Introduction

The types of computers range from the Hybrid to the Analog types. The computers you come across
in the daily course of your day range from laptops, palmtops and towers, to desktop computers, to
name a few. But the very word “computers” reminds one of the desktop computers used in offices
or homes. Different categories of computes have been devised in keeping with our varied needs.

4.1 Classification of Computers

Computers are classified into various types based on purpose, technology used, size and storage
capacity and historical development as illustrated in Figure 4.1. We have already discussed the six
types of computers based on historical development. Let us categorise computers based on other
criteria.
