What does the Net know?

Posted in Uncategorized on January 29, 2010 by alangalvan

1) What is a DVD? Digital Versatile Disc or Digital Video Disc, is an optical disc storage media format.

2) How does a microprocessor work? A microprocessor (also known as a CPU or central processing unit)
is the central processing unit in a computer. It receives, transmits and coordinates every command and process carried out by the system. Electrical currents, moving through wires and transistors, are converted into usable messages through the use of a Boolean logic language. Based on the “on/off” frequency of current moving through transistor circuits, this Boolean logic communicates system commands to and from receiving devices within the computer. The microprocessor communicates within two primary capacities: logic and the processing of information. These processes are handled by two components within the chip:
*Arithmetic logic unit (ALU), responsible for all commands requiring an arithmetic or logic function
* Control unit (CU), which handles the information processing from the computer’s memory.

3) What does LCD mean? LCD stands for Liquid Crystal Display. There is a set of two transparent panels with a liquid crystal solution between them. Light is shined from behind the panels. Each crystal either allows light to pass through or blocks the light. The configuration of the crystals forms the image.

4) How does the internet work? The Internet is a global network of computers which allows people to exchange data worldwide instantaneously. The Internet spreads across all seven continents and includes computers that range from 35 year-old mainframes to modern home PCs to handheld devices. These computers connect to the Internet via a tremendous array of communications mediums including phone lines, coaxial television cable, fiber optic cable, serial lines, short-range (in-building) wireless signals and long-range (cellular) wireless signals. Even with all this variance, the technology of the Internet allows a 10-ounce handheld computer to exchange data with a room-sized mainframe from the 1970’s.

5) Is graffiti art? The problem with graffiti art is the question of whether it’s really art, or just plain vandalism. This isn’t always an easy question to answer, simply because there are so many different types of graffiti. Some is simply a monochrome collection of letters, known as a tag, with little artistic merit. Because it’s quick to produce and small, it is one of the most widespread and prevalent forms of graffiti…

6) What is a yellow dog? A socially conservative and economically liberal person

7) What is a blue dog? A conservative member of the Democratic Caucus

8 ) How does planting trees help the environment? Trees are like the lungs of the planet. They breathe in carbon dioxide and breathe out oxygen. Additionally, they provide habitat for birds and other wildlife. But that’s not all trees do for us! To see just how much trees are essential to the planet and to humans, let’s look at the following statistics:

CO2 is one of the major contributing elements to the greenhouse effect. Trees trap CO2 from the atmosphere and make carbohydrates that are used for plant growth. They give us oxygen in return. According to, about 800 million tons of carbon are stored in the trees that make up the urban forests of the U.S. This translates to a savings of $22 billion in control costs. Mature trees can absorb roughly 48 pounds of CO2 a year. The tree in turn releases enough oxygen to sustain two human beings.

9) What is bamboo? bamboo are a group of perennial evergreen (except for certain temperate species) plants in the true grass family Poaceae, subfamily Bambusoideae, tribe Bambuseae. Giant bamboos are the largest members of the grass family.

In bamboo, wheat and other grasses, the internodal regions of the plant stem are hollow, but the vascular bundles, as seen in cross section, are scattered throughout the stem instead of in a cylindrical arrangement. Secondary, dicotyledonous woody xylem is absent. The absence of secondary growth, wood, causes the stems of monocots, even of palms and large bamboos, to be columnar rather than tapering.[1]

Bamboos are also the fastest growing plants in the world. They are capable of growing up to 60 centimeters (24 in.) or more per day due to a unique rhizome-dependent system. However, this astounding growth rate is highly dependent on local soil and climatic conditions. Bamboos are of notable economic and cultural significance in East Asia and South East Asia where they are used extensively in everyday life as building materials, as a food source and as a highly versatile raw product.

