2nd Quarter Summary

What I've learned this 2nd quarter:

Know the different kinds of Protocols
Learn about the Top Level Domains
Know different tips and tricks in Web Searching
Follow the Netiquette
Make a webpage using HTML
Design a webpage using CSS

What I like about our topic is that it's very challenging and tricky, especially when our teacher ask us to make a webpage.

Making the webpage gave me a hard time, fun as the same, making it. At first, it is very depressing making it because it's very complicated because if mess up one of the code it will ruin the whole page, so I've worked slowly but not very surely. After making it, I was very happy because I know that I've worked hard making it, I gave it all I got. I'm very glad about the result of my hard work. :)

For more information

To know more about CSS and HTML, you can visit w3schools, and learn everything you need to learn.

http://www.w3schools.com/

CSS

Lets go to our next topic and that is CSS.
CSS stands for Cascading Style Sheet.

Cascading: Multiple styles can overlap in order to specify a range of style from a whole web site down to a unique element. Which style gets applied pertains to the rules of CSS cascading logic.

Style: CSS deals specifically with the presentation domain of designing a web page (color, font, layout, etc).

Sheet: Normally, CSS is a file separate from the HTML file –linked to the HTML file through its <head> (exceptions apply).

Significance of CSS

Allows for much richer document appearances
Reduce workload by centralizing commands for visual appearance instead of scattered throughout HTML doc.
Use same style on multiple pages
Reduce page size
Use HTML for content; CSS for Presentation.

3 Implementations

In-line - as attribute
Embedded/Internal - as a style tag
Internal - linked from CSS files

Selectors

Element Selectors
Class Selectors
ID Selectors
Pseudo Selectors

HTML Image, Hyperlink, Table

HTML Images

The <img> tag and Src Attribute

images are defined with the <img> tag

<img> tag is empty, which means that it contains attributes only, and has no closing tag

Src stands for "source" which contains the URL of the image you want to display.

example: <img src="banana.jpg" alt="batag">

example: <img src="balangay.jpg" alt="boat" width="300" height="400">

HTML Table

tables are define with the <table> tag

divided with rows (with the <tr> tag)

each row is divided into data cells (with the <td> tag)

<td> tag can contain texts, links, images, lists, forms, other tables, etc.

Header information in a table are defined with <th> tag

HTML Hyperlinks (Links)

<a> tag defines a hyperlink

hyperlink (or link) is a word, group of words, or image that you can click on to jump to another document

href document indicates the link's destination

example: <a href="http://www.anime-realm.com/">Watch Anime here<a/>

HTML Text Formating

Here are some HTML Tags:

Tags:

<big> Defines big text

<em> Defines emphasized text

<small> Defines small text

<strong> Defines strong text

<sub> Defines subscripted text

<sup> Defines superscripted text

<ins> Defines inserted text

<del> Defines deleted text

HTML Fonts and Colors

<font>

specifies the font face, font size, and font color of text
not supported in HTML 5. Use CSS instead.

<font>

element is deprecated in HTML 4.01

<div>

defines a division or a section in an HTML document
used to group block-elements to format them with CSS

<span>

used to group inline-elements in a document

HTML Color

Color Name
Hexadecimal Value

HTML

After discussing Netiquette. We go to our next topic, and that is HTML.

So, What is HTML?

HTML

stands for Hyper Text Markup Language
language for describing web pages.
is a markup language
A markup language is a set of markup tags
tags describe document content
HTML documents contain HTML tags and plain text
HTML documents are also called Web Pages.

HTML Tags

HTML markup tags are usually called HTML tags
are keywords (tag names) surrounded by angle brackets
normally come in pairs
the first tag in the pair is the start tag, the second tag is the end tag
The end tag is written like the start tag, with a forward slash before the tag name
Start and end tags are also called opening tags and closing tags.

HTML Elements

"HTML Tags" and "HTML Elements" are often used to describe the same thing
But strictly speaking, an HTML element is everything between the start and end tag.

HTML Attributes

HTML elements can have attributes
Attributes provide additional information to an element
Attributes are always specified in the start tag
Attributes come in name/value pairs like: name="value"

For me, HTML is the hardest topic that we tackled in our second quarter. It's very complicated compared to CMD in our first grading.

The Rules Of Netiquette

1. Remember the human
Test before posting/sending: Would you say it to the person's face? If not, reword and reread.

2. Behave online as you do in real life
Standards of behavior may be different in some areas of cyberspace but they are not lower than in real life.

3. Know where you are in cyberspace

Look around in new domains, listen to the chat, read the archives, figure out how people already there act, then join in and participate.

4. Respect other people's time and bandwidth
Ensure the time people spend reading your information isn’t wasted. No spamming - widely posting junk mail.

