A pen drive is often a smaller portable details storage device that can be plugged in for the USB port of any compatible computer. A pen drive consists of a non-volatile memory, clock-generator, LED indicator and also a controller. Some pen drives provide VoIP, mp3 player, fingerprint sensor, password protection along with other functions.
The technological history of the pen drive began having a CMOS circuit. This low power, high density circuits marked the starting of digital integrated circuits. CMOS circuits are comparable on the BIOS circuits of today and have been responsible to your straightforward system settings of the computer. There was nonetheless a major dilemma with this CMOS circuit. A constant power source was required to preserve the data.
Then there was the advent of the EEPROM chip. This chip overcame the disadvantage of the CMOS chip but they had a limited lifetime. The materials in the chip wore out with increasing amount of write operations.
This paved the way for your entry of pen drives. Pen drives have flash memory and so are also referred to as flash drives. Flash memory was originally invented by Intel in 1988 and they provided a faster access to data. Flash memory could be applied by any electrical software package which did not need electrical current. M-Systems (SanDisk) had been the very first to jobs on this idea in 1998. Initially, SanDisk collaborated with IBM in making the pen drive, but later on it bought all of the rights and made advanced versions of this pen drive.
Flash memory was invented by Dr. Fujio Masuoka for Toshiba in 1980. Flash memory can be both NOR and NAND types. NOR-type flash chip was brought to the industry by Intel in 1988. NOR-based flash memory soon gave way to the a lot more affordable NAND-type flash memory. 1989 saw the advent of NAND flash via Toshiba. Comparatively, NAND had faster erase and write times, greater storage capacities and lower costs.
A pen drive uses NAND flash memory chip. NAND chip owning storage capacity of A single GB was introduced by SanDisk and Toshiba in 2005. Samsung followed suit having a Two GB version followed by 4GB and 8 GB from the following year. Today we can get 128 GB memory pen drive during the market!
The latest technology being tested in pen drives stands out as the U3 platform. The security constraint has been greatly overcome by this technology. SanDisk has designed this platform. The pen drive can also be created tamper-proof and integrated with passwords for security measures. U3 platform in pen drives utilizes ICQ instant messaging software. This software helps the pen drive owner to email and Google search with ease.
The LaunchPad interface is enabled in the pen drive using U3 platform. Several different varieties of software package is also loaded within the pen drive using this interface and various jobs can also be performed. These include photo management, password protection, anti-virus, file synchronization and call-making software.
The U3 platform in pen drives has the capacity to personalize any PC. It has the potential to customize desktop, games web browsers, e-mail programs, instant messaging and own preferences. However, file security and info privacy are probably the most critical considerations in pen drives using U3. Its distinct password-protect software doesn't enable any breach of security.
Pen drives have thus produced a mark for themselves in our lives and are now irreplaceable. Be it facts management, storage, transfer or security; pen drives can't be done without. Their portability and multi-utility make them the ideal companion for any personal computer buff. However, care ought to be taken to retain it entirely virus-free so that it doesn't adjust into a bane from a boon.
