IT
Fundamentals is a major subject that we IT students must study and this topic
will give us and introduction to the field we are taking up the INFORMATION
TECHNOLOGY.
But, before I
continue Information Technology is the study, design, development,
implementation, support or management of computer-based information systems,
particularly software applications and computer hardware.
Also, When
computer and communications technologies are combined, the result is
information technology—”infotech”—defined as technology that merges computing
with high-speed communications links carrying data, sound, and video.
In the first
day of our class the subject IT Fundamentals was introduce to us and give us an
overview about it. As our teacher said this subject requires a lot of
memorization and some topic requires computation.
In the
second meeting Miss discusses about.......
What is Computer?
Computer is
an electronic device, operating under the control of instructions stored in its
own memory unit, that can accept data (input), manipulate the data according to
specified rules (process), produce information (output) from the processing,
and store the results for future use.
What we
students usually don't know about Computer it is not only a device but a job
title. It was used to describe human beings whose job was to perform repetitive
computations.
Cyberspace....
The two most important aspects of cyberspace are the
Internet and that part of it known as the World Wide Web.
Internet is mother of all networks and a worldwide network
that connects up to 400,000 smaller networks in more than 200 countries while
World Wide Web is the multimedia part of the net and an interconnected system
of computers all over the world that store information in multimedia form.
Miss also differentiate the term Data and Information...
Data is the raw materials in the production of information while Information is a raw data or data that have been manipulated.
Miss also differentiate the term Data and Information...
Data is the raw materials in the production of information while Information is a raw data or data that have been manipulated.
As for its
History, we have been able to know the different persons who were responsible
for the development of computer.
Did you know
that the early aid for mathematical computations is not calculator or computer
but the Abacus, its only value is that it aids the memory of the human
performing the calculations.

The first programmer is Ada Byron / Countess Lady Lovelace she wrote series of "Notes" wherein she detailed sequences of instructions she had prepared for the Analytic Engine.

§Ada also invented the subroutine and was the first to recognize the importance of looping.
In addition, in
19th Century Holerith established a company called the Tabulating Machine Company which known today as the International Business Machines (
IBM). Then, the IBM and Harvard had a partnership and made the Marl
