What are the components of complex computer system?
Q. The vendor delivered product which has only executable code and very small user's manual. No source code, no programming documentation. He reciewed over 2 mln dollars for that. The contract did not list what components he should deliver. Can it be safly assumed that any complex system have to have all the components. Are there any industry standarts?

A. Well. Your question is not really complete. Was it hardware that was delivered such as a mainframe, or switch, or router? or was it SOFTWARE, code written to do something specific on a computer, something written to work on a PC, or a mainframe, or a Microsoft network server, or netware server, etc. etc. I am going to assume, it was only software, and was written to run in Windows on a network of some type, as this is the most common situation. I have over 30 years of experience as a Network engineer. I have been a programmer / developer, hardware engineer, service technician, network administrator, project manager, designer, etc. etc. The Short answer is hiring developers to come up with something is a ripoff, designed to make them… [cont.]

What are the most important components of computer if you are building one?
Q. I know CPU and RAM are very important, as well as the video card. But are fans and cooling components important too? Can anyone recommend me a good cooling units and other good components?

A. If you are building your own computer, I think it's quite important to select all the components carefully... If you go for cheap stuff it will either hold the whole machine back or fail earlier than the rest. Having said that, the key things are the Power Supply, CPU, Motherboard and RAM - these things are critical. After that comes the Graphics card (this is more critical if gaming), and drives (hard disks and CD/DVD)... A well ventilated case and good cooling fans is a must, although medern CPUs do run quite cool if you don't overclock them. Thermaltake generally make good case cooling solutions (I think) and for the CPU cooler, look here:

What are the components or elements that makes the ink of a highlighter?
Q. the highlighters are the one you use to highlight the important details on your books. I noticed that high lighters' ink doesnt fade or wash off like ordinary pen ink in water... just wondering if I can invent a pen someday using the same components of a highlighter and change the color and turn it to black, blue or red. So that in situations when you accidentally soak your notebook with important details, it will never fade or wash off.

This is a truly fun place and you can find things from the 40's forward but not too forward. You do know that was a story (well mostly) right . Don't forget the vacuum tubes you will need lots of vacuum tubes, big ones, very very big ones. Get maybe 5 Klystron tubes, you know just for fun.

Q. Supposing a system is made up of a number of components, any of which may fail. If any component fails, the system fails. Mathematically expressed, how does the number of components affect the probability of failure? Or how does it affect the mean time between failures?

A. Operating probability = 1 - failure probability Lets denote that as r = 1 - p Operating probability of a system = operating prob of component A * operating prob of comp B * ... So in a system of n components, the system's operating probability R is given as: R = (1-p)^n where " ^n " means raised to the nth power Thus failure rate of the system, = 1 - R = 1 - (1-p)^n and MTBF = 1 / = 1 / [ 1 - (1-p)^n ]

Factors like the thickness of the pipes that go into deep thermal wells are dependant on the corrosion potential of the source. Thin pipes transfer quicker with higher efficiency. Thick last longer. A motor that transfers fluid down a few hundred feet into a water well will be rated differently from a pump that has to go down a thousand feeet.

A. so, v is 20 at 40 degrees the horizontal speed=20cos40 the vertical speed=20sin40 so, after 1.1 seconds, it would move 20cos40 x1.1 meters horizontally. just repeat this for 1.8 and 5 seconds for vertical movement, you know the initial speed (20sin40). you know acceleration (-9.8), you know time (1.1), and you need to find distance. So use the kinematic equation with those 4 variables to calculate it d=vt+1/2 at^2 sub it all in and calculate d. repeat for t=1.8 and 5

Q. A stone is catapulted at time t = 0, with an initial velocity of magnitude 20.0 m.s and at an agnel of 40.0degrees above the horizontal. What are the magnitudes of the (a) horizontal and (b) vertical components of its displacement from the catapult site at t = 1.10 seconds ? Repeat for the (c) horizontal and (d) vertical components at t = 1.80 seconds, and for the (e) horizontal and (f) vertical components at t = 5.00 seconds.

How would I go about hooking up car stereo components to a home stereo?
Q. I have two-1000watt amps, two-15 inch subwoofers and a multi-input equalizer that I'd like to keep for my home stereo system. How would I go about wiring all the components to work off of a AC input or how would I get a DC input working at home without it having to be a car battery? The wiring for a typical car installation I'm familiar with but how would I wire this for power without the car or the battery's current?

A. NO you just don't do this. Bad sound, high cost, and the stupid factor all come to mind.
