Etiquette in technology

Etiquette in technology governs what conduct is socially acceptable in an online or digital situation. While etiquette is ingrained into culture, etiquette in technology is a fairly recent concept. The rules of etiquette that apply when communicating over the Internet or social networks or devices are different from those applying when communicating in person or by audio (such as telephone) or videophone (such as Skype video). It is a social code of network communication.

Communicating with others via the Internet without misunderstandings in the heat of the moment can be challenging, mainly because facial expressions and body language cannot be interpreted on cyberspace. Therefore, several recommendations to attempt to safeguard against these misunderstandings have been proposed.

What is netiquette?

The word netiquette is a combination of ’net’ (from internet) and ’etiquette’. It means respecting other users’ views and displaying common courtesy when posting your views to online discussion groups.
WebWise Team | 10th October 2012
As you become involved with online discussion groups, you will find that each group has its own accepted rules of behaviour. Many of these have come about because of technical limitations.
For example, on an email discussion list - where not everyone may have seen past messages - it's considered polite to quote from a message you're replying to, so your response has context. It's also considered polite to keep those quotes short and relevant. On a web-based forum, however, where the original messages are visible to all, quoting is often unnecessary.

The basic rules

  1. Refrain from personal abuse. You may express robust disagreement with what someone says, but don't call them names or threaten them with personal violence.
  2. Don't spam. That is, don't repeatedly post the same advertisement for products or services. Most sites have strict and specific rules about who is allowed to post ads and what kind of ads they are.
  3. Write clearly and succinctly. On a site that has many non-native English speakers, avoid using slang they may not understand.
  4. Remember that your posts are public. They can be read by your partner, your children, your parents, or your employer.
  5. Stay on-topic, especially when you're new. Don't post about football in a hair-care forum or about hair care in a gardening forum!
  6. Don't expect other people to do your homework for you. If you're looking for technical help, for example, don't ask questions you could easily answer yourself by reading the manual or online help provided with the product. When you do ask for help, include details of what attempts you've made to solve the problem. It will save time and also show people that you are making an effort to help yourself.
  7. Do not post copyrighted material to which you do not own the rights. Sites vary in how strict they are about this, but as well as facing the possibility of legal action by the rights holder, you may also get the site sued.
  8. The site's owner, perhaps assisted by one or more moderators, has the final say in enforcing the rules.

Finally, it's always wise to see what the discussion group have been talking about for a week or two before you begin to post your messages. Online, as in real life, it can take a long time to get past a bad first impression.

Understanding DNS

DNS is an abbreviation for Domain Name System, a system for naming computers and network services that is organized into a hierarchy of domains. DNS naming is used in TCP/IP networks, such as the Internet, to locate computers and services through user-friendly names. When a user enters a DNS name in an application, DNS services can resolve the name to other information associated with the name, such as an IP address.

For example, most users prefer a friendly name such as example.microsoft.com to locate a computer such as a mail or Web server on a network. A friendly name can be easier to learn and remember. However, computers communicate over a network by using numeric addresses. To make the use of network resources easier, name systems such as DNS provide a way to map the user-friendly name for a computer or service to its numeric address.

The following figure shows a basic use of DNS, which is finding the IP address of a computer based on its name.
Example of DNS forward lookup

In this example, a client computer queries a DNS server, asking for the IP address of a computer configured to use host-a.example.microsoft.com as its DNS domain name. Because the DNS server is able to answer the query based on its local database, it replies with an answer containing the requested information, which is a host (A) resource record that contains the IP address information for host-a.example.microsoft.com.

The example shows a simple DNS query between a single client and DNS server. In practice, DNS queries can be more involved than this and include additional steps not shown here. For more information see http://technet.microsoft.com.

Networking: Protocol Definition and Importance

What is a Protocol?
A standard set of regulations and requirements that allow two electronic items to connect to and exchange information with one another. Protocols regulate data transmission among devices as well as within a network of linked devices through both error control and specifying which data compression method to use. In particular, protocols decide: the method of error checking, how to compact data (if required), how the transmitting device signals that it has concluded sending data, and how the receiving device signals that it has completed receiving data.

