💡 Understanding Bits and Bytes in Digital Communication
This paragraph introduces the fundamental concepts of 'bit' and 'byte' in the context of digital technology. The speaker uses a flashlight as a metaphor to explain binary communication, where information is transmitted through two states: on (1) and off (0). The paragraph delves into the basics of digital electronics, where data is transferred as a series of 1s and 0s. It further explains that a 'bit' is a single binary digit, and a 'byte' is a collection of 8 bits, which can represent 256 unique characters. The choice of 8 bits for a byte is justified by historical computer architecture and the capacity to form a diverse set of characters for communication.
🔢 The Significance of Bytes in Early Computing and Character Representation
The second paragraph builds upon the understanding of bits and bytes established in the first, discussing the historical reasons behind the adoption of 8-bit bytes in computing. It mentions that early computers performed calculations using 8-bit packages, which contributed to the standardization of the 8-bit byte. The summary highlights the byte's role in representing characters from a character set, emphasizing the ability to define 256 distinct characters, including letters, numbers, and symbols. The paragraph concludes with a teaser for future videos that will explore larger units of measurement like kilobits, megabits, terabytes, and petabytes, which are used to quantify data transfer and storage capacities in technology.

Transcripts
hey guys and welcome to this video
another video of the fast tech skills
series in this video we're going to talk
about the meaning of bit and but you
probably probably heard these words
before either it's your mega bit
internet connection or terabyte hard
drive these words are being used very
often when it comes to tech and in this
particular video I'm going to explain
them and basically talk about what what
do they mean and why we're using these
words to describe the speed let's start
by a very simple example let's say that
this flashlight is torch that we have
here we want to kind of send information
just by having this flashlight so we
only have two states so when we want to
send some sort of information we can say
we can only send to two states of
information we can either have it on or
have it off so these are the only states
that we can communicate using this
flashlight if we want to just send some
signals maybe in the night out in the
world but with this flashlight you only
have two state so the message that you
form it needs to kind of consist of
different letters of only two states if
you think about it we have the alphabet
and alphabet has so many letters in this
alphabet we only have two letters we
have on and off or we can say 1 or 0 so
basically this is the computer and the
information technologies alphabet we
only can communicate using 2 States so
of course when we put together the
letters we can make words so now let's
just take this example and apply it to a
cable that we have in the area of
digital computing computers work based
on digital electronics and digital
electronics is basically kind of
starting out with a very simple logic
you
only transfer to States through a wire
so it could be only 1 or 0 same as the
torch we're not going to get technical
here but imagine that when the
electricity runs through the wire we
have 1 and when it's not we have 0 of
course their thresholds and technicality
about that but we're not going to get
into it so in digital computing we can
only use 0 and 1 and 2 to transfer data
between different parts of a computer or
different computers on a network so the
bits that we are talking about here
basically refers to one letter in the
alphabet of digital computing which
consists of only 1 and 0 so one bit we
can think of it as one letter
it's either 1 or 0 that would be our bit
right now because we need to send so
many ones and zeros through a cable to
convey our message to transfer data then
we need a bigger a kind of package of
these letters to actually convey a
meaning so what we've done in computer
science we have designed a way that we
can package different bits together and
we call that a byte so a byte is
basically if you think of it is a 8
letter well kind of work so it would be
2 3 4 5 6 and let's say we add 2 more
here and this would be our byte so a
byte is basically 8 bits so when we
basically put 8 bits together we have
created the package of byte sum of some
of you might actually ask why 8 bit why
we've picked the number 8 well if you
think of the possibilities the different
possibilities the kind of the different
packages that we can form with having 1
and 0 in each of these places
we can calculate that number of
possibilities with two to the power of
eight if you've done any math before you
know that the possibility of this one
would be one or zero
this one would be one on zero so we have
two possibilities for each position and
that would be a two to the power of
eight that would be equal to 256
different packages that we can form so
these are 256 packages we can turn them
into characters so we have one character
set 256 characters we can have plus
minus alpha by letters numbers different
signs like greater or smaller we have
can have the percentage sign we have the
capacity of actually defining 256
different characters so we can use to
communicate another reason that number
eight is picked because they're fairly
the very early stage computers they used
to use 8-bit packages to do calculations
so we had 8-bit computers back in the
day and that's another reason why this
8-bit package became the stunt standard
for a bite so now you get the idea
Abid stands for a 1 or 0 and a byte
stands for 8 bits in a row leading to a
particular character in the character
set that computers use of course in the
future videos we're going to talk about
kilobits megabits maybe terabytes
petabytes these different kind of
measuring to talk about the amount of
information that you can transfer or
compute or basically deal with when it
comes to technology so that's it for
this video let me know what you think in
the comments below subscribe to this
channel so I get more motivation to make
more of these videos and like this video
as well thanks for watching and I'll see
you in the next one
