00:00:00.240 --> 00:00:08.160
one of the nice things about modern Computing is the move towards one port

00:00:05.480 --> 00:00:14.240
for seemingly everything and yes I know that audio

00:00:11.639 --> 00:00:18.720
monitors and Ethernet are major exceptions but since the introduction of

00:00:17.359 --> 00:00:24.800
USB in 1996 we have come a long way from the

00:00:21.960 --> 00:00:31.679
days when it seemed like every single device had its own specialized Port but

00:00:28.480 --> 00:00:34.600
even so there's one crucial situation

00:00:31.679 --> 00:00:41.680
where some folks still haven't fully embraced USB I'm talking keyboards and

00:00:38.640 --> 00:00:45.680
mice while the vast majority of these

00:00:41.680 --> 00:00:47.840
input devices sold do connect via USB

00:00:45.680 --> 00:00:53.000
there's actually still a different connection that some people still use

00:00:50.160 --> 00:01:00.600
the venerable PS2 Port so why do some people still prefer

00:00:56.879 --> 00:01:04.320
these round green and purple 90

00:01:00.600 --> 00:01:08.159
Throwbacks well although both PS2 and

00:01:04.320 --> 00:01:10.960
USB seem to do the same thing connect a

00:01:08.159 --> 00:01:16.159
keyboard or Mouse to your computer there are a number of significant differences

00:01:13.560 --> 00:01:22.439
in how they work that make them still seem relevant even on high-end

00:01:18.479 --> 00:01:26.000
motherboards you see a USB keyboard or

00:01:22.439 --> 00:01:29.920
Mouse connection works by pulling your

00:01:26.000 --> 00:01:33.520
device so in the computer equivalent of

00:01:29.920 --> 00:01:35.240
Are We There Yet many times per second

00:01:33.520 --> 00:01:40.000
your computer essentially asks your keyboard or Mouse hey what you doing

00:01:37.520 --> 00:01:45.200
what you doing what you doing and the keyboard or Mouse will then respond by

00:01:42.000 --> 00:01:48.439
saying for example nothing moving to the

00:01:45.200 --> 00:01:51.240
left having my D key pushed down or

00:01:48.439 --> 00:01:54.719
strangling my owner PS2 devices on the other

00:01:54.719 --> 00:02:02.600
hand work by sending interrupts to the

00:01:58.840 --> 00:02:05.200
system so instead of waiting around for

00:02:02.600 --> 00:02:11.480
the computer to ask about its current state the PS2 protocol allows your

00:02:07.880 --> 00:02:14.040
keyboard or Mouse to actively interrupt

00:02:11.480 --> 00:02:20.000
whatever your CPU is doing to tell the computer what's happening and this might

00:02:17.200 --> 00:02:25.680
sound potentially inefficient but because modern CPUs run at millions or

00:02:22.640 --> 00:02:28.360
even billions of cycles per second you'd

00:02:25.680 --> 00:02:35.720
never notice a Slowdown so it's for this reason that some enthus iasts claim that

00:02:31.640 --> 00:02:38.120
PS2 has less perceptible latency which

00:02:35.720 --> 00:02:44.720
should theoretically make response times quicker in games and PS2 also supports

00:02:42.360 --> 00:02:50.640
true en key rollover meaning that the system will register as many keys as you

00:02:47.239 --> 00:02:52.720
can push down at once there are USB

00:02:50.640 --> 00:02:58.319
keyboards that also advertise this functionality but this is usually done

00:02:55.400 --> 00:03:02.640
by emulating multiple keyboards which can limit how many additional input

00:03:00.280 --> 00:03:08.920
devices you can connect by requiring special software or by suffering from

00:03:05.840 --> 00:03:11.879
compatibility issues at boot time

00:03:08.920 --> 00:03:17.799
because PS2 is a dedicated interface just for keyboards and mice PS2 devices

00:03:15.319 --> 00:03:22.239
don't have weird issues where your computer doesn't recognize them properly

00:03:19.799 --> 00:03:25.920
in the BIOS or before Windows loads drivers as can happen occasionally with

00:03:24.519 --> 00:03:33.239
USB gadgets wow well that's a lot of

00:03:29.040 --> 00:03:37.040
benefits Long Live PS2 right well hold

00:03:33.239 --> 00:03:39.720
on in reality the virtually certain to

00:03:37.040 --> 00:03:45.200
work level of compatibility is about its only real world benefit for most people

00:03:42.400 --> 00:03:50.080
even many competitive Gamers have apped that whatever enhanced responsiveness

00:03:47.360 --> 00:03:54.360
they get from PS2 is basically imperceptible with factors like key

00:03:52.280 --> 00:04:00.959
switch type being much more important for a Competitive Edge and PS2 has other

00:03:58.000 --> 00:04:06.840
limitations as well it wasn't designed to be electrically hot swappable and on

00:04:04.319 --> 00:04:12.400
older Hardware trying to swap out a keyboard or Mouse can make it not work

00:04:09.319 --> 00:04:15.480
until you reboot or even worse actually

00:04:12.400 --> 00:04:17.560
damage your equipment and not only that

00:04:15.480 --> 00:04:22.520
since they weren't meant to be unplugged and plugged back in frequently it is

00:04:19.759 --> 00:04:28.040
easy to bend or even break the little pins at the end of the cable so in short

00:04:25.280 --> 00:04:33.360
PS2 connectors take up more space and simply aren't as tough

00:04:30.360 --> 00:04:37.000
as their USB counterparts so unless you

00:04:33.360 --> 00:04:39.400
have a very specific need for PS2 it

00:04:37.000 --> 00:04:45.240
technicians still love them there's really no reason to fear missing out on

00:04:43.199 --> 00:04:49.280
anything if you just go with a USB keyboard assuming of course that you

00:04:47.000 --> 00:04:56.160
don't have a classic Model m keyboard that uses it or you know maybe just a a

00:04:52.560 --> 00:04:59.199
major old school IO fetish for like

00:04:56.160 --> 00:05:03.520
those giant printer ports that we all

00:04:59.199 --> 00:05:05.520
know and tolerate tunnel bear VPN lets

00:05:03.520 --> 00:05:09.080
you tunnel to 20 different countries allowing you to browse the internet and

00:05:07.280 --> 00:05:16.320
use online services as though you're in a different country but Lon is vpns are

00:05:12.199 --> 00:05:18.560
hard to use port configurations and blah

00:05:16.320 --> 00:05:23.759
blah no it's actually super simple tunnel Bears available for iOS Android

00:05:21.479 --> 00:05:28.759
PC and Mac they even have a Chrome extension and you basically just press

00:05:26.560 --> 00:05:33.120
one button and when you press the button a couple things happen your connection

00:05:30.520 --> 00:05:37.680
gets encrypted with AES 256-bit encryption which makes it harder for

00:05:35.160 --> 00:05:42.400
your ISP to track what you're doing online and your public IP address gets

00:05:40.639 --> 00:05:48.400
switched so you show up as though you're in a different country allowing you to

00:05:44.600 --> 00:05:50.240
bypass pesky Geo restrictions that limit

00:05:48.400 --> 00:05:54.800
the video content that you can watch or the news articles that you can read for

00:05:52.440 --> 00:05:59.919