5. Make yourself look good online

You will be judged on the quality of your writing -spelling and grammar do count. Don;t post flame-bait (don't use offensive language or be confrontational for the sake of confrontation).

6. Share expert knowledge

Post resource list and bibliographies in the area of your expertise. The Internet was created for sharing information - help make the world a better place.

7. Help keep flame wars under control
Flame wars (series of angry letters between two or three people) are forbidden.
Flaming - what people do when they express a strongly held emotion without holding back any emotion.

8. Respect other people's privacy
You wouldn't look through a classmate's documents/messages, don't look through personal e-mail.

9. Don't abuse your power
Knowing more than others, or having more power than they do, does not give you the right to take advantage of them

10. Be forgiving of other people's mistakes
Everyone was a beginner, network newbie, at some point. Pointing out netiquette violations are often examples of poor netiquette. Think twice before pointing out mistakes and do it privately and politely.

(c) Sir Tom's Powerpoint Presention
.

Netiquette

After we discussed about the web tricks, we go to our next lesson which is about the Netiquette.

First of all, What is Netiquette?

Netiquette is the combination of Internet and Etiquette.

Internet - global system of interconnected computer networks that use standard internet protocol suite (TCP/IP) to link several billion devices worldwide.

Etiquette - The forms required by good breeding, or prescribed by authority, to be observed in social or official life

Netiquette - set of rules for behaving properly online

Internet + Etiquette = Netiquette

Here are The Core Rules of Netiquette:

Rule 1: Remember the human

Rule 2: Behave online as you do in real life

Rule 3: Know where you are in cyberspace

Rule 4: Respect other people's time and bandwidth

Rule 5: Make yourself good online

Rule 6: Share expert knowledge

Rule 7: Help keep flame wars under control

Rule 8: Respect other people's privacy

Rule 9: Don't abuse your power

Rule 10: Be forgiving on other people's mistakes

That's all, I hope learned something. :)

Just remember, Keep Calm and Follow Netiquette.

Tips and Tricks

Our teacher taught us some ways, tips and tricks in Web Searching

First is, Use Web Friendly Words.

For example, instead of saying 'my head hurts', say 'headache'

Next is, Less is More.

Less word search terms will give you more search results.

Third, Search with an exact phrase.

Put quotation marks around words to search for an exact phrase in an exact order.

You can also, Search within a specific site and search by file type and exclude a word or site.

example, Noragami:anime-realm.com. Add '*search item*:*insert site here*'
example, Diary ng Panget:pdf. Add '*search item*:*insert type here*'
example to exclude a word, DNP- panget. To exclude a site, DNP- site:wattpad.com

You can also get Time, Number & Currency conversion, Definitions.

We can also Check the Weather and Calculate.

DNS

Helloooooo. I'm here to tell you aaaaalllllll about our second topic. :D :)

The second topic that we tackled is Domain Name System or simply called as DNS.

Domain Name System is a hierarchical distributed naming system for computers, services, or any resources connected to an Internet or a private network.

Domain - contains a group of computers that can be accessed and administered with a common set of rules.
Subdomain - a domain within a domain.

Domain Name Space is organized into a naming hierarchy which is used to identify domains that are at different levels in the DNS domain hierarchical tree. Their purpose is to provide name server operations, which entails mapping a user-friendly name to a routable address.

This is the DNS Domain Hierarchical Tree.

Top level domains available:

.com - commercial organization
.edu - educational institutions
.org - non-commercial organizations and institutions
.gov - reserved by the United Stated for government entities
.net - companies involved in the Internet infrastructure
Country names - to be used by countries
.biz - added to accommodate businesses
.info - informational websites
.aero - aerospace companies
.pro - used by professional groups

Well, there you have it. But if you have any questions just comment them and I'll ask my teacher. XD HAHA.

Protocols

The first lesson that we tackled in second quarter in Kumsay (Computer Science) is all about Network Protocols. So, what are protocols?

According to Sir Tom, Protocols are set of rules that governs the communication between computers on a network.These rules include guidelines that controls the characteristics of a network like access method, allowed physical topologies, types of cabling, and speed of data transfer.

There are many types of protocols, here are some that we discussed in our class.

Internet Protocol (IP) - primary network protocol used in the internet.

Transmission Control Protocol (TCP) - connection-oriented network protocol.

User Datagram Protocol (UDP) - connectionless-oriented network protocol.

File Transfer Protocol (FTP) - transfers file from one host to another host over TCP-based network.

Simple Mail Transfer Protocol (SMTP) - internet standard for electronic mail (e-mail) transmission across IP networks.

Hypertext Transfer Protocol (HTTP) - foundation of data communication for the World Wide Web (www).

