let's learn about what's on the inside

of a computer this was a standard

desktop computer and it has a nice and

easy lift up lid and let's look at some

of the parts inside the computer first

of all this part right here is where the

electricity comes in this is called the

power supply the power supply converts

the alternating current into direct

current and the wires come out on the

side we can't really see it though so

let's see if we can take some of this

stuff out just real quickly as a preview

the CPU is right here the RAM memory is

right there the hard drive storage is

right here and the optical drive is

right here the mainboard is the green

part inside there alright so now let's

take a look and see if we can take out a

few parts and see what they are first of

all sometimes when using a computer you

might find that you're running out of

storage and you need more storage you've

got so many videos and pictures and

things that your storage is all filled

out this is the hard drive this

particular hard drive has 500 gigabytes

of storage space so that's quite a lot

but again videos can use up a whole lot

of storage space it's possible to have

more than one hard drive inside a

computer or you could replace a hard

drive you could replace a 500 gigabyte

one with a one terabyte drive or a two

terabyte drive or even a four terabyte

drive there's a lot of choices you'll

notice this drive has two cables

connected to it it has a data cable and

it has a power cable those two cables

are the only two cables really needed to

connect it to the computer itself I'm

gonna set that to the side I'm gonna

also open up this this is where the

compact disk drive actually it's a DVD

drive also it's just called an optical

drive so this Drive has the same couple

of ports it's got a data port just here

and it's got a power port right here and

this is about how simple of this two

acts

remove these drives they might have a

couple screws on the side that are

holding them in place but for the most

part pretty simple to replace the drive

suppose you had a disk drive you notice

it wasn't working for whatever reason

you could easily get a new disk drive

and put it in you would have to install

some new software though because

hardware only works when it has the

correct software so we'll put that back

in there put the data cable back on and

put the power cable back on actually I

said those wrong this is the power cable

and this one is the data cable now the

way we know which cable is which is

because we look at the power supply and

you'll see out of the power supply

there's coming several cables these are

what is powering the computer so this

cable right here you can see that's

going over here into the mainboard

that's what's powering the mainboard

including the central processing unit

but it's only powering the green board

and the things that are really really

connected clearly the optical drive has

to have its own power so here's here's

its power cable and the hard drive which

is up here has to have its own power

which is right here actually if I look

closely enough I can see that this is

not actually the power that goes to the

main board because this larger socket

here is the one that provides the power

to the main board so I'm guessing that

this is maybe something different maybe

it's providing power to the video card

better plug those back in I want to make

sure this computer is still working

after we're done here so the power comes

in to the main board and from the main

board it can go to the drives and

whatever else needs power the data

cables you'll notice the data cables are

coming over here so there's the data

cable that is bringing information to

the hard drive and from the hard drive

back to the main board there's also a

cable here which is going to the optical

drive

inside a computer there's something

called memory memory is only active when

the computer is on while hard drives

work this 500 gigabyte hard drive will

save information it has information on

it right now even though the computer is

unplugged the RAM memory only has

information in it when the computer is

off now these cards are super easy to

take out with these little wipe tabs you

just push them apart and then the card

kind of slides up a little bit and I'll

give you a good look at it so this is

called a memory card and the memory card

has some memory chips on it it looks

like it has eight chips and if you look

really closely at the label it says this

is a four gigabyte card four gigabytes

that's the random access memory now

since they're eight chips on there and

there's no chips on the other side each

chip must be half a gigabyte worth of

storage now you'll notice that this

computer has actually oh and something

important when you're putting memory

into a computer there's a slot along the

edge here there's probably 64 little

metal pins there may be 128 64 on each

side but that little slot shows you how

to put it into the computer so you can

see there's the little slot there you

need to put that in just here and we're

gonna put it in the same exact slot it

was in before and it snapped now what if

I want what if I was noticing my

computer was slowing down when I had

lots of tabs open or when I was using

several programs at the same time a good

thing to try would be to add an

identical memory card in the other blue

slot so I'd have to check and see

exactly what is this brand what are all

the code numbers on there buy one

exactly the same or find one exactly the

same put it in the blue slot could even

put in four memory cards instead of one

then instead of having 4 gigabytes we'd

have 16 gigabytes of ram memory now the

nice thing about ram memory is it's

super fast and it's connected by some

wires directly to the central process

