The concept of laptops developed when more and more people were clamoring for a portable computer they can work with while traveling and carry it to different locations. The laptops that were initially introduced were somewhat crude and lacked the sophistication of the laptops as we know and see them today. They were very bulky, had very small displays, without hard drives and everything ran from the RAM or floppy disks.
In 1981 the Osborne Computer Company released the first portable computer and called it Osborne 1. This laptop computer, when not in use and closed up, resembled a locked up sewing machine. It was powered by an electrical connection with an optional laptop battery backup. It had two 5 ¼” floppy drives (mounted to the right and left of the display), and included a modem port. The biggest drawback was the display was only 5-inches wide and could show only a limited 52 characters per line.
Then in 1983, Gavilan introduced the Gavilan Mobile Computer. It was peculiarly built and the screen folded over the keyboard when closed. It weighed 9 pounds, and could run on nickel-cadmium batteries for close to 9 hours.
Three years later in 1986,Radio Shack released the TRS – 80 Model 200 This model was more compact, had a much larger display and more effective laptop battery power, and included built-in software. People used this model for creating simple documents and considered it to be pretty high tech at that time.
A year later in 1987, IBM released its version of a laptop computer calling it the 5155 Portable Personal Computer. It had two double-sided 5 ¼” drives and 640K RAM. The 5155 however did not support graphics and was used for the limited processing of text-based information only.
During 1988, Compaq introduced the SLT/286 Laptop which had overcome the graphics barrier. This model however weighed a hefty 14 pounds, had a 1.44 floppy drive and ‘286’ processor. NEC joined the fray with the NEC UltraLite, which weighed just 4.4 pounds and had overall dimensions of 11.75″ (W) X 1.4″ (H) X 8.3″ (D).
Macintosh entered the laptop scenario in 1989 with their Portable that weighed around16 pounds and had a 9.8-inch 640 x 400 active matrix screen. Its redeeming feature was an operation time of close to 10 hours on a lead-acid battery. These early laptops from Macintosh later evolved into the PowerBook line and now the MacBook line.
It was only in the 1990s we saw the faster, sleeker machines with more storage, more ports and connectors, improved displays, and weighing much less and comfortable enough to carry around. The Apple Macintosh PowerBook line and the IBM ThinkPads became major competitors in the laptop market.
Companies now create new laptops with faster processors and more features packed in smaller packages and the laptopshave really come a long long way from the 1981 Osborne model. Since the 90’s the technology has helped to vastly improve the performance of laptop computers. Longer lasting laptop battery as well as huge hard drives now makes the Laptop a serious challenger to oust the desktop computers from the marketThe summer of 1995 was a watershed year in the history of laptop computers. In August of that year Microsoft introduced Windows 95. It was the first time that Microsoft had placed much of the power management control in the operating system. This move held a great deal in simplifying and stabilizing certain key aspects of notebook design. Windows 95 also brought in the importance of the CD-Rom drive in mobile computing, and initiated the shift to the Intel Pentium processor as the base platform for notebooks.
History of Laptops
Written by admin on February 8th, 2010Use Png Images Format in Your Web Designing
Written by admin on February 2nd, 2010The PNG image file format is not new to the web. It originally developed in the mid-90s as a solution to the shortcomings of the traditional GIF image file format. However, because early browser applications offered only spotty support for the PNG’s advanced features, web designers, developers were limited in its use.
One large hurdle in particular faced by PNG’s was Microsoft Internet Explorer (IE). Far and away the most popular browser, IE offered particularly poor support for the file format. However, with the release of IE 7 as well as several JavaScript hacks, this has all changed, and PNGs are more popular than ever.
But who cares!? And besides being one letter short of my favorite 1972 video game, what makes a PNG so great? Below, are three reasons why PNGs are the best image format since the Polaroid.
They’re See-Through! (Alpha Transparency):
As compared to the GIF, PNG offers a far less basic form of transparency. With GIFs, a particular color (or colors) is able to be saved as transparent, leaving colors either entirely opaque or transparent. There is no in-between.
PNGs have a distinct advantage in this area. The PNG file format supports “semi-transparent pixels,” meaning a PNG can be saved with a soft drop shadow and floated over any background. It can be used as a watermark on a textured or gradiented background. It can even be smoothly faded from fully opaque to transparent, revealing the web page contents beneath.
Summerour.net features a logo which demonstrates this function. The homepage layout called for a logo with a soft drop shadow over a textured background of architectural sketches that regularly change. Using a GIF or JPG would be highly impractical, because every time the image changed, the logo is background would need to be edited. A PNG, however, is floated over the image with a faded drop shadow, making the task quick, simple and dynamic. PNGs make the look and feel of your page flexible.
