Why are these keys used for? [ Print Sc, Scroll Lock, Pause Break ]


so computers have been evolving at an astonishing rate since its invention. but there’s one essential part of your
computer that haven’t changed a lot, the keyboard layout. and the chances are are that you
still don’t know why all of these keys you have in your keyboard are used for. and
today I’ll be concentrating on these three for the sake of time. so do they
have any practical use or is it as useless as the calculus in real life.
hey guys vighnesh here from tech detour and today we re going to find that out [music] these days, most keyboards have the print screen and the system request key combined so what do these actually do
. okay when it comes to the print screen key, you can pretty much guess what it’s
used for. to take screenshots obviously. but the thing is nothing is going to happen
if you press it and you’ll probably end up using the snipping tool to take
screenshots anyway. So how do we use it? to take screenshot of your PC using this button
you will have to press the the windows and the Print Screen key and it will instantly capture
your PC screen and will be saved in the screenshot folder in pictures. Now we’ll
see why the system request key is used for. so this key is actually used for
invoking low-level operating system functions to invoke in you’ll have to
press the alt and the system request button but windows just ignores it and nothing
is going to happen if you did that in Windows so you won’t be having any use
with the system request key at all in your day to day usage
.you’d have used the scroll or key to light up these crazy lights at least
once but apart from turning these lights on, do
this key have any other use? actually this key was designed to be used in way
older text mode environments which didn’t have much screen real estate. So people
actually used this for scrolling through the whole screen content using the arrow
keys instead of navigating the text entry cursor. but this is 2017 now we
have access to scroll wheels and scroll bars. So most of the application simply
ignores the scroll lock toggle. so this button literally has no use and is
completely obsolete at the moment. this is another key in our keyboard which an
average consumer has no use of. the pause break key. it were used in DOS and still
works in command prompt today. So what exactly does it do. the pause key is made
to pause or stop text mode program output and to terminate DOS application.
the pause key can also pause many computers during the bios boot-up so that
you can peacefully read the messages that flashes in your screen during boot-up
nonetheless it’s definitely useless when it comes to day-to-day usage. so now that
you know why these keys are used for, you might wonder who use this. well the short
answer to this is except a few number of pros, nobody use these keys and we can
conclude that these keys are indeed as useless as the calculus in our day to day usage. and with that being the case, i’m breaking it up for now and I’ll talk
to you guys in the comment section below