What is a Protocol?
A uniform set of rules that enable two devices to connect and transmit data to one another. Protocols determine how data are transmitted between computing devices and over networks. They define issues such as error control and data compression methods. The protocol determines the following: type of error checking to be used, data compression method (if any), how the sending device will indicate that it has finished a message and how the receiving device will indicate that it has received the message. Internet protocols include TCP/IP (Transfer Control Protocol/Internet Protocol), HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), and SMTP (Simple Mail Transfer Protocol).

Importance of Protocol
 
Protocol has key role in today's communication world, without protocol it is not possible for one computer to communicate with another computer.

Let have a example from daily life to understand the working of protocol in Internet.
Just Imagine you are in France but you don't know how to speak French. Is it possible for you to talk to a man who doesn't know any other language except French?

Well certainly not, although you could try to communicate with him non verbally but again you'd be unable to let him know your though or idea, to get the ball rolling either you need to learn French or this need to know the language that you speak, than you both would be able to talk comfortably, so from this example we can conclude that if two human want to communicate than they must speak same language.
This same analogy applies to Internet Protocol, if one computer machine want to send or receive information to another computer, than both of these computers must use same protocol to accomplish the task.

So now we can define Protocol as" The Rules that govern communication between two or more than two computers"

The common Internet protocols are as follow
1. HTTP (Hyper Text Transfer Protocols) helps us to view pages residing on another computer
2. FTP (File Transfer Protocol) helps us to send or receive file from one file to another file
3. SMTP/POP3 (Simple Mail Transfer Protocol & Post Office Protocol) helps us to send and receive emails

There are many like Telnet, IP etc but these are the most common that are used.

Guide for Creating Better Presentations

Making a Powerpoint Presentation is easy but making it more interesting and meaningful is hard. In order to achieve your goal to make one. I gather some useful information and guide from the net that will help us to improve our presentations. 

Grab your audience attention.  Creating slides that get the viewer's attention is not about how much you can fit on the screen. It's about using the space on your slides effectively. Don't crowd your slides, and only include elements that contribute to the points you want to make.

Minimize the number of slides. To maintain a clear message and to keep your audience attentive and interested, keep the number of slides in your presentation to a minimum.


Choose a font style that your audience can read from a distance. Choosing the right font style, such as Helvetica or Arial, helps to get your message across. Avoid using script fonts and over decorated fonts.


Choose a font size that your audience can read from a distance. Choosing the right font size helps to get your message across.


Keep your text simple by using bullet points or short sentences.   Use bullets or short sentences, and try to keep each to one line; that is, without text wrapping. You want your audience to listen to you present your information, rather than read the screen.

Use art to help convey your message. Use graphics to help tell your story. Don't overwhelm your audience by adding too many graphics to a slide, however. Make labels for charts and graphs understandable.Use only enough text to make label elements in a chart or graph comprehensible.


Make slide backgrounds subtle and keep them consistent.    Choose an appealing, consistent template or theme that is not too eye-catching. You don't want the background or design to detract from your message.

Use high contrast between background color and text color.    Themes automatically set the contrast between a light background with dark colored text or dark background with light colored text.

Check the spelling and grammar.  To earn and maintain the respect of your audience, always check the spelling and grammar in your presentation.

Use video and audio to convey your message more effectively. a brief video that illustrates an important point, is a great way to engage your audience. Using audio that helps convey your message can also help you keep your slides clean and approachable, such as by adding recorded narration to slides when sending your presentation to others to view on their own.

Use animations and transitions wisely. Having text and graphics appear on-screen just when you need them can be a nice touch. However, using too much animation can distract from your presentation's content. For effects that emphasize your points without overwhelming your audience, limit animation to key points, and use consistent animation choices throughout the presentation.

