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.

CAN YOU DETERMINE YOUR IP ADDRESS?

Helpful Sites
http://www.ipaddressworld.com/

http://computer.howstuffworks.com/question549.htm


My IP address is; 202.76.178.178
­­

The four numbers in an IP address are called octets, because they each have eight positions when viewed in binary form.

Class A - This class is for very large networks, such as a major international company might have. IP addresses with a first octet from 1 to 126 are part of this class. The other three octets are used to identify each host. This means that there are 126 Class A networks each with 16,777,214 (224 -2) possible hosts for a total of 2,147,483,648 (231) unique IP addresses. Class A networks account for half of the total available IP addresses. In Class A networks, the high order bit value (the very first binary number) in the first octet is always 0.

IP, a thing not thought about much, but constantly in use. So if this "language" confuses be sure to research more on IP address' cause they are an important thing.

Tim, O RLY??

Tim O'Reilly

In an early blog involving Web 2.0 i disgusts the views of a man named "Tim" but until now i never really knew who he was, so i took my time and researched him and found....Tim is the CEO of his own little company called O'Reilly Media. Tim spends his time publishing computer novels and is thought to be one of the best in that field. Thou Tim also spends his time hosting information forums in which he also held the intervention on the new Web 2.0 (which is discussed in a earlier blog), in which these inventions the "alpha geeks" determine the new trends in technology and higher intelligence. Tim's long-term vision for his company is to change the world by spreading the knowledge of innovators. To find out more about Tim go to his website tim.oreilly.com.

"You can thank Tim O’Reilly for all those classy computer-nerd books with line-art camels and gnus on the cover. But O’Reilly is more than a publisher. He’s also a vocal member of the net community and one of the ardent supporters of the open source movement. "
--Ziff Davis Smart Business

UPDATE UPDATE UPDATE!

Have you ever wondered what the internet was like when it first started off, well with website;

http://www.archive.org/web/web.php

You can search a website and go back to when it first made, or even just a month ago when a small update was made. I went on and typed in youtube and blogger and these are the websites when they first started off.

WEB 2.0 !!!!!!!!!!

DEFINITION!

• 'Tim says the phrase "Web 2.0" first arose in "a brainstorming session between O'Reilly and Medialive International." It was a kind of semantic deficit spending: they knew new things were coming, and the "2.0" referred to whatever those might turn out to be.'


• 'The story about "Web 2.0" meaning the web as a platform didn't live much past the first conference. By the second conference, what "Web 2.0" seemed to mean was something about democracy.'


• Web 1.0 was the base, on which Web 2.0 was to develope. Functions such as;

DoubleClick-->Google AdSense
Ofoto-->Flickr
Akamai-->BitTorrent
mp3.com-->Napster
Britannica Online-->Wikipedia
personal websites-->blogging
evite-->upcoming.org and EVDB
domain name speculation-->search engine optimization
page views-->cost per click
screen scraping-->web services
publishing-->participation
content management systems-->wikis
directories (taxonomy)-->tagging ("folksonomy")
stickiness-->syndication

Were all to change from one to the other as the web was developed. So Web 2.0 wasn't exactly a new creation it was more of an improvement to what is already known as The Internet.

USAGE!

• Web 2.0 personals are being employed within the public area, giving more use to the term Government 2.0. For example, Web 2.0 websites such as Twitter, YouTube and Facebook have helped in providing a possible way for citizens to connect with higher government officials, which was otherwise nearly impossible.


• Universities are using Web 2.0 in order to reach out and connect with Generation Y.Examples of this are: social networking websites – YouTube, MySpace, Facebook, Youmeo, Twitter and Flickr and virtual learning environments such as Moodle enable prospective students to log on and ask questions.


• Web 2.0 initiatives have been employed in public diplomacy for the Israeli government. The country is believed to be the first to have its own official blog ,MySpace page,YouTube channel, Facebook page and a political blog.


• Social Work 2.0 represents the use of interactive web technologies in the delivery of social services. Social workers use web 2.0 technologies for clinical practice, community organizing and administrative and policy functions. Social workers use chat programs to provide online therapy, or e-therapy. Web 2.0 technologies also allow for self-directed treatment through web-based modules. The use of Web-based technologies is not without its problems for social work. Social workers are state regulated, leading to concerns about providing services over the Internet to people in different states. Thou current licensee laws do not apply to services provided outside of the licensing state.

