Computers:
First Computer Invented:
Most people when they think of first computer invented they think Bill Gates. This, however, is not true, for the computer was invented long before Bill Gates was around. Bill Gates only revolutionized the computer, buy creating a more compact and useful form of the computer and making it available to everyone with a job.
There are many people out there who would say that the first "computer" was the abacus, invented in Asia about 5000 years ago. I however, wouldn't.
The first of the "modern" computers was invented during World War II, in 1941 by a German engineer named Konrad Zuse. Its name was the Z3 and it was used to help design German airplanes and missile's. Then in 1943, the Allied forces developed a computer called Colossus. It helped decode German messages.
The Mark I, designed by Howard H. Aiken, an engineer working with Harvard and IBM. The Mark I was positively huge, taking up half of a football field. It was useful though and it helped to create ballistic charts for the US Navy during the war.
Shortly after this, came the Electronic Numerical Integrator and Computer (ENIAC), developed by John Presper Eckert and John W. Mauchly, working with the government and the University of Pennsylvania. ENIAC was about 1000 times faster than The Mark I but no smarter.
The Use of transistors, ment computers that could store memory and even run programs. Soon after computer languages were invented so that people could change the programs run by the computer. Finally computer research brought us smaller, more useful computers, and eventually the kinds of computers that we have today.
First Laptops Invented:
Although it is a little hard to determine what the first portable or laptop computer was, and when it was invented, we can however say that there is more than one claim to laptop fame. There was even signs of laptops dating back as early as 1979. Designed by a Briton, William Moggridge, for use by NASA in early 1980's. IT was one fifth the weight of any model equivalent in performance and was a 340K byte bubble memory lap-top computer with die-cast magnesium case and folding electroluminescent graphics display screen.
Since then notebook PC's released in 1981 lay clam to being the first. It was the Epson HX-20, a battery powered portable computer, with a 20-character by 4 line LCD display and a built-in printer that started the new widespread desire for these laptop computers.
In January of 1982, Microsoft's Kazuhiko Nishi and Bill Gates begin discussions on designing a portable computer, based on using a new liquid crystal display or LCD screen. LCD technology in 1982? Yeah that's right! Believe it or not we had the technology to make the LCD tvs and monitors that you've seen only recently over 22 years ago. But that's another story in itself.
First PDAs Invented:
First of all PDA stands for personal digital assistants in case you didn't already know. In 1993, Apple Computer Inc. released the very first PDA(personal digital assistants) "The Newton®". For the next three years, PDA sales dwindled, and were almost off the charts. Then, in March 1996, Palm™, Inc. delivered the industry's first truly compelling handheld computer, the PalmPilot. Today there are to many PDA companies and products to even bother mentioning.

First Television Invented:
The first signs of a tele date back to the 1862 when Abbe Giovanna Caselli invents his "pantelegraph" and becomes the first person to transmit a still image over wires. In 1900, at the World's Fair in Paris, the 1st International Congress of Electricity was held, where Russian, Constantin Perskyi made the first known use of the word "television." In 1930 Charles Jenkins broadcasts the first TV commercial. The BBC begins regular TV transmissions.
Then throughout the years the inventions came one after another. In 1950 the FCC approves the first color television standard which is replaced by a second in 1953. Vladimir Zworykin developed a better camera tube - the Vidicon. In 1956 Robert Adler invents the first practical remote control. In 1973 giant screen projection TVs are first marketed. Followed by Sonys release of the first home video cassette recorder in 1976.By time 1996 came around there was a billion TV sets world-wide.
First DVD/Player Invented:
We can only assume the transition over from cd's and cd players over to dvds and dvd players wasn't that hard. The technology was already there for them. So the dvd player was surely invented before or right after the dvd was invented. DVDs are the work of many companies and many people. The DVD evolved from CD and related technologies. Companies such as Sony, Philips, Toshiba, Matsushita, Time Warner, and others announced the new "high density" dvd in September of 1995.

Basic Technology History
Directv HD Receivers Moving With Times
by: David Johnson
Directv’s debut in 1994 turned out to be an auspicious entry into the satellite television market. With a variety of options in programming, some cable subscribers opted for satellite and now more and more are doing so, while others are taking the next technological step by purchasing Directv’s HD receivers as well.