Address Resolution Protocol (ARP) - resolves IP addresses into user-friendly names.

Internet Control Message Protocol (ICMP)

Dynamic Host Configuration Protocol (DHCP) - dynamically assign IP addresses to network nodes.

Well, that's all I know... for know. But if you want to know more, you can always ask my teacher or search in the internet.

Bye! and remember, THEY'RE WATCHING YOU. HAHA.

Machines Of The Future

ARTIFICIAL INFORMATION

I picked this over the other topics because this topic caught my eye and this is the first time I've heard about this 'ARTIFICIAL KNOWLEDGE' or simply called as AI. Well what is AI? AI is an area of computer science that emphasizes the creation of intelligent machines that work and react as humans.

After I researched, surfed the net, and looked through articles and some books, there is this one thing they have in common when they define AI. They always say that, AI is an area of computer science that deals with giving machines the ability to seem like they have human intelligence. Human Intelligence that would allow them to do logical deduction and inference, have creativity, have the ability to make decisions based on past experiences and the ability to understand spoken languages. Some of the activities computer with artificial intelligence are designed for include:

Speech Recognition
Learning
Planning
Problem Solving

If you want to know the timeline of Artificial Intelligence you can visit this >>>>>> http://en.wikipedia.org/wiki/Timeline_of_artificial_intelligence.

For me, machines with Artificial Intelligence (considered as the 'Machines of the Future') are important and very useful today and for future use because this will help us to use them without struggling. Those machines already have a knowledge that would understand the person using it. This is also very convenient because this will help to finish a task faster and discover unexplored things. This also has less errors and defects and the function of this is infinite.

But in using this, we have to be very careful because this also have disadvantages like if something went wrong in the machine, it might do the opposite thing that they are assigned to do. If this is used wrong it might lead to mass destruction and it might also corrupt the younger generation's mind.

Second Grading Here I Come. :D

Hello Guys. :D
It's been a long time that I haven't post in my blog, a week or two? Nvmd.

I got 1.5 as my grade in CS 1 First Grading. :))

K. Share. :3

What I Like In CS1

What I Like In CS 1 (First Quarter)
* Can use the computer
* Air-conditioned classroom
* Cool and Young Teacher
* Easy Lessons (except for CMD stuffs)
* We use our moodle accounts
* Slippery Floor Tiles in Our Classroom
* A TV/Computer where you can also write a white board marker
* We can go to Aca 2
* Air-conditioned classrooms (Wait! Did I already said that?! XD)

Anyways, CS1 is fun in exciting especially when it comes to activities.
i'm looking forward in our Second Quarter, to be more exciting and fun. :)

Challenge. :D

While we're tackling the topic about File Formatting, Sir Tom gave us a challenge, we have to create a file with a file format named '.con' and the person who can get it can get a free Magnum Gold. Since the price is ice cream, I gave it all that I have just to get it, but unfortunately, I didn't. Fortunately, my classmates didn't get it too. :) HAHAHA XD.

After a few minutes, Sir Tom told us that we can't make a file named after '.con' because that file format is reserved for some application or program in the computer.

After he said that, my heart broke into pieces because I didn't get my ice cream. *sob* *sob*

Corny Jokes. :3

We all have this teacher that says jokes that is corny not funny but at the same time, it's funny because it not funny. Do you get me? HAHAHA XD. I know you don't. ;)

While we're taking our LT (Long Test) there's a certain number that almost the whole don't get the answer, (I forgot what number but I got it :D) Sir Tom gave us a clue. "Masarap ang prutas at isda kung..." that's the clue he gave us. It's kinda confusing if you don't really know the answer.

After a few minutes, when it's time to check our papers, he gave us the answer in his clue. "Masarap ang prutas at gulay, COMPRESSION (kung fresh 'yun)". We all just face palmed when heard that. But after awhile, we all just laughed because it was soo waley and corny. HAHAHA No Offense Sir Tom. :3 But srsly, it was KINDA funny, kinda.

Here's another, "Alam niyo ba 'yung References (ribbon in microsoft word), Kaklase niyo baga 'yan, si References Villarin". Haist. HAHAHA XD K. Bye Guyths. ;)

First Long Test

"OMG! OMG! OMG!"

Definition:
1. My expression when I forgot that it's our first long test in Computer Science. Pretty ironic, right? HAHA XD Well, that gives thrill to our simple life. Anyways, since I forgot to review, I was so nervous of what kind of test would our teacher give us, 'will it be a bloody one?' that's the first that popped into my mind. Since I can't scream out loud, all I can do is to shout inside my head. I opened to my moodle account and started taking the test. (We can also take tests in our moodle account).

