This document provides an introduction to analog and digital computers by defining each type, giving examples, and explaining their differences. It defines analog computers as those that perform functions continuously based on varying inputs like voltage or temperature using electrical or mechanical parts. Digital computers are defined as those that perform and accept converted binary data. Key differences outlined are that digital computers show results on screens while analog uses continuous voltage signals, digital works discretely while analog is continuous, and digital requires memory storage versus analog having no memory concept.

1. Welcome
to the first Projection

2. Welcome
to all of my students

3. Today we discuss about
● What is analog Computer ?
● What is digital Computer ?
● Difference between Analog and
Digital Computer.

4. What is 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.

5. Example
● Oscilloscopes
● Thermostat
● Thermometer
● Automobile Speedometer

6. Analog computer
is used to measure…...
● The electrical signal
● Current
● Frequency of signal and voltage
● Resistance of capacitor

7. What is Digital Computer ?
Digital computer is that
computer, which performs and
accepts the converted binary
number data.

8. Example
● Micro computers
● Personal computers
● Network servers
● Super computers
● Multi processor computers

9. Properties of digital
Computer
● Input can be in form of letters,
numbers written and represented in
special binary coded languages
● It uses two binary code or digits 0
and 1, which stands for no and yes,
false and true , left and right

10. Difference between analog
and digital computer
● Digital computer shows
result in computer
display screen, monitor,
CD or other peripheral
devices
● analog computer shows
output in form of voltage
signals and reading on
connected meters
● analog computer
produces continuous
voltage signals to
perform continuously
● Digital computer
performs work discretely

11. Difference between analog
and digital computer
● Digital computers
obviously requires
memory in shape of hard
disk, flash storage or
memory chip to perform
● There is no concept of
memory disc, drive or
chip in analog computer
