Today in BTT01 we covered a lot of new things. First of all we have a Photoshop Unit test on Elements 1 and 5 on the Wednesday after the one coming up. We looked at using electronic organization devices such as the calendar on the Woodbine Wiki or Google Calendars. Mr.Case will actually be giving us a mark on these for Term 3. The internet was first developed by the military for communication purposes. The Americans were afraid of the Russians dropping an atom bomb, and one of the side-effects of that bomb is an electromagnetic-pulse. An electromagnetic pulse kills all electronic devices that are active by overloading them. Anyways, back then you had to go through multiple phone lines just to get through to the one person that you wanted to talk to. This provided a lot of inflexibility, so the internet was developed. The internet is much like a web in that it can find it's way through multiple paths to the person that you want to talk to. An FTP stands for File Transfer Protocol and HTTP stands for Hyper Text Transfer Protocol (a set of rules for transferring hypertext pages). Every time you use WWW. or HTTP://, you are using the Hyper Text Transfer Protocol. HTML also stands for Hyper Text Mark-up Language, which is a coded language that allows us to link to other pages simply by clicking on a series of words or letters. A server or browser acts like a translator and translates/turns this code into something that we can see and understand. If you go to View, and then Surce you can see the HTML coding. If you edit the HTML coding, you can actually edit what you see on your webpage. However you cannot change the website on the internet (it is stored somewhere else safely and we're unable to access the original file), but only on your own computer if you save it. All Webpage/Website creating programs using the HTMl coding language to create new pages; you can either view the HTML code or the changes that come from it. Sometimes it is better to see the code itself, simply because you can see where there is a glitch since you can not see what is wrong in the browser or "finished" version. HTML codes can only do things with text, therefore pictures, logos, and videos/animations are not inlcuded in the HTML coding. Instead, there is a link which tells the coding where to get that pciture, logo, video, or animation from: usually a secure website or server. Finally a tag is a small code that you input and HTML code is basically just a series of tags.