They Look Great! (Lossless Compression ):
Every time a JPEG is saved and compressed, it loses some of the original file’s information and the image quality degrades. The GIF file format offers lossless compression (so the file can be saved and resaved without losing image quality), but it only supports a limited 256 color palette, making it useless for full-color photography and other such complex images.
PNG offers the best of both worlds. It displays full color photographic images, like the JPEG, but it also supports a managed color palette, like the GIF format. While the PNG will typically have a larger file size than the JPEG for photographic images, it does have a distinct advantage: its compression is lossless, meaning images never degrade in quality or suffer from “compression artifacting” which affects many JPEG images.
The results are crisper, brighter images that will on your pages unlike ever before.
They âre Self Optimizing! (Gamma Correction ):
Adjusting the brightness and contrast of images to look correct on a wide variety of monitors and operating systems is a common problem facing web designers. This problem is primarily related to different monitor Gamma settings.
Gamma is a method monitors use to distribute their luminance evenly across the display. Unfortunately, different operating systems (in particular the Mac and Windows) use different Gamma settings. So an image that is color-corrected for the Macintosh operating system may look too dark on the Windows operating system and vice-versa.
Utility of Macintosh in today’s corporate world
Written by admin on February 1st, 2010July 12 2006, Unlike the PC, the Mac is Apple’s proprietary technology, and except for a brief period, Apple prevented a Macintosh clone industry from developing and growing.
The Mac’s graphical ability made it a natural for graphics shops and desktop publishing. It might have been slow, but it was far more affordable than the workstations used for such purposes.
Encapsulation of Macintosh files
When we sending Apple Macintosh files, the format is compatible with existing mechanisms for distributing Macintosh files, while allowing non-Macintosh systems access to data in standardizes formats.
The Macintosh files consists two parts, called forks.
Data forks:
The actual data included in the file. The Data fork is typically the only meaningful part of
a Macintosh file on a non-Macintosh computer system.
Exactly means if you is Macintosh users, you want to send data to IBM-PC,
You only send the data fork.
Resource fork:
This is a Contains a collection of arbitrary attribute/value pairs, including program
segments, icon bitmaps, and parametric values.
If you want to know the additional information regarding Macintosh files is stored by the finder in hidden files, called “desktop database”.
MIME-based Mac files :
It contains two parts:
Header: It including the Macintosh resource fork and desktop information.
Data fork: containing the Macintosh data fork.
As a result, the Macintosh was used sporadically in the corporate world, but due to its natural bent, became popular in desktop publishing and graphics design. The Mac pioneered the use of personal computers for these applications and became the de facto standard in the graphics arts industry.
Apple ignited the personal computer revolution in the 1970s with the Apple II, and reinvented the personal computer in the 1980s with the Macintosh. Today, Apple remains committed to creating the best personal computers in the world, and its hardware and software products are widely regarded as being the most innovative in the industry.

Duck Hunting Game – Shooting Down The Ugly Duckling
Written by admin on January 29th, 2010During the 1980’s, the 1st hunting video game which was made was a game called duck hunt for the video game console, Nintendo. It needed the use of one special laser gun which allowed us to shoot ducks or ducks. You would be accompanied by one hunting dog which laughs if you miss a duck and would clap when you shoot one. Its graphics were basic and its landscape was not very much exciting, but this game was the base for the technology to move forward to the place where we’re today – having various duck hunt games to select from for all the video game consoles as well as in the personal system.
There’re various duck hunting games available for our personal computer -either you utilise an IBM-based computer or a Macintosh one. The software which is available today will be very much advanced and would give many options while it comes to the duck hunt experience. Software games which you install in your computer would give you different locations where you may hunt along with options of weapons and also various duck’s sizes. A good duck hunt game which comes in the software form would give you one online demo in their web site such that you may try the game before you get it.
Just like other hunting games, one can also get a good duck hunt game on the web and often can play it freely. While not as developed and in-depth like software versions, they’re fun nevertheless and don’t cost anything for playing other than small amount of time for registering as one member of the particular site and the site’s community.
While you’re looking for any good duck hunt game, you should take into consideration which interests you very much. Do you want to shoot many ducks or are you very much interested in lying down waiting as ducks come into the picture from hiding and will try to avoid the bullets? Maybe you would want a mix of both in the duck hunt game with multi-players capability such that you may play against your friends.
Whatever you think you need in a duck hunt game, we’re sure you’ll be able to see it. Whether it’s in the local video game’s store or any online retailer, there are many to select from and they’re readily got. So go ahead, get a duck hunt game, press that trigger, and start shooting. Oh yeah, have fun!
Macbook Pro Review
Written by admin on January 26th, 2010First impressions
The previous the MacBook Pros were very good indeed. They delivered consistently professional quality and great features. Reviewing next generation MacBook Pros is therefore something of a treat.
