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.

peopleware, hardware and software.. plus computer types part 3

Then if we have the peopleware and hardware, there will also be the software. Software is define as the program that we uses in a computer. 

We have two types of software. The system software and the application software.

System Software is the one that is responsible for operating a computer hardware. Application software is useless without the system software.

There are three categories of system software. System Control Program, System Support Program and System Development Program. They are somehow self explanatory.

First, System Control Program from the word itself, it is the one that controls the  use of hardware, software and data resources of a computer. Operating System is an example of it.

Then System Support Program is the one that supports the operations, management, and user's of a computer system. An example of it is the Antivirus. 

Lastly is the System Development Program. It helps users to develop information processing programs.

After the system software, we proceeded to the Application Software. Application software is define as any program we used on a computer, whether it is a game, a Microsoft office, a notepad, paint, Mozilla Firefox, Google Chrome and so many to mention. 

I also encountered the types of computers. I am really lucky because somehow it is only a recall for me.

The first type of computer are the supercomputers. They are somehow expensive for they are made for a specific function. They are used for scientific and military work. They are also the fastest computer.

    Next is the mainframe computer. It is not as expensive as the supercomputers. They are commonly used by the large corporations. It allows the information to be shared to other computers within the corporation. 

Minicomputers are also know as the midrange computers. They are cheaper than the mainframe computers.

Next are the microcomputers. Also know as the personal computers. These are commonly found in our own houses. These are used by one person at a time. 

Lastly would be the mobile devices. 

peopleware, hardware and software.. plus computer types part 2

Next are the Input Devices which inputs data inside the computer. 

Peripheral input devices examples are:

  *keyboard

*computer camera/ web cam

  *computer mouse

 *computer microphone

  * bar code reader

If there are input devices, there would also be the output devices. These devices are the opposite of the input devices. If the input devices inputs data, then the output devices would be the one that gives us the hard copy of a data or the one that  displays the data.

Some examples of these are:

 *monitor

  *printer

  *speaker

We also have the secondary storage. It is also know as the external storage. It allows the data or programs to be stored for future use. 

Few examples of it are:

  *magnetic tape

 *flash drive

  * floppy disk

  *memory cards

  * compact disk

And lastly are the communication devices. These devices provides the flow of data.  

peopleware, hardware and software.. plus computer types part 1

Peopleware are used to describe us, because peopleware is define as anyone who uses computer.


Then we have the hardware.

I must say that I have the advantage for this topic, for I already took up this lesson back then to "Introduction to Information Technology". 


With these session, I have learned the solid parts of a computer, which are divided into six categories. These are named as the central processing unit, primary storage,input devices, output devices, secondary storage and lastly the communication devices.

The Central Processing Unit is commonly mistaken as the system unit. But in fact, it is not the large metal case on a computer  set but rather a chip. It is the "brain" of a computer. Without it, there will be no computer, for it is the one that controls and process the task of a computer.
Also known as the microprocessor.

Central Processing Unit is consist of control unit, the arithmetic-logic and the primary storage.

Control Unit reads, interprets, and carries instructions. It does not change nor create a new data but rather directs it to the other components of the computer system. It also controls the input and output devices. It may only process one instruction at a time but it can execute instructions quickly(millions per second).

Arithmetic-Logic Unit, performs arithmetic and logic operations.

We also have the primary storage. It is also known as the internal storage, under the CPU. It temporarily stores the data on a computer. Examples of it are:

1. Registers 

2. Random Access Memory (RAM)

3. Read Only Memory (ROM) 

4. Cache Memory 

5. Flash Memory