10) What is MLA format? All fields of research agree on the need to document scholarly borrowings, but documentation conventions vary because of the different needs of scholarly disciplines. MLA style for documentation is widely used in the humanities, especially in writing on language and literature. Generally simpler and more concise than other styles, MLA style features brief parenthetical citations in the text keyed to an alphabetical list of works cited that appears at the end of the work.

MLA style has been widely adopted by schools, academic departments, and instructors for over half a century. The association’s guidelines are also used by over 1,100 scholarly and literary journals, newsletters, and magazines and by many university and commercial presses. The MLA’s guidelines are followed throughout North America and in Brazil, China, India, Japan, Taiwan, and other countries around the world.

11) What is Adobe Illustrator? Adobe Illustrator is a vector graphics editor developed and marketed by Adobe Systems.

12) What’s the difference between a vector and a raster graphic? The difference between vector and raster graphics is that raster graphics are composed of pixels, while vector graphics are composed of paths. A raster graphic, such as a gif or jpeg, is an array of pixels of various colors, which together form an image. A vector graphic, such as an .eps file or Adobe Illustrator? file, is composed of paths, or lines, that are either straight or curved. The data file for a vector image contains the points where the paths start and end, how much the paths curve, and the colors that either border or fill the paths. Because vector graphics are not made of pixels, the images can be scaled to be very large without losing quality. Raster graphics, on the other hand, become “blocky,” since each pixel increases in size as the image is made larger. This is why logos and other designs are typically created in vector format — the quality will look the same on a business card as it will on a billboard.

13) Who are you? he must be a blogger because he has a facebook, myspace, and a blog. He must also be mexican.

” Este es el perfil público de Alan Galvan (Tamaulipas, México) en Sonico. Alan Galvan tiene 22 amigos en Sonico.”

“Jovanni Alan Galvan Soto is on Facebook.”

“MySpace profile for Alan Galvan. Find friends, share photos, keep in touch with classmates, and meet new people on MySpace.”

Apple has released some new things, one of these new things is the A4 CPU. It has a speed of 1GHz  and multicore architecture. The A4 is composed of that Cortex barnburner, an integrated memory controller, and the Mali 50-series GPU.

Another thing Apple released is the IPad. It’s a half-inch thick and weighs just 1.5 pounds, with a 9.7-inch capacitive touchscreen IPS LCD display, and it’s running a custom 1GHz A4 chip, with a 10-hour battery life and a month of standby. It’ll come in 16, 32, and 64GB sizes. There’s a 30-pin Dock connector, a speaker, a microphone, Bluetooth, 802.11n WiFi and optional 3G, as well as an accelerometer and a compass. It starts at $499 for 16GB, 32GB for $599, and $699 64GB.

iBookstore will be available in the US at launch.

This might change my life because it can replace my laptop. If I get one I would carry it around everywhere since it is almost like an ipod touch with a giant screen. The only difference is that it doesnt fit in your pocket.

Nexus One

Posted in Uncategorized on January 19, 2010 by alangalvan

The Nexus One is a new smartphone from google. The phone comes unlocked and is not restricted for any mobile network provider. Google currently offers it for T-Mobile and a Verizon version is expected in the second calendar quarter of 2010. The Nexus One was released one January 5, 2010.

The phone is sold via Google’s website at the price of $529 or a subsidized $179 at T-Mobile with a 2 year contract.

The Nexus One has a 5 megapixel camera and flash. Google also bumped up the speed of the camera app. Google just gave Motorola (and Verizon) a swift shot to the TSTS, because the Nexus One is astonishingly faster than the Droid. When comparing the three phones in loading a webpage over Wi-Fi, the Nexus One loaded first, the iPhone 3GS came in a few seconds later, and the Droid came in a little while after that. This was constant throughout many webpage loads, so it’s indicative of something going on inside with the hardware.

The Nexus One has animated video backgrounds, but they’re actually more than just animations: you can interact with them.

“If Google’s planning on releasing this phone as their official Google Phone, it’ll certify them as the premium Android phone brand out there right now” – Jason Chen, Gizmodo
