3. Analog computers measures and answers the
questions by the method of “HOW MUCH “.
•Signals are continuous of (0 to 10V)
•Accuracy 1% approximately
•High speed
•Output is continuous.
•Time is wasted in transmission time
5. Digital computers
Digital computers counts and answers the questions by
the method of HOW MANY. The input data is
represented by a number. These are used for logical
and arithmetic operations.
Signals are of two levels (0V or 5v)
Accuracy unlimited
Low speed sequential as well as parallel processing
Output is continuous but obtain when computation is
completed
7. •Micro computers are the smallest computer
system.
•There size range is from calculator to
desktop size.
•It is also known as Grand child Computer.
•Applications- Personal computer, Multi
user system, offices.
9. •These are small general purpose system .
•They are generally more powerful and most
useful as compared to micro computers.
•They are known as Child computer.
•Applications- Departmental system, Network
server, Work group system.
11. •Main frame computers are those computers
that offer faster processing and greater
storage area.
•The word main frame comes from metal
frames.
•It is also known as Father Computer.
•Applications-Host computers, Central
data Base server.
13. •Super computers are those computers which are
designed for scientific job like weather forecasting and
artificial intelligence etc.
•They are fastest and expensive.
•It contains a number of CPU which operate in parallel
to make it faster.
•Application-Weather forecasting, Weapon research
and development.
15. •The combination of features of analog and
digital computers is called hybrid computer.
•The main example are Central Defense and
passenger flight radar system.
•They are also used to control the robots.
