Transcripts

wonderful now without further ado let's

jump right into our very first lesson

where we'll focus on computer hardware

and software and this is going to be

imperative to understand although basic

because it's going to lay the foundation

as we move through this course

so what exactly do we have in store for

today's lesson well first of all we'll

kick things off by understanding and

reviewing the technology roadmap thus

far also note that i've included

timestamps here in the event that you

would like to fast forward to certain

topics then we'll move on to hardware

and software it is imperative that we

understand the importance of hardware

and software especially the software

side of things given that this is a

coding and technology course a lot of

what we will be doing in future is going

to be based on software and then lastly

we'll wrap things up by having a look at

modern technologies currently available

in industry and this includes innovative

and disruptive technologies wonderful

now here is just a quick fun fact you

know that your phone carries way more

computing and processing power than the

computer that first sent astronauts to

the moon if you think about how far

we've come that is actually really

insane and here we go our very first

topic of the day the technology roadmap

so without further ado let's dive right

into it now who exactly was the first

ever computer programmer well her name

was ada loveless and she was actually a

brilliant mathematician as well as a

writer now while ada loveless was the

first computer programmer her work was

largely based on that of charles babbage

in 1857 who developed the first

programmable computer however hardware

and software back then is not as we know

it today and technology has come a long

way since the 19th century

even today the most inexpensive mobile

devices are way more powerful and way

smaller than the most capable computing

devices back then and these are devices

we carry around in our pockets every

single day add to this the birth of the

internet and we now have an

interconnected network making our

computing devices so much more powerful

and intelligent now fast forward to the

20th century and it's companies like

microsoft and apple that have currently

revolutionized the personal computer

market and of the organizations and are

the organizations dominating this market

these systems were versatile and could

perform both personal and organizational

tasks which only spurred the adoption of

the new technology these companies soon

became the tech giants as we know them

today

as a result of constant innovation

and it was not too long before other

industry tech giants soon joined the

arena by leveraging modern technology

now these industry tech giants are

companies that you are most likely

familiar with and this includes

companies such as google

facebook and uber google is the world's

leading search engine and has indexed

most of the internet facebook on the

other hand is the world's biggest social

media platform and currently owns

whatsapp as well as instagram two other

popular social media platforms and then

lastly uber is the world's biggest and

most popular e-hailing service and the

and what makes uber such

and what has made uber such a success is

that uber actually does not necessarily

own any vehicles they essentially just

link customers with drivers

and here is just another quick fun fact

you may be wondering about the first

time the turing test was ever passed

while that supposedly happened at the

university of redding back in 2014

eugene gerstmann a program that

simulated a 13 year old ukrainian boy

convinced a panel of judges into

believing that it was a real boy

during the course of a five minute

conversation and for those who are

wondering what the turing test is it is

essentially the capability of a program

to illustrate or demonstrate human level

intelligence

now let us actually move on to the

second core topic of today's lesson and

this includes computer hardware and

software now let's start off by having a

look at peripherals also commonly known

as computer hardware which consists of a

variety of devices and this includes

both input as well as output devices

even our mobile devices are considered

hardware just not as powerful or as

complex as that of a personal computer

especially when you consider high-end

machines both for gaming and bitcoin

mining these machines are a lot more

powerful in terms of the computing power

now just a second ago we did mention

that peripherals or computer hardware

consists of both input as well as output

devices so what are some examples of

input devices first of all we have

keyboards and keypads which is often

used for typing characters we also have

such things as a computer mouse

which is often used to navigate the user

interface of various software packages

we use this includes things like google

chrome microsoft word you name it

microphones is just another popular

example especially when used for tasks

such as podcasting and take it from me

it's a worthwhile investment if

podcasting is your thing and then lastly

cameras is just another example of an

input device cameras are also considered

an input device given that it captures

and processes images taken through the

lens excellent now let's move on to some

examples of output devices and this

includes things such as monitors or even

your smartphone screen and this makes

sense because it outputs a visual

information to the user we also have

printers which is pretty much

self-explanatory and then lastly we have

speakers that output some audio

now sometimes these devices can be both

input and output devices a camera for

example

allows you to capture images which is

considered an input and sends images to

a laptop or personal computer and this

is considered an output so therefore it

can kind of be both the best way to

distinguish between the two is to ask

yourself if you are inputting

information to a system or retrieving it

this information exists in various

formats and this includes text image

audio and even videos now let's turn our

attention to software and let's have a

look at system software first of all so

what exactly is system software well

system software is one kind of software

that makes up the entire architecture of

a system whether it's a laptop a smart

tv or a smart phone now system software

can be thought of as the underlining

software that powers the application and

productivity software so in essence your

system software would generally be your

operating systems and this could be

android and you name it okay there are a

ton of operating systems available to

users out there depending on what it is

that you want to achieve and the

environment that you would like to work