An initial glance at the latest models shows nothing new. This isn’t disappointing: the sturdy casings and the smart design are exactly what you want from a superior laptop. The keyboard appears tidier – the result of some minor changes – but apart from that, everything looks as impressive as it always has.
This might suggest that any internal changes are also minor. Not so. When you fire up the MacBook Pros and start putting each model through its paces, you soon realise you’re working with machines that excel expectations.
Technology
To begin with, the processors are Intel 45 nanometer Penryns. These are noticeably faster than the 65 nanometer Meroms installed in the older MacBook Pros, and easily beat the Meroms in all benchmark tests.
The standard processors for the two 15 inch MacBook Pros are 2.4GHz and 2.5GHz Intel Core 2 Duos. The 17 inch has the 2.5GHz. Allied to these are enhanced hard drives of 200GB for the 15 inch 2.4GHz, and 250GB for the 15 inch and 17 inch 2.5 GHz.
Of particular interest to the multimedia user is the doubling of the video memory on all three MacBook Pros. The 15 inch 2.4GHz has a NVIDIA GeForce 8600M GT with 256MB, and the 15 inch 2.5GHz and 17 inch 2.5GHz have the same graphics processor but with 512MB.
2GB of RAM supports the above technology across the range. The overall results are laptops that cope easily with advanced graphics and audio applications.
Hardware
Each of the three MacBook Pros comes with standard hardware, such as:
slot-loading 8x double-layer SuperDrive
iSight camera
AirPort Extreme and Bluetooth® wireless connections
stereo speakers
FireWire 400 and 800 ports
USB 2.0 ports (two on the 15 inch models; three on the 17 inch)
DVI port
Audio ports
Gigabit Ethernet port
ExpressCard/34 slot
There are also hardware “extras” that help the MacBook Pro stand out from the crowd. These include a powerful lithium-polymer battery; an ambient light sensor that illuminates the keyboard in dark conditions; and an energy-saving LED backlit screen.
These screens are mercury-free and anti-glare, and have resolutions of 1,440 x 900 pixels for the 15 inch models and 1,680 x 1,050 pixels for the 17 inch. With both you have bright, natural and pin sharp images.
Perhaps the best hardware extra of all, though, is the new MacBook Pro trackpad. This now has the multi-touch functions that have proved so popular on the iPhone. By pinching, swiping and rotating your fingers on the trackpad, you have remarkably fast and positive control over the features of the MacBook Pro’s creative software.
Multi-touch does give rise to a slight problem: the size of the trackpad may feel a little small for someone learning the appropriate gestures. That said, once you’re familiar with multi-touch, it’s not difficult to work within the trackpad’s boundaries.
Software
As with all new Macs, the MacBook Pro comes with the best operating system around, the Mac OS X v10.5 Leopard. If you’ve never used Leopard before, its proficiency will delight you. If you’re already a Mac user, you still have something to please you because the new MacBook Pros boost the speed of Leopard and the applications that run off it.
Among these applications is Apple’s latest version of the world’s fastest browser, Safari. This comes with the usual batch of updated Apple software such as Boot Camp, Mail, iChat, iTunes, DVD Player, iPhoto and iLife ’08.
Performance
Experienced MacBook Pro users can load their preferred applications on these latest models and immediately notice the improvements in speed. For example, you can set up Photoshop CS3 in approximately eight seconds on the 15 inch 2.5GHz. You’ll then go on to discover Photoshop runs 20 – 25% faster than a 2007 2.6 GHz MacBook Pro.
Compared to a 2006 MacBook Pro, the differences are even greater. Overall, you can experience speed increases of around 50% across a range of applications. This is good news for all those who want maximum performance from a laptop.
Options
With any laptops designed for professional use, it’s always worth looking at the manufacturer’s options because some people will need a buffer zone of extra speed and power for specific applications.
The configuration options of the MacBook Pro are unlikely to let you down. To give you extra power, you can request a 2.6GHz Intel Core 2 Duo processor upgrade for either the 2.5 GHz 15 inch or 17 inch models. As for RAM, you can upgrade any of the three MacBook Pros to 4GB.
On the 17 inch MacBook Pro, you might want to increase the hard drive to 300GB to provide additional room for space-stealing graphics applications. Similarly, you can ensure the perfect clarity of your images by asking for a 1,920 x 1,200 pixel screen for the same model.
Finally, if you prefer a glossy rather than anti-glare matt screen, you can request this when you place your order, as is possible with most Mac Computers .
Value
With all these upgrades packed into the same shells as the previous MacBook Pro models, you might anticipate a rise in prices. If you do, you’d be wrong. The new MacBook Pros are unquestionably better machines but the prices across the range haven’t changed. The old MacBook Pros were good value, but the latest incarnations are simply excellent for the price.
