voltages must be on before data information can be transmitted in digital computers
and not so when using the internet, because the message is transmitted at the slightest glimpse of power source. does not need proper voltage to carry out transmission

Why are transmission voltages in multiples of 11?
Transmission voltages are in multiples of 11 to allow for 10% transmission line losses. Therefore, to obtain 100% efficiency, voltages in multiples of 11 are transmitted.
Could the first computers hold a lot of energy?
The first computers could electrocute you because of high supply voltages needed by the tubes.
Which type of computer is used in petrol pumps?
analog computers, which use the fluctuations of voltages to directly display the result.
What method is used with binary value 10110 is transmitted and the polar signal contains seven transitions between negative and positive voltages?
Differential Manchester
How do robots commitcate?
Robots are run by computers which communicate with numbers, represented by binary combinations of high and low voltages of electricity.
What are the Components of second generation of computers?
Discrete components. Most components were the same as in first generation computers, but vacuum tubes were replaced with transistors. Operating voltages were correspondingly reduced and circuits sped up as a result.
Why are none of the headlights are working on lowbeam but when switched to highbeam all for of them come on for a 1988 brougham?
I have to suggest the light switch is bad. A simple voltmeter or test light may help you test voltages. I have to suggest the light switch is bad. A simple voltmeter or test light may help you test voltages.
What basic law of electromagnetism explain how an antenna picks up a radio signal?
Faraday's law of electromagnetic induction explains how an antenna picks up a radio signal. When a varying magnetic field from the radio signal interacts with the antenna, it induces an electric current in the antenna through electromagnetic induction. This current can then be amplified and decoded to produce the audio signal heard on the radio.
Suppose that the binary value 10110 is transmitted and the polar signal contains seven transitions between negative and positive voltages what method of polar encoding was used in this case?
Differential Manchester
What three DC voltages do computers use?
There is no fixed number of DC voltages that computers use. Computers have used as few as one DC voltage to many of dozens of different DC voltages, depending on the design of the logic circuit electronics they use. From the middle 1960s (with the introduction of TI's 7400 TTL integrated circuits) through the present +5 VDC became a nearly universal voltage in computers. From the early 1970s (with the introduction of NMOS microprocessors, e.g. the Intel 8080) the +12 VDC and -12 VDC became common in microcomputers. In the 1990s (with the introduction of low power energy efficient microprocessors) +3.2 VDC (and other even lower voltages) became common in microcomputers (sometimes completely replacing +5 VDC) as it both reduces power consumption and permits higher speed of operation.
What type of waves do computers use?
Computers do not use waves, they use a digital signal. Unlike a wave, a digital signal is composed of a sequences of high and low voltages. These voltages remain at a constant voltages for both high and low. For example, a high voltage may be 5v while a low voltage may be -5v. Computers are designed to interpret these as 1s and 0s, or binary - the language of computers.
Why is the alternating current voltage increased?
In order to be transmitted long distances, voltage is raised. At the destination, voltage is lowered again to be used. This permits transmission for several miles, which wold not be possible at lower voltages.
