How USB Works!

"Pen drive" is another name used to describe a certain type of universal serial bus (USB) flash drive. Pen drives are NAND-type flash memory cards that can be plugged into a computer's USB port. The term "Pen" refers to its size. This type of flash drive is so small that it can fit into the palm of your hand or hang on a lanyard. Also, it is often flat and rectangular, similar to the shape of a highlighter pen. Pen drives are used to store data. These flash drives vary in storage capacity (64 MB to 32 GB) and are removable and rewritable. Techies often purchase pen drives as replacements or backups for CD-R's or floppy disks. However, the average Joe unwittingly purchases pen drives in the form of iPods and MP3 players. Yes, iPods and MP3 players are the most popular form of pen drives these days. And, the key to their success lies within their circuit boards. When a pen drive is connected to a USB port, it activates. Ot

Energy From Window!

Did you ever think about producing energy from the window of your home to meet up with the energy needs? An Israeli company named Pythagoras Solar invented the World’s first transparent Photovoltaic glass unit (PVGU) which will produce energy from sunlight directly. Pythagoras Solar beat out nearly 5000 entrants to win this year’s $100,000 GE Ecomagination Challenge, which recognizes the most promising green energy building innovations, for its unique solar window. According to the CEO of Pythagoras Solar, the window will produce benefits such as power generation and reducing the building energy needs, while allowing light in. The technology is its optical design uses direct light to generate energy, while optimising daylight inside the building. Photovoltaic Glass Units (PVGUs), are compatible with standard glazing systems, combine energy efficiency, high density solar power generation and transparency. PVGUs employ a prism system that steers most of the so-called direct

Intel-Ivy Bridge (3rd Generation Processors)

After the i-series processors 2nd generation processors Intel   presented the 3rd generation Intel Core processor, code named 'Ivy Bridge', that would power 2012 Ultrabook devices. Intel said phase two of the multi-year, industry-wide Ultrabook vision would begin with the launch of 'Ivy Bridge' next year. Ivy Bridge, Intel’s 22nm successor to the currently dominant Sandy Bridge generation of processors, has been the subject of most of the talk at IDF this past week. And yet, one of its highlight features managed to go by almost unnoticed: the graphics processor integrated inside the Ivy Bridge chip will be able to decode video at a resolution of up to 4,096 x 4,096. That’s north of 16 megapixels at a time, but don’t get carried away with visions of our supreme HD future just yet.  Sandy Bridge, Nehalem's successor, is the code name for a processor microarchitecture developed by Intel at Intel Israel Development Center   beginning in 2005 targeting the 32 nm proces

Apple Inc. Released OS X-Lion

The Software and hardware giant Apple released the latest version of iOS, X Lion. Mac OS X Lion   (version 10.7) is the eighth and current major release of Mac OS X, Apple's desktop and server operating system for Macintosh computers. Features: Address Book  now uses an iPad-like user interface . AirDrop  – Lion-to-Lion direct file sharing via Wi-Fi Direct. No wireless access point required. Address space layout randomization  – Address space layout randomization (ASLR), a security technique that puts important data in unpredictable locations, making it harder to target known weaknesses, is available for 32-bit applications, and "has been improved for all applications", in Lion. Apple Push Notification Service  – Send over-the-air alerts, such as news updates or social networking status changes, using Apple's Push Notification service to applications that support APNS. APNS allows Mac OS X Lion and iOS clients to receive push changes to items such a
