Evolution of Computer
The invention of computer is not as simple as it may be. It took several years
to come up with the computing concepts and computer designed that we are
enjoying in the 21st century.
In the book of M. Frauenfelder (2015) entitled: “The computer, An illustrated
History from its origin to present day” discussed major concepts in the evolution
of computing categorizing it into 10. To see how far computers have come,
perhaps its best fisrt to look at how far they haven’t come.

Classification of Computer
In the GeeksforGeeks website, they categorized computers according to the
following:
1. Size
• Supercomputers : The super computers are the most high performing
system. A supercomputer is a computer with a high level of
performance compared to a general-purpose computer. The actual
Performance of a supercomputer is measured in FLOPS (Floating
Point Operations per Second) instead of MIPS (Millions Instructions
per Second). All of the world’s fastest 500 supercomputers run Linux-
based operating systems. Additional research is being conducted in
China, the US, the EU, Taiwan and Japan to build even faster, more
high performing and more technologically superior supercomputers.
Supercomputers actually play an important role in the field of
computation, and are used for intensive computation tasks in various
fields, including quantum mechanics, weather forecasting, climate
research, oil and gas exploration, molecular modeling, and physical
simulations. and also Throughout the history, supercomputers have
been essential in the field of the cryptanalysis.
Examples:
JaguarJaguar
16
PARAMPARAM Roadrunner
• Mainframe computers : These are commonly called as big iron, they
are usually used by big organisations for bulk data processing such
as statics, census data processing, transaction processing and are
widely used as the severs as these systems has a higher processing
capability as compared to the other classes of computers, most of
these mainframe architectures were established in 1960s, the
research and development worked continuously over the years and
the mainframes of today are far more better than the earlier ones, in
size, capacity and efficiency.
Example:
IBM z Series
• Minicomputers : These computers came into the market in mid 1960s
and were sold at a much cheaper price than the main frames, they
were actually designed for control, instrumentation, human
interaction, and communication switching as distinct from
calculation and record keeping, later they became very popular for
personal uses with evolution. In the 60s to describe the smaller
computers that became possible with the use of transistors and core
memory technologies, minimal instructions sets and less expensive
peripherals such as the ubiquitous Teletype Model 33 ASR. They
usually took up one or a few inch rack cabinets, compared with the
large mainframes that could fill a room, there was a new term
17
“MINICOMPUTERS”
coined
Examples:
• Microcomputers : A
microcomputer is a small, relatively
inexpensive computer with a
microprocessor as its CPU. It includes a
microprocessor, memory, and minimal
I/O circuitry mounted on a single
printed circuit board.The previous to
these
IBM z Series Desktop Computers in a
Computer Laboratory
computers, mainframes and
minicomputers, were comparatively
much larger, hard to maintain and more
expensive. They actually formed the
foundation for present day
microcomputers and smart gadgets that
we use in day to day life.
Examples:
Tablet Smartwatch
2. Functionality
• Servers : Servers are nothing but dedicated computers which are
set-up to offer some services to the clients. They are named
depending on the type of service they offered. Eg: security server,
database server.
• Workstation : Those are the computers designed to primarily to be
used by single user at a time. They run multi-user operating
systems. They are the ones which we use for our day to day personal
/ commercial work.
• Information Appliances : They are the portable devices which are
designed to perform a limited set of tasks like basic calculations,
playing multimedia, browsing internet etc. They are generally
18
referred as the mobile devices. They have very limited memory and
flexibility and generally run on “as-is” basis.
• Embedded computers : They are the computing devices which are
used in other machines to serve limited set of requirements. They
follow instructions from the non-volatile memory and they are not
required to execute reboot or reset. The processing units used in
such device work to those basic requirements only and are different
from the ones that are used in personal computers- better known as
workstations.
3. Data handling
• Analog : An analog computer is a form of computer that uses the
continuously-changeable aspects of physical fact such as electrical,
mechanical, or hydraulic quantities to model the problem being solved.
Any thing that is variable with respect to time and continuous can be
claimed as analog just like an analog clock measures time by means
of the distance traveled for the spokes of the clock around the circular
dial.
• Digital : A computer that performs calculations and logical operations
with quantities represented as digits, usually in the binary number
system of “0” and “1”, “Computer capable of solving problems by
processing information expressed in discrete form. from manipulation
of the combinations of the binary digits, it can perform mathematical
calculations, organize and analyze data, control industrial and other
processes, and simulate dynamic systems such as global weather
patterns.
• Hybrid : A computer that processes both analog and digital data,
Hybrid computer is a digital computer that accepts analog signals,
converts them to digital and processes them in digital form.

ACTIVITIES
Activity 5: Classification of Computer
Objective: Identify the following computer based on its size, functionality, and
data handling.
Material: Pen and Notebook Procedure:
1. Identify the following description.
2. Write your answer in the blank provided.
19
________________ 1. It is one of the classifications of computer that is based on
the the overall dimension of computer.
________________ 2. It is considered as the biggest computer, examples of this are
Jaguar, PARAM, and roadrunner.
________________ 3. These are dedicated computers which are set-up to offer
some services to the clients.
________________ 4. A form of computer that uses the continuously changeable
aspects of physical fact such as electrical, mechanical, or
hydraulic quantities to model the problem being solved
________________ 5. A computer that performs calculations and logical operations
with quantities represented as digits, usually in the binary
number system of “0” and “1”, “Computer capable of solving
problems by processing information expressed in discrete
form.
REMEMBER
There are various defintions of computer available but the common thing
are Computer is an electronic device, operate and functions because of programs
installed, and it follows an Input-Process-Output (IPO) sequence. There are
various classification of computers but based on Geeks for Geek Website, we can
classify it through size, functionality, and data handling. Moreover, computers
are so powerful that enabled us to become more effective and efficient in dealing
with our daily activities.
It is also noteworthy to think on the evolution of computer for us to be have
better understanding in inventing or innovating technologies. As cited in the
review on the book of M.Fraundeler, from the tiniest gadgets to vast scientific
simulators, computers are integral to our lives, and are developing at
everincreasing speed. The computer traces the evolution of this vital machine
from its earlisest roots through its existing application in code-breaking during
the second World War, from its initial use in the workplace and home, to its
current status as a totally indispensable – and increasingly portable – part of
twenty-first century life. Highly illustrated, the book brings home the rapid
reduction in computer size and growth in capacity, and its vast range of uses.
