2020年9月30日 · UNIVAC, which stood for Universal Automatic Computer, was developed by J. Presper Eckert and John Mauchly, makers of ENIAC, the first general-purpose electronic digital computer. These giant computers, which used thousands of vacuum tubes for computation, were the forerunners of today’s digital computers.

2008年2月25日 · univac said: Have a good look at the circuit the triangular arrangement is probably throwing you off. If you put a voltage source between b (positive terminal) and c (negative terminal) the c node becomes your circuit ground.

2010年9月25日 · We are currently learning about solenoids in my physics class, and am very confused about where this potential drop comes from across a solenoid. I understand that an opposing electric field is created when a switch is first opened because of Faradays Law and the fact that the magnetic flux...

2008年2月22日 · Think about what you're looking for, you want to know the voltage of the battery. If the battery were, say, 5 V, that means you could say the top part of that circuit, all the lines immediately connected to the + terminal of the battery, were at 5 volts, whereas all the lines immediately connected to the negative terminal were at ground

2015年9月22日 · That’s really a stretch, IMO. There is a huge difference between a Univac-era computer cranking out the decimal digits of ##pi##, as compared to a computer tabulating all possible ways that a map could be colored using four colors. Log in to Reply
