GOOGLE & STUMBLE

Google and Stumble are alike because they both give you resutls for something that you are searchign for. They are different becuase Google tends to focus on only one topic that you request. On the contrary, with Stumble, you can search various topics at the same time. However, with stumble, you never know where it is going to take you. Google is more for specific searches ans Tumble is more for fun and just to look for stuff where you normally would not expect to.

SHOULD YOU BELIEVE EVERYTHING YOU SEE ON THE INTERNET?

You should not believe everything you see on the internet for obvious reasons. In some cases, anybody has access to these web sites and can alter the information in them. As a result, you get the wrong information. Wikipedia is one of the most unreliable sources because it is open to anyone who wants to edit it. You can probably determine which information is false by the source you are getting it from. For the best results, get information from .edu websites. When it comes to images, people can acuatlly photoshop images to make them look a certain way.

COMPUTERS = MAGIC ??????

I do not think that what computers do is magic. I think that the things it does are all predetermined settings which are applied when the device is created. For instance, when you input 2+2 in a calculator, it does not "magically" come up with the answer. On the contrary, it has already been set to output 4 when 2+2 is the input. Computers only understand on and off. As it turns out,  a computer is a very complex and dumb machine.
SOFTWARE: written by people
BINARY CODES: 1 and 0
INPUT: In code form you developed (DATA)
  • VIDEO CARDS
  • AUDIO CARDS

EMBEDED DEVICES

Some embeded devices that I rely on a daily basis include my alarm clock, my iPOD, cell phone and calculator. All of these devices are programmable or are already programed. Whatever the case may be, they are all an essential part of my daily life. For instance, I can program my alarm to wake me up at a certain time and play certain music.
