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.
