Keywords

💡Bit

A bit, short for binary digit, is the fundamental unit of information in computing and digital communications. It represents a logical state with one of two possible values, typically understood as 1 (on) or 0 (off). In the video, the concept of a bit is introduced as the basic building block of digital information, akin to a letter in the alphabet of computer science, and is used to explain how data is transmitted and represented in a digital system.

💡Byte

A byte is a unit of digital information that typically consists of eight bits. It is used to represent a character in the character set that computers use. In the script, a byte is described as a package of bits, which allows for 256 different combinations, enabling the representation of a wide range of characters, including letters, numbers, and symbols. This concept is central to the video's explanation of how data is organized and interpreted in digital systems.

💡Digital Computing

Digital computing refers to the use of digital electronics within computers to perform operations based on binary digits (bits). The video script emphasizes that computers work on digital electronics, which involves the transmission of data in the form of 1s and 0s through a wire, illustrating the core principle behind digital information processing.

💡Mega Bit

Mega bit, often abbreviated as Mbps, stands for one million bits per second and is a unit of measurement for data transfer rates. While the term is not explicitly defined in the script, it is mentioned in the context of internet connection speeds, indicating the importance of understanding bits when discussing technology-related speeds and capacities.

💡Terabyte

A terabyte is a unit of digital storage capacity, equivalent to one trillion bytes. Although not fully explained in the script, the term is used to highlight the large-scale measurements of data storage and transfer in technology, setting the stage for future discussions on different kinds of data measurement units.

💡Flashlight Analogy

The flashlight analogy in the script is used to illustrate the concept of binary states in digital communication. It demonstrates how information can be transmitted using only two states (on/off or 1/0), which is analogous to how bits function in digital systems. This simple example helps viewers grasp the basic principle of digital information representation.

💡Alphabet of Digital Computing

The term 'alphabet of digital computing' is used in the script to describe the binary nature of digital information, where the 'letters' are limited to two states: 1 and 0. This concept is crucial for understanding how complex data is broken down into simple binary codes that computers can process.

💡Character Set

A character set is a collection of characters used in computing to represent text. In the video, it is mentioned that with 8 bits (a byte), 256 different packages or characters can be formed, which constitutes a character set that allows for the representation of a wide array of symbols, including letters, numbers, and punctuation.

💡Binary Digits

Binary digits, or bits, are the smallest units of data in a computer system. The script explains that bits are the building blocks of all digital information, with each bit having a value of either 1 or 0, and that these binary digits are used to encode and transmit data.

💡Technicality

While the script mentions 'technicality' in the context of simplifying the explanation of digital electronics, the term generally refers to the detailed and often complex aspects of a subject. In the video, the creator chooses to avoid technical jargon to make the concept of bits and bytes more accessible to the audience.

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
