How can we find the volume of a2d geometrical figure arhtematically?
I am not sure I can navigate through the typographic disaster zone here but it appears as if the question concerns finding the volume of a 2-dimensional geometric figure.If so, the answer is very simple: the volume is zero. By definition, 2-d figures can have lengths and areas but, since they do not have a third dimension, they cannot have a volume. In other words, VOLUME = 0.
What is the term for a device that converts digital data from a computer into analog signals and back again?
The devices are known very simply as analog to digital converters and digital to analog converters. They are frequently shorted to A-D and D-A converters. A complete analog to digital converter will not only convert the analog signal into a set of numbers, it will also format the digital data ready to deliver to the next step in the signal chain. In television, this means generating a fairly complex stream of data that will carry not only the picture but audio and other data as well. Digital to analog converters reverse the process and use the incoming data to generate an analog signal. In television, well know examples are the digital set top boxes. They receive digital data from an antenna and convert the numbers into analog audio and video signals.
How is data converted into signal?
Analog electrical signals are converted into digital signals by an analog to digital converter (ADC). A ramp is compared to a signal and comparator will send data bits to represent the signal value in digital value compared to a reference internal voltage.As you may or may not know, a bit has two values, 1 and 0. They represent a current going through a circuit. If the current is running, the value is 1. Otherwise, it is 0. Simple logic. Then there is Binary language, the very primitive way of how the computer communicates. It sends information in 1s and 0s, which then get interpreted. Of course, programming languages can't get pushed through the computer in the words that we see, so the computer must convert it into it's binary language.Bits do not have values at all. They do however have states, for example, 1= true and0=false. It cetainly does not represent current going, flowing or otherwise trough a circuit. It is however represent a binary state meaning two states . A COMPUTER DOES NOT CONVERT THIS STATES INTO BINARY LANGUAGE. However this is the language that all machines [COMPUTERS] understand; "1" and "0". Live and learn but do not pass along bad information please.
