All language subtitles for 4. Course Introduction

On July 20th, 1969,

one of the most phenomenal events

made his way into the history books.

When the Apollo 11 completed
its historic mission to the moon.

Although the most
brilliant minds helped to

make sure that the Eagle had landed,

computers also played
a significant role.

The guidance system that
navigated the spacecraft was

one of the earliest forms
of modern computing.

That same computer,
the one that helped

America's lunar dreams
become a reality,

took up the space of
an entire room and

had one-10,000th the computing

power of the thing that
almost everyone of

you carry in your pockets
today, a smartphone.

Computer hardware and
software have had

such a dramatic evolution that what

was once only used to power rockets,

now shapes the entire way
our world functions.

Think about your day,
did you grab a snack?

Turn on your TV?

Take a driving in your car?

Computers were along
for the ride literally,

computers are everywhere.
So, here's the rundown.

By the end of this course,
you'll understand how computers

work and get a grasp of
the building blocks of IT.

We're going to cover
the basics of how

computer hardware
performs calculations,

and we're going to actually build
a computer from the ground up.

We'll look at how operating

systems control and
interact with hardware,

we'll take a look at
the Internet and get

a better understanding of how
computers talk to each other.

We'll also spend time
learning about how

applications and programs
tie all of this together,

and let humans interact
with these systems.

Finally, we'll cover
important lessons

on problem-solving with computers,

and cover the communication
skills that are so

critical when interacting
with others in IT.

Whether you're looking for a job
in the IT industry or you just

want to learn higher laptop
connects to the Internet,

understanding how computers
work at every level

can help you in your day-to-day
life and in the workplace.

But first, let's take
a step way back,

back to where all begin,

even before the Apollo
11 mission touchdown so

you can understand how and
why we use computers today.
