Delicious

Delicious

"Delicious is a social bookmarking service that allows users to tag, save, manage and share web pages from a centralized source. With emphasis on the power of the community, Delicious greatly improves how people discover, remember and share on the Internet."

With this website i can save web pages that i have used in past school work, and will need in future work. This will enable me to keep track of useful information, instead of having to print pages or save them in word documents. Since Delicious is also on the Internet it will allow me to access these bookmarks where ever i have Internet access.

iGoogle

My iGoogle page allows me too:

• store important dates and appointments in my calendar
• make bookmarks of useful sites that could assist me in school work
• search through dictionaries and thesaurus's
• search wikipedia
• make sticky notes and reminders

This can be very useful for a school student as it allows you to keep organised, whilst being online.

Term 4 Work

SkyDrive!!

I have now set up my sky drive and created folders for all the different subjects i would be taking in year11. These folders will enable me to store work information for each of these subjects online and allow me to access them where ever i have Internet.

Selection and Repetition

Algorithms are composed of three basic structures;..... Sequence, Selection and Repitition. Solving a problem often involves makng a decision between two or more options. In an algorithm this process of making a decision is called selection.

Describe in plain english an algorithm for;

1. Moving through a set of traffic lights.

You stop at the lights and observe the colour of the light to determine whether to drive or not.

2.Deciding whether to take an umbrella to school.

You will look at the whether and decide if its cold enough or humid enough to need an imbrella in case of a storm.

3.Giving a student an A, B or C on their test.

You look at how many questions the student has gotten right and how many they have gotten wrong and decide whether their marks deserve an A, B or C.

Often an algorithm will often require you to repreat a task in order to solve a problem; when this is done in an algorithm the structure is called repetition.

Describe in plain english an algorithm for;

1.Adding the correct amount of cordial to water to make a drink.

You add a bit of cordial, test it, then add more until you reach the desired taste.

2.Filling a bucket with water.

You will add a little bit of water at a time until youve reached the limit or desired amount.

3.Blowing up a balloon.

You will blow up the balloon then stop and look at the size and blow more until youve reached the desired size.

Is your computer running? Well you better catch it ;)

Some say there is a revolution brewing in the world of computing…it goes by the name of cloud computing.

What is meant by a netbook? What is the “cloud” in cloud computing.

A netbook is a mini laptop, designed for mobility and wireless online activity. Cloud computing is a program that provides various services over the Internet in a whole new way.The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted.

What applications does Google docs offer online?

• Create documents, spreadsheets and presentations online.
• Share and collaborate in real time
• Safely store and organize your work
• Control who can see your documents
• Read user examples

Why would you want you documents stored in the “cloud” (online)?

Being able to store your word documents online opens up a whole new world of possibilities. This way you could do all you work documents online and then be able to show them to your boss via URL, you also no longer need to buy the latest word document as google self updates and is FREE!

What advantages do students and teachers find in Google docs?

" I use it to post to my blog, do writing assignments, type notes for reading assignments and many other things.I love it even more than I used to because if I'm somewhere without my MacBook and I need to take some notes on a computer I can easily do it... " This student is telling how google doc has made his school work easier and more accessible.

"In my attempt to avoid sitting through days and days of PowerPoint presentations in my high school computer classes (and boring the students in the process), I decided to upload each of my students Online Safety PowerPoint's to a Google account and the class joined the presentation. " This shows how a teacher has made learning more fun for the student and able for them to join in. This ultimately creates funner learning and more social(in a good way) classes.

Which netbook, if any would suit your needs? Explain.

I wouldn't necessarily chose a netbook. I feel its maybe a bit "too small". I understand its meant to be small for mobility but there's a line between accident prone small and handy small, and i just feel its crossed the line. I mean you could drop this thing and it would snap, you could sit on it and break the screen in, you could drop it down a street drain and you could easily miss place it.

The End Of My Search!

Okay after reading maybe over 6 different websites on URL's and IP Addresses i think i now, personally, understand what they are.. so now I'm going to teach you what an URL and an IP address is.

Definition!

URL: Uniform Resource Locator

IP: Internet Protocol

URL!

People use URL addresses everyday to find the specific website they want.Websites like http://www.blogger.com/ have become more familiar to us than street names. Thou do computers really use them? These URL addresses that we memorise are actually in no use to the computers, as for us its easier to remember a simple URL instead of a pattern of numbers.... and this brings us to IP ADDRESSES. When humans need to remember things it can take us some time and use of our mnemonic aid but... computers need no such thing. So instead computers use a serious of numbers called IP addresses to help them find a specific website.

There are many different types of IP addresses but the one mainly used by computers is a Dotted-Decimal Form. A dotted decimal form has 4 different numeric parts ,with each one separated by a period. An example of this would be Bloggers IP address which is 209.85.129.191.

The Structure of URLs

URLs can be broken up into separate segments and it can be confusing so I'll explain each part.

Protocol: The protocol determines how the information is determined and processed.A colon and two forward slashes always follow the designation of the protocol.The colon is an important part of the protocol name and assigns a device or process. The two slashes help distinguish what we are seeking from a local file.

User:Password@: The “user:password@“ section is rarely encountered by the average user but allows you to enter your user name and password for sites where that is required.

Host:Port: Ports aren't relevant for human use so explaining them could become quite difficult and tiring so an easy example is that HTTP is assigned port number 80. The “host” is the computer where the information that we want resides.

URL-Path: This is the path on the host computer to the particular page or file that we wish to download. This part will often have the name of a directory, then some sub-directories and then perhaps an html file.

Domains

For some time, these domains were limited to com, edu, org, net, mil, gov, and int. The com, net, and org domains are available to persons and businesses worldwide. Originally, they were supposed to be descriptive with com, net, and org meaning “commercial”, “network”, and “non-profit organization”, respectively. However, these meanings have become blurred. Anyone can apply for a domain containing org. The edu (education) domain is for properly registered four-year institutions of higher learning, i.e. colleges and universities.

And that's it for my description of URLs and IP Addresses, it was a long and tiring search but i learnt something so it was worth it, and hopefully you'll learn something too.

Home Address? NO! Try Internet Address (:

Home Address' all consist of numbers and the street name. While a Internet Address consists of a URL, and URL's are broken into three things;

1. The "Http" also known as the Protocol
2. The server name eg; www.howstuffworks.com
3. The file name eg; "web-server.htm"

The browser translates the server name into an IP address, and the IP address is basically a group of numbers that form your Internets unique signal.The four numbers in an IP address are called octets because they can have values between 0 and 255

My schools website is http://www.mcauley.nsw.edu.au, our domain name is McAuley Net, and to access our website we have to go through a protocol of entering user names and passwords to access our work, etc.
