مقدمة في علم الحاسوب مع كاري آنا فيلبن

[Music] Hello world. I'm Carianne Philin and welcome to Crash Course Computer

Science. So computers really have allowed us to do some pretty amazing things. Think global telecommunications,

international commerce, global transportation, breakthroughs in medicine, distributed education, online

shopping, online dating, and just the internet in general. Computers are allowing us to

explore our own world and other worlds. And of course, some seemingly mundane things like permitting us to spy on our

pets from work or communicating with our friends in a nearly indecipherable stream of emoji. But don't call

computers magical. They are not, I repeat, are not magical. So, before we get into what we're going to talk about

in this series, it might be useful to tell you what we are not going to talk about. We aren't going to teach you how

to program. Programming is a really crucial aspect of computer science and we will get to the rules that guide the

logic of hardware and software design. But we aren't going to teach you how to program an Arduino to water your plant

or how to change the CSS on your grandma's sewing blog so visitors cursors turn into kittens. This also

isn't a computing course or at least how computing is thought of in the US. Computing here is a goal. It's what

computers do and we'll talk about some of that for sure, but our goal for this course is much broader. But computing

means other things in other countries. It's all pretty confusing, but what we are going to look at are the history of

computers even before we had electricity. We're going to retrace the design decisions that have given us our

present- day components. We're going to talk about how operating systems work or don't work, how the YouTubes get to over

the internet, how our smartphones and other smart devices are well getting smarter, and of course, mysterious

futuristic stuff like quantum computing and frustrating present-day stuff like hacking. It's a lot to cover, but I

suppose before we get started, I should introduce myself. I'm Kerianne Philin. Hello. I'm an award-winning computing

teacher, author of Adventures in Raspberry Pi, and the creator of a YouTube video series for teenagers

called The Geek Girl Diaries, which includes stuff like interviews with women working in technology, computer

science-based tutorials, and hands-on digital maker style projects. In my day job, I help people learn about

technology and how to make things with computers as director of education for the Raspberry Pi Foundation, which is a

charity based in Cambridge in the UK. Needless to say, I am passionate about this stuff, but not because computers

are these amazing devices that are always making our lives easier. Sometimes that's debatable, but because

computers inarguably have become pivotal in our society. From our cars and thermostats to pacemakers and cell

phones, computers are everywhere. And it's my hope that by the end of this course, you'll have a better

understanding and appreciation for how far we've come and how far they may take us. I'll see you next week.