And with the FCC handing down a decision to convert all television to high definition format, commonly known as HD, by 2006, content providers, cable and satellite companies like Directv are in full swing with marketing programs to sell their HD receivers. HD is broadcast digitally at a higher resolution for better picture quality. In the past high definition television used to be a term referred to newer technology in the 1930s that replaced experimental television technology at the time.
Currently, a Directv HD receiver can cost in the five hundred to six hundred dollar range on the cheap side and well over a thousand dollars for higher end receivers. Electronics manufacturers like Hughes, Samsung and others are all touting their HD receivers now for their features, but prices are still a little high, as well as for HD television sets, which average in price over one thousand five hundred dollars
Much has been made of the high definition issue of late and those with a more pessimistic mindset toward HD, some refer to them as hardcore analogue-ers, don’t think a full conversion to HD will be done in time. Even now, those who may purchase an HD receiver are limited to those providers, or television stations or networks that provide content in HD, which some say is up to five times sharper than regular television.
But while Directv has done its part by offering HD receivers, customers recently have complained about the exorbitant price of an HD and Tivo combination receiver, which rings in at a thousand dollars when purchasing it from Directv, a hard pill to swallow for those who may have already spent five hundred to a thousand dollars on a Directv HD receiver to begin with. Tivo allows customers to records hours of television without needing a VHS tape or DVD burner. For the time being some customers are buying a separate Tivo unit and hooking it into their current Directv HD receiver, unfortunately sacrificing some picture quality along the way.
But many customers feel that in time, as with the prices of plasma screen televisions, the Tivo and Directv HD receiver combination will come down in price. So for now, the best bet for those with their Directv HD receivers may be to wait. In time, not only will there be more HD content, but also more affordable receiver options. Standard Directv HD Receivers will likely go down in price as well, along with those with the added Tivo option.

The Apple of my Eye
by: Warren Thompson
It appears that Apple has done it again, folks! I’m sure you have all seen the television commercials, or heard the radio spots, or viewed the ads on your computer. The little company that could has done it again, with the introduction of the iPod Video. Does it really come as such a surprise, though?
It seems that Apple is a company that cannot fail. Sure, they had some difficult times in the past. With so many aggressive plays by Microsoft back in the day, it is unlikely that any tech company would have weathered them with ease. But Apple has always had something that all of Bill Gate’s money could never buy; a true connection with their users.
Since introducing the iPod a few years ago, Apple has seen steady and sustained growth that does not appear to be waning anytime soon. Especially, as they seem to update the iPod every few months now. Dammit, I just bought my iPod Mini a few months ago and they have discontinued it already! They didn’t simply discontinue it, though. They replaced it with the iPod Nano, which is smaller, slicker, and has a color screen. I wanted one as soon as I saw it, or at least until I saw the iPod Video.
Now Apple has introduced to much fanfare, the iPod Video! I was certain that the next iPod would have a video camera in it, but perhaps they are saving that for next month. Steve Jobs, the CEO of Apple, didn’t seem too keen on the idea of a video iPod a few short years ago. Funny how things change, huh? They have also announced a partnership with Disney, in which they will provide customers with Disney’s feature films through the iTunes store. You can be sure that Pixar films are on the way, too.
The new iPod Video comes in 30 and 60 Gigabyte models with color screens. You can now store music, graphics, pictures, and video on your iPod. It also comes with a video output that will allow you to hook it up to your television or video projector. I can hardly believe all of the features that the iPod now has. I suspect that the inclusion of a video camera and a cell phone with give Apple complete market domination. They should be out in a couple months, or so one would think. The only thing missing after that would be a Star Trek-type teleporter! Remember, you heard it here first!

The Science Behind DLP Television
by: Mitchell Medford
DLP televisions are based on a technology invented by Texas Instruments back in 1987 called Digital Light Processing. The technology is based on an optical semiconductor called DMD (Digital Micromirror Device) chip. It is a highly reliable, all-digital display chip that delivers the best picture across a broad range of products, including large screen digital TVs, and projectors for business, home, professional venue and digital cinema.
