10 Types of Computers: Part 1

Wearable Computer

The latest trend in computing is wearable computers. Essentially, common computer applications (e-mail, database, multimedia, calendar/scheduler) are integrated into watches, cell phones, visors and even clothing. For more information see these articles on computer clothing, smart watches and fabric PCs.

Super Computer

This type of computer usually costs hundreds of thousands or even millions of dollars. Although some supercomputers are single computer systems, most are comprised of multiple high performance computers working in parallel as a single system. The best known supercomputers are built by Cray Supercomputers.


In the early days of computing, mainframes were huge computers that could fill an entire room or even a whole floor! As the size of computers has diminished while the power has increased, the term mainframe has fallen out of use in favor of enterprise server. You'll still hear the term used, particularly in large companies to describe the huge machines processing millions of transactions every day.


A computer that has been optimized to provide services to other computers over a network. Servers usually have powerful processors, lots of memory and large hard drives. The next type of computer can fill an entire room.


Another type of computer is a workstation. A workstation is simply a desktop computer that has a more powerful processor, additional memory and enhanced capabilities for performing a special group of task, such as 3D Graphics or game development.

10 Types of Computers: Part 2


The personal computer (PC) defines a computer designed for general use by a single person. While a Mac is a PC, most people relate the term with systems that run the Windows operating system. PCs were first known as microcomputers because they were a complete computer but built on a smaller scale than the huge systems in use by most businesses.


A PC that is not designed for portability is a desktop computer. The expectation with desktop systems are that you will set the computer up in a permanent location. Most desktops offer more power, storage and versatility for less cost than their portable brethren.


Also called notebooks, laptops are portable computers that integrate the display, keyboard, a pointing device or trackball, processor, memory and hard drive all in a battery-operated package slightly larger than an average hardcover book.


Netbooks are ultra-portable computers that are even smaller than traditional laptops. The extreme cost-effectiveness of netbooks (roughly $300 to $500) means they're cheaper than almost any brand-new laptop you'll find at retail outlets. However, netbooks' internal components are less powerful than those in regular laptops.


Personal Digital Assistants (PDAs) are tightly integrated computers that often use flash memory instead of a hard drive for storage. These computers usually do not have keyboards but rely on touchscreen technology for user input. PDAs are typically smaller than a paperback novel, very lightweight with a reasonable battery life. A slightly larger and heavier version of the PDA is the handheld computer.

Weird World Wonders: Part 1

Shilin, China

Shilin translates to “stone forest,” and this set of karst formations in southwestern China’s Yunnan Province really does look like a forest of stone. The stone pinnacles, some of which reach nearly 100 feet toward the sky, are believed to be more than 270 million years old.

Baobab Trees, Madagascar

Madagascar's baobab trees look as if they prefer to sprout their roots out the top, especially during the dry season, when they shed their leaves. The trees put those thick, cylindrical trunks to good use storing precious water.

Mud Volcanoes, Azerbaijan

Along the coast of the Caspian Sea in Azerbaijan are more than 300 mud volcanoes which are basically mini-volcanoes made of mud. The bizarre geological phenomena usually belch mud and gases fairly peaceably, but they can turn violent: In 2001, a mud volcano a few miles from the capital, Baku, spit fire nearly 50 feet in the air.

Great Blue Hole, Belize

The Great Blue Hole in the coast of Belize is a giant sinkhole nearly 1,000 feet across and more than 400 feet deep that almost looks like it wants to drag victims to the center of the Earth. But this hole is a gentle giant; divers visit daily to swim among fish and ancient stalactites.

Chocolate Hills, Philippines

The island of Bohol is home to hundreds and hundreds of closely clustered limestone domes called the Chocolate Hills because of their carpet of grass, which turns brown in the dry season.

Weird World Wonders: Part 2

Socotra, Yemen

The island of Socotra, at the mouth of the Gulf of Aden, has been called the most alien-looking place on Earth. The most bizarre of the bunch is the dragon’s blood tree, which looks like a big stalk of broccoli and has red blood — dark red resin, that is.

Split Apple Rock, New Zealand

Interesting rock formations are abundant in Abel Tasman National Park on New Zealand's South Island, but none is weirder than Split Apple Rock, rising from the water of Tasman Bay. The giant boulder has been broken in two pieces so cleanly that it’s almost as if a giant hit it with an axe.

White Desert, Egypt

Western Egypt's White Desert gets its name from the chalk that whitewashes the place. The chalk stands tall in formations that have been eroded by sandstorms into fantastic shapes — mushrooms, spires, pinnacles and anvils.

The Giant's Causeway, Northern Ireland

It just doesn’t look like something nature would have created on its own. But that’s exactly what it is — a field of thousands and thousands of basalt columns formed by ancient volcanic activity. Follow in the giant’s footsteps with a trek down the causeway to the sea.

