Only Philips goes to theselengths to deliver this exacting level of color accuracy and display quality in every new monitor.UUSB or Universal Serial BusA smart plug for PC peripherals. USB automatically determines resources (like driver software andbus bandwidth) required by peripherals. USB makes necessary resources available without userintervention.USB eliminates "case anxiety" -- the fear of removing the computer case to install add-onperipherals. USB also eliminates adjustment of complicated IRQ settings when installingnew peripherals.USB does away with "port gridlock." 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 formultimedia computers arrive on the market every day. With USB, up to 127 devices can runsimultaneously on a computer.USB permits "hot plug-in." There's no need to shut down, plug in, reboot and run set-up toinstall 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!HubA 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. The Figure shows a typical hub.Hubs serve to simplify USB connectivity from the user's perspective providing low cost andcomplexity.
