Crtira G and H--dog draft

G: Identifying the Problem within Social Context--

This year, the first senior class will be graduating and leaving Al-Arqam Islamic School and College Preparatory forever. This is their last year to set traditions, break school rules and receive a memento from the school. They thing it would be really nice to have a special and loving memento from the school that appreciates them and is also a sort of farewell gift. However, the school is too busy to have someone work on a gift for the seniors. They are working hard on the new IB school and curriculum as well as making the school better known within the state. One of the IT solutions help make the school more well-known within the community and helps outsiders see it as well.

H: Analysis and Feasibility Study--

Two possible IT Solutions are a Senior Slideshow or a Senior Sweater.

Senior Slideshow:

This slideshow consists of photographs of the senior class throughout their years in the school as well as their senior pictures.

4. Information is stored in some kind of binary format because it cant understand words. It has to be given a little bit by little bit.

5. You normally cant run Macintosh software on a PC with Intel Pentium 4 CPU because they have a different set since they are older computers. A PowerPC CPU cant decipher Intel Pelitium instructions and vice versa.

6.Another factor in determining a CPUS's processing speed is by

7. Its important that computers support both internal and external expansions because then you would be able to plug in a keyboard, a mouse and even the monitor itself. You can also put in cards called PC cards that have memory in them and you can save files onto it.

8. Symmetrical multiprocessing can increase a computers performance by giving it more room and memory, which makes them work faster. Some examples of symmetric multiprocessing is the Xbox 360 and the Play Station 3.

9. The difference between RAM and ROM is that the RAM contains information temporarily and can loose info where as ROM is the back-up to the RAM, and keeps information on it.

10. The difference between primaray and secondary storage is that the primary storage is the hard drive which is also used for the CPU. examples of hard drives: the RAM and ROM. Secondary storage is when you used flash drives, cd's, floppy disks, etc.

<-- My super tight drawing of computer

TechReflect 10/22

Imagine you were asleep for a thousand years and suddenly woke up in this technological age. What are some things that can help you get up-to-date with using technology?

If i was asleep for a thousand years and suddenly woke up in this technological age, some things that can help me to get up-to-date with using technology is reading the Dummied Guide to computers and then playing around/exploring the computer and what it has to offer. After figuring out the computer, you can figure out any tech thing. Cellphones, itouchs, ipods, etc.


b.) What inspired Alan Kay is that he wanted to invent the future and for the computers he wanted the children to be able to work with it. Alan Kay accomplishe many things. He invented the Dynabook which is pretty much like the Personal Computer. He also helped develop the Macintosh which is the firt computer to incorporate many of Kays far-reaching ideas. After 12 years of being a researcher at Apple, he left to Disney where he developed Squeak. In 2002 he joined Hewlett-Packards research lab while continuing work with Viewpoints Research Institute. In 2004 he was given an award.

TechReflect

Yes, i think that educational games are good ways for students to learn at school. For example, Oregan Trail!!! That game taught us how to haggle, critically think--pretty much survive!

b.) yes even this game! it helps you! its a lot of strategy!

3 podcasts

the podcasts i have been listening were similar in the way they were formated.
They started off with an energetic beat, gave announcements and then gave a breif description on what that days podcast was about. Then they would turn to the person they were interviewing (at least im assuming so) and would then start the show.

Review A

Explain how and why the Internet was created.

The internet was created by a group of scientists who wanted to share research with each other. But then they realized that this internet could be a new technology! Even though internet is government based, its not government run.

Describe the technology that’s at the heart of the Internet.

The technology thats at the heart of the Internet is the TCP/IP (transmission Control Protocol/Internet Protocol). it is supposed to be the language of the internet, allowing cross-network communication for almost every type of network and computer. The TCP breaks messages into packets. IP is the address for the packets where each four numbers is separated by a period. There is also the DNS (domain name system) that translates the IP numbers into names. Theres emailing where you have an email address.

Describe the technology that makes the Web work as a multimedia mass medium.

HTTP and HTML are the main tech that makes the web work as multimedia mass medium.

RSS stuff

How easy/difficult is it to use RSS?

RSS is not difficult to use. In fact it is rather simple and excruciatingly easy. It is when information or updates automatically come to you. Its technical definition is an XML-based format for sharing. Some sites that carries this is for instance, Facebook. On your homepage, you automatically get people updates on their profile: a new pic thats up, a change in their status, etc. This saves a lot of time from you going onto their page and finding these things out. Another website that has this is myspace. it is the same as facebook. you get updates from peoples pages.

A Boolean Logice is a way of searching with quotations. for example you would search on google, "hygiene AND 18th century AND NOT ENGLAND)

Review friday 10/2

What do email addresses and URLs have in common?

URLs and email addresses both carry the domain naming system. A web URL specifies the IP address of the Web server that houses the page. In an email, the domain name system is used to pinpoint the internet location of the host computer that contains the users email server. It includes user name and host address.

Review thursday 10/1

a) How does the type of Internet connection influence the things you can do on the internet?

It all depends on the kind of internet connection to do things on the internet because if its slow then you cant watch youtube clips or play games. Direct Connections is the best way to go because then you can take full advantage of internet service without the need to dial in. Plus, all of your files are stored on the comp and response time is much faster.

b) Choose 2 areas of impact to discuss 1-2 (in total 3) social & ethical issues related to internet connections.

Education-- Equality of Access: Students and teachers can search up educational information on the internet and will be allowed access to as much info as they want. - Control: Students and teachers have control over how much info they want and how much they dont want. - Reliability: Students and teachers feel comfortable and trust the internet connection to be able to use the internet and find information.

