Pen Drive – How is it?

A pen drive is a small portable data storage that can be plugged into the USB port of any compatible computer. A pen drive is composed of a non-volatile memory, clock generator, and a light controller. Some pen drives offer VoIP services, mp3 player, fingerprint reader, the password protection and other functions. The history of the art of a pen drive began with a CMOS chip. This low power, high density circuits marked the beginning of digital integrated circuits. CMOS circuits are comparable to today’s BIOS and have been responsible for configuring the base system computer. There was however a major problem with the CMOS chip. A constant current source is necessary to maintain the data. Then there was the advent of the EEPROM chip. This chip has overcome the disadvantage of the CMOS chip, but they had a limited lifespan. The materials used inside the chip was on a growing number of write operations. This paved the way for the entry of pen drives. Pen drives are flash memory and are thus also called flash drives. Flash memory was invented by Intel in 1988 and they provided faster access to data. Flash memory can be used by any application that does not require electrical power. M-Systems (SanDisk) were the first to work on this concept in 1998. Initially, SanDisk has worked with IBM to produce the pen drive, but later he bought all the rights and produces advanced version of this pen drive. Flash memory was invented by Dr. Fujio Masuoka Toshiba in 1980. Flash memory can be both NOR and NAND type. NOR flash memory chip-type was introduced on the market by Intel in 1988. NOR-based flash memory soon gave way to the NAND flash memory more affordable. 1989 saw the advent of NAND flash memory by Toshiba. In comparison, NAND quickly erase and write times, greater storage capacities and lower costs. A pen drive uses NAND flash memory chip. NAND chip with a storage capacity of 1GB was introduced by SanDisk and Toshiba in 2005. Samsung followed with a 2GB version followed by 4 GB and 8 GB in the next year. Today, we can get 128 GB of memory pen on the market! The technology to be tested in pen drives is the U3 platform. The security constraint was largely overcome by this technology. SanDisk has developed this platform. The pen drive can be forged, and integrated with passwords for security measures. U3 platform USB drives using ICQ instant messaging software. This software allows the owner of pen drive e-mail and Google search with ease. LaunchPad interface is activated inside the pen drive using the U3 platform. Many different types of software can be loaded into the pen drive using the interface and the different employment can be achieved. These include the management of files, passwords, anti-virus, file synchronization and call its software. The U3 platform USB has the ability to customize any PC. He has the ability to customize your desktop, game programs, web browsers, e-mail, instant messaging and personal preferences. However, the issue of security and confidentiality of data are the most important considerations in the U3 USB key using. His only password protect the software does not breach security. Pen drives have therefore made a mark for themselves in our lives and are now irreplaceable. Whether data management, storage, transfer or security; pen drives can not do without. Their portability and multi-use make it the ideal companion for any computer buff. However, care must be taken to keep it entirely free of the virus so that it does not become a scourge of a bargain.
