Today like other inventions, computer has also become the part and parcel of our life. According to functions computer is of two different types, analog computer and digital computer. Both are used to perform and process the information or data and produce result in shape of output. The primary difference between analog computer and digital computer is that how they process and handle the data. Scroll down to know about analog and digital computer and differences between them.
Analog Computer:
Analog computer is that computer, which performs the functions continuously irrespective of variations in input, which can be in form of fluctuation in voltage or temperature, electrical or mechanical parts. Oscilloscopes, thermostat and thermometer are examples of analog computer. In start analog computer was used to measure the electrical signal, current, frequency of signal and voltage, resistance of capacitor, etc. Working with analog computer is not so easy. Number of electrical and mechanical peripheral and supporting devices are required for it to function properly.
Digital Computer:
Digital computer is that computer, which performs and accepts the converted binary number data. Today most of the computers are digital computers. It is basically an electronic based computer. Rather than continuous its input functions works discretely. Input can be in form of letters, numbers written and represented in special binary coded languages. Micro computers, personal computers, network servers, super computers and multi processor computers are kinds of digital computer. It uses two binary code or digits 0 and 1, which stands for no and yes, false and true , left and right. All instructions given to computer are performed through these two digits.
