Along the way to describe about computer computer is devided into 3 type : is Analog Computers , Digital Computer and Hybrid Computer.
so let see the explanation about theme below
I .ANALOG COMPUTERS
Analog computers were well known in the 1940s although they are now uncommon. In such
machines, numbers to be used in some calculation were represented by physical quantities -
such as electrical voltages. According to the Penguin Dictionary of Computers (1970), “an
analog computer must be able to accept inputs which vary with respect to time and directly
7
apply these inputs to various devices within the computer which performs the computing
operations of additions, subtraction, multiplication, division, integration and function
generation….” The computing units of analog computers respond immediately to the
changes which they detect in the input variables. Analog computers excel in solving
differential equations and are faster than digital computers.
II .DIGITAL COMPUTERS
Most computers today are digital. They represent information discretely and use a binary
(two-step) system that represents each piece of information as a series of zeroes and ones.
The Pocket Webster School & Office Dictionary (1990) simply defines Digital computers as
“a computer using numbers in calculating.” Digital computers manipulate most data more
easily than analog computers. They are designed to process data in numerical form and their
circuits perform directly the mathematical operations of addition, subtraction, multiplication,
and division. Because digital information is discrete, it can be copied exactly but it is
difficult to make exact copies of analog information.
III. HYBRID COMPUTERS
These are machines that can work as both analog and digital computers.
