USB 3.0 "SuperSpeed USB"

                        USB 3.0 promises to increase performance by a factor of 10, pushing the theoretical maximum throughput of the connector all the way up to 4.8 gigabits per second. USB 3.0 can read and write data simultaneously. This is achieved by adding two new lanes dedicated to transmit SuperSpeed data and another pair for receiving it.

       USB 3.0 cable contains nine wires (four more than a USB 2.0 cable); eight carry data and one is used as a ground. There will be a big difference in performance however, USB 2.0 is like a single-lane country road that needs to handle the morning-commute traffic in and out. There are jams and slowdowns when too much data is going back and forth. With nine wires available, USB 3.0 has an additional two lanes of traffic in each direction to smooth the flow between the computer and the device.

       USB 3.0 has also increased the amount of current that a downstream USB Device can draw from a PC.This limit is raised from USB 2.0's 500mA to USB 3.0’s 900mA, which translates into an 80% increase in available power. it allows mobile handhelds to charge their batteries faster.  For example, to fully charge a drained 1400mAh battery with an assumed 90% efficiency would take over 3 hours with a USB 2.0 Host,  but only 1.5 hour with USB 3.0.

         The MSP program is an educational and promotional program to sponsor undergraduate and postgraduate students majoring in disciplines related to technology, typically computer science, computer information systems, and information technology. MSP program aims to enhance students' employability and increase students' awareness of Microsoft technologies.
        
        The key focus in the Microsoft Student Partners program is to create a better chances for employment for the people in the program. Also, it's partially in place to help students and teachers better understand the possibilities of new technology.
     
       To apply to the program, you need to send a free form application to either a local Microsoft Student Partner or Microsoft's ADE (Academic Developer Evangelist).
       After graduation, student partners continue as alumni members, being the link with student partners and working life. Usually, student partners get hired into Microsoft's partner companies quite easily so not only is it a great way to get involved with interesting technology, but it's a great way to start your career path.

Hey all
you know that we can’t create a folder named CON, NUL, COM1, COM2, COM3, LPT1, LPT2, LPT3,COM1 to COM9 and LPT1 to LPT9....
in any of the windows operating system.
try with this.
one method to create the folders with these reserverd system names.
1) go to run dialog.
2) type cmd/command (command prompt gets opened)
3) go to root directory like C:\ or D:\ etc
4) type md\\.\\c:\\con ....(here is done)
5) check the folder on the respected drive.

Thunderbolt Technology

Thunderbolt technology is a new breakthrough technology that work like the USB port, but
allows you to daisy chain multiple devices (up to 6 devices) together.


The current copper-based generation of Thunderbolt boasts 10Gbps data transfer speeds between computers and devices that is, twice the speed of current USB 3.0 throughput. Future iterations of the specification are expected to move from copper wire to a fiber-optic connection, which Intel has said could one day allow for  throughput rates up to 100Gbps .
        Thunderbolt can transmit both raw data and audio-video information simultaneously, the technology  is also bidirectional, According to Intel, each port will be able to send and receive data simultaneously, at full 10Gbps bandwidth in both directions.
To illustrate how fast it is:
  •     it take a mere 30 seconds to transfer a full-length HD movies (around 1.5 – 2.5 GB in size),

  •     a mere 10 minutes to transfer a year of continuous MP3 playback.