in now let's have a look at some

examples of system software now our

first example over here is just

microsoft windows os which stands for

operating system and you'll often find

these operating systems installed on

your laptop brand such as samsung asus

dell acer and so on next up we have mac

os which is exclusive to apple's product

such as the macbook or the macbook pro

and then lastly we mentioned before

android which is not necessarily

exclusive to just one device but

available on a ton of devices out there

android makes up a big portion of the

operating system installed on mobile

devices around the world well over 60

believe it or not

now what about application software well

application software is a lot more

common than system software and it's

also more widely available out there and

basically comes from a ton of developers

not just your microsoft's and your

googles okay now it is often developed

by companies and developers to achieve

some sort of process or task for example

apps hosted on google's play store and

even apple's app store are considered

application softwares now you can think

of these as your day-to-day applications

that don't necessarily contribute

directly to your day-to-day productivity

or workflow excellent now let's take a

look at some examples of familiar

application softwares out there now once

again these examples might look quite

familiar to you and here's a couple of

examples of application software so uber

is definitely one this is one we

mentioned earlier google chrome is just

another example of application software

and then google music play which is now

discontinued unfortunately because this

used to be my favorite music player

application software out there one thing

you'll realize is that they don't

necessarily contribute to your

productivity so what about productivity

software then and how is it different

from application software well when it

comes to productivity software it's

pretty similar to that of application

software in fact it's still considered

an application if anything productivity

software is actually a subset or type of

application software this type of

software is generally used to improve

productivity and workflow of individuals

within an organization or even used to

automate manual tasks so we tend to

categorize these kinds of software much

like we do with other software such as

games or even ebooks i'm sure you are

quite familiar with this especially on

google's play so for example let's have

a look at some useful productivity

software tools that you could use as a

software developer

now in my opinion these are some

examples of some of the best software

tools out there that you can actually

use to enhance your workflow as a

software engineer or software developer

so let's take a look first we have just

in mind and just in mind is essentially

a mobile application or even a web

application prototyping tool one of the

most powerful features in just in mind

is that you can actually design logic

variables data lists masterless as if

the application works on a real device

and this is really really powerful in

the event that you actually want to sell

your product or idea or even bring a

concept to life now in module two of

this course i am going to introduce you

to just in mind where we will be working

on a e-commerce mobile application so

i'm really looking forward to that and i

do encourage you to stick around and

check those lessons out next we have

trello trado is extremely popular among

software development organizations that

manage projects now trello allows you to

manage the deliverables of any it

project for example that you might be

working on so you might have someone

working in ux or ui you might have

another team working on the database or

the back end telu allows you to manage

all of these deliverables until you

reach the end product

next up we have atom and atom is

basically a code editor for web

applications atom is quite popular

believe it or not and it's very close in

terms of its features to visual studio

or microsoft visual studio now in our

last two modules when we get to

scripting and coding atom is going to be

our preferred ide as a productivity tool

to write code

now speaking of software development i

believe this is an excellent time to

discuss coding so what exactly is coding

we've heard this buzzword over the last

several years

well coding refers to the ability of a

programmer to develop software for a

designated platform this includes

android or mac os for example think

about it like this humans don't speak

binary we have a hard enough time making

sense of all the ones and the zeros

conversely a computer can't understand

human language either so in order for

you to instruct the computer to perform

a specific task you need to design code

that can be interpreted by the computer

as an intermediary this is the purpose

of code coding is a form of writing

instructions that isn't binary to humans

that is much easier to learn and

interpret by humans yet a language that

the computer can still understand in

most cases when writing programs or code

you will likely be writing code that is

high level and one step removed from the

binary code this often means that you

will write code in an ide or an

integrated development environment which

acts as an interpreter for the computer

to understand the language it's as if

you are speaking to someone who does not

understand native english instead they

only understand their native language so

in order to effectively communicate with

that individual you will often require

an interpreter

now when it comes to coding we'll often

hear these two terms being used

interchangeably programmer as well as

software developers there are subtle

differences and there are big

differences and there are similarities

between the two let's have a look at the

list of the similarities and differences

now programmers are very capable of

writing code they are pretty much like

engineers and know how to build certain

systems or even design certain systems

they're also excellent in translating

requirements into code first of all what

are requirements requirements are

essentially the end goal when designing

a system a typical example of

requirement is when a button is clicked

some sort of event needs to happen now

programmers like i said before because

they have this engineer mentality they

are excellent at translating these

requirements into the actual build

now programmers are also highly capable

in a few languages and this is because

they are very focused you often find

that a programmer might be good in java

and c sharp or c

or java and dart and so on now the

reason for this is because when it comes

to object-oriented programming languages

especially your high-level languages

