•Multiplexing means to break high-speed physical communication circuit into several lower-speed logical circuits so that many different devices can simultaneously use it.
Multiplexing is a mechanism that allows multiple devices to share a single high-capacity link.
The device which facilitates multiplexing is a multiplexer (MUX), which bundles the signals from the source nodes into the shared medium.
On the other end, a demultiplexer (DEMUX), would split the bundled signal back to its intended nodes.
What is suitable operating system for scientific calculations and multimedia?
Totally different things .... Multimedia : Microsoft Windows 2000 or XP Professional. Windows XP Home is also okay but has lots of bugs than XP Pro. To me Microsoft 2000 Professional is the BEST Operating System Microsoft has ever created ... Scientific Calculations : Depends on what kinds of software applications or tools you run for your scientific calculations. go for Sun Solaris UNIX or Linux Flavours. I Mean Gentoo Linux and Red Hat Linux are the best Linux flavors. I u want both things then Best approach is to have Windows 2000 Professional with SP4 installed as well as either Red Hat Linux (Fedora Core) or Gentoo Linux installed on the same hard-drive with a DUAL Boot mode. I have DUAL Bool with Windows 2000 Pro as well as Fedora Core which is Red Hat Linux version 10.
How do you replace the lamp on a Sanyo pro xtrax multimedia projector?
Sanyo manuals normally include instructions on lamp replacement. Without a model number, it is not possible to provide a detailed instruction and it is important that the manual's instructions are followed precisely. In particular, heed the warnings regarding safety. Not only are the lamps expensive, they can also be hazardous if they are not handled correctly.
If the manual isn't available, almost all projector manuals can be downloaded from the Sanyo web site. Once you have found the Sanyo site for your own country, go to the support or download section making sure you have the full model number of the projector ready to enter.
If you are unsure about doing it, your local audio visual dealer will be more than happy to change the lamp for you.
You can buy tester's that will do it for you. Try ebay.

What is the differences between parallel connection and serial connection in water pumps?
Parallel and series connections differ in their connection to the feed line. In parallel, each pump is fed directly from the feed line. This means that the water going into each of the pumps is at exactly the same state and the pumps may be analyzed individually. In series, the water is fed through one pump, then the exit line from that pump leads to inlet of the next and so on.
What determines the setup for a specific application is the desired property of water at the exit. Two pumps in parallel connection can produce a higher flow rate. Two pumps in serial connection can produce a higher pressure.
