.

00:01:54.990 --> 00:01:57.540 align:middle line:84%
How many times have
you used a computer?

00:01:57.540 --> 00:02:01.500 align:middle line:84%
What were the inputs, processes,
and outputs of those devices?

00:02:01.500 --> 00:02:04.820 align:middle line:84%