there are quite a few similarities

across these languages things like

classes inheritance and polymorphism

therefore programmers refine the focus

on just a couple of languages and they

master these languages now programmers

are also more of a technician role when

we say technician we can also refer to

the term engineers and the reason we say

they follow more of the technician or

engineering role is because they are

highly competent when it comes to the

technical aspects of programming and

then lastly computer programs are also

responsible for writing testing and

maintaining the source code now keep in

mind the source code is everything that

the programmer develops or writes from

scratch this individual will always have

to make sure that when writing the code

that they are following the right syntax

best practice and so on they must also

make sure that they are constantly

testing the code to make sure that all

standards are being met and then lastly

they have to maintain their source code

in the event that certain parts need to

be updated

now let's turn our attention to software

developers much like programmers

software developers are also very

capable of writing code regardless of

the language now software developers are

very good at translating high level

requirements and i think this is one

thing that really sets them apart from

programmers high level requirements here

refers to understanding the bigger

picture of why a system is being

developed and built not just

understanding the code but understanding

the processes involved in writing that

code and what the end product and what

the end process needs to achieve after

designing a system now software

developers are also very capable of

multiple languages and stacks software

developers are not necessarily defined

to understand one specific language they

need to understand a broad range of

languages this includes front end and

back in languages typical example would

be a full stack web developer who needs

to understand the ui aspect and the ux

aspect not just that they need to

understand the languages html css and

javascript for example would be your

front-end stack whereas with the back

end they need to understand things like

sql databases and php software

developers also tend to have more of a

creative and conceptual understanding of

everything so they are not just

technicians you can think as a software

developer as mentors to programmers and

therefore they are more of a

professional role now what do you mean

by professional rollover remember as a

professional in this industry in the

software development space you need to

be able to string together multiple

stacks therefore you're not just an

engineer and you are not just

technically inclined but you also

understand the business value of why

things are being done

and then lastly software developers are

good at analytics system architecture

and i.t project management roles and

this just goes back to the previous

point that was made earlier these roles

tend to be more of a professional role

as opposed to just technical roles such

as engineering or technician excellent

now for the final topic in this lesson

we are going to be focusing on modern

technologies such as ai the 4i art and

all of these new terms that have

recently come into play as innovative

technology has really grown over the

last couple of years

now most of us have heard of the second

and third industrial revolution in which

electrical power as well as information

technology were crucial building blocks

in society and this enabled us to

advance technology the fourth industrial

revolution however is an area in which

rapid advancements in technology through

innovations have brought us closer to

the digital world and this includes

things such as automation as well as

smart systems now this is often called

disruptive technology it's an area in

which society has become even more

invested in the use of technology to

drive various processes to achieve

specific tasks

and this brings us to the digital

society so the digital society is here

and it's time to adapt we refer to the

digital society or digital natives as

individuals who have adopted modern and

advanced technology as a daily part of

their lives through this term called

technology diffusion

these technologies have become

integrated with society to the extent

that we rely on them to perform simple

daily tasks such as maintaining our

calendar or even some of the more

complex tasks which include using it at

an organizational level to track sales

and social media engagement

digital natives are key to the adoption

of disruptive technologies and they

often require a specific skills and the

know-how to make use of these

technologies excellent so what exactly

are some of the characteristics of the

digital society first of all they are

key drivers in technology diffusion a

technology diffusion basically refers to

the rate at which technology is adopted

within a specific geographical location

or even around the world secondly they

are heavily invested in the use of

disruptive technology digital natives

are often the ones that either design

these technologies or they adopt these

technologies as early adopters they also

focus on technology integration

especially within an organizational

level and then lastly one of the key

characteristics of the digital society

is that they invest themselves in

adopting digital skills now this could

be something like being computer

literate or even learning how to write

software from scratch as an engineer or

a developer now many of us have heard of

artificial intelligence whether it's

good or bad now one of the most

promising technologies in the fourth

industrial revolution is the growing

interest in artificial intelligence

otherwise known as ai

artificial intelligence allows us to

perform predictive modeling forecasting

and even automation of mundane tasks

much like human intelligence artificial

intelligence allows for machines to

learn and identify trends based on a

given set of data which allows for

machines to take actions that maximize

its probability to achieve a specific

goal later in this module we'll actually

cover ai in detail in one of our lessons

wonderful now let's actually take a look

at some of the uses for artificial

intelligence now first of all we can

perform things such as predictive

modeling now what exactly is predictive

modeling it is the process of

implementing and using data as well as

statistics to make predictions of

outcomes with data models

data models can be used to make

predictions of just about anything from

customer behavior understanding stock

markets and even to predict an

organization's expected earnings over a

given period of time this could be years

months weeks