Devils Tower, Wyoming

It seems almost inevitable that a natural feature as unearthly as Devils Tower might be considered supernatural. Scientists aren’t sure how the monolith was formed, but they agree the rock came from within the Earth, not from another planet.

Some of the World's Rarest Birds

Asian crested ibis

The Asian crested ibis once thrived in Russia, Japan, and China, but its population has shrunk to about 250.

Red-crowned Crane

In the spring and summer, the Red-crowned Crane breeds in Siberia and occasionally in northeastern Mongolia. Normally the crane lays 2 eggs, with only one surviving. Later, in the fall, it migrates in flocks to Korea, Japan, China, Taiwan, and other countries in East Asia to spend the winter.

Marvelous Spatuletail

Peru's marvelous spatuletail. A stunning hummingbird restricted to just two sites, the bird's population is estimated to be less than a thousand.

Orange-bellied parrots

Orange-bellied parrots breeds only in southwestern Tasmania and migrates to southeastern Australia in the winter, where agriculture and development are crowding out its habitat. Probably fewer than 150 animals remain in the wild, according to BirdLife International.


One of the rarest birds of all is New Zealand's kakapo. Only 124 animals remain in the wild—the species has been largely wiped out by introduced predatory mammals such as feral cats.

World's Biggest Stuff: Part 1


The Bawabet Dimashq, also known as the Damascus Gate restaurant, in Damascus, Syria, is the largest in the world, with 6,014 seats. What’s on the menu? Just about everything. The huge restaurant complex has six culinary themed sections for Indian, Chinese, Arab, Iranian, Middle Eastern and Syrian cuisine. Local specialties include lamb with thyme, steak with yogurt and beans, tabbouleh, hummus and baba ghanoush. During busy summer months, the restaurant employs up to 1,800 people in the dining area and kitchen.

Roller Coaster

Kingda Ka roller coaster at Six Flags Great Adventure in Jackson, N.J., is the tallest and fastest roller coaster in the world. The train climbs to 456 feet and can accelerate to 128 mph in 3.5 seconds. The thrill ride travels 3,118 feet and lasts 59 seconds.


Georgia Aquarium in Atlanta, which opened in 2005, is the world’s largest, with 8 million gallons of water. It contains the largest collection of giant groupers, potato groupers, humphead wrasses, tarpons, giant trevallies, batfish, sawfish, blacktip reef sharks, giant hammerhead sharks and wobbegong sharks in an aquarium. It’s also the only aquarium outside of Asia to house whale sharks, the world’s largest fish.


Mount Everest, 29,029 feet, is the world’s highest mountain and is in Nepal. In 1953, New Zealand’s Edmund Hillary and Nepal’s Tenzing Norgay were the first to reach the summit.


The world’s biggest tree is General Sherman, a giant sequoia that’s 275 feet high with a trunk volume of about 1,487 cubic meters. You’ll find it in Giant Forest within Sequoia National Park east of Visalia, Calif. General Sherman is believed to be between 2,300 and 2,700 years old.

World's Biggest Stuff: Part 2

Swimming Pool

The world’s largest swimming pool is the San Alfonso del Mar seawater pool in Algarrobo, Chile. It is 3,324 feet long, longer than 20 Olympic-sized swimming pools laid end to end. Water from the neighboring Pacific Ocean is heated to a comfortable 79 degrees Fahrenheit for swimming. Sports enthusiasts can sign up for classes in swimming, sailing, kayaking and scuba diving.

Cruise Ship

Royal Caribbean’s Oasis of the Seas debuted in December 2009 as the world’s largest cruise ship. It’s nearly five times the gross tonnage of the Titanic, 1½ times longer than the U.S. Capitol building, has 16 decks and has a capacity for 6,296 guests. At 1,187 feet long, 208 feet wide and 213 feet in air draft, it’s too long, too wide and too tall to fit through the Panama Canal.


Dubai, United Arab Emirates, opened the world’s tallest skyscraper in January 2010, and superlatives have poured in ever since. If you stuck the Eiffel Tower on top of the Empire State Building, you still wouldn’t have a structure as tall as the Burj Khalifa. It rises 2,717 feet from the desert and provides views of the Persian Gulf, the sail-shaped Burj al-Arab hotel and the manmade Palm Jumeirah island.


Blue whales, on average, weigh 176 tons. Their tongues alone are as heavy as an elephant. They reach these behemoth proportions on a diet of tiny shrimplike animals called krill.