Conclusion
Want the best laptops from a great manufacturer? Look no further.
Pros
Speedier than the previous generation of MacBook Pros
Double the video memory
Smooth, multi-touch features on the trackpad
Improved battery life
Excellent configuration options
More for your money: no price increase compared to the older MacBook Pro equivalents
Cons
Trackpad may be a little small for novice users
Choosing a Laptop For College
Written by admin on January 25th, 2010These days a laptop is almost essential for a school or college student. Fortunately, there is a large range of inexpensive laptops to choose from, but which one to actually get depends on a few factors. The first question is what the student will be doing on it. If the student is going to load a graphic design program, for example, a laptop with faster processing speeds and higher memory content is a must. Apple laptops tend to be more expensive, but some prefer their ease of use.
The next step is deciding on the more technical requirements. With modern software demanding so much memory, I would suggest getting a laptop with at least 2 gigabyte (2 GB) of RAM memory. The memory capability of the hard drive ought to be around the 200 GB mark, if not higher. You don’t want to get one that is too heavy to carry around campus.
I recommend getting a laptop with at least a 15 inch screen. No doubt you will want a DVD drive and a CD burner. Some laptops have smaller, condensed keyboards, but if you are going to be doing a lot of typing then a full-size keyboard is a must.
Lenovo 3000 N 200 is a perfect laptop for businessmen, office workers, home users and for everyone. It is a perfect helper for running business matters or just for enjoying computing at home.
If you are looking for a good and inexpensive laptop, then you should pay special attention to Lenovo 3000 N 200. It is not expensive laptop. It works greatly. Thanks to Intel Core2 Duo processor this model of a laptop works quickly. Users do not have to wait too much time in order to turn on the laptop.
Watching your favorite movies on this laptop is a real pleasure. If you are working indoors or outdoors you will be amazed by the screen’s clarity.
The laptop’s keyboard and touchpad are very comfortable for usage. Typing on this keyboard is a real pleasure. In general, the laptop works very quietly.
It is a very portable laptop and it is possible to take it anywhere you go.

Apple IPhone 3G S Mobile Phone Review – Speedier Performance With a Longer Battery Life
Written by admin on January 13th, 2010Soon to be a part of our lives – the Apple iPhone 3G S holds the promise of speedier performance, and – we hold our breath – a longer battery life. The previous edition – the Apple iPhone 3G, while a fantastically sophisticated iPhone offering, was a little short of the battery oomph necessary to keep it going all day – barely a day’s use, if you were lucky.
With “speed” as the new watch-word, it will be nice to see if the 3G S comes up to scratch. As always in the IT and phone world, software features run way ahead of the physical capabilities of the hardware itself, and that is what Apple is trying to address with their new upgrade.
We still see the same features as the older 3G version offered – Cut, Copy and Paste, MMS and a landscape keyboard which is very handy and much easier to use than the vertical type – but then Apple has always been into ergonomics, right from the day they brought out their first personal computer.
Then, too, the new 3G S has Voice Memos and Spotlight Search, and a camera – and there the paths of the two iPhone designs part ways:
Whereas the old version 3G had a 2-Megapixel camera with no auto-focus, the 3G S now sports a 3-Megapixel camera, with autofocus capability. Let’s hope that it’s fast – there is nothing worse than trying to take an action shot of your loved ones and then find the moment has disappeared into the wild blue due to a slow autofocus on your phone’s camera.
Then there comes the Improved Performance – a new processor which supports 7.2Mbps HSDPA for speedier Web browsing. This should make loading faster, and with a storage capacity of either 16GB or 32GB, if the 3G S meets expectations we are in for pleasant surfing. With updated 3-D graphics facilities – users are in for a gaming experience we have only dreamed about – the 3G S is up to twice as fast as the 3G.
If you are inclined to follow the Highway Code, the Apple iPhone 3G S provides total hands-free operation . Voice Control allows you to verbally ask for a call to a name on your contact list, or select music on your iPhone, recognising composer and song name.
In line with the voice control, the Apple 3G S offers features to improve accessibility to those who are visually impaired. This includes a VoiceOver screen reader, a zoom feature, and white on black display option. For those with hearing impairment there is the Mono Audio facility.
With a built in digital compass, you will always know where you are headed. This could be particularly useful in situations such as hill walking, especially for the direction-confused map-reader, as the 3G S will rotate the map to suit the direction in which you are facing.
With Tethered Internet capability (share with Mac Notebook or PC laptop 4), video and voice recording and plenty of apps in the Apps Store to choose from, the Apple iPhone 3G S seems to offer a good package for its rather pricy tag – costing a hefty £275 (average price), time will tell whether users of the 3G will feel the upgrade is worth while.