predictive modeling is also known as

predictive analytics and the two terms

are often used interchangeably

wonderful now let's move on to

forecasting forecasting allows

organizations to make predictions about

the future based on past events pretty

similar to predictive modeling or

predictive analytics there are three

types of forecasting or techniques first

there is qualitative a technique that

uses human judgment when hard factual

data is scarce and this includes data

such as numbers and this usually

involves the use of knowledge systems

you can also perform time series

analysis and projection which identifies

trends and patterns based entirely on

historical data and then lastly we can

also perform casual modeling a technique

used to identify a cause and effect

relationship between two or more

variables to make predictions

now as a last point of interest in terms

of usage of ai we can also perform

things such as automation ai is quite

popular in the domain of automation a

process in which little or no human

intervention is involved in carrying out

a particular task take your smartphone

for example not too long ago you would

have to manually enter a pin or password

to actually unlock your device these

days you can unlock your device simply

by looking at your selfie camera which

uses facial recognition software now

just another exhilarating and

interesting topic that we'll cover in

this module is immersive technologies

immersive technologies include those

technologies that are able to simulate a

real-world environment and increase our

suspension of disbelief making us feel

as if though we were actually present in

the virtual world

the technology has gained massive

traction in the virtual reality as well

as augmented reality space with major

technology giants such as oculus htc

vive microsoft and even facebook backing

its immense growth the oculus quiz 2 for

example has been coined one of the most

popular virtual reality headsets

available today

so what are some of the types of

immersive technologies available today

well first of all there's virtual

reality and virtual reality also known

as vr is essentially removing the user

from his current real world his physical

space and placing the user in a 3d

generated world or even a

computer-generated world the idea is

that you completely shut the user out

from the real world and give them access

to this virtual world where they can do

things such as perform training they can

interact with 3d objects or even the

physics within that environment games

are quite popular when it comes to

virtual reality but it's not the only

interest that has gone into virtual

reality teaching and learning for

example has seen a massive adoption in

this space we also have augmented

reality known as ar augmented reality is

different from virtual reality in that

the user is not removed from the

physical world or the real world instead

what happens is that the device actually

superimposes data over the real world

now a typical example here is

microsoft's hololens which is a set of

goggles and allows the user to still

have access to the real world while

overlaying a digital layer of

information and this could be things

such as text messages ui directions all

of those kind of things and then lastly

we have mixed reality mixed reality is

fairly new and involves a blend of both

virtual reality as well as augmented

reality we also have xr known as

extended reality and the idea behind x

auto extended reality is that it is an

umbrella term to encompass all of these

technologies excellent now this is

definitely worth mentioning as part of

your course material you will have

summary notes available to you with

every lesson that we cover in this

course now i believe this is an

excellent opportunity to review our

skills progression and also get an

overview of what to expect throughout

the remainder of the course

now we'll focus largely on the

fundamentals of technology in module one

so this is going to be very theory heavy

we'll discuss things like the principles

of technology we'll also learn more

about hardware and software even though

we've just touched on the very basics in

this lesson we'll then move on to

databases in one of our lessons in this

module and we'll have a practical here

just to demonstrate how we can actually

work with relational databases

next we'll move on to technology trends

in organizations and we'll have a look

at innovative technologies in greater

detail we'll then move on to usage in

industry from a project management

perspective even though in this lesson

we briefly covered some of the usage of

innovative technologies currently being

used out there

now we've also had a look at the fourth

industrial revolution but again we've

done so very briefly as we progress

through module one especially we're

going to go in depth on some of the

topics we touched on before our next big

core topic for this course is it project

management and again this is going to be

a big focus in module two the idea here

is to study it project management as a

whole to identify several useful tools

for it project management and then the

software development lifecycle which is

core in any it project management

setting

then we'll move on to tools in software

development we will have a look at

programming languages this includes both

for the web for gaming engines and even

for mobile applications we'll then have

a look at some useful frameworks that

you might want to consider as part of

your software development process and

then we'll move on to prototyping

prototyping is going to be really

exciting as mentioned before in

prototyping i'm actually going to

introduce you to just in mind and we'll

spend a couple of lessons designing a

working prototype of an e-commerce

application and then lastly we'll focus

on front-end web development in our last

two modules of this course you will

focus on things like the introduction to

web development with a bit of fury and

then once we've covered all the theory

we'll move on to html css and javascript

now this is going to be hands-on you

will be coding from scratch and i hope

all of you are looking forward to this

part because it's going to be exciting

and then lastly we'll wrap things up by

developing our functional website at the

end of this course you will also spend a

couple of lessons and will bring

together everything we've learned in

html css and javascript as a final

project and that brings us to the end of

our very first listening coding and

technology output was a really exciting

one for all of you as it was for me i

really look forward to seeing you in our

next lesson listen to we will focus on

ubiquitous technology this includes both

mobile and web so for all of that and

more

i'll see you in the next lesson

cheers
