dear Diary. reflectionSSSS..


B.S Information Technology. Did I make the right choice? Oh men, its like NO I didn't. 
When the subject Information Technology Fundamentals, Management and Maintenance was introduced its like, oh crap, yah, its like I chose the wrong course. 
It is said that this course requires a lot of memorization, ah, I say, Can I back out?
I hate memorization badly. Can I survive?

First session started quite good for me. Its like, I am just recalling my past lesson back to my high school days, well then i'm lucky that it was just the history.
But as the day passed, the pressure was already inside my body. I have to memorize a lot of names, and just what I said, I hate memorization.
My mind was already crowded. 
NO SPACE FOR NEW MESSAGES ang drama. 

When our first quiz came, I am still lucky that the questions that I encountered were quite easy. HA! Lucky for me that I knew the answers to those questions.

Then hardware came, which means a lot of memorization.
Memorization. Memorization. Memorization.

But then, the Number System came to my life. Oh men! Pede pa bang mag back out?
Its a little, or should I say the MOSt difficult part of our entire discussions.EVER.
I even got zero. Naiiyak na ako. Is there still a hope for me?

Then, natatandaan ko pa, we asked for the help of our kuyaS and ateS from higher levels. They gave us their time. Thanks to them. They taught us a few techniques about the number system. 
Really, its still confusing, or it is just because wala talaga akong patience dito? Or maybe, I am not meant for this course?
I'm losing hope. God help me.

After the number system, I already lost my confidence. I might be "over reacting" but, its the truth. Its hard to have a grade of zero for the previous quiz, lalo na kapag they compare me to my ate.
Its like, oo na, sige, siya na magaling, siya na talaga. 

But slowly, I am recovering from my failure. Umiikot nga talaga ang gulong. Hahaha. I'm lucky that our next topic was input/output devices. I'm lucky that I already took up this lesson back then to Introduction to Information Technology, the only difference is that, in here, mas detailed sya.

Alas, I completely recovered from my previous quiz. Even though we had our quiz after our discussion, pumasa pa din ako. :))
Hooray. 

Then, this course requirement came. Oh men, how will I enjoy my Christmas break?
But I think, this course requirement helped me. Narefresh ung mind ko sa previous lessons.
Then, its quite funny kasi kung kelan nagself study ako for the summary of our previous lessons, tsaka ko palang nagets ung number system at ung arithmetic operations. 

I know its just the beginning, so, maybe I should try harder.

And now...I would say..

Thats all. Thank you and Goodbye. :)

proGramming LanguageS (softWare)


Alas! This was the last topic that we discussed before we part ways for our Christmas break.

Programming Language are set of symbols and rules used to write program code. 


After knowing the meaning of programming language, we then proceed to computer generations.

Generations are the different stages of programming language.

In the programming language, we have five generations. 
The first generation is also known as the Machine Language.
The second generation is called as Assembly Language.
Procedural Language is for the third generation.
The fourth generation is called as Non Procedural Languages.
And lastly, the latest generation, the fifth generation is also known as the Natural Programming Language.

To simplify, here is the diagram of the evolution of the programming languages:


And that is the end of our discussion. 





arithmetic OperationS


Arithmetic Operations are also included in our subject Information Technology Fundamentals, Management and Maintenance.
There are basic rules for solving the arithmetic problems of number system.

0 + 1 = 1
1 + 0 = 1
0 + 0 = 0
1 + 1 = 0 (carry one)
or simply when the sum is even, instead of putting the real answer as the sum, you will write 0 and then carry 1.
1 + 1 + carry = 1 (carry one) 
or when the sum is odd, instead of putting the real answer as the sum, you will write 1 and then carry 1.

There are a lot of examples given to us so that we can understand this topic. 

manaGement.. Number sysTem.


In the previous post, I already gave the definition of the word fundamentals

Now, according to the definition of the word management, it is:

"The guidance and control of action required to execute a program. Also, the individuals charged with the responsibility of conducting a program."

Now, from the given definition, it means that we need to study *something* for us to execute and control a program. So indeed we studied a topic that was entitled number system.
Number Systems are the only language that the computer can understand.  



I would never forget this session. It is the start of a complicated topic that we must survive.
Within this session, I have once again encountered the number system. Although I already heard it back to my high school days, still this is different. It's deeper and it's confusing.

This session started quite good. Having different terms like any other session that we had. But as we went deeper, minutes by minutes had past, I had realized that, this is really a confusing one.




Especially when this slide was shown into the projector. Number System.  





Of course, we must learn it step by step, so we must first learn the basic things that we should remember, the equivalents.
It is said that when the number system is in a decimal, it means that it is represented by ten digits which are 0-9.
When it is binary, the numbers are only 0 and 1.
However, if it is on an octal, it should be eight digits namely 0-7.
And the most confusing of all, the hexadecimal which is composed of sixteen digits. The numbers 0-9 and the letters A-F. Letter A corresponds to number ten, then B is for eleven, and so on and so forth.

We must be reminded that these number systems should always be at our minds. We must not forget it, for these equivalents would play a great part on next topic, which is the
CONVERSION..

Well then, it is just the easiest part of conversion. But somehow it is already mind bugging thing, but I didn't expect that the next topic will be the hardest part of the number system.
