What is the difference between analog and digital computers device?

Answer 1

On The Lighter Side

An analog computer is the computer which is used not for home porpoises. Digital is. An analog computer is used to measure temprature and all. Digital isn't.etc.

Answer 2

Most of the world we experience may be described as "analog." If we roll a ball across a table, the ball smoothly passes every point in its path. When we watch a sunset we experience a smooth transition from light to dark. If we were to describe the rolling ball digitally we might take a measurement of its position at certain intervals, say one measurement each tenth of a second. Similarly, if we were to record the sunset digitally we would take a reading of the light at discrete intervals. Instead of a smooth transition, we get a list of numbers. If we take our measurement often enough we can play back our recording and it will appear to be smooth, just like you get when you flip the pages of those books with a slightly different picture on each page.

In music we used to record into the grooves in a record, the grooves zigzagging back and forth exactly as the sound waves they represent. Now we use Cd's which take a sample of the sound 44,100 times a second. Because a lest of numbers can be copied exactly, digital is a more secure way to store data but, there is always something lost between the samples taken.

Answer 3

An analog computer would be a slide rule, a digital computer would be a modern calculator.

An analog computer compares/multiplies/divides/adds/subtracts using analogs of the quantities involved.

A digital computer creates digital words to represent the quantities involved, then manipulates them digitally.

Answer 4

The difference lies in how the inputs are symbolized. With analog computers, the signal is proportional to some value such as current, voltage or distance. With digital computers, the signal is measured and becomes a number, usually a binary number.

Vinyl records are an example of analog computing, since the actual shape of the groove symbolizes the sound wave directly. CDs and other digital disks are digital, since the incoming sound wave is measured at every instant, turned into a number, then when played back those numbers tell the electronics how far to move the speaker.

Of course, the original digital computer is using one's fingers for addition.

Answer 5

An analog computer processes data in analog form while a digital one only processes data that's in digital form. A hybrid computer can process data that is in either form.

Answer 6

• An analog computer represents numbers as continuously variable quantities.
• A digital computer represents numbers as discrete coded symbols.
