[. . . ] Safety precautions and maintenance WARNING: Use of controls, adjustments, or procedures other than those specified in this documentation may result in exposure to shock, electrical hazards, and/or mechanical hazards. Read and follow these instructions when connecting and using your computer monitor: q Disconnect the monitor from the power supply if the monitor is not to be used for an extended period of time. Do not attempt to remove the back cover, as you will be exposed to a shock hazard. The back cover should only be removed by qualified service personnel. [. . . ] Composite sync: Horizontal and vertical sync pulses mixed into a single signal train. SOG: Horizontal and vertical sync pulses mixed, then combined with the green color signal. With TTL driving, the red, green and blue signals can only be switched on or off or provided with an intensity signal. USB makes necessary resources available without user intervention. q USB eliminates "case angst" -- the fear of removing the computer case to install add-on peripherals. And USB also eliminates adjustment of complicated IRQ settings when installing new peripherals. " Without USB, PCs are normally limited to one printer, two Com port devices (usually a mouse and modem), one Enhanced Parallel Port add-on (scanner or video camera, for example) and a joystick. More and more peripherals for multimedia computers arrive on the market every day. With USB, up to 127 devices can run simultaneously on a computer. " There's no need to shut down, plug in, reboot and run set-up to install peripherals. And no need to go through the reverse process to unplug a device. In short, USB transforms today's "Plug-and-Pray" into true Plug-and-Play! hub A Universal Serial Bus device that provides additional connections to the Universal Serial Bus. Hubs are a key element in the plug-and-play architecture of USB. Hubs serve to simplify USB connectivity from the user's perspective and provide robustness at low cost and complexity. Each hub converts a single attachment point into multiple attachment points. Each of the other downstream ports of a hub allows connection to another hub or function. Hubs can detect, attach and detach at each downstream port and enable the distribution of power to downstream devices. Each downstream port can be individually enabled and configured at either full or low speed. The hub isolates low speed ports from full speed At the lowest level, device may refer to a single hardware component, as in a memory device. At a higher level, it may refer to a collection of hardware components that perform a particular function, such as a Universal Serial Bus interface device. At an even higher level, device may refer to the function performed by an entity attached to the Universal Serial Bus; for example, a data/FAX modem device.
