    Re: how does a usb works?

    Hi..
    USB flash memory uses "solid state" technology to store data. While most built-in computer hard drives are magnetized and subject to data loss when exposed to magnetic fields, solid state storage units write data electronically to the media. Each drive is sectioned off into tiny, electrically charged "blocks." When you make changes to the files on the drive, the data is electrically stored in these blocks and remains even if the USB drive does not have power. It's easiest to think of flash memory like a chalk board. The data you place on it will remain, indefinitely, until you erase it. Like erasing and changing a single word on a chalk board, deleting or altering one file will not affect the rest of the drive..😀

    ..Few points give you better idea of usb
    1:-It provides serial data transfer...ie 1 bit at a time...hence quite fast...
    2:-It provides min transfer rate of 1.5 Mbps
    3:-It uses NRZ-I encoding technique to transfer data..hence no requirement of proper synchronisation...
    4:-It is hot pluggable and swappable..ie it allows removal of usb peripheral devices while it is powered
