Day 1 - Objectives

8. An electronic device that stores and
manipulates information. It is maybe in
the form of text, graphics, video, or
sounds. The instructions that direct the
computer are called software or
computer program.
Computer Definition

9. A computer is a programmable machine
designed to perform arithmetic and logical
operations automatically and sequentially
on the input given by the user and gives the
desired output after processing.
Computer Definition

10. Computer components are divided into two
major categories namely hardware and
software. Hardware is the machine itself and its
connected devices such as monitor, keyboard,
mouse and etc. Software are the set of
programs that make use of hardware for
performing various functions.
Computer Definition

11. The computer as we know it today had its beginning with a
19th century English mathematics professor name Charles
Babbage. He designed the Analytical Engine and it was this
design that the basic framework of the computers of today
are based on.
A BRIEF COMPUTER HISTORY

12. Generally speaking, computers can be classified into
three generations. Each generation lasted for a
certain period of time, and each gave us either a new
and improved computer or an improvement to the
existing computer.
A BRIEF COMPUTER HISTORY

13. In 1937 the first electronic digital computer was built
by Dr. John V. Atanasoff and Clifford Berry. It was
called the Atanasoff-Berry Computer (ABC). In 1943
an electronic computer name the Colossus was built
for the military.

15. Atanasoff-Berry Computer (ABC).

16. Other developments continued until in 1946 the first
general– purpose digital computer, the Electronic Numerical
Integrator and Computer (ENIAC) was built.
It is said that this computer weighed 30 tons, and had 18,000
vacuum tubes which was used for processing. When this
computer was turned on for the first time lights dim in
sections of Philadelphia. Computers of this generation could
only perform single task, and they had no operating system.
A BRIEF COMPUTER HISTORY
First generation: 1937 – 1946

17. Electronic Numerical Integrator and Computer
(ENIAC)

18. Electronic Numerical Integrator and Computer
(ENIAC)

19. This generation of computers used transistors instead of
vacuum tubes which were more reliable. In 1951 the first
computer for commercial use was introduced to the public;
the Universal Automatic Computer (UNIVAC 1).
In 1953 the International Business Machine (IBM) 650 and
700 series computers made their mark in the computer
world.
A BRIEF COMPUTER HISTORY
Second generation: 1947 – 1962

20. Universal Automatic Computer (UNIVAC 1)

21. International Business Machine (IBM) 650 700 series

22. During this generation of computers over 100 computer
programming languages were developed, computers had
memory and operating systems.
Storage media such as tape and disk were in use also were
printers for output.
A BRIEF COMPUTER HISTORY
Second generation: 1947 – 1962

24. The invention of integrated circuit brought us the third
generation of computers. With this invention computers
became smaller, more powerful more reliable and they are
able to run many different programs at the same time.
A BRIEF COMPUTER HISTORY
Third generation: 1963 - present

25. In 1980 Microsoft Disk Operating System (MS-Dos) was born
and in 1981 IBM introduced the personal computer (PC) for
home and office use.
Three years later Apple gave us the Macintosh computer
with its icon driven interface and the 90s gave us Windows
operating system.

31.  As a result of the various improvements to the
development of the computer we have seen the computer
being used in all areas of life.
It is a very useful tool
that will continue to
experience new
development as time
passes.

32. Computers are usually categories into three general categories:
COMPUTER FUNDAMENTALS
1. Super computer
The fastest, largest, most powerful and most expensive
computer.

33. Computers are usually categories into three general categories:
COMPUTER FUNDAMENTALS
2. Mainframe Computer
This is a little smaller and less powerful than the
supercomputer, but, like the supercomputer it is
also expensive.

34. Computers are usually categories into three general categories:
COMPUTER FUNDAMENTALS
3. Personal Computer (PC)
This is the computer that most people use in their
daily lives. This computer is much smaller, less
powerful and less expensive than the
supercomputer and the mainframe computer.

35. There are two main types of personal computers.
Macintosh (Macs) and the PC compatibles (PC). The main
differences between the two are the operating systems and
the processor they use.
This category of computer has two additional types of
computers. These are mobile computer and handheld
computer.
COMPUTER FUNDAMENTALS

36. The most popular type of mobile computer is the notebook
or laptop computer,
COMPUTER FUNDAMENTALS
and the handheld computer is a very small PC that you can
hold in your hand.
