The Universal Serial Bus (USB) is a new industry-wide standard that will eventually replace the hassle of connecting parallel and serial devices to your computer. With USB, you don't need to worry about selecting the correct serial or parallel port, installing expansion cards, configuring the myriad of dip switches, IRQ (interrupt) settings, DMA (Direct Memory Access) channels, I/O (Input/Output) addresses, or the getting the correct settings for the device's software drivers. USB is Plug & Play with a twist, you never have to turn off the computer to connect or disconnect a device. You have virtually unlimited expansion capabilities without ever having to remove the cover off the computer. USB has an industry standard, one-size-fits-all connector that allows you to install and remove devices without opening the computer. Since this connector is hot swappable, you do not have to turn off the computer.
