First, a quick message from Common Craft. 00:00:00

It's easy to think of computers as just machinery, buttons, screens, and parts that work together. 00:00:14
But the magic of computers comes from something that makes them unique to you. 00:00:20
This is computer software in plain English. 00:00:25
The problem with computers is that most of us don't speak their language. 00:00:30
We need a translator, something that can understand our needs and put the computer to work for 00:00:34
us. 00:00:39
The translator is called software, and it makes computers useful. 00:00:40
Look at it this way. 00:00:44
Like a typewriter, a computer without software is just a lifeless machine. 00:00:46
By adding software, the computer becomes more alive, easy to use, and built for you. 00:00:51
Most computers have two basic kinds, the operating system and software programs. 00:00:58
If you've ever used a computer, you've used an operating system. 00:01:03
From saving files to using a mouse or fixing problems, the operating system covers the 00:01:07
basics. 00:01:12
Operating systems come with all new computers and do a lot of the same things. 00:01:14
We've seen them called Windows, Mac, and Linux. 00:01:18
But the operating system is only part of what we need. 00:01:23
To make them personalized and more useful, we can add software programs. 00:01:26
For example, if you need to edit a photo, you can add a software program that is built 00:01:31
for that purpose. 00:01:35
If you need to design a house, you can add a software program that lets you see the house 00:01:37
from all sides. 00:01:41
By adding and removing software programs, you can make the computer fit with exactly 00:01:43
what you want to do. 00:01:48
And adding most software programs is easy. 00:01:49
You can get them from a computer store or download them from the internet. 00:01:52
No computer nerds required. 00:01:56
Once a program is on your computer, opening it is as easy as clicking an icon. 00:01:59
But what is a software program? 00:02:04
What's really happening when you open one? 00:02:06
Think about it this way. 00:02:09
Computers are really good at following instructions. 00:02:10
A software program is essentially a set of instructions that tells the computer exactly 00:02:13
what to do. 00:02:18
When you open a program, the computer goes to work, completing the instructions until 00:02:19
the program is ready for you to use. 00:02:23
The ability to add and remove software programs means that everyone's computer can be different 00:02:26
and unique to them. 00:02:31
So, to review, we've talked about operating systems that take care of the basics and software 00:02:33
programs that make computers personalized. 00:02:38
It's this combination that makes computers so useful. 00:02:41
But it's not limited to computers on your desk. 00:02:44
Consider your cell phone. 00:02:47
Just like a computer without software, it's a lifeless machine that doesn't speak our 00:02:49
language. 00:02:53
Thankfully, cell phones have software that bring them to life. 00:02:54
The same thing is true for many cameras, music players, and even our cars. 00:02:58
Every day, we rely on software to bring machines to life and make them personalized and useful. 00:03:03
The next time you use a computer or cell phone, think about software's role in translating 00:03:09
your needs into instructions that put the machine to work for you. 00:03:13