THE PEOPLES OPINION! (DEMOCRACY)

• In a podcast interview, Tim Berners-Lee described the term "Web 2.0" as a piece of jargon: "Nobody really knows what it means...If Web 2.0 for you is blogs and wikis, then that is people to people. But that was what the Web was supposed to be all along." In this quote Tim is saying that Web 2.0 isn't better, its still the same to people, with just a different name. This was intended to inflict an idea to the public that Web 2.0 is a waste of time and money as its identical to the programs their already using.
• Thou wikipedia is not a reliable source it does state some criticism on Web 2.0; According to wikipedia many people are concerned that Web 2.0 does not represent a new version of the World Wide Web at all, but merely continues to use so-called "Web 1.0" technologies and concepts. This idea could be remotely true as many of the ideas that Web 2.0 consists of had already been featured on the network systems well before the term "Web 2.0" emerged.
• Other criticism has included the term “a second bubble” (referring to the Dot-com bubble of circa 1995–2001), suggesting that too many Web 2.0 companies attempt to develop the same product with a lack of business models. This is because the company's are thinking of new programs,etc but they haven't an idea on how to develop them. Also these idea's seems to be so general that all the other company's are attempting to create them as well, and still calling them 'original'. So with this lack of process many of Web 1.0 programs are being included in the Web 2.0 criteria as there aren't as many features in Web 2.0.

KEY TERMS!!

1. Define the term – Protocol
A standard way of communicating across a network. A protocol is the "language" of the network. A method by which two dissimilar systems can communicate.

2. What are the following protocols used for? TCP/IP, http, SMTP, FTP

TCP is a protocol which runs over a network. Http is a protocol used for the internet (internet addresses). SMTP is generally used to send messages from a mail client to a mail server. File Transfer Protocol (FTP) is a network protocol used to exchange and manipulate files over a TCP computer network, such as the Internet

3. What does GUI stand for? What was used before GUI?

A graphical user interface is a type of user interface which allows people to interact with electronic devices such as computers; hand-held devices such as MP3 Players, Portable Media Players or Gaming devices; household appliances and office equipment with images rather than text commands

4. There are two methods of data transmission – serial and parallel. Explain the difference between them.

Serial transmission is the transmission of data along a single wire, whereas parallel transmission is the simultaneous transmission of a number of different binary digits by separate parallel paths.

5. Define the term “URL”. Explain the components that make up the URL.

Universal resource locator. The address of a website. The type of address (public, government, private, educational etc), the websites name.

6. In the context of data transmission, what is “error detection”?
Error detection is the ability to detect the presence of errors caused by noise or other impairments during transmission from the transmitter to the receiver. Error correction is the additional ability to reconstruct the original, error-free data.

7. Name and explain one common method of error detection.

Parity schemes; the stream of data is broken up into blocks of bits, and the number of 1 bits is counted. Then, a "parity bit" is set (or cleared) if the number of one bits is odd (or even). If the tested blocks overlap, then the parity bits can be used to isolate the error, and even correct it if the error affects a single bit: this is the principle behind the Hamming code.

THE INTERNET!

• 50 years ago the Internet was not even thought of or imagined, the basic usage for a computer was a basic database, and yet only one program can be used at once, limiting the activity progress.They had to be cooled constantly.Programming was manual work l it lead to bugs and virus’s.


• Batch processing; 1 process at a time (took a program to run, and ran yours and someone else’s and the results were printed and given to you; time sharing is a number of things going on at once)


• Time sharing, first idea to share information from one computer to another; whilst using multiple users.


• Around 1941 DARPA (defense advanced research project agency) was formed. Where they were researching how knowledge was transferred by people to computers.


• ARPANET would stop information from doubling up.


• 1966, the individuals didnt like sharing computers so they were giving their indivdual computer where they connected them to main frames, the little computer provided the information to the larger computer for the database.


• NCP (network control protocol) Transmission control protocol replaced it.
  Something to allow all the computers to share and connect with each other.


• File transfer was inspected, files where sent in smaller packets then reformed at the destination for quicker sending speed.


• Information always had a centre (larger database computer)


• Radio raves wud cause problems in atomic attacks, so they wouldn’t work anymore
  So now they use direct waves, but they don’t have long range.


• The French invented the INTER-NET A webbed connection of computers, data, etc (created a net like design).Connect the comps through gate ways.


• TCP finally merged the connections; creating the internet! (1990)
  They made a new set of rules so that it wud allow the internet to run, from a vote of majority.

The smaller computers connected to the main frame, sending signals and information to each other.

Data Types

Create a new database in Access. Call it “Data types”.
Access the help section of Access and type in the phrase “field data types available in access”
Create a record for each of the data types – you will need three fields as indicated in the help file.
Enter the data – try to summarize rather than just copying all of the help file

Querying A Database:

1. Open MS Access
2. From the file menu choose “open”.
3. “Point” to your database file that you saved on the network and click “open”.
4. You will then see the Database window shown below.
5. Select the query tab and then click the new button; ie. Let’s make a new query.
6. You will then be prompted for the type of format you would like to work with. Select design view.
6. You will now see two windows; “select query” and “show table”. You only have one table to work with. Your table is probably called “address”. Select it and click “add”. You should now see the table appear in the upper section of the “select query” window as shown below. You can now close the add table window.