The chip consists of over one million mirrors to process light. They come in either single chip or 3 chip configurations. One-chip DLP systems use a projection lamp to pass white light through a color wheel that sends red-green-blue colors to the DMD chip in a sequential order to create an image on-screen. Only one DMD chip is used to process the primary RGB colors. Three-chip DLP systems use a projection lamp to send white light through a prism, which creates separate red, green, and blue light beams. Each beam is sent to their respective red, green, and blue DMD chip to process the image for display on-screen. One-chip models are said to produce a display of over 16-million colors. Three-chip models can produce a display of over 35-trillion colors. The result is maximum fidelity: a picture whose clarity, brilliance and color must be seen to be believed.
When a DLP chip is coordinated with a digital video or graphic signal, a light source, and a projection lens, its mirrors can reflect an all-digital image onto a screen or other surface. The DLP chip and the sophisticated electronics that surround it are what we call Digital Light Processing™ technology.
Benefits of Single chip DLP:
1. Fantastic color accuracy.
2. The best contrast ratios and shadow detail.
3. Generally very quiet.
4. Very little space between each pixel creates a very smooth image, even when using lower resolution projectors.
5. Light engine failures are very rare so repairs are less costly than other technologies.
6. Technology doesn't degrade over time. With proper routine maintenance, DLP™ projectors consistently provide just-out-of-the-box performance. (DLP™ is the only technology that makes this claim).
Benefits of Three chip DLP:
1. Good contrast; much greater than film theaters.
2. Good shadow detail.
3. Can provide high brightness compared to the limited brightness of single chip versions.
4. Overall image quality deemed as the best of any type of micro display technology.
5. Same technology as projectors installed in digital theaters.
6. Pure digital technology.
The bit-streamed image code entering the semiconductor directs each mirror to switch on and off up to several thousand times per second. When a mirror is switched on more frequently than off, it reflects a light gray pixel; a mirror that's switched off more frequently reflects a darker gray pixel. In this way, the mirrors in a DLP projection system can reflect pixels in up to 1,024 shades of gray to convert the video or graphic signal entering the DLP chip into a highly detailed grayscale image.
The white light generated by the lamp in a DLP projection system passes through a color wheel as it travels to the surface of the DLP chip. The color wheel filters the light into red, green, and blue, from which a single-chip DLP projection system can create at least 16.7 million colors. And the 3-chip system found in DLP Cinema™ projection systems is capable of producing no fewer than 35 trillion colors. The on and off states of each micromirror are coordinated with these three basic building blocks of color. For example, a mirror responsible for projecting a purple pixel will only reflect red and blue light to the projection surface; our eyes then blend these rapidly alternating flashes to see the intended hue in a projected image.

Home Theatre
by: Andrew A
With all of the technology that is available for people to be able to make their family or living rooms into their own personal home theaters, many people are deciding that a television, no matter how large it is, is simply not enough to complete their home theater experience. A new line of comparatively small and inexpensive digital home theater projectors is now available for anyone looking for the ultimate home theater experience. People who want to truly experience the atmosphere of the theater can now do so by creating their own miniature screening room complete with a home theater projector.
A home theater project isn’t just for showing movies at home. While videotapes and DVD’s can look amazing when viewed through a home theater projector, television programs, sporting events and even video games viewed through a projector are incredibly entertaining. The price of home theater projectors is very attractive when compared to the latest in big screen televisions and plasma TVs. A home theater project can provide the larger view of television programming often for thousands of dollars less than large televisions.
There are a number of different home theater projectors available to choose from to provide the exact viewing experience each individual desires in their home. It is important to keep in mind when deciding to purchase a home theater projector for the home that it will require a relatively darkened room in order for the images to be seen clearly. Many people can remember seeing the older reel-to-reel projectors that their parent’s showed home movies on for years. Today’s home theater projectors have incorporated digital technology into their design in order to be of a smaller size than traditional projectors and to be able to adjust settings for the perfect image.
