information technology fundamentals, management, and maintenance.. 

It is a major subject, that we, as an information technology students must study. 

"primary, original, pertaining to a foundation" , 

- a definition you would get when you started to search for the meaning of FUNDAMENTALS alone..

Meaning, as an information technology students, we are oblige to study the foundation of our own chosen course. 

Indeed, we studied first the history of our "future best friends", the computers.

But before anything else, a computer is not just an electronic device, it is at first said to be a word used to describe a job title. A job in which a human is

capable of calculating the navigational tables, tide charts, and planetary positions for astronomical almanacs.

As for its history, we met different persons who were responsible for the development of computer. 

It started from the Chinese who made the abacus. 

Abacus helps people to make the calculations easier. 

After the abacus, punched cards was introduced by a Frenchman whose name was Joseph Marie Jacquard.

Then we were able to met our so called "great grandfather" Charles Babbage. 

He was the one who was responsible for the creation of the Difference Engine, which became the key for the discovery of the Analytical Machine. Analytical machine then became the foundation for the creation of our modern CPU.

Then came Ada Byron or Countess Lady Lovelace. She was the first one who recognized the importance of looping.

Also, in the nineteenth century, a company was developed and established. It is called the Tabulating Machine Company, which we now known as the IBM or International Business Machines. 

IBM then shared a partnership with the Harvard, and the result was Mark 1. 

One of Mark 1's programmer was Grace Hopper, she was the one who invented the word bug/debugging. This word was created when Grace Hopper found a bug inside Mark 1, and that bug was seemed to be blocking the reading of the holes in the paper tape. From there, she described the defect as the bug, then the word debugging took place. It is an act of removing the bug also known as the defect.

Aside from coining the words debug and debugging, she was also the one who was responsible for the creation of the Common Business Oriented Language also known as COBOL. 

After discussing the history, we also learned the Components of a Computer System, namely Peopleware,Hardware and Software.
