What type of signal does the computer use?

Answer 1

I will attempt to explain how a computer interrupts what we ask of it, & what we as as users should all understand in the simplest of terms I can :) At the core of a computer everything is processed from and into "On & Off"... (i.e. High or Low, One or Zero, +5 volts or 0 volts or Light and Dark as in fiber optics.)

The computer is hardware which interprets ON and OFF. A series or sequence of on and off force the system into a conversion too a resulting sequence of On and Off.

It is all Math - basic math based in a numeral system called Binary (a number system based using a 1 or 0 which is used to describe for us all character's and all numbers.

For the computer to display a numeral digit or an alphabetical character, a series of 7 - 1's & 0 are needed. This is called a "byte".

Each 1 or 0 in the byte is called a "bit". 8 bits make a byte! Seven bits for the character, and 1 bit for parity. (parity is a way for the system to verify that the resulting byte as correct.)

One Byte = one character 1

One Kilo byte = one Thousand characters 1,000

One Mega byte = one Million characters 1.000.000

One Giga byte = one Billion characters 1,000,000,000

One Tera byte = one Trillion characters 1,000,000,000,000

A computer processes this way while we greatly build the compatibilities to a point technology is at today, all off this basic binary platform.

And basically that is all a computer really does, only it does this very fast and it does this virtually without error. Most all system errors are the result of software in development (i.e. bugs) & compatibility issues, hardware failure, or user error.

"The computer only does as it is instructed, nothing more & nothing less." It's merely a box that churns out binary results from binary sums which it is tasked with too process.

Answer 2

Depends on the type of computer:

• Analog computers process Analog (Continuous) signals
• Digital computers process Digital (Discontinuous) signals
• Digital Signal Processors process Digitized Analog signals

Any analog type signal can be digitized for a digital computer and converted back to analog for the "real world".

Answer 3

The computer uses digital signals. They are all in binary code of 1s and 0s....such as 01100011000 might mean move this data to word....
