Have you ever studied analog computers? Didn't think so.
The first system I worked on in 1978 was a military avionics unit containing 6 digital and 2 high speed hybrid (digital & analog) computers in a 6 inch square by 2 foot long box. Analog drifts and can rarely give more than 2 digit precision answers.
This is why computer technology is considered digital:
Because computers - like any other electronic device, uses numbers to represent information (and a single number is a "digit", in addition that a "bit" is a "binary digit"), and those numbers are sequenced in binary, in which it corresponds to a sequence of electric pulses, very much similar to the human brain. However in contrast the human brain has much more neurons than a conventional computer has transistors in a CPU, and therefore are able to represent these pulses into something more than just numbers (and not to mention the amount and pattern of brain signals are much different and longer per chunk of information compared to data on a computer.
Digital data is a binary system. Electrical switches only have two positions, or conditions, ON or OFF. Any number can be represented using a binary system and a system of electrical switches made of transistors can represent this binary system.
Electricity can now be used to manipulate numbers just by turning switches on and off.
By using groups of digits, timed pulses and simple programs, errors in binary data can be worked out and corrected. So there is little, or no, loss of data. An analogue computer would be more susceptible to interference and noise, with its infinite values.
So Digital binary data is the best way to use electricity and switches, to make a computer.
Let me think about this - um- increased reliability, lower cost, smaller size, lower energy requirements, fast operating speed. Pick one!
A computer only knows that all data is composed entirely of ones and zeroes - known as binary. Whereas, we use ABC and 123.
Digital computers are purely digital, i.e. they use digital(electronic) means to process data. Hybrid computers conversely use both digital and analog technologies.
It uses the Binary Numbering System.
Digital Data is data that is stored in binary, and a Digital Device is any device that works with binary data
No, most computers today are digital machines. Digital computers operate using discrete binary data, represented as 0s and 1s. Analog computers, on the other hand, manipulate continuous physical quantities such as voltage, current, or mechanical motion. While analog computers were used in the past, the vast majority of computers in use today are digital.

These are three main type of computers: Personal computer :- For Home and Business applications Server :-For Commercial use and data storage Super computers :- For Military, research work and weather forecasting
Pixels from a digital photo are transformed into a map and into data on a spreadsheet.
You can use computers or other digital equipment. OR You can use numbers and do arithmetic.

Computers are designed according to the data they are supposed to process. In this regard there are three types of computers Analogue, Digital and Hybrid.
