Energy Star Program
I never knew there was a program that exists that helped to reduce the amount of electricity used by computers and other electronic devices I never knew there was Green Computing usages techniques. But now I know some suggestions I can use to use Green computing. For example at night I am going to shut my computer system down instead of leaving it on and instead of throwing away old printer cartridges I will recycle them. You have to start some where.
Encryption
I never heard of encryption until reading the book. It sounds like a good simple security system. I wish there was a little more information about it in the book. But it is interesting how the data has to be decrypted from cipher text into plain text so that we are able to read the messages.
Root kits
Rootkits are pretty interesting but scary. Somone can just get on the computer and control what happens with it, but what happens once they do get in control of it. I know that viruses and spams are bad but I have never heard of a root kit.

TOP 3 Big Darn Deals for Chapter 8
1. Coaxial cable
I never knew the name of the cable that was used for the computer and t.v. Now I know the name is coaxial cable. The information form the book taught me what a coax is made of and why it's better than a twisted pair cable.
2. Twisted pair cable
I have never heard of a twisted pair cable. I didn't know that it produced noise either. I've heard of line noise and line noise filters that reduce noise, but I didn't know this is also a cable or an installation that can reduce "noise." I also know now that a twisted pair cable is better than a coaxial cable so I am definitely going to keep that in mind.
3. ISP Internet Service Provider
Now that I started working as an ISP Customer Support technician I've started to learn more about ISP's and how restaurant's use it to maintain their store data, registers, and store information. Now that I completed chapter 8 and the activities that consisted with Chapter 8, I learned that ISP stands for Internet Service Provider. Which surprised me because I have never thought of it before!

Chapter 7 BIG DARN DEALS
3 BIG DARN DEALS FOR ME ARE:
- UNIX and LINUX
I never heard of the Unix operating system existed until I read chapter 7 and did the research assignment for chapter 7. I know that McDonalds uses a Unix, but I never knew it was an operating system. Learning about Linux was awesome too because I've never heard of it. I think its good for people to learn of other operating systems other than Windows. PLus its good that we learned this because Linux and Unix are used in businesses we might work for.
-BACKUP
I found it interesting that there is a way to get files that we lose. I wish I would have known that in highschool because I can't count the many times I had to rewrite a report that was more than 1 page because my computer shut down or something happend to it.
-DISK DEFRAGMENTER
I think this utilty is great! It's like a personal assistant for us to use on our computer. It helps organize and create more disk space.

3 BiG DaRn Deals on Chapter 6!
1. RFID Tags and Preschoolers
I was pretty concerned learning about the RFID tags and attaching them to preschoolers and passports. I think RFID is a good idea for certain things, like businesses and offices, but to keep an eye on kids. I think they just wanted to experiment on someone, but they knew that kids won't complain. It just seems weird to why they would want to attach RFID tags to kids while they are in school. The advisor for the preschool or head start program just didn't have any good points and it seemed kind of shady. Placing RFID technology on passports I think is a terrible idea also. I think it’s kind of like a form of discrimination.
2. Cloud Storage
I never realized that everyday when I check my mail that it’s a form of cloud storage. It does make sense, and I like the idea of cloud storage because you can be able to access that information even if you are in another location. The only thing I'm concerned about is who else gets to access it? The guy on the podcast did make a point that people sign up for things but when it comes to the agreement portion they just check I agree and continue on with the process, which is true. I also do that when I’m downloading things or signing up for things. But now it makes me wonder what is really in the agreement and who else gets to access the things I’m using.
3. Perpendicular Storage
I feel like the perpendicular storage is a good idea, but why wasn't it thought about earlier. Feels like it should have been done a while back ago. But it is helpful. I guess its kind of common sense that perpendicular makes more space than the elongated way.

Chapter 5 BIG DARN DEALS
Numero Uno:
First and foremost I have never seen any of those keyboards we had to view in those videos. They look cool but complicated. And I didn't really understand why someone would need a portable keyboard you can roll and put in your pocket. I mean if there is a computer where you’re going then there will be a keyboard, right? And I know there was another keyboard that was meant to be more comfortable but it looks more uncomfortable to me. Maybe it’s because I've used the same standard type of computer everywhere I've used a computer.
2: SMART CLOTHING
I know that technology is getting more and more knowledge everyday, but who would have thought they would have came up with clothes that can tell you you’re every movement or that can charge and iPod. Reading those articles scared me because now I’m just like what should I expect in the next 10 years from now?
3: Magnetic stripe ad input/output
I was surprised when I read that the magnetic stripe has information on it. That would explain a lot. After thinking about it, how would the machine in the store know that the pin I put in was incorrect or correct? That's amazing to me that a black strip has information on it and you can't even tell. What else has information that we don't know about is the question.

Top 3 BIG DARN DEALS Chapter 4
I thought I knew most of the basics about computers until I read Chapter 4.
1. First and foremost I never knew what RAM or ROM meant I knew it had something to do with memory but never knew that there was a difference between the two, being volatile and permanent. Now I know that RAM= Random Access Memory and is volatile meaning that it is not permanent. ROM=Read-Only Memory and is non-volatile which means PERMANENT.
2. I was always confused when it came to memory sizes, like KB, MB, GB, and TB. Now I know that KB is kilobytes, GB is Gigabytes, MB is megabytes, and TB is terabyte. I've heard of megabytes and gigabytes but not the other two. I also never knew which one was smaller and larger. But now I know that KB= 1 thousand, MB= 1 million, GB= billion, TB= 1 trillion. So KB is obviously the smallest out of all four and TB is the largest.
3. I think it was pretty cool doing the Motherboard lab because I've never seen the inside of a computer. I probably have once but didn't know what I was looking at. It still looked confusing when I seen it in the book and in the lab but at least now I can identify where things go on it and compare it to a residential piece of land with buses and tree poles like the lab referred it as.

The top 3 "big darn deals" on Chapter 2
After reading chapter 2, I realized that there are more web browsers out there than Internet Explorer. I have heard of and used Firefox and Netscape but for some reason I was really set on Internet Explorer being the main Web browser. I find that weird since there are other options! The second thing I learned in Chapter 2 is that IP addresses and the domain name both correlate. I didn't even know that they had anything in common. But now I know that the IP address is basically the number format and the domain name is the word format for the name of the website. The third thing I learned in Chapter 2 is about Netiquette. Last semester when I took my first computer class I heard my teacher refer to Internet Etiquette as Netiquette and I thought she was creative for just making it up right there on the spot. Now after reading chapter 2 it’s like "Netiquette" is a world wide thing! But it is pretty good to have the netiquette guide because most of the guidelines on it make sense and have a point.
