"Source code itself is the actual text document that the programmer creates: they type it up, it's letters, numbers, and symbols.",
"If you give that to somebody and have them look at that document on their computer, that's not going to help them view their email, it's not going to be a browser, it's just a text document.",

"There are two main ways this is done: either by an interpreter or a compiler.",
"Every browser has an interpreter, and that's how javascript is processed.",

"Unlike an interpreter, the compiler does all of its work on the programmer's end.",
"They send out their package, their product, and it's already been compiled, it can already run on a machine.",

"Everyone has an opinion to which is better (interpreter or compiler), but really each has their pros and cons, and it goes on a case by case basis.",

"Now, let's focus on what open source means.",

"Routers are the things that connect different small area networks.",
"I want to give a metaphor for this: I'm a teacher and I work at a school.",
"Say I have a package that I need to get to someone who works in the district offices.",
"I don't know where she is, I don't know where her office is located, but I know her name.",
"I go to my secretary, like my first router, and I say \"Hey, I need to get this to so-and-so at the district office, can you please help me?\", and she'll say \"Sure, I don't know exactly where her office is either, but I know the next step, I can get it to the district\".",

"That's really all it takes.",
"Routers can be different sizes, different capacities, but what they do is know their own neighborhood, take the information, and pass it in the right direction.",
"Another thing we'll get into a little later is that the routers don't even have to have the full package of information.",
"If one comptuer is trying to send information to another, the data might get split up between different routers and that's okay.",
"The computers still know how to put the information back together correctly.",

"This is an example of what packets might look like, a visual representation of the electrical current that the computer can translate into 1's and 0's, which we all know is binary that can represent literally any digital data.",
"These little packets are sent across through routers, and if a file is too large for one packet, it can be broken up into frames (smaller little packets).",
"The frames don't have to take the same route to the end destination.",

"Most specifically, we'll talk about how computers interpret analog sound and turn it into a digital file.",
"An analog sound wave could look like anything, but for this example it's a wavy line.",
"The computer takes it and measures at lots of different points, turning them into numbers.",
"This is called sampling.",
"Later, the computer can take those numbers and turn them into sound again.",
"Let's also discuss data compression.",
"The benefit of compression is that it's a smaller file: it's easier to store, it's easier to send to someone else, and it just takes up less space.",
"One of the ways this is done in sound is that the sampling is taken less often.",
"Another way is that it takes the measurement from a median point instead of from 0, so the numbers recorded are smaller.",
"In images, it's done by measuring groups of pixels by 16 instead of individually.",
"The takeaway from this video is that you'll want to use digital files as they're a higher quality, and when you're looking at compression, you want to decide how far you are willing to go to ensure the user still has the best possible experience."

"The basics of computer security, and how to make sure you protect your information.",
"Let's cover computer security.",
"The first thing we're going to talk about is something called a dictionary attack which has to do with your passwords.",
"When creating your passwords, some sites require extremely specific and complicated passwords, which is actually a bit unnecessary.",
"The type of attacks they're trying to gaurd you from are dictionary attacks.",
"Dictionary attacks are programmed to try every word in the dictionary, or in its own database of common words and passwords, as the password for a large mass of usernames.",
"If your password is Kangaroo, they're probably going to break into your account.",
"Most passwords aren't this simple, but that doesn't matter.",
"They attack such a massive amount of accounts that they only need a few passwords that are relatively simple.",
"When creating a password, you want to use different cases, numbers, and symbols, but one of the most effective ways to create a good password is to throw some random letters in there (ex: kangarooSyCA67).",
"Also, stay away from sequential numbers.",
"Phishing, another thing to watch out for, is emails or webpages that mimic other valid sites to try and trick people into entering their personal information, though the site truly isn't connected to the site it's trying to mimic.",
"In general, two ways to safeguard from these attacks are checking the address in the browser and to open a new browser and go to the website that is claiming to contact you.",
"Let's also discuss encryption and HTTPS.",
"If you are at Starbucks trying to access your bank account, you have reason to be suspicious that someone could see and take your information.",
"You will want to look for a green HTTPS instead of HTTP at the beginning of the web address.",
"That means that the site you're sending your information to is encrypting your passwords and other information, scrambling up data according to a code that only they know.",
"In general, whenever you're showing private or sensitive information, check for HTTPS.",
"A few other general tips: don't share passwords between important accounts.",
"If a site you use gets hacked into, your password may be compromised regardless of its strength.",
"Also, don't download strange files.",
"If you don't recognise the file type like .pdf, .txt, .jpg, be wary.",
"Some of these files you download can be very powerful and even run your computer from the inside.",
"Lastly, keep your software updated, particularly software that interacts with the internet.",
"One way that information can be compromised is when 'bad guys' find holes and gaps in security of older versions of softwares.",
"Those bugs have been patched in newer versions, so if you keep everything updated, you'll avoid lots of problems.",
