Forth Quarter

Fourth quarter na Sir, andito na po yung project ko. Sana naman maawa ka na Sir sa akin, gusto ko po talagang makaflat-1. Dalian mo nalang Sir yung mga quiz at LT para maka-flat 1 ako. Joke lang Sir. Alam ko naman po na pinaghihirapan ang mga bagay na gusto mo. Kaya promise Sir aayusin ko na po ngayong fourth quarter. Ang astig pati ng lessons ngayon tapos may hands-on pa... Kasi nga, ang pro namin.Gets?  Sige Sir thank you nalang po sa grade na ibibigay mo. Okay na po ang 1.25 pero Sir mas okay ang flat-1. :))

Software

Software is anything that tells the computer what to do.

There are 2 types of Software.

1. System Software - take control of the PC's start-up and play a central role by maintaining, managing, and controlling the computer resources
Ex. Operating System- controls all the input/output and processing activities, PC hardware and operation of the other programs
      EX. Windows, Linux, Solaris
            

Ex. Compiler- use to create software
      Ex. GNU C Compiler, JAVA C Compiler

2. Application Software
Ex. Word Processors, Spreadsheet Software, Photo Manipulation. Media Player. Entertainment. Browsers

What is a platform?
     It is a processor and an operating system
Can a specific platform of a software run on other platform?
     No
What should I consider before choosing a platform?

• Availability of appropriate commercial applications software for the platforms. 
• Compatibility of platform with existing hardware, software, and expertise

Example of a platform.
     Wintel platforms like Windows XP, Windows 7, Vista

Cycle

I learned that the cycle in the CPU come from the Input Device where it will transfers the instructions and data to the Main Memory or the RAM. Then, the memory will transfer it the CPU where it will be process and the CPU will transfer the data back to the Main Memory while the instructions will be store in CPU. The memory will process it and transfer the result to the Output Device.

(P.S. I will not explain the second cycle or picture in the moodle because I can't understand it.)

Binary System

Binary is a number that includes only one and zero. Also called base-2. The "position values" in a binary number are the powers of two like 2, 4, 8, 16, 32, 64, 128, etc.
*Bi means "two" in Latin


Decimal is the numbers that we are used to seeing. Consist of numbers from 0-9. Also called base-10.

(Note: Every Binary number has a corresponding Decimal value (and vice versa).)

Coversion

These are some ways on how to convert. I will not explain it anymore because you know Sir that I understood this lesson. Besides, I don't know how to or I can't explain it.

• BINARY – DECIMAL [Positional Notation]

EX.     1100 0001_{2   =}  193₁₀

• DECIMAL – BINARY [Division by Two with Remainder] 

EX.     1024_{10  =}  0100 0000 0000₂

• BINARY- HEXADECIMAL [4bits = 1 hex digit] 

EX.      1001 0110 1111_{2  =}  96F₁₆

• HEXADECIMAL – BINARY [1 hex digit = 4bits]

Ex.     BDF_{16  =}  1011 1101 1111₂

• DECIMAL – HEXADECIMAL [Dec-Bin-Hex][ /16 ] 

EX.     229_{10  =}  1110 0101₂

• HEXADECIMAL – DECIMAL [Hex-Bin-Dec] [Place Values

EX.     A7D_{16  =}  1405₁₀
