the back of most PCS is this huge Festival of different ports and
connectors and we just realized we've never done an episode explaining what
they all are which is honestly kind of wild because some of these are pretty
Nostalgia inducing at this point now let's start out with these multicolored
connectors these are all for audio so why are there so many well a typical
pair of PC speakers will plug in to that green port with the pink one being for a
microphone and the blue one being a line in if you want to connect an input
device that's not a microphone is that clear no microphones some PCS will have
three additional ports one for a center speaker or subwoofer one for side
speakers and one for rear speakers if you have a more traditional surround
sound setup that doesn't use a digital connection but if you do have something
like an external AV receiver or an external Dack that bypasses your
computer's built-in Sound Processing you can connect those here it's called a
toss link connector and it uses an optical signal hence why you can often
see light shining out of it next let's talk networking this guy is an Ethernet
port which on most modern systems supports a connection of at least 1 gbit
per second you'll typically use this port to connect to your router and get
on the internet and it's also usually the only port to have indicator lights
on it what those lights mean depends on the model but it's fairly common for one
light to indicate activity and another to indicate link speed so check your
manual for the juicy details and these two screw connectors on some systems are
for your Wi-Fi antennas some desktops and motherboards include these so you
don't have to depend on having a router or an Ethernet wall jack nearby just
screw the antenna in and you should be good to go although you may need to
install a driver afterwards let's move on and talk about an older Port that's
still somewhat common on Modern systems this guy is called a PS2 port and was
what most of us used to connect keyboards and mice before USB came along
older systems often had a purple port for keyboards and a green port for mice
but modern systems that still feature PS2 often combine them into one port
where you can plug in either device now there isn't too much reason to use PS2
these days on your home PC but it can at least free up a USB port for other
devices speaking of USB we're going to tell you all about how it's implemented
on current systems right after we thank our sponsor delete me online privacy

and Safeguard your family's digital world today USB has been around since
the '90s and was developed to be a many things in one kind of port and it's
largely succeeded at this if you're plugging in something other than a
monitor analog audio equipment or an Ethernet cable there's a very good
chance you're using USB you can connect things like printers webcams keyboards
mice streaming accessories and even miniature Christmas trees over USB but
do keep in mind that all USB ports are
not the same a modern desktop PC might have USB ports that support various data
transfer rates different char charging speeds or other features like updating
your computer's firmware without booting it up these features will often be
colorcoded for example usb3 ports that support 5 gbit per second speeds are
often blue but again check your PCS or motherboards manual to figure out
exactly what's what especially as there isn't always consistency between
manufacturers and some companies even just make all their USB ports the same
color for a signature look PCS are also increasingly coming
with these USB type-c ports allowing you
to use newer USBC cables and on laptops
they're often used for charging as well some USBC ports also support the
Thunderbolt protocol which enables specialized applications like connecting
external graphics cards now let's wrap things up by talking about monitor
connections modern systems typically come with one or both of these ports
this one is simply called DisplayPort
and this other more symmetrical one is HDM Mii you know just like you probably
have on your TV there are some small differences between the two ports but
for most typical use cases you can just use whichever one your monitor supports
they also both carry audio signals allowing you to use your monitors
built-in speakers or an external receiver if you so desire and that's
everything you'll usually find on the back of a modern PC but if you want to
know more about some of the ports that USB replaced not so long ago and that
you can actually still find on some Modern systems such as VGA and DVI go