7. Drag the field name “Surname” from the table into the first column of the row called “field” as shown above.
8. Drag “Name” and “Postcode” into the locations as shown. Enter a postcode you know is in your database; eg. 2145
9. Save the query (you will need to give it a name) then close it. The original database window should now be visible. You should notice that your query is now listed in the window.
10. Ensure your query is highlighted and then choose “open”.
11. What you now have displayed are the results of your query.

What sort of information has the query selected?
The query has selected all the information of the people with the post code 2146, which are mine and Shamona’s.


12. We can alter any query as follows. Firstly close the query and return to the main database window. With the “query” tab selected choose “design”. In the “or” row in the postcode column enter another postcode from your database; eg. 2146. Save and view the results of the query as before.

What sort of information has this second query selected?
It has now brought up the information from both the post codes 2146 and 2151 and the other information that came with.



13. Design the following queries and describe the type of information they are selecting.


Query 3 shows all the phone numbers which have the number *2* in them.

Query 4 shows all the phone number which have the number *3* in them.


14. Create the following queries and test to see they work. Record the fields and criteria you used for each query.

a) Postcode of 2145 or 2146.

b) Postcode between 2140 and 2170.

c) Surnames starting with F.

d) Surnames or first names containing "m".

e) Surnames and first names containing "a".

Creating A Basic Database

Creating a basic database……the address book

In this activity we will create a simple address book database consisting of a single table.
Visit the link below;
http://www.teacherclick.com/access2003/index.htm
Note: each tutorial is also available in video format if you click the camera icon

1. Using the directions in tutorials 2 create a database called address book and save it in your S: drive.
2. Using the directions in tutorial 3 create a table in the address book database with the following fields;
Surname, First Name, Date of birth, Home phone, Mobile, Postcode, Street, Suburb
3. Using the directions in tutorial 4 (under “Introducing and modifying data in a table.”). Add about ten records (People) to your database. Save the finished table

Database Definitions Activity Sheet

This is a simple activity whereby you can demonstrate your grasp of terms commonly used when referring to databases. Sites such as http://www.webopedia.com/ will be very useful in completing this activity.

Provide a basic definition for each of the following terms;
-FIELD: Financial Information Engine on Land Degradation (FIELD), a dynamic knowledge management system for searching, sharing and harnessing information related to sustainable land management financing.
-RECORD: anything (such as a document or a phonograph record or a photograph) providing permanent evidence of or information about past events
-FILE: A file is a collection of letters, numbers and special characters: it may be a program, a database, a dissertation, a reading list, a simple letter etc.
-QUERY: In general, a query is a question, often required to be expressed in a formal way.
-DATABASE: A database is a structured collection of records or data that is stored in a computer system.
-REPORT: A report is a very formal document that is written for a variety of purposes, generally in the sciences, social sciences, engineering and business.
-DBMS: DBMS is a computer software program that is designed as the means of managing all databases that are currently installed on a system hard drive or network
-DATA DICTIONARY: A data dictionary is a collection of descriptions of the data objects or items in a data model for the benefit of programmers.
















Illustrate, with the aid of a table or diagram, what is a file, record and field. Use the example of a database of music containing album titles, song titles, artists, genre etc.

-A file is a type of Database which can contain various layers. The first layer is the table which contains the information, broken up even more. Inside the table you have Records which organize the information more to make it more legible. Then the last layer is the fields which break up the records into different categories’ of information.

List as many commonly used databases as you think of – you should be able to come up with at least five.

-Music Albums
-Phone Contact Lists
-School Time Tables
-Classroom roles
-Games High Score Records

Found with the white pages.

• The Yellow/White Pages are a database, because they hold organized information which can be changed, searched or added at anytime.
• With the electronic Yellow Pages you can search quicker for business with only a broad idea of a location or shop genre, and you are provided with a map to assist you even more.
  
• With the Online/White Yellow Pages you can locate peoples houses , which gives a lack of privacy.

Lets try using the define feature in google……enter “define: database” into the search criteria. After discussing various definitions in class, record the one which is most meaningful to you.

Examples of Databases
Given your above definition what would be some examples of commonly encountered databases

Open your browser at the following address.
www.yellowpages.com.au

Use the website to answer the following problems.

1. I know there is a computer shop in the main street of Katoomba (Katoomba St.), but I don’t know its name. See if you can find the number for me.
2. Sally lives in Merrylands on Fowler Rd. and she wants to know the closest florist to where she lives. Help her out (see if you can get her a map).
3. You want the phone numbers of some motels in Noosa QLD. But of course your phone book only has NSW numbers?
4. Just for fun try the white pages and see if you can find a map of you or your friends house.
