LEANINGS OF THE WEEK - NAVARRA

In this week we really learned a lot of things. Especially thing related to card and computers. We tackled about the many things that are very useful for our future.

I learned that video card converts digital data into signals that can be sent across a connector to the monitor which interprets the signal into an image. I also learned that there are two basic categories of video modes:

· the text mode which is a type of monitor that displays only ASCII which stands for American Standard Codes For International Interchange.

· The graphics mode which is a type of monitor who can display any bit – mapped image.

I also learned about the expansion slots that are placed at the back of the computer and provide access to the AGP ( Accelerated Graphics Port ), PCI ( Peripheral Connect Interface) and the ISA ( Integrated Standard Adaptor ). I also learned that piezo speaker is a component of the motherboard and an example of Speaker that provides simple sound output.

I also learned that Internal Modem resides on an expansion board in order to connect to the internet. It also convert (modulate) the digital code into analogue waves and convert them back into digitals (demodulate) at the other end. There is also a power supply that supplies fuel to the computer. And the power cables that supplies power from the power supply to the drives. the colors of power cables indicates the power they contain such as the:

· Yellow wire furnishes 12 volts of power

· Red wire furnishes 5 volts of power

· Blacks that represent ground wires.

We also learned about the output devices that present, display, alters, or records output after it has left a computer’s system unit. The example of this devices are the Computer speaker that converts output data into sound, the monitor that is the most popular output device and the printer that creates images on the paper.

We also discuss about the input devices who generates input for the computer and allows the users to enter into the computer to be processed. The examples are:

· Keyboard that has 6 types of special keys namely Control key, Alt key, Shift key, Arrow key, Function key and the Caps lock key.

· Mouse that invented by Douglas Engalbert.

· Digital Camera that takes picture without a film.

· Graphic Tablet

· Joy Sticks

We also tackled about the peripheral devices that serve specific purposes

and enhanced the computer’s functions. The example of this device is the CD – ROM Drive, Modem, and the External Drive Unit.

I also learned about the 5 elements of Computing Process and they are the:

· Hardware – is the equipment involved in the function of a computer.

· Software – also called as the “programs”

· Data – is the raw facts that the computer can change into useful information.

· People – that are called as the “end users”.

· Procedures – are the steps or directions that the end user need to follow in order to complete a certain task.

We also discuss the Software and its types namely the Application Software, the Operating system, and the Programming languages. We also learned the generations of languages and that are the:

· Machine – language = is the first generation languages and is based in binary language that is difficult for human to use.

· Assembly language = is the second generation language that is used to shorten and simplify the process of programming.

· High – level language = is the third generation language that are like an English Language.

· The fourth and fifth generation of language are closer to the natural languages or rely on Graphical Development Interfaces (GUI).

We also touch in the development of the Word Processing Program:

· Electric Pencil = the first word-processing program for microcomputers

· Wordstar = more powerful that Electric pencil

· Multimate = the first program that made the IBM PC a Wang – Word Processor.

· DisplayWrite = made the IBM PC imitate an IBM Displaywriter.

· PC – Write = shareware you could try for free before sending a donation to the author.

These things are being discussed in this first week of August. These lessons will raely help in the future. And I know that this will last to our memory because this is discussed very – well.