you know so when the central processor

needs information instead of trying to

access it all the way through the wires

into the optical drive or the hard drive

it can just grab it off the RAM the

random access memory so right here

you'll notice there's a fan so why is

there a fan there because underneath the

fan and underneath that piece of metal

which is called the heatsink is the

processor the central processing unit

that does all the calculations and does

most if not all of the work of the

computer now some computers will have a

second processor just to make the

picture on the screen and that's called

a video processor but for the most part

the central processor is what we

consider to be the most important

processor now you'll notice there's some

screws here the reason there's some

screws here is sometimes maybe the fan

will stop working it'll fail so you

could replace the fan underneath

sometimes the processor will either stop

working or it's just been several years

and the processor just isn't as fast as

we want you can buy a new processor that

fits in exactly the same spot and then

your computer will go faster but you

have to make sure it's exactly the same

numbers on that processor the same type

of processor so for example if you're

getting a core seven processor if that's

what's in it right now then you'd have

to replace it with another core seven

processor I see some other wires here

looks like these wires might be the ones

that are powering up it looks like

they're going to the front of the

computer looks like they're powering

this fan in the front again we need to

make sure to keep everything cool the

processor will get very very hot

especially if you're using a lot of

programs at the same time or maybe

you're doing something like creating a

video that that uses lots and lots of

process or energy it causes the

processor to get very hot so there's a

fan there's also a little tiny speaker

over here that's called the personal

computer speaker which is abbreviated PC

speaker

you'll notice there's another heatsink

right here there's probably something

else that gets really super hot right

underneath there and we could probably

push those pins and take it out and see

what that is you'll notice something

round right here this is the clock

battery the clock battery makes sure the

clock keeps running so even though this

computer's not plugged in that clock

there's a clock chip maybe it's that

little chip right there and that clock

chip keeps the clock running well the

battery keeps the clock running if this

computer were unplug unplugged for a

long time like a year or two or maybe

more years eventually the battery of

course would drain and the clock would

not be working anymore that means that

every time you turn down the computer

you'd have to reset the clock or maybe

the computer wouldn't turn on at all

because maybe the clock is required for

the computer to turn out in the back of

the computer are the port's where things

plug into you can see that there's some

different little boxes where the ports

are housed there's the USB 3s over here

and the USB 2 and the network port here

there's also like a video port right

there and there's a display port there

you'll notice over here there are

one-two-three-four expansion slots and

one of the expansion slots is taken up

by two more USB ports and those USB

ports are plugged into this little spot

right here

you might notice these two white slots

well suppose you wanted to do some video

gaming or do something really really

fast with the computer like video

processing like making videos high

definition or Ultra High Definition you

would maybe put in a brand new card it

would look green like this and it would

be a video card and it would stick out

the back so you could plug in your

monitor a lot of times people that game

on computers will have another video

card or even two video cards there's

also two more little black slots those

can also be used to make more ports on

the back of the computer so maybe

there's something you want to add like

maybe you want wireless networking on

this computer right now it doesn't have

any

but you could add a card they had an

antenna in the back and have Wi-Fi in

this computer so there's one two three

four slots where you could add something

onto the computer so that's the quick

tour of the inside of a computer now

many of these things can be replaced and

some of them can't be replaced you could

replace the mainboard if something was

wrong with the mainboard

you could replace the memory or you

could add more memory you could replace

the fan you could replace the processor

if the power supply stopped working you

could place the power supply the optical

drive maybe you want to put in a blu-ray

optical drive well you saw how easy it

was to put in this optical drive if you

want to replace the hard drive and put

it in a hard drive that has more

capacity you can see that would be

pretty simple to do maybe one of the

fans is burned-out you could replace the

fan on the front of the computer and of

course you could even add stuff to the

computer like adding more ports on the

back so these computers are called

expandable it's not like a phone or a

tablet computer where usually the only

thing you can expand is maybe adding a

little more storage like a memory card

desktop computers have lots of space

where you can upgrade them so that they

can do more things than they did when

you originally purchase them and you can

easily replace things yourself if they

go bad I hope you've enjoyed this quick

tour of the inside of the computer to

help you remember this maybe you want to

take a picture of the inside of computer

and label all the parts that might help

you remember thank you very much I hope

you've enjoyed this a lot