Today’s home theater projectors project the light that displays images a number of different ways including the use of a liquid crystal display (LCD), mirrors or a combination of both. Home theater projectors that use a LCD is more likely to be less expensive than other models that use a combination of projection techniques. The most expensive type of home theater projector uses something called Liquid Crystal on Silicon to display images that some people believe to offer the sharpest image from a projector. Once a home theater projector has been chosen, it will require a screen on which to display images or if a person enjoys a challenge, he or she can attempt to construct their own original screen.
Most projectors seem to work best when they are mounted up high or even from the ceiling. Cables coming out of the projector tend to be unsightly and can be hidden inside the ceiling or walls. Hiring a professional to complete this task might be the only way to avoid damage and accidents when attempting to do it alone. Some people find creative ways to conceal the cords by covering them with neutral colored tape and then painting over the tape with the color that matches the ceiling or walls. Other people cover cords with furniture like paintings or bookshelves.
Once a home theater projector has become a part of a complete home theater system, most people rarely opt to use their television for their viewing entertainment. Home theater projectors truly allow for anyone to have their own movie theater right in their own living room.

How Plasma TVs And LCD TVs Differ
by: Joseph Foley
The buying of large-screen TVs has absolutely skyrocketed lately. It seems that everyone wants one – and with good reason. The large-screen TV has come a long way from those faded-out behemoths of old that took up half your living room and never really produced a picture of decent quality. Now, however, especially in combination with HDTV, you can get not only a nice, large picture, but a crisp, clean one too.
Once you decide that you’re ready for a large-screen TV, you quickly discover that you only really have two main options – a plasma TV or an LCD TV. Plasma TVs were first on the scene, but the recent mass production of LCD TVs by major manufactures has put LCD TVs pretty much on equal footing with plasmas. That said, you will still have to make a choice.
If you’re like most people, you not only have no idea how the two differ, you don’t even know the areas you should be considering in order to determine how they differ. But they do indeed differ, and knowing the difference is extremely important if you’re going to get the TV that’s right for you.
You can essentially boil the differences between plasmas and LCDs into twelve basic points. In some areas, plasmas will win out. In other areas, LCDs will win out. In yet other areas, it will depend on your own personal taste in order to decide who wins out.
The twelve ways plasma TVs and LCD TVs differ are the following:
1. The first is a technical issue, and may seem a little boring, but it really does affect other areas. Plasmas TVs are made of chemical compounds called phosphors. LCD TVs use millions of liquid crystals.
2. The next section is related to how big the TVs are and the availability of larger sizes. You have a wider selection of larger-size TVs with plasmas (though LCDs are catching up).
3. The next section is “small size,” which is also important. Plasmas don't come in smaller sizes, which you will need for places like the kitchen.
4. Next is viewing angle. Plasmas tend to have a wider viewing angle (though, again, LCDs are catching up).
5. Although the manufacturers may not like to admit it, each “can” suffer from certain problems. Plasmas can suffer from burn-in effect; LCDs don't.
6. Another problem area, but for LCDs, is “delay.” LCDs can produce a jagged figure when in motion. Plasmas tend to do better. HDTV improves this dramatically for both.
7. The next area is life span. You can replace the light source with an LCD, thereby bringing your original picture back. With plasmas you can't.
8. In the next few sections, the theme of “picture quality” is considered. First, color: LCDs produce sharp, lively colors. Plasmas produce warmer and more accurate colors.
9. Next is brightness levels and the TVs ability to handle different lighting. LCDs tend to do better in bright-light conditions.
10. Also related to picture quality is “black levels.” Plasmas tend to produce blacker blacks.
11. Another area to consider is contrast range. Plasmas, "technically," produce a higher contrast range.
12. Last, and certainly not least, is price. At the moment, plasmas tend to run a little cheaper, but this is changing rapidly as LCDs flood into the market. By the time you read this, in fact, there may be no difference at all.
Essentially, which one is right for you will all comes down to taste: What potential negatives will you not really notice? What positives do you want more of? What do you really want the TV for – movies, sports, news, regular TV shows? Both plasmas and LCDs have strong advocates in their corners. Both have deliriously happy customers. But those happy customers are only happy because they knew what they wanted before they made their purchase. If you want to make the right choice, you’ll have to decide what it is you want and which of the two TVs can best give you that.
