00:00:00.080 --> 00:00:07.839
do you ever wonder why nearly every external device you connect to a PC uses

00:00:04.480 --> 00:00:09.320
a USB port the simple answer is because

00:00:07.839 --> 00:00:13.920
that's a lot better than the way it used to be before USB was around we had a

00:00:11.599 --> 00:00:17.320
whole Litany of Port types So today we're going to show you just how

00:00:15.440 --> 00:00:21.359
annoying it could be to connect your electronics back in the 80s and 90s

00:00:19.760 --> 00:00:26.400
let's start out with a port some of you might still be familiar with today the

00:00:23.480 --> 00:00:31.519
PS2 Port this chocolate chip cookie looking little guy was introduced not

00:00:28.519 --> 00:00:34.800
with the PlayStation but in 1987 on the

00:00:31.519 --> 00:00:37.440
IBM personal system SL2 it replaced an

00:00:34.800 --> 00:00:41.640
older connector called the din which was originally an audio connector from the

00:00:39.239 --> 00:00:47.320
1950s but was used as the keyboard connector on the original IBM PC as well

00:00:44.239 --> 00:00:50.280
as a tape drive connector on the IBM PC

00:00:47.320 --> 00:00:55.800
junor which was like the IBM PC but more naive once PS2 took over it was common

00:00:53.559 --> 00:01:00.120
for systems to include two of them one for your keyboard and one for your mouse

00:00:57.800 --> 00:01:04.920
and color code them purple and green respectively since each Port was often

00:01:02.440 --> 00:01:09.799
coded at a low level to only work with that specific

00:01:07.000 --> 00:01:13.720
device the PS2 Port was useful back in the day because it provided a dedicated

00:01:11.720 --> 00:01:18.080
link on the motherboard for mice something older systems didn't always

00:01:15.479 --> 00:01:22.439
have but seeing as how USB provided an equally easy way to connect them PS2

00:01:20.560 --> 00:01:27.000
ports aren't that common anymore especially as their pin base design made

00:01:24.920 --> 00:01:32.720
them more fragile than the typical USB port and they're not technically meant

00:01:29.119 --> 00:01:34.280
to be hot popped however PS2 ports can

00:01:32.720 --> 00:01:38.399
still be found on some Modern motherboards usually as a combined

00:01:36.560 --> 00:01:42.000
keyboard and mouse port and that's because they do still have some

00:01:39.880 --> 00:01:47.439
advantages PS2 tends to work more reliably with some older bioses and in

00:01:44.759 --> 00:01:51.600
settings where security is Paramount PS2 ports allow an organization to just

00:01:49.240 --> 00:01:55.520
disable all USB ports on their computers to ensure people aren't connecting

00:01:53.079 --> 00:01:59.000
things like unauthorized flash drives but the PS2 connector wasn't the only

00:01:57.479 --> 00:02:04.520
connector for keyboards and mice during the late 80s this thing is called the

00:02:01.680 --> 00:02:09.759
Apple desktop bus found on Apple system starting in 1986 but it supported more

00:02:07.520 --> 00:02:15.440
peripherals like joysticks and Graphics tablets and could even be Daisy chained

00:02:12.520 --> 00:02:18.959
but this port too was replaced by USB once the original iMac came out but

00:02:17.400 --> 00:02:22.280
let's move on from keyboards and mice and talk about what the heck these

00:02:20.519 --> 00:02:27.959
things are right after we thank the sponsor of this video Cloud DNS Cloud

the link below it's that easy instead of

00:03:07.040 --> 00:03:13.400
being intended for a specific use like the keyboard and mouse ports we've

00:03:10.519 --> 00:03:18.879
discussed this guy was kind of the OG doit all connection it's called a Serial

00:03:16.200 --> 00:03:24.480
port and just like today's USB ports it sent or received data one bit at a time

00:03:22.680 --> 00:03:27.680
serial ports were used for all sorts of things not only could you connect a

