Transcripts

in this video we'll try to address the

elephant in the room what is computer

programming we'll also try to understand

what programming might mean to you let's

begin

we are surrounded by computers today and

they don't just come as desktops and

laptops anymore your phone for instance

your car your smart watch smart bulb

dishwasher refrigerators televisions the

list is truly endless in a nutshell

computers are everywhere

but for all their science fiction

likeness and portrayal computers are

essentially machines that need to be

told what to do

the age-old term garbage in garbage out

that has been used in the computer world

for a while simply means that a computer

depends on you to do what it must do if

your instructions are flawed then the

computer can't do much with it so to

summarize a computer must be told what

to do and that is precisely what

computer programming is all about

computer programming is the process of

writing a set of instructions that tell

a computer how to process data and

produce results this statement is quite

academic and doesn't give away the

magnitude of impact that this process

has on our world today so what are we

talking about well something like add

three numbers and then divide the result

by three now that is a set of

instructions which will compute the

average of Any Given set of three

numbers

but just how do you write these

instructions how do you write a computer

program well your computer understands a

special kind of language known as

machine code which is what the processor

inside your computer understands this

language is made up of binary numbers

the word binary here refers to two

possible States zero or one this is also

the same as saying off or on or true or

false

this is because processors at their

atomic level are a network of billions

of transistors which act like switches

or Gates controlling the movement of

electrical signals which is what makes

it all work

binary numbers act like states to these

switches and combinations of such

numbers are used to create and express

data and operations however machine code

for all its speed is not something that

us mortal humans can read or work with

that's why we often use the term low

level language when we talk about

machine code because these are

instructions that sit and work at the

processor level to solve this Gap we

have a class of languages known as

high-level languages that are expressed

in a language that we humans can easily

understand you've probably heard of them

already languages such as Java python C

plus plus JavaScript Ruby rust and so on

but before we go anywhere near how these

languages work you must ask yourself

what does programming mean to you well

programming could be many things it

could be working with your spreadsheet

in Microsoft Excel sending an email

using Google Mail playing a game setting

a smart bulb to turn on automatically in

the evening or even using the GPS in

your car to navigate yourself to a

location

undoubtedly computer programming is a

huge topic and there's a lot to learn

and discover we hope our video has

piqued your interest while helping you

learn what programming is all about and

of course we hope you are now feeling

ready and excited to explore more here's

a great way to get started and learn and

Zone with our outcome based immersive

learning approach we are fundamentally

disrupting the way New Age Technology is

alert you'll get to learn practice

assess

gain insights on your learning and

personalize your Learning Journey on our
