I have nearly finished with my assignment, i just have to make a couple of adjustments to some buttons but unfortunately the school doesn't have front page in most computers because they did a couple of adjustments during the holidays. Hopefully the library still has front page on it.
I used a different application from portableapps to finish my assigment and it does not make the adjustments i want to make so I need front page.
Other than that, i finished my assignment and I like what I have done.
After I finished that I will hand it in and then post more information on the website

What is an algorithm?
An algorithm in general sense is a set of general instructions which results in a predictable end-state from the knowing beginning. They are only good as the instructions given, however, and the result will be incorrect if the algorithm is not properly defined.
http://www.wisegeek.com/what-is-an-algorithm.htmWhat is Visual Basic?
Visual Basic or VB is the event driven programming language and is associated development environment. It enables rapid application development of the Graphical User Interface applications, access to database and
creation of controls and objects.

Hey Everyone!!!
This post is answers all the questions on the question sheet we were given. Hopefully I got them all right.
1. Define the term – Protocol
Protocol – a convention or standard that controls or enables the connection, communication and data transfer between two computing endpoints. In simple terms it’s a set of technical rules for the transmission and receipt of information between computers.
2. What are the following protocols used for?
TCP /IP – A Protocol used for transmitting data between computers and as the basis for standard protocols on the internet.
Full form transmission control protocol/Internet protocol
HHTP-is the protocol for the World Wide Web. The client/server protocol that defines how messages are formatted and transmitted on the World Wide Web
Full Form: HyperText Transfer Protocol
Smtp – is the internet mail transfer protocol. The mail protocol used to send emails on the internet. It consists of rules for how programs sending mail should interact with programs receiving mail/
Full form Simple Mail Transfer Protocol
FTP – is the standard protocol for transferring files. A standard procedure that allows on computer to transfer files to and form another computer over a network like the internet.
Full form file transfer protocol
3. What does GUI stand for? What was used before GUI?
GUI – is Graphical User Interface. . is a type of user interface which allows the user to interact with computer. Unlike a traditional interface GUI presents graphical icons, visual devices or special graphical elements known as widgets. These are much easier to use unlike in traditional interface where the user has to type in specific commands to open up information to do to any simple processing.
4. There are two methods of data transmission – serial and parallel. Explain the difference between them.
In Serial Transmission bits are sent over a single wire individually. While one bit is sent at a time high transfer rates are possible. This can be used over long distance.
In Parallel Transmission multiple wires are used in which it can transfer multiple bits simultaneously, which allows higher data transfer rates that can be achieved with serial transmission. This method is used internally within the computer, for example the internal buses, and sometimes externally for such things as printers
5. Define the term “URL”. Explain the components that make up the url.
URL – mean Uniform Resource Locator. It is the global address of documents and the other resources on the World Wide Web.
The first part of the address is called a protocol identifier and it indicates what protocol to use. The second part is called a resource name and it specifies the IP address or the domain name where the resource is located. The protocol identifier and the resource name are separated by a colon and two forward slashes.
6. In the context of data transmission, what is “error detection”?
In data transmission “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.
7. Name and explain one common method of error detection.
Two of the simplest and most common techniques are called checksum and CRC. More sophisticated strategies include MNP and CCITT V.42.