2. My reaction to my final score. HAHA XD Wanna know my score? I got 20/25 it also means that I got 80%, and also means that I passed! Yeeey! Let's all rejoiceeee! Yey! Hey! ;) Luck is coming my way. :D

GO STOCK KNOWLEDGE!!

Here's another crazy yet miraculous experience in our CS 1. :D :D

"Tardyyy!" that's what my classmates greeted us *referring to me and my friend, Shiri*. ONCE AGAIN, We're 5 minutes late in our class. HAHAHA XD. Don't ask why ok? :3

When we went to our seats and started to listen to Sir Tom. I'm kinda confused of what they're talking about because they already discussed half of the topic. After discussing some things, our teacher gave us an activity about adding captions, index and bibliography in a document. I was just like "Oh My! What am I going to do? I didn't understand a word he said. Shocks!". Since, I'm too shy to ask some questions, I just go with the flow. HAHA XD Seriously, I just press random buttons.

While I'm pressing the buttons, our teacher approach me, "Ms. Villarin, di ka ata sa'kin nakinig". "Sir, sya po kaya." I justified, I listened ok? It's just that, nothing sync into my mind. Ok? XD After having some chit-chat , he left.

After he left, something came into my mind. I was so happy to remember that. I remembered how to add caption to a picture, add index and bibliography to a document. Yay!

I don't know. If it's just a coincidence or a miracle. :D

Command Prompt.

Command Prompt. Hayst. :3

Personally, I have a problem in coping up with the text-based navigation because the text-based navigation is sooooooo complicated, even more complicated than love. HAHA XD Jokeee. :3

But seriously, it's kinda hard for me to understand the command prompt chu-chus'. Like the cmd, cls, ren, move, del and etc.

Text-based navigation, why you so hard?! T.T -_-"

What I've Learned (Part 2)

Hellooo Guys. :D I'm here again.

Let me repeat this, sorry if there's any typos or wrong grammar. :3

The next thing that I've learned in Computer Science is that there are two Navigations. The first navigation is the Text-based and the second is the Graphical User Interface (GUI).

Text based is when you use the text or command prompt to command the computer.

GUI (sometimes pronounced as 'gooey') is when you can interact with gadgets like computer through mouse and etc.

In my opinion, I would prefer the GUI Navigation because it's easier to use and less hassle compared to text-based that would use different commands. :3

That's all. Night Guys. :)

No Perio, No Stress.

Good News:
Sir Tom won't give a periodical exam.
(Yeaaaah Boy! :D )
Bad News:
He gives a bloody quiz/LT. :3
Tsk. Tsk. -_-

What I've learned (Part 1)

Hello guys, it's me again.

As I've said before, sorry for the typos and wrong grammar. :3

Here's another post about what I've in Computer Science, so far. :D

Our first topic is all about Computer Science (CS). Computer Science is the study of computer and anything related to computer process chu-chu. :3

Sir Tom gave us an assignment about Information Technology (IT) and Information and Communication Technology (ICT) and their usage. At first I was just like "Whuut? What's the difference between IT and ICT? Well, except for the spelling of course".

I was so confuse to distinguish which is which. I cannot research about it because I didn't brought any laptop with me at school and I haven't got my library card to use the computers in the library. I decided to ask my classmate who has their own library card if they can research about IT and ICT.

The following day, I found out the difference between them. IT is used to restore, retrieve and manipulate data while ICT is the one who is responsible to spread these data.

I also learned that there are also difference between information and data. Information is raw data and Data is processed information.

That's all for now. I'll share another experience in my other post. Bye Guys! :D

First Meeting. :D

Ey Ey. Hellooo Guys. :D Especially to those who are nocturnal like me. ;)

This is my first post in my blog so, please bare with me. :3

Sorry if there are typos and wrong grammar, I'm not really good in English. :3

Let me share my first meeting experience in CS.

At our first meeting in our subject Computer Science, me and my friend, Shiri, were 5 mins. late in class because we went to the cafeteria 25 mins. before the time. Because we're late, all the seats in front were already occupied so, we get to sit in the back part of the computer laboratory which, I get to sit beside Anna Lynn and Joellee, two of the quite people in 7 - Sapphire. Luckily, the comp. lab. has air-condition in the back.

Our teacher, Sir Tomas Secundo, first introduced himself in the class then let us introduce ourselves in front of the class, AGAIN. Yeah, AGAIN, because we already introduced ourselves in different subject like 4-5 times already. He orient the whole class about the topic we're about to tackle in the 1st grading, the grading system and other subject matters. Then he, dismissed us. :) But I was not happy when he dismissed us because out next subject is Math. T.T

But, to sum it all up, being late in class in the first meeting was actually a blessing because I got a chance to sit near the air-conditioner and talk to two of the three quite people in out section. ^^
