Explanation:
Universal Serial Bus (USB) is a high speed bus standard developed by Compaq, IBM, DEC, Intel,
Microsoft, NEC, and Northern Telecom. It provides the Plug and Play capability of Windows to
external hardware devices. USB supports hot plugging, which means that a USB device can be
installed or removed while the computer is running. A single USB port can be used to connect up to
127 peripheral devices, such as CD-ROM drives, tape drives, keyboards, scanners etc. USB 1.1 has a
maximum data transfer rate of 12 Mbps, whereas USB 2.0 has a maximum data transfer rate of 480
Mbps. USB 2.0 is fully backward compatible with USB 1.1.
Answer option D is incorrect. Software drivers are required for USB devices. It is possible, though,
that the drivers for your USB devices are already available on the computer. In this case, you do not
need to provide a device driver separately.
Answer option B is incorrect. It is not required to restart the computer to install USB devices.
