explain analog and digital computer?
Answers
An analog computer is a computer which is used to process analog data. Analog computers store data in a continuous form of physical quantities and perform calculations with the help of measures. It is quite different from the digital computer, which makes use of symbolic numbers to represent results.
Digital computer is the most commonly used type of computer and is used to process information with quantities using digits, usually using the binary number system. An example of a digital computer is a MacBook.
Analog computers process analog, i.e. continuously varying, data. Digital computerprocess data which is binary, i.e. in the form of 0 and 1. Analog computers operate on mathematical variables in the form of physical quantities that are continuously varying. For example temperature, pressure, voltages, etc.The basis of the working of the analog computers is modeling. Any real physical process can always be replaced by a mathematical model having the same properties.
Digital computers deal with mathematical variables in form of numbers that represent discrete values of physical quantities. The advantages of digital computers are that they are versatile, reprogrammable, accurate, and less affected by outside disturbances. In contrast to analog computers, digital machines work on numbers. Each variable is converted into numbers and each number into binary form, i.e. 0 and 1. It is this combination of 0 and 1 that does all the calculations. All modern computers, laptops, and calculators are all digital computers.
