00:00:08.040 --> 00:00:14.099
been there your computer won't respond to Mouse clicks the keyboard on your

00:00:11.940 --> 00:00:19.199
smartphone is stopped working or your game console suddenly gets stuck in

00:00:16.279 --> 00:00:24.539
perma's screenshot mode fortunately there's often an easy fix for these

00:00:21.960 --> 00:00:29.480
catastrophic crashes turn it off and then turn it back on again and then

00:00:26.039 --> 00:00:32.099
oftentimes the issue has mysteriously

00:00:29.480 --> 00:00:38.040
vanished like sleeping off a night of heavy drinking but why does rebooting or

00:00:35.820 --> 00:00:42.600
at least restarting a problematic program seemed to be some kind of

00:00:40.079 --> 00:00:48.480
magical cure-all for your technology well it comes down to the fact that most

00:00:45.840 --> 00:00:53.700
computer freezes happen because of some kind of mishap that your system can't

00:00:50.820 --> 00:00:57.780
recover from on its own think of it this way suppose you're on a road trip and

00:00:55.860 --> 00:01:03.300
you see that the road is blocked off ahead because a truck overturned and

00:01:00.180 --> 00:01:05.159
Spilled five tons of thumbtacks but that

00:01:03.300 --> 00:01:09.060
doesn't pose a problem for you since you can just take the nearest exit navigate

00:01:06.900 --> 00:01:13.740
a few back roads and then get back on the highway a short while later but then

00:01:11.580 --> 00:01:19.200
let's say later on you come across a collapsed Bridge that's the only way to

00:01:16.680 --> 00:01:23.939
access a river for hundreds of miles on either side unless you somehow figure

00:01:21.299 --> 00:01:28.439
out a way to Your Wagon and float it across without losing a hundred

00:01:26.100 --> 00:01:32.759
pounds of buffalo meat you don't have any choice but to turn back around the

00:01:30.720 --> 00:01:37.259
way you came and start Down A New Path computers work similarly when they

00:01:35.100 --> 00:01:42.360
encounter a problem if the issue is more minor your system might be smart enough

00:01:39.659 --> 00:01:46.700
to work around it on its own for example if you're using a wired Ethernet

00:01:44.460 --> 00:01:52.140
connection and your adapter starts to misbehave it can transition over to

00:01:49.500 --> 00:01:57.119
Wi-Fi no problem so that you can carry on computing kind of like the Thumbtack

00:01:54.299 --> 00:02:02.340
truck example but in more serious cases like the collapsed Bridge your computer

00:01:59.100 --> 00:02:05.340
simply can't find a way through or

00:02:02.340 --> 00:02:07.740
around once they occur and it has to

00:02:05.340 --> 00:02:13.080
start back at square one sometimes code is written in a way that

00:02:10.560 --> 00:02:18.120
whatever program you're running expects some resource it's using to be present

00:02:15.480 --> 00:02:23.160
and behave a certain way a good example of this is certain blue screens of death

00:02:20.340 --> 00:02:28.440
in Windows such as the infamous page fault in non-paged area which in

00:02:26.160 --> 00:02:34.500
layman's terms means that Windows was trying to access a piece of data in

00:02:30.840 --> 00:02:36.480
memory that simply wasn't there and the

00:02:34.500 --> 00:02:40.260
code doesn't know what to do next kind of like when you encounter a vaguely

00:02:38.280 --> 00:02:46.920
worded exam question on a topic you didn't study in this case rebooting

00:02:43.379 --> 00:02:48.599
forces the Windows code to reload from

00:02:46.920 --> 00:02:53.040
the very beginning getting your system functioning again but even if your

00:02:51.120 --> 00:02:57.720
computer isn't hopelessly stuck in a blue screen it may be running very

00:02:55.080 --> 00:03:02.220
sluggishly due to a temperamental individual program

00:02:59.519 --> 00:03:07.260
badly written code can be stymied when it encounters an unexpected problem like

00:03:04.680 --> 00:03:11.760
in the Windows example or certain conditions can cause it to run in what's

00:03:09.300 --> 00:03:16.080
called an infinite Loop like like a trick dictionary that keeps sending you

00:03:13.440 --> 00:03:21.659
back and forth between two words Loops can hog lots of CPU time on your

00:03:19.260 --> 00:03:26.459
computer since the program won't stop and they can also make it difficult to

00:03:24.180 --> 00:03:30.659
force quit the program meaning that a reboot can break the loop and get you

00:03:28.860 --> 00:03:35.040
running again so that you can angrily uninstall the offending application and

00:03:33.120 --> 00:03:41.400
even applications that are behaving more or less normally can open up background

00:03:37.860 --> 00:03:44.879
processes that can hog memory or CPU

00:03:41.400 --> 00:03:47.400
Cycles or be affected themselves by

00:03:44.879 --> 00:03:51.780
other malfunctioning programs so a reboot will kill those processes and

00:03:49.799 --> 00:03:56.580
when your system starts back up only what it normally loads will be present

00:03:54.060 --> 00:04:01.440
in memory and since errors that programs simply aren't smart enough to recover

00:03:58.620 --> 00:04:06.420
from are so common turning it off and turning it back on again has become one

00:04:04.080 --> 00:04:12.060