That's all folks! hope it helps you in creating your presentations..Ciao!--arcb

Protocol and DNS

Protocols and DNS
How I wonder what you are
I always see you and hear you but I don't know what you do
Oh Protocols and DNS tell me, tell me, what are you?


*tiiiing*

--Protocol:
Hi there, my full name is Protocol Set O' Rules. I am the manager of CBC(Communications Between Computers) Company.

--Someone:
Oh hello, Protocol! Ah, I see. Now, I know who you are. Thanks!

--Protocol:
No problem. By the way, do you want to know more about the company I'm working at?

--Someone:
Sure! Please do. I'm so enthusiastic about getting to know more of Mr. Protocol and his life.

--Protocol:
Haha, okay. I will introduce to you my subordinates.

First is Mr. Internet Protocol. He is one of the primary subordinates and he is often together with Mr. Internet Protocol.

Mr. Transmission Control Protocol. He is connection-oriented and greatly wanted by major Internet applications.

Next is Mr. User Datagram Protocol. Unlike Mr. TCP, he is connectionless-oriented. He is also very trusted because he never fails to let computer applications send messages.

Mr. File Transfer Protocol. He transfers files from one host to another over the networks of Mr. TCP.

Fifth is Mr. Simple Mail Transfer Protocol. He is an Internet standard for electronic mail transmission across Mr. IP's networks.

Mr. Hypertext Transfer Protocol. Without him, the data communication for the World Wide Web won't be present. He also works on hypermedia information systems.

--Someone:
Wow, because of what you told me, it makes me want to work for the CBC Company. I enjoyed my conversation with you, Mr. Protocol! Thanks for sharing.

--Protocol:
Oh, that's nothing. By the way, do you know the DNS(Domain Name System) Company?

--Someone:
No. What about it?

--Protocol:
We are planning to merge with that company.

--Someone:
Oh! That would be great then.

--Protocol:
Yes, it surely will. The DNS Company contains a group of computers that can be accessed with a common set of rules. It would be magnificent if our companies could be able to work together.

Cascading
Style
Sheet


vs.


Hyper
Text
Markup
Language


Use CSS for Presentation
Use HTML for content

CSS- can apply one specific style on multiple pages by just a few commands
HTML- will apply the same style only if you do it manually

3 Implementations:
1.) In-line
2.) Embedded/Internal
3.) External

Selectors:
1.) Element
2.) Class
3.) ID
4.) Pseudo

So what are you waiting for, go and use CSS now!


It will improve your websites. It'll make them more awesome!
It will reduce your work load.
It's hard but once you get familiar to it, it'll be easy as pie for you in no time.

What is HTML?

One year ago, I am a typical user of a computer I just normally browse internet and have no idea about how webpages are created. Without even knowing that I can do simple webpage now. HTML and CSS are the tools in creating webpage. For better understanding here are insights about it.

Short for HyperText Markup Language, the authoring language used to create documents on the World Wide Web. HTML is similar to SGML, although it is not a strict subset.
HTML defines the structure and layout of a Web document by using a variety of tags and attributes. The correct structure for an HTML document starts with <HTML><HEAD>(enter here what document is about)<BODY> and ends with </BODY></HTML>. All the information you'd like to include in your Web page fits in between the <BODY> and </BODY> tags.

HTML Formatting Tags

There are hundreds of other tags used to format and layout the information in a Web page. Tags are also used to specify hypertext links. These allow Web developers to direct users to other Web pages with only a click of the mouse on either an image or words. For a more complete list of HTML tags, check out the WC3 website.

HTML is the standard and most basic language in use to create web pages. It has a very simple code structure that makes it extremely easy to pick-up and learn compared to any other language.

