MAC VS. PC

It was discovered that microsoft's Seinfeld ad campaign, which shows people using windows-based PCs was created on a Mac.
This is not very suprising because the Mac is a computer that is aimed towards the creative side of things. The big message that the PC wanted to convey is that all kinds of people use PC for all kinds of things. And they did. The Mac and the PC are both good computers whicha re best used and/or suited to certain people.

Robotics

I know that robotics are beginning to become very advanced. Nissan has introduced a Robot that is self run and self-governing named Nismo. Also scientists have been able to create robotics which can function for themselves because they are connected to sensors so they can respond to the environment. They are hooked up to rat brains which can be used to process the information input from the censors.
I would be very interested in taking a robotics or programming course if it was offered because i find it very interesting.

7-period school day

The 7-period school day will mean people can not take as many classes as before. This does not affect me because i'm a senior and will be graduating.

Sarah Palin get hacked

Sarah palin's e-mail was hacked incredibly easily because all of the information the hacker needed could be found easily on the internet. This would never happen to me because alot of my personal or private information is not released on the internet.

iPhone campaign

The iPhone sells on its online store a 99 cent application that is to keep people updated on what is going on around them in politics. It is a good idea to put the election news and informations on the phone for people who dont have time to catch the election news on the T.V. It offers the presidential blog and polls online for all of the younger demographic because it is phone-based.

The world around us.

People can stay more connected with the world around us is to try to watch the news, visit current websites, or read the newspaper to see and stay in touch with what is going on around us and how it affects us and others.

CERN is Hacked

When CERN was about to test the collider, a underground particle accelarator, a group of hackers who call themselves the "Greek Security Team" hacked into a CERN web page and defaced the webpage with a message in greek which translates to "We're pulling your pants down because we don't want to see you running around naked looking to hide yourselves when the panic comes". This was only done to show CERN its security weakness. The defaced web page was removed.
A big name asscociated with CERN is Tim Berners-Lee, the inventor of the World Wide Web. He is a member of the W3C. He is one of the most involved members of the internet and he was one of the people who was affected by the hacker.

Google Docs

Google Docs is a free, online area where you can make or organize all of your folders, documents, spreadsheets, powerpoints, faxes, pictures, or anything you need for your friends and/or business. You can also take this information and publish it as a webpage and edit or unpublish at any time. You can share your work with others and they can help you check it in real time and make suggestions with the chat box.

Google added to google docs by adding features that let you use the dictionary/thesaurus to look up defintions and synonyms/antonyms of a word. You can also linktot the Brittanica site to look at more detailed descriptions. You can Look up pictures of a selected word. Last you can create a table of contents as your first page.

High capacity compact flashcard

SanDisk introduced its 32 GB CompactFlash card. The New disk is not the fastest but is aimed at users who need more memory space. It is aimed at people who use High-Definition camcorders. The card provides high quality images and can operate in extreme temperatures. This is a new and better version of RAM( random access memory) not ROM( read-only memory). It is RAm not Rom because you can edit and access the memory at any time in any order.

Bill Gates commercial

Microsoft unvieled a commercial in its $300 million multimedia campaign in which Bill Gates and Jerry Seinfield are in a family home in which they are "connecting" with real families. They are trying to get back in touch with the needs of everyday computer users. In the end Bill Gates does the robot

Smart Garment

A Smart Garment is electronic sensors that nike and apple are working on and improving upon which can be used to get feedback from your clothing. A runner could get information from the sensors in his shoes which let him know how many calories he burned or elevation gain. These electronic sensors could also tell the runner how to improve upon the run or alert you when the shoes get worn down before they impair your running.

Open source Software and Linux

Linux is a good Open source software because of its ability to be changed and improved upon since the source codes initial release in 1991. It has grown from a few small c files to 290 megabytes of source. New versions of the Linux kernel are relesed every few years and are maintained by different people.

Open Source Software

Open source software is free software that can be changed by the user because the source code is available by a copyright license. users can change, use, and improve software.

Mainframe VS. PC

Early mainframes were housed in enormous metal boxes or frames. Many mainframes were manufactured from the late 1950s through the 1970s. They used to be common computers used to solve problems and do work for everyone but ever since the PC less mainframes are used and are now only used by large organizations for critical applications, Bulk data processing, industry statistics, ERP, and financial transaction processing. The CPU speed of a mainframe can run from 26 millions of instructions per second(MIPS) to 30,657 MIPS. Technology can join 32 of these computers together and make them behave as a single computer performing at 981,024 MIPS.

PC stands for personal computer. Its price, size, and capabilities make it useful for the individual user. This type of computer runs faster for single people who interests in doing things like going on the internet and using microsoft office. These computers can alsop be better for gamers or Djs. Everything about the PC is mad efor it to be personal. The PC is very affordable, effective and portable, especially if you use a laptop or tablet computer.

RAM, ROM, Virtual Memory and Caching

All four are types of memory but they differ as to what they can do or store.
RAM(Random Access Memory) is a form of computer memory. You can access any memory cell if you know the row and column that intersect at that cell. RAM causes your computer to feel faster to a point and it eliminates the need to "Swap" out programs. RAM will be lost every time the computer shuts down.
http://computer.howstuffworks.com/ram.htm
ROM(Read-Only Memory) is a circuit with preprogrammed data on it. They are used in most electronics. ROM can not be edited, if a mistake is made you must start all over with ROM.
http://computer.howstuffworks.com/rom.htm
Caching is a memory system. It is used to access the memory of the main memory faster that normal. An L2 cache access' the main memory 2x faster than normal and an L1 cache access' the main memory 3.5x faster than the L2 cache. Caches are used between subsystems of the computer to improve performance. This is also used to cache a slow medium like the internet.
http://computer.howstuffworks.com/cache3.htm
Virtual Memory is part of tha RAM which looks for unused memory and copies applications onto the hard disk which frees up space on the RAM to load a new application. The copying of the applications happens automatically and makes the computer feel like it has more memory than it really does. This is also an economic benefit because hard disk space is cheaper than RAM chips.

Contextual Clue

The word is Multitasking. The clues that i saw was ". . it must share its attention in small portions among all the active tasks." This lets me know that multitasking involves doing many things at once.

My Second Assignment

What is Nanotube technology?
Carbon Nanotubes are allotropes of carbon that can be used in applications such as nanotechnology, electronics, optics, and in other fields of material science.

What does it look like?
Carbon Nanotubes are hair-sized tubes made of rolled-up carbon hexagons

What might it mean for future technology?
Nanotechnologycan be used by companies to boost the performance of future microprocessors and computer memory. Technology will be shrunk to even smaller sizes than before to sizes almost a fraction of the width of a human hair.