00:03:26.080 --> 00:03:32.400
mouse to them but people use them for modems routers PC to PC connections

00:03:30.400 --> 00:03:37.760
uninterruptable power supplies text displays and even old school smart home

00:03:35.360 --> 00:03:41.840
hubs although the serial Port can still be found today in some specialized

00:03:39.760 --> 00:03:47.239
applications older implementations of the port were quite Limited in real

00:03:44.000 --> 00:03:49.599
world speed to around 9600 bits per

00:03:47.239 --> 00:03:56.079
second which in addition to its clunky design contributed to its downfall and

00:03:52.159 --> 00:03:58.319
the rise of USB now this big chunker is

00:03:56.079 --> 00:04:04.280
called a parallel port also more specifically known as a printer port or

00:04:00.519 --> 00:04:06.760
1284 port and was typically labeled lpt

00:04:04.280 --> 00:04:10.680
followed by a number in Windows as the name suggests it was mainly used for

00:04:08.640 --> 00:04:14.760
connecting printers and was fairly ubiquitous for this purpose during the

00:04:12.400 --> 00:04:18.479
1990s although there were some printers that could connect through the

00:04:16.000 --> 00:04:22.479
aforementioned serial Port the parallel port became more popular because it

00:04:20.400 --> 00:04:29.120
could deliver both data and control signals to the printer at the same time

00:04:25.800 --> 00:04:31.320
what technology a few other data heavy

00:04:29.120 --> 00:04:35.880
devices including Optical drives zip drives and even a few MP3 players also

00:04:33.960 --> 00:04:40.120
used the parallel port because it could move more data than the serial Port

00:04:38.479 --> 00:04:44.800
however it still couldn't do more than around a couple of megabytes per second

00:04:42.080 --> 00:04:47.840
at most at highp speeds it becomes difficult to keep the multiple data

00:04:46.160 --> 00:04:51.320
streams of a parallel connection synchronized which was part of the

00:04:49.560 --> 00:04:57.280
reason that the parallel port also became displaced by USB a much faster

00:04:54.680 --> 00:05:01.280
serial connection however both parallel and serial ports are still in use in

00:04:59.639 --> 00:05:06.240
some industrial and scientific applications as they provide simple

00:05:03.240 --> 00:05:08.479
interfaces that just work with older

00:05:06.240 --> 00:05:13.160
equipment finally we'd like to say a few words about the game Port somewhere

00:05:10.680 --> 00:05:17.840
between the parallel and serial ports in physical size this was a common way to

00:05:15.759 --> 00:05:23.680
connect joysticks and game paddles in the 1980s and '90s in the mid 1980s game

00:05:21.479 --> 00:05:29.000
ports were often included on expansion cards that also contained other types of

00:05:26.280 --> 00:05:33.120
ports but during the 1990s game ports became very very popular as it was

00:05:30.800 --> 00:05:37.880
typical for them to be placed on sound cards and seeing as Gamers were a key

00:05:35.479 --> 00:05:42.479
market for better sound quality the game Port was a natural choice for a cool

00:05:40.000 --> 00:05:47.600
value ad does that mean those sound cards were technically

00:05:44.639 --> 00:05:51.880
dongles H however the game Port could only support a limited number of buttons

00:05:49.800 --> 00:05:55.840
without a specialized driver and on top of that it was an analog connection

00:05:54.000 --> 00:06:00.240
leaving joysticks vulnerable to electrical noise that could mess with

00:05:57.400 --> 00:06:04.360
your inputs USB's digital nature which allowed easier support for fancier

00:06:02.120 --> 00:06:08.759
controllers meant the game Port fell out of fashion quickly during the 2000s and

00:06:06.840 --> 00:06:12.919
Windows dropped native support for it starting with Vista you know cuz they

00:06:11.160 --> 00:06:17.720
had to make room for the important things did you use another gone but not

00:06:15.440 --> 00:06:21.639
forgotten Port before the days of USB comment down below and you might see

00:06:19.199 --> 00:06:25.440