Health--Authenticity: A diseased human doesnt have to call up a hospital to ask about his disease but instead can go onto the hospitals website and see how they treat his kind of disease. - Integrity: However, though there are some accurate websites, some like Wikipedia, an ill human cannot always relie on it.

Review ?s

a) Why is it hard to determine how big the Internet is today? Give several reasons.

The internet is a network of networks. It carries a lot of national, statewide, and regional netwroks including hundreds of networks in colleges and research labs and thousands of commercial sites all over the planet. No one has the power to control the Nets operation or evolution. It, the internet, is considered to be a huge anarchy. Here are three main reasons why its impossible to determine how big the internet is:

• The internet is seriously growing waaay too fast! Millions of new users go on and create blogs, websites and profiles. And the other millions (or billions) of people who are on are adding new connections by the minute.


• There is no "Internet Central" to keep track of all of the people.


• The internet doesnt have hard boundaries.

b) Why are TCP/IP protocols so important to the functioning of the Internet? What do they do?

TCP/IP protocols are so important because internet seriously cannot function without them.

Mainframe and Microcomputer

The difference between a mainframe and microcomputer is that a mainframe is room-sized machines with price tags to match. Banks and airlines still use mainframes for big computing jobs. A Microcomputer is pretty much a PC--Personnel Computer. PCs is a computer which is designed to be used by one person at a time as a tool for enhancing productivity, creativity, or communication. They are in offices, factories, homes, schools, and pretty much everywhere else. They can be classified as desktop computers, workstations, or laptop computers. PCs have taken many tasks that were originally performed by larger computers. With the rise of PCs, users gained a lot more control over their computing environments.

TechReflect: major events b4 20th century

Major events before the twentieth century influenced the development of computers. In the early nineteenth century, computers were humans. They had made mathematical tables which, they found out, carried many mistakes. This is when a British pair, Charles Babbage and Augusta Ada King, the Countess of Lovelace, thought of a construction of mechanical computers that would automatically and reliably perform the tasks in which the mathematical table did. However, it took engineers 125 years to be able to make that thought into a reality.

Automobiles and the television are good examples of tech inventions that have seriously changed our lives. Some good things about automobiles is that they help you get to places faster, hence creating a faster way to run errands, go to school, buy groceries, visit people, etc. But just as their are good things, there are also bad things about automobiles. Automobiles make us humans forget how to walk a long time-span. We gain weight, become more lazy and we forget to appreciate the automobile, or "cars". Some positive things about television is that it helps you to see a different world, they tell stories, and also keep us updated on whats going on around the world. With television, we can watch educational films about space, earth and animals. It is our source of entertainment as well as education. However, there are also many negative things about television. The television carries profanity, bad morals and inappropriate scenes and/or images. This can cause children to say foul language, act improperly and being too mature while be so young--in a bad way. Even thought i watch TV and its something i watch almost regularly, I can definitely live without it. Because even thought there are some good things, the bad outweighs it so much more. Whereas the automobile, even though we become fat and lazy, it is still very important to have something that can take you somewhere far in a short time period and carry bags of groceries and or clothes.

The computer is very interesting. It is used for education as well as entertainment. You can watch educational bio clips on how to dissect something to researching on wikipedia on a scholar or bacteria for an essay. You can also watch movies, play games and do so much more! but there are also a lot of bad things about computers. It takes up too much time and it too contains inappropriate things for children. However, the computer is totally awesome and i cannot live without it!

Facebook article

http://www.cnn.com/2009/TECH/08/27/cnet.aclu.facebook.app/index.html?iref=newssearch


This article is about facebook quizzes and how once you take them, they carry all of your information, including pictures. So these people who care about privacy, etc. are trying to flag facebook and get them to update their privacy policies.

Techy Article

http://www.cnn.com/2009/TECH/08/26/wikipedia.editors/index.html

This article talks about how Wikipedia will now be trying a new thing where they will have "editorial control" over whats being said. Even though anyone is still aloud to add info or take it away, they will have to be approved first.

Feelings concerning Computers.

My feelings concerning computers are both positvie and negative. I love how i can just go on the internet and easily serch up on a scholar or find out who wrote what, etcetera. I dont have to do the old fashioned way by going to the library and finding books concerning scholars, authors, etcetera. All i have to do is go on Google and vola! all of the info is there! But here is where my negative feelings come in. Even though you get so much information from the computer, its not always correct! A lot of fake info is put up on the web these days, its sad. Also, even though i highly enjoy typing, typing can sometimes be such a pain. And a lot of times there is nothing to do on the computer after you have done all that you needed to do. butchyea. those are my pos and negative feelings bout such.

Education: Keeps schools safer.

>FIVE web Communities<

Here is a list of five web communities:
1. Facebook
2. Myspace
3. Naseeb
4. Hi5
5. Tag

All of these web communities are for people to get together and stay connected. Myspace and Facebook are both of a Intellectual Property. This is because, even though for both of them you can have profile pics, take quizzes, edit profiles, see other peoples profiles, etc, myspace is more private than facebook. In facebook you can see other peoples conversations come up on you wall, while as in myspace, you just see comments made on your pics and/or profile.

ITGS Super Map!

We got the Death Star!

-Authenticity-

The Death Star is the empires most powerful battlestation! Siths may not just enter the "Moon" but they must give some sort of identity to allow them to do such. If you try to enter a room or go up the elevator, you must punch in some codes.

Comp. Inter-ACTION!!

Computers, computers, computers. That, if not at school, is where i spend most of my time. The computer contains everything--especially the internet! When i need to do homework like a research paper, i use the internet and then also microsoft word. Even if i have to just write a response paragraph, it needs to be typed up.

I also use the computer for fun. For example, i would go on facebook, see my friends on and then chat with them. I would also just go on yahoo! , cnn, or bbc (depending on my mood) and see whats going on in the world.
