All language subtitles for 1_CPU

If someone asked you,
calculate the square root of

5,000,439,493 would you
do the math by hand?

Unless you really love
tedious math problems,

you'd probably use a calculator.

What about binary? Well,

you probably wouldn't calculate
binary by hand either.

There's actually a very
powerful calculator

right inside of your computer,

that process binary for us.

We've already discussed
this in calculator

in detail. Do you
know what it is?

It's our CPU, the
brain of our computer.

In this video, we'll cover

the more practical
aspects of the CPU.

Remember that
transition book that I

talked about in an
earlier lesson?

The CPU uses this to

translate and perform
functions on our data.

This translation book is
called an instruction set,

which is literally
just a list of

instructions that our
CPU is able to run.

Functions like
adding, subtracting,

copying data are
all instructions

that our CPU can carry out.

Every single program on

your computer, while
extremely complex,

is broken down into very
small and simple instructions

found in our instruction set.

Instruction sets
are hard-coded into

our CPU so different
CPU manufacturers

may use different
instruction sets,

but they generally perform
the same functions.

It's like how car manufacturers

build their engines differently,

but they all get
the same job done.

You probably worked with

computer hardware as an
IT support specialist,

replacing failed hard disks,

upgrading RAM modules, and
installing video cards.

You need to be aware
of what's out there.

You've probably heard of

a few popular CPU
manufacturers or chipsets,

like Intel, AMD, and Qualcomm.

These CPU manufacturers use

different product names to
differentiate their processes.

Like Intel Core i7, AMD Athlon,

Snapdragon 810,
Apple A8, and more.

Now when you hear these terms,

you'll know what they mean.

Each of these CPU manufacturers

have their strengths
and weaknesses.

If you're interested in
learning more about why

some CPUs are more
popular than others,

you can check out the next
supplemental reading.

When you select your CPU,

you need to make sure it's

compatible with
your motherboard,

the circuit board that connects

all your components
together, heads up.

You can't just buy a bunch of

parts and expect them
to work together

there are different
ways of CPUs fit

on motherboards using
different sockets.

Your CPU might have lots of
tiny pins that are either

stick out or have contact
points that look like dots.

Depending on your motherboard,

you need to make sure

these CPUs fit correctly
in the socket.

There are currently
two major types of

CPU sockets; Land Grid Array,

also known as LGA,

and Pin Grid Array,

also known as PGA.

In an LGA socket,

like this one, there are pins

that stick out of
the motherboard.

The socket size may vary,

so always make sure your CPU and

socket are compatible
beforehand.

When you purchase a
CPU or motherboard,

they'll tell you
right on the box

what type of socket it has.

Make sure your CPU and

motherboards socket
also both match.

If it's not listed on the box,

you can go to the manufacturer's

website where you usually

list what types of

CPUs are compatible
with the motherboard.

The other type of socket
is the PGA socket,

where the pins are located
on the processor itself.

When we installed our CPU,

we need to do a few things
to it to keep it cool.

Since it does a lot of work,

it's prone to overheating.

We have to make sure to include

a heat sink too which takes

the heat from our
CPU and dissipates

it through a fan
or another medium.

There's one last thing I
want to call out about CPUs.

If you purchase the CPU,

you'll see that it has

either a 32-bit or
64-bit architecture.

What does that mean? Well,

we know we can process
eight bits in binary now,

imagine how we can process
with 32 or even 64 bits.

CPUs that have 32-bit or

64-bit architecture are just

specifying how much data
they can efficiently handle.

For now, the main
takeaway is that

the CPU is one of the
most important parts of

the computer so we have to
make sure it's compatible with

all other components and can

perform well for our
computing needs.
