Silicon Chips
Three steps to making silicon chips:• Converting sand to silicon• Creating a cylindrical crystal• Slicing the crystal into wafers

USB CordsUniversal serial bus, a connection technology for attaching peripheral devices to a computer, providing fast data exchange.
Just about any computer that you buy today comes with one or more Universal
Serial Bus connectors. These USB connectors let you attach mice, printers and other accessories to your computer quickly and easily. The operating system
supports USB as well, so the installation of the device drivers is quick and easy, too. Compared to other ways of connecting
devices to your computer (including parallel ports, serial ports and special
cards that you install inside the computer's case), USB devices are
incredibly simple.
The goal of USB is to end all of these headaches. The
Universal Serial Bus gives you a single, standardized, easy-to-use way to connect up to 127 devices to a computer.
Jump DrivesJumpDrive™ is a Lexar
brand name for a Universal Serial Bus (USB) storage device, also called
a USB flash drive (UFD).
Also know as: memory stick, thumb drive, or
flash drive.
The JumpDrive or UFD is a small, portable device about the size of a BIC
lighter or package of gum. The body is an encased
circuit board with a memory chip, with one end featuring
an integrated USB connector. This connector
can slide into a USB port on nearly any computer,
making the JumpDrive ideal for quickly transferring data
or programs.