HTML is rather simple with a few keywords that are dedicated for formatting words, sentences, or paragraphs. It is also quite forgiving with mistakes, still showing some result even when there are errors in the code. This aspect of HTML makes it quite easy to learn and write simple web pages that only contains a small amount of content and formatting. The problem with HTML is it doesn’t really scale that well once you start to develop bigger or fancier pages. Styling could involve multiple keywords in every section and this gets repeated multiple times in a single page, making the page unnecessarily longer. The simple and easy to learn language becomes very convoluted and quite difficult to trace once you’ve made mistakes.

When I say H, You say Hyper!
When I say T, You say Text!
When I say M, You say Markup!
When I say L, You say Language!

HTML on the go!

Without me, how will you be able to create awesome web pages?
Without me, how will you be able to visit your favorite social networking sites?
HOW?

That's why thanks to meeee. And ofcourse to my siblings.

Namely "Tag", "Element" and "Attribute"


*Tag's POV*
Hi, I'm Tag! I'm always surrounded by angle brackets. I also have two sons, Start and End. Start is older in a matter of minutes. And wherever they go, they are always together. You can barely distinguish the difference between them. Just remember that End has a forward slash.


*Element's POV*
Hey there, I'm Element! I'm always surrounded by the two children of Tag namely Start and End. And most of time, people often think that
 I am Tag. Probably because I'm always with his kids. And did I mention that we look so alike. Yeah, he is my twin brother, I forgot. -__- But I'm much more handsome than him. Remember that. Much mooore handsome.


*Attribute's POV*
Hello, person! I'm Attribute and I come in name or value pairs. I'm also the smartest among the three. The information I bring is really useful. And yeah, my favorite nephew is Start. I and Start are very much close to each other.

---The rest of the conversation---









So you see,  netiquette is really important.
And yeah, there are many other ways in order rules for netiquette.


Some are these:

You should make sure that the time people take in browsing your posts and reading your messages isn't wasted.
No to spam.
You should avoid flame wars.
You should behave properly online lke what you do in real life.

---And then the list goes on---


Even though I would not post many rules in order to achieve proper behavior at the net, as long as you know how to properly behave in real life and you apply it when you are in cyberspace, then surely, you would do no mistake! :D

Powerpoint Presentation and its Advantage




In today's time, computer and internet is one of the fastest and effective way of communication. It helps communicate from around the world. If you want to hear your thoughts from around the world or say something you feel in just a click the world will knows it. I know a way of delivering message to others by creating simple presentations. 

Powerpoint is a presentation software program that is part of the Microsoft Office package. It helps us to create reports, photo albums and many others. For me as a student, it is really a big help in providing information and also delivering message to my classmate or anyone who can read my work. The following are some of importance of Powerpoint Presentation:

  • Easy to use in reports by outlining 
  • Delivering message to the reader by picturing them the idea of a presentation
  • PowerPoint is regarded as the most useful, accessible way to create and present visual aids; 
  • easy to create colorful, attractive designs using the standard templates and themes; easy to modify compared to other visual aids, such as charts, and easy to drag and drop slides to re-order presentation.
  • easy to present and maintain eye contact with a large audience by simply advancing the slides with a keystroke, eliminating the need for handouts to follow the message.

In creating presentation be simple and specific. A Presentation has its mind on its own when you are looking at at the presentation it tells something to you it delivering message for just one click. Make presentation that the reader will understand what you are trying to present.--arcb


Creating Presentations that will Inspire People


Nowadays where the computer generation is constantly evolving, even students like me can motivate and inspire people by creating simple yet fully effective powerpoint presentations.

Today that we are facing a lot of struggles and difficulties like the the Super Typhoon Yolanda and other calamities,  we seem to give up and stop our saga towards reaching the top. As a student, I can make a difference by sharing what I've learned in school by the help of this

Motivation and inspiration are ways of giving hope to those who survived in any of  the troubles that they've encountered.

Motivation is about giving the person a reason to act positively and to continue on with his or her journey.

Inspiration, on the other hand, involves changing the way they think and feel about themselves. It taps into people's values and desires.

Who knows that by creating and sharing a simple presentation, I can move people and give them hope.-arcb
