Microsoft is developing a new technology dubbed Vi-Fi, which means Wi-Fi in vehicles.

This system will enable users to use Internet while on the move, and will cost less than existing cellular broadband systems.

The software giant is working on this technology in collaboration with the University of Massachusetts and the University of Washington.

This new technology promises to offer a steady signal unlike Wi-Fi networks, where each signal station (base station) only broadcasts so far, so users have to hop between stations. During these transitions, known as “hard handoffs”, the signal strength typically drops, writes DailyTech.

Today’s Wi-Fi handoff protocols are incredibly fragile in outdoor environments and mobile environments artificially limited to talking to only one access point, or only one base station at a time, even though there may be other base stations in the area.

Therefore, Vi-Fi is being designed to send and receive signals from more than one base station and the strongest strength gets designated as anchor, while others are also used as auxiliary systems.

Researchers with Microsoft, University of Washington and Massachusettsbelieve they are the first to suggest such a solution, which may finally make vehicle Wi-Fi workable. They have already tested the system on Microsoft’s campus in Washington and further planning to conduct the test on a bigger scale in the area surrounding the campus.

1. Change text size while browsing

While browsing, you may come across web pages that use too small or too large a text size to be comfortably readable. To change the size of the text, click View and then Text Size. Click the text size that you’d like from the options available.

2. Open links in new Internet Explorer windows

8. Create Desktop shortcuts to your Favorite websites

If you have websites in your Favorites folder that you like to visit very frequently, you can create shortcuts to them on your Desktop. Open Internet Explorer and shrink its size using the square icon on the top-right corner, so that you can see your Desktop. Click Favorites and go to the saved link for your website. Drag the icon for this website and drop it to your Desktop. Your shortcut is ready.

9. Rename or delete Favorites quickly

You can organize the links stored in your Favorites list without going to Organize Favorites. Open Internet Explorer and click Favorites. Right-click the link that you want to rename or delete; and choose the desired option from the menu.

Laptops are some of the most widely used gadgets of the 21st century. Their appearance and development during the last 3 decades made our everyday life easier. Laptops are used almost everywhere: at homes and offices, hotels and means of transport. According to the amount of space, people buy laptops of various sizes. Thus there are several categories of notebook computers. Every design and size corresponds to the user’s specific needs.

There are five categories of laptops. Every category has its advantages and disadvantages.

Ultraportables (weight: under 4 pounds)

It represents a very compact notebook that one can carry in a small bag. Computers from this category have low demands, which is why they are quite small in size. An ultraportable laptop has a futuristic design, a light weight and it represents a perfect choice for a traveler.

However, ultraportables are meant mainly for less space rather than high performance. They are not meant for high-demand business applications and games that require intense graphics. The smaller is the laptop the less life its battery will have. The screen is small and a high resolution can be hard on one’s eyes.

Because of its small size the keyboard has smaller buttons which is not very comfortable for those with large fingers. Light ultraportbles do not include CD and DVD drives. The latter serve as external accessories. However these drives can be found on heavier laptops from the ultraportable category.

Standard Laptops (weight: 6 to 8 pounds)

Almost every standard laptop includes DVD/CD-RW drives. This category is very popular and the prices are more affordable than notebooks from other categories. The average battery life is about 3 hours but there are high-capacity versions that are able to work for 5 hours. The standard laptops are not as compact as ultraportables. The user will also have to carry additional peripherals in order to read various media card formats. The same concerns the connection to other devices.

Thin and Light (weight: 4 to 6 pounds)

Laptops from this category have powerful processors. Most thin and light notebooks have 14 inch displays, which allow viewing everything from Word and Excel files to various internet pages. The battery is able to live for more than 3 hours. There are a lot of thin and light laptops that have the ability of swapping out an optical drive. Notebooks from this category are able to transfer the information wirelessly (for example through Bluetooth) without a significant drain of battery life.

There are also several ports available: USB 2.0 and parallel. Some thin and light laptops encounter even serial ports. This category is popular for the ability of connecting a video camera.

Desktop Replacements (weight: 8 pound and up)

This category includes laptops with wide screens, sharp displays as well as great graphical performances. Desktop replacements are perfect for gaming and business performance. This is due to the fast CPU and improved video chips. These laptops have improved audio systems and some of them also include subwoofers.

One of the disadvantages of desktop replacements is their size. For example they will not fit under an airplane seat. Another negative aspect is their battery life.

This category includes some of the most expensive computers on the market today. The price varies from 1,500 to 4,000 US dollars.

Tablet PC (weight: 2 to 4 pounds)

The main advantage of the table PC is their touch screen. This feature is very useful for some specific professions like, for example, medicine. These computers are also able to convert hand writing into editable text. The user can view tablets in two modes: regular and pivoted on end. Thus one can switch the table screen to a portrait mode.

Laptops from this category have the longest battery life among other categories. The disadvantage of tablet PC is their slow processor and little RAM. These notebooks are not meant for business or gaming performances. The CD and DVD drives are very often add-ons connected as external sources.

According to a laptop’s performance one can choose a notebook suitable enough for his or her lifestyle. The market of laptops continues its expansion adding new additional features satisfying even more of customers’ needs.

As you probably know, your hard drive is the most important component in your computer because it houses all your data. Unfortunately it is the most likely device to fail. While virtually all modern hard drives have S.M.A.R.T. technology built in to detect failures, one important factor you can monitor is your hard drive temperature with HDD Temperature.

HDD Temperature is a free program which, simply put, monitors and warns you when temperatures get to high on your hard drive. You can customize the temperature warning level as well as how the system responds to a tripped warning.

The free version is limited to a single hard drive, so if you have multiple hard drives in your system, or you want to monitor a server, then the pro version might be a better fit.

The new USB 3.0 standard (specification) will be released in the first half of 2008, Intel has revealed at its Developer Forum.

The present day USB 2.0 delivers a transfer speed of upto 480 Mbps, whereas USB 3.0 promises 10 times of this speed taking the transfer rate to 4.8 Gbps.
Moreover, It will be backwards-compatible with USB 2.0, which is backwards-compatible with the first USB 1.1 definition.

Intel stated that the USB 3.0 specification would be optimized for low power and improved protocol efficiency. The USB 3.0 ports and cabling will be designed with both copper and optical cable capabilities, meaning even higher speeds will be possible in the future. “USB 3.0 is the next logical step for the PC’s most popular wired connectivity,” said Jeff Ravencraft, technology strategist with Intel and president of the USB Implementers Forum (USB-IF). “The digital era requires high-speed performance and reliable connectivity to move the enormous amounts of digital content now present in everyday life. USB 3.0 will meet this challenge while maintaining the ease-of-use experience that users have come to love and expect from any USB technology.”

He further said : “If the USB 3.0 Promoter’s group meets its objective of spec completion in the first half of 2008, then we should see the first silicon solutions on the market in 2009, followed by end products in late 2009 or early 2010.”