The largest ancient castle in the world is Prague Castle in Prague. Built in the ninth century, it is an oblong irregular polygon with an average diameter of 420 feet and a total surface area of 18 acres. At times, it has housed the kings of Bohemia as well as Holy Roman emperors and presidents of Czechoslovakia. After Czechoslovakia split into the Czech Republic and Slovakia in 1993, the castle became the seat of the head of state of the new Czech Republic.

Top 10 Websites that Changed Everyday Life Part 2

10. Craigslist
Before the Internet if you ever had interest in a classified ad, you’d probably go straight to the local newspaper and see what you can find. Of course then the Internet came along and while you could find classified ads online, most of the websites were filled with spam posts or people looking to set you up while others were just unorganized and most of the time classified ads for smaller locations were nonexistent. However, today, if you’re ever looking for anything, and I mean anything, all you need to do is go to Craigslist.
You can find plenty of things on the classified ads website; from cars, to pets, to jobs, homes, and even a place to discuss anything you have on your mind. Despite recently coming under fire for its “personals” section of the website, Craigslist continues to be extremely popular among people all around the world. You can find ads in your state and then narrow down to a city which makes finding what you need much easier.
But, just like older classified ads websites, you will find spam ads and you will run into ads that are created by people looking to get your money and run. The website offers a service to report spammers and often shows a warning page explaining how many scammers work and what to look out for when using the site.

9. Yahoo
Yahoo! was founded by Jerry Yang and David Filo in January 1994 and was incorporated on March 1, 1995. Yahoo provides services via the Internet worldwide. The company is perhaps best known for its web portal, search engine (Yahoo! Search), Yahoo! Directory, Yahoo! Mail, Yahoo! News, advertising, online mapping (Yahoo! Maps), video sharing (Yahoo! Video), and social media websites and services. Yahoo! also offers social networking services and user-generated content in products such as My Web, Yahoo! Personals, Yahoo! 360°, Delicious, Flickr and Yahoo! Buzz. In December 2010, reports emerged that Yahoo! would be shutting down Yahoo Buzz, MyBlogLog, Delicious and a handful of other products. Yahoo! Photos was shut down on September 20, 2007, in favor of Flickr. The first logo was used when the company was founded in 1995. It was red and had three icons on each side. Yahoo! is known across the world with its multi-lingual interface. The site is available in over 20 languages, including English. The official directory for all of the Yahoo! International sites is world.yahoo.com. The logo used on the main page yahoo.com used to be red with a black outline and shadow, but in May 2009, along with a new theme redesign, the logo was changed to purple with no outline or shadow. Sometimes, the logo is abbreviated with Y!.

8. Blogger
Blogging is the way of the world now. Who needs to scribble in a personal diary or to write random things on ripped pieces of notebook paper when you can hop on your computer, log in, and type all of your thoughts onto your computer screen, press upload, and have the opportunity to have the entire world read what you’ve got to say. Blogger was launched in 1999 and since then has allowed the blogging world to flourish.
While many want to credit LiveJournal or some other blogging site with raising the bar in the blogging world, Blogger most definitely came first and is often credited for setting the stage for the format of a common blog. The website has been designed and redesigned and most recently has begun to work closely with Google to include some of their most popular features.
The website on the Alexa scale is ranked #8 and each day over 388 million words are published on the website. Even though competitor websites such as WordPress, LiveJournal, and TypePad have come about, Blogger is easily credited with starting the blogging revolution.

7. Pandora
The way we listen to music has drastically changed over time. Today MP3s and MP4s are the way of the world, but let’s not forget records, music cassettes, and of course, the radio. However, even though MP3s and digital music seem to be the latest fad, Pandora has stepped up and offered a way to listen to music online while you surf.
Pandora is an online radio station that basically lets you create your own station based on the music like you like to listen to. Of course, listening to music on the Internet isn’t something new, but being able to create your own music station is. Anyone can tune into music that is played on Yahoo or listen to your favorite radio station online, but the fact is that most of those songs are played every hour (or so it seems) and sometimes the song playing isn’t one that you particularly care for.
But, when it comes to Pandora, website will play a song and based on whether you like the band or not, the website will play similar music. The great thing is that Pandora often throws in new bands that are on the rise. You can easily type in a band on the website, listen to a song, and then have the chance to listen to a new band that is similar to your tastes.

6. Facebook
First there was the telephone, then pagers, then cell phones, then along came the internet with instant messaging services and chatrooms, and before all of this when people wanted to communicate, there was conversational speaking and letters. Today, we have Facebook, and this one social networking site has seriously taken the world by storm. Though technically not the first social networking site created, many will argue that it is the most useful and is the one that has made the largest impact on our society.
It seems like everything we do is based on Facebook these days. Pictures, friends, relationships, gossip; it all ties into Facebook in some way of another, and wherever you go, you’ll usually find something Facebook-esque. Musicians are asking fans to add them on Facebook as are authors, political candidates, businesses, and anything and everything between.
The website was launched in February 2004 by Mark Zuckerberg six years later the website has exploded, attracting more than 500 million users, ranging from your average Joe, to celebrities, and even political world leaders.

