If the Binary Number is the Computer's basic language, the Machine Cycle is the CPU's basic operation.


Now, how does this operation work?

       It consists of a sequence of 3 steps. 
Fetch. Decode. Execute.

FETCH

Retrieve an instruction from the memory.

DECODE

Translate the retrieved instruction into a series of computer commands.

EXECUTE

Execute the computer commands.

STORE

Write the results back in memory.

Conversion

At first, I had the "how-in-the-world-am-i-going-to-convert-these" look in my face when I saw the numbers flashed on the screen.

But then again, Sir Tom made it easy for us to apply conversion on these numbers.

From...

• BINARY – DECIMAL

• DECIMAL – BINARY

• BINARY – HEXADECIMAL

• HEXADECIMAL – BINARY

• DECIMAL – HEXADECIMAL

• HEXADECIMAL – DECIMAL

I now know how to deal with these numbers. Ha! Taste of victory. I feel like I'm a math pro right now (even though that could never happen lol).

Almost all things in this world occur in pairs.

Sun and Moon. North and South. Spoon and fork. Girl and boy. Tint and shade. Off and on. And even ONE and ZERO.

Now, what I am talking about?

I am referring to the binary number wherein only the ones and zeroes are included.

Because of its simple and elegant design, the binary number is used as the computer's primary language.

What is an Operating System?

Operating System. Do we really know one when we see one?

Well, let us first start with the definition of an operating system.





An operating system is a software that manages computer hardware and software resources and provides 
common services for computer programs.

                                                                

Still don't get it?

Windows 7, Windows XP, Windows 8, Ubuntu and Linux. Yeah, they're just some of the many operating systems. Now, do you get it? Great! :D
'Cause at first, I also did not know what is an operating system  :3

        We use computers in our everyday life. But do we really know what a computer system is and how it works?

A computer system is a complete, working computer. 

Computer systems will include the computer along with any software and peripheral devices that are necessary to make the computer function. Every computer system, for example, requires an operating system.

I'm back. :)

Hi guys! Missed me? Hope you did. 



    



'Cause now I'm back and I can't wait to spill out a bunch of awesome new techie stuff. :D






From computer systems to conversions and to the generations of computers, I'll be chitchatting with you. :)


Hope you guys enjoy my oh-so-techie-blog! ;)

I'll be saying goodbye to the 3rd Quarter. And I am now ready to face the Last Quarter and again, make my brain more awesome by learning more stuff about technology. :)

I hope you learned a lot from my blog and I wish you'll be able to apply these techniques in MS Excel.

 Ciao! :D
