creating these classes requires equipment and service.

If you appreciate this education, please think about going to Eli the computer guy dot com and offering a one time or monthly recurring donation.

As you know, I am Eli the computer guy, and in today's class, I'm going to give you an overview of the track for programming and four coding.

So a lot of people out there nowadays, they hear programming.

They hear coding is the way to make money, which is absolutely 100% true.

But they're a little bit confused about what the field looks like when we're talking about coding.

What are we talking about and how do you get involved with it?

So that's what we're going to be talking about in today's class.

So the first thing that we need to talk about is the basic idea of what is coding.

Essentially, when we talk about coding and we talk about programming, those are words that can be flip flopped around.

So somebody who's doing coding is doing programming and someone was doing program, and he's doing coding in some instances, it might be a little bit more specialized in that.

But basically programming and coding whenever you're talking about this a coder or a programmer, more or less is synonymous s.

So the first thing that we need to talk about is basically, what are you doing when you're programming or when you were coding?

All you are doing when you're a programming when you're coding is you are telling a computer what to do, right?

So basically what you're doing is you're writing out instructions to tell a computer or what to dio in specific circumstances.

So if somebody clicks a button, you want an email to fire off or you want an A T v A C system to turn on or you want a document to be printed.

If somebody goes and opens up your particular piece of software, you want to tell the computer how that software should operate.

So a very simple application that you may create is something like a basic calculator, right?

Somebody types in numbers they type in an operator operator will be a positive ah, plus side negative sign divided by or multiply so you type in a number you know to you type in plus two, you hit equal, and then you want your little application to add those +22 numbers together and pop out for two plus two equals four right on.

And so that is where you're going to write out how you want that to function.

You may may think about a more complicated piece of software that you may write seconds a piece of invoicing software where the invoices offer actually looks a lot like that calculator that we just talked about.

So what you do is you put in the different items that you have in your inventory.

Eso, maybe a calculator cost $2 a pencil cost $1 a pad of paper cost $3.

So if somebody comes in the store and they purchased three calculators and two pencils and a couple of pads of paper, what can happen is basically you type into the computer or you select and the computer that these items are being purchased, and then this invoicing piece of software will then figure out what the quantity is.

Figure out what the price is in the system they create a total print everything out so the customer could see it on.

Then you can actually take money from the customer and say that the invoice has been paid for beyond that, when we start talking about Cody and programming, something that I get very interested in is you can start doing things where you can start manipulating systems within your environment.

So so, one of things I like to play with a lot nowadays is our Guido's right.

And so with these micro controllers, what you can do is you can add sensors.

He's microcontroller, so you can add temperature sensors, light sensors, motion sensors just about any sense, or you can think about.

You can add when he's microcontrollers on.

Then what you could do is you can write code for these micro controllers that say, When this sensor senses X, y or Z, then I want an output toe happen.

All right, so let's say one of the one of the projects that I do a lot for real.

I think you did not come as I use a lot of the temperature sensors basically little temperature demonstrations.

So basically what you can say is if the temperature gets above a Sergent degree.

So if the temperature, let's say, gets above 90 degrees Fahrenheit, turn on a red led Adel's you doing else?

Uh, so, basically, if it's under 90 degrees Fahrenheit, turn on a green led.

So basically, if the temperature is too high, the light is red.

If the temperature is too low, there is lower than being too high.

The light is green to tell you how the temperature is.

With code is you could actually fire off things in order to have things that his notification email sent.

If the temperature goes above 90 degrees Fahrenheit, turn on the red led and send an e mail to whoever the administrator is right.

So basically what you're doing is you're typing out all of these commands.

Basically, if this condition is true, do this else do something else.

And the cool part is is you can do a lot of interesting things with coding in ways that you previously couldn't so a lot of you out there maybe thinking, Hey, you know, I've been watching Eli the computer guy for a long time.

He's done some coding classes in the past, but he has not been a big program.

Has kind of been a bit a little poo poo on the programming thing.

If you've been watching my videos over the past 10 years, why why is he getting into programming now?

Why is he starting to talk more about Cody now when he didn't really talk a lot about in the past?

Well, one of things to to realize is in the technology field, everything evolves.

So I got into I t basically I t like M c s C type stuff about 20 years ago.

And so 20 years ago, what you had is you had the system's folks, right?

S C, the list, Lennox system administrators, and maybe the Cisco people.

And they were over here, and then you had the developers and they were over here.

So basically, if your systems person, if you're in M.

C s see something like that, you took whatever the developers gave you.

However, itwas whatever condition it was another quality awas.

And then you trying to implement it into the real world on the reality is basically there was a massive big wall between the developers and the the operations people.

Basically, I t So the help desk people, the desktop support people, the systems people, right?

Even if your company had developers, right?

The anti people had no idea who the hell those developers even war like.

It is really hard to explain 20 years ago how remarkable wall there was between the developers and the operations people.

Basically, the developers handed you a product.

And as an I t person, it's right to make the dampening work right.

Things have cake, and the way that we do Architecture now has changed.

So back in the old days, we had something that was called a client server architecture.

So you had servers and servers or things like exchange servers, Web servers.

Whatever else, basically is a computer that was dedicated to providing service is to client computers.

And then you had the quiet computers would have, let's say, a Windows NT server, and then you have a windows in T workstation, right?

And in that environment, the server had specialized software installed on it.

So you had a server that had an operating system that had specialized software installed on it.

It had all the configurations for how it was supposed to provide.

Service is to the client computers and then the client computers that they would have the operating system.

They would have their client software installed on it, and then they would have the configuration to connect to the servers.

So that's basically how things were before.

And so the developers, the programmers, the coders, and they would develop server software clients off, or whatever else they would pass it over the wall.