Top 10 Websites that Changed Everyday Life Part 1

Before Wikipedia came along, high school and college students had to do their own research the hard way. In all seriousness, before Wikipedia became one big booming e-encyclopedia, many of those that were offered online either required a paid membership to have access to information or the encyclopedia altogether lacked a lot of information. It was either go to the library to find the research you needed or dish out some money to get it.
However, Wikipedia changed all of this and really made research a breeze. The website became the first of its kind: a free e-encyclopedia that has grown and will probably continue to do so as long as the Internet is available. On April 16, 2010, the website had its 1 billionth edit and today it is ranked the #7 most visited website by Alexa. In the U.S. it is the 6th most visited website in the country.
The amazing thing about Wikipedia is that you can literally fin anything and almost everything on Wikipedia. With 3,410,052 articles and growing, there isn’t much you can’t find. If you can’t you can easily edit and add information yourself. The website appeals to Internet users from all over the world, offering information in various languages such as Spanish, Russian, French, German, Italian, and many others. And yes, Wikipedia has a Wikipedia page.

When you need food, you go to the grocery store. When you need clothes, you go to the mall or your favorite retail store. If you need pet supplies, you go to the pet store. If you want to listen to music, you go purchase a CD at a store. All of this is common sense, and generally when people need things, they visit a brick and mortar store. However, when Amazon was launched in 1995, the company, based out of Seattle, changed the entire face of retail shopping. Their name says it all; Amazon is the largest river in the world and Amazon.com is the largest online store on could imagine. Where else can you buy jewelry, MP3s, clothing, vitamins, dog toys, and anything else from the same location?
Most recently Amazon even began selling food products that can be delivered to your door. With the creation of Amazon, it’s safe to say that less and less people are visiting brick and mortar stores to purchase certain items. The website offers free shipping with a $25 purchase as well as a Prime account which promises free 2-day shipping or $3.99 next day shipping. The point is, anyone can count on Amazon to have what they need. It’s truly amazing how an e-shop can stock and supply such a wide array of items.

When it came time to looking or watching videos online, there wasn’t a wide variety of options. At times people would upload videos for people to watch, but many times due to bandwidth and other factors, those who owned websites just opted to stay away from the videos and other high bandwidth features. However, an easy fix to this problem came about in February 2005. YouTube, which has been successfully running for 5 years now, solved any and all problems when it came to entertainment on the Internet. Not only can you watch videos but you can also listen to music and even blog through videos.
Millions of people from all over the world enjoy the features of YouTube each day. Because of YouTube there is one great place for everyone to look at videos and even comment and review them. The website allows you to really watch anything you could ever think of. From music videos to bloggers, to tutorials and just outright random videos, you can surely find it on YouTube.
The website is ranked #3 on the Alexa scale and offers 29 different languages for users who live outside of the United States. Though other video websites are available, such as Hulu, none have been as successful as YouTube has been.

While online shopping has become a great fad that it seems everyone has latched onto, eBay is one of many websites that should have credit for advancing this online phenomenon. Even though most websites today offer users the ability to purchase what they want online, eBay not only offers online shopping it also allows users to bid on some of the hottest items each year. eBay has most definitely made shopping something that anyone can do without having to get in the car, drive to a store or the mall, and then look around to find the right size or color.
With online shopping with a few simple clicks your shopping is done. eBay allows users from all over the world to bid and buy items. The good thing about the website is that many times you pay a lot less than you would in stores and even better is the fact that items are available that may not be sold in a store local to you. eBay has made it easy to find some of the most popular items as well as items that aren’t sold in stores anymore.
eBay is also well known for its ability for users to sell various items, from perfume to clothing to shoes and anything and everything in between. eBay is one of the very few websites that offers live real time auctions for products.

As extreme as it sounds, it’s pretty safe to say that when it comes to the Internet Google can be found anywhere and everywhere. No matter what kind of activity you do online, from watching videos, to blogging, to just reading the local news online, you’re probably some way, somehow using a service provided by Google, and many times you don’t even know it. When you watch a YouTube video, you’re using a Google service. If you’ve ever used Blogger, that’s a Google service. Chrome: Google browser. If you’ve ever seen a Doubleclick ad; yep, that’s Google too.
So in essence, Google is everywhere; ubiquitous. From watching videos to uploading pictures to show to friends and family, whether you know it or not, Google is a very well used service all over the world. If you ever need to get somewhere, you probably go to Google.com. If you need to search for something, Google.com is probably the first place you go.