When creating a database that will be released on to the net, one should be careful as to what they are published. They should follow certain precautions as to avoid problems that will involve violation against the copyright laws. The copyright laws generally refer to a legal protection for people who express ideas and information on certain forms. The common forms are writing, music, visual images. The copyright protects the form or way an idea or information is expressed, but it does not protect the information itself. If copyrights are ignored serious penalties can apply which could lead to high fines or worse problems.
So if you are setting up, for example a music database, on the internet you should first get permission to post the database on the internet without getting into trouble with the copyright laws. Some of the options that could occur to you when trying to deal with posting a database on the internet would be to speak to the record dealers and get permission to post the songs on the net under your database. You could then write to the owner of the website that you plan to upload your database onto and explain to him that you have gotten permission to upload the music on to the website.
Sometimes you might have to approach the song writer or the artist depending on how serious the database you want to upload is. You will have to get their permission, if they say ok you will have to agree to their terms and then approach the website owner explaining that you have already got permission there will be no need for trouble.
Overall to make sure that you haven’t illegally put music on your database, don’t download music illegally. !!!
Having a database in a music shop is advantageous because it creates fewer distractions between the customers and the shop owners and workers, because a lot of time is spared if a database is created where the customers can go and view the music they wanted. The customers could enter the name of the album or track and locate the album on the shelves. When having a database, customers could listen to a track of their choice without changing CDs at all times if they need to listen to different tracks on different albums. It is also useful if you want to check the prices of the album.
It is made easier for the shop owners because they only have to update the database each time they decide to change it. So having a database in a music store is highly advantageous. It saves a lot of time for everyone!!

Hey People!! This is in Answer to Question 3.
I figured that a word tabel will be a little confusing so i drew up a diagram which seems less confusing to understand the tables, queries and forms that I ahve added in my database.
In the table I created these were the fields I created.
The Queries I used
The Parameter query enables us to search for a particular Artist, Album, or Track which will then reveal all the data under that particular category. Thus limiting our narrowing our search so that we don’t spend hours searching for one item on a long list.
Forms
The Artist Form was created to enable us to click on the button which will lead us to the Artist Parameter Query.
The Album Forms in turn does the same, enabling us to open the Album Query
The Tracks Form does the same as the two above.
The final form is a general form which allows you to update the information on the database without going and changing the table. It enables us to find records, save new ones, add or delete any records that we wish to.
Switchborad
the Switchboard allows us to navigate through the database.
The Add music button enables us to view the Music Form in add mode.
The Music Reports buttons leads us to view the general information on each track in the form of a report.
The Query button leads us to a sub menu where we find the buttons that will lead us to the forms Albums, Artist and Tracks, which will in turn lead us to the Queries.
The Exit button allows us to exit the database.
The back button allows to go back to the main menu.
Thats it.

Well I thought and thought and thought and finally came up with a game. Not the best of my ideas but I guessed it will do. You can the game for yuor self.
I looked at pther programs and saw how backgrounds were changed and then with a little bit of practise I managed to change the background using Broadcast and I recieve.
The next problem I solved again by using Broadcast and I recieve. This helped me to make things disappear when the object touched it.
I used variables to change and minus the scores.
I did my best and hope it will be ok.
You can rate it on my poll or you can comment on it
thats it for now
have a good holiday

Hey Everyone!!
Sooo much time has passed since I last posted something on my blog. Well this time it is about the problems I encounted while making a game.
This term we started on a program called Scratch. This program allwos to to make games, animations and many more. Our task this term was to create a game. So the problems I encounted during this time were:
!. What type of game was I supposed to make?
2. How could I make it intersting???
3. How could I change the backgrounds and make things disappear without making a mess of the program I made for the game?
4. How could I add the scores on to the game.
These were the problems I encounted during the process of making a game. I know these questions sound stupid but I am not soo good at when it comes to making games.
Thats it for now

Since I wasn't there when the assignment was handed out, at first I did not have a clue as to what I was supposed to do. When I was allocated to the Group that was doing Gadgets and Ports I was feeling better.
Problems that I faced were reallynot big major problems but all the same I faced them. Firtly I did not know create a blog or a wiki, because I my old school we never did these type of stuff. Jess helped me make a blog and wiki. As I started to get information I wasn't so sure that I got the correct information and I was worried if they were worng so i did not post my information straight away!! I also had to be sure that the information was correct in everyway and it had to be relating to the topic. Once I added my information it was OK. Mr. Lennon also told me that certain information was not needed so I deleted it!!
After feeling comfortable with my information and I was sure I was getting it right, I started postign pictures and then slowly addign links and horizontal lines.
I hope I do alright for this assignment because I really tried my best as a new student.
