Project ideas
Now i've decided that i'm going to carry out my plan for building on Pong. I've decided to build 2 extra levels on it that get harder. In the second level i'm making it harder by making to ball go faster. In the third level i will attempt to add in 'powers' such as an extra point or making the paddle get bigger. There will also be bad powers such as a smaller paddle or lose a point. This level will also become harder because the ball will be moving at high speeds and the powers can help you to lose.

Scratch
The second tutorial is Key Moves, this tells you how to make your sprite move in any direction when you press any arrow key. Here the only two blocks you choose are Motion and Control. In this tutorial also i changed the scene of the stage.
Moving Animation is the fourth tutorial which helps the sprite move like an animation. It teaches you how to change your sprites costume and move at the same time.
The fifth tutorial is Say Something. In this one you learn how to make your sprite talk.
The sixth tutorial that I did was Surprise Button, this one lets you add in a button that chooses the sound randomly from the files chosen making it "surprising".
The seventh tutorial is Animate It, this tutorial teaches you how to make a simple animation.
The eight tutorial is Change Colour. It tells you how to change the colour of the sprite by pressing any key.
The ninth tutorial is Dance Twist, it makes you play a sound clip and do a body twist.
Follow the Mouse is the tenth tutorial that teaches you how to make your sprite follow the your mouse pointer and move in any direction.
The eleventh tutorial, Glide, teaches you how to glide from one place to another. It helps to move smoothly without any disturbances.
The last tutorial is Interactive Whirl, this teaches you how to twist a picture out of shape by moving your mouse pointer. Now that i've done all the tutorials and added some snapshots i can start on the challenges.

Computer Algorithms
they only do what you tell them to!”
Using the web, find definitions for the following terms and post them on your blog. Make sure the definitions relate to computers and programming.
1. Algorithms- A set of clear instructions to complete a task in a finite time.
2. Pseudocode- An informal language that helps programmers develop an Algorithm.
3. Machine Language- A system of instructions executed by the computer's CPU.
4. High Level Computer Language- A type of programming laguage that isn't limited by the type of computer or by one specific job.
5. Flowchart- A type of diagram that represents an algorithm process.
6. Sequence- The order in which something is done.
7. Selection- Choose. If and Then.
8. Repetition- Repeating a sequence of instructions.

In your algorithm write each step of the process on a new line. Remember not to assume the computer knows anything.
1. Opening a door and entering a room-
- Stand in front of the door,
- Lift one hand up towards the doorknob,
- Squeeze the doorknob lightly,
- Twist it in a clockwise direction,
- Pull the door towards you,
- Let go of the doorknob,
- Walk through the door,
- Enter the room.
2. Negotiating traffic lights as you drive down a street-
Red Light= Stop, Green Light= Go, Orange Light= Slow down, prepare to stop.

Broadband Research
1. What is broadband?
Broadband is a term that is used consistently with different types of internet connections. Generally, it is referred to Internet connections over fiber optic cables rather than telephone lines. Broadband in telecommunications means a wide range of frequencies that are available to transmit information.
2. Outline the methods of delivery of broadband (wireless, cable, ADSL and fibre)? Identify the speed of each method.
Wireless Broadband is a fairly new technology that provides high-speed wireless internet and data network access over a wide area. In telecommunications, cable Internet access (often called simply cable Internet) is a form of broadband Internet access that uses the cable television (CATV) infrastructure. The fastest cable broadband goes is 300kbps. Asymmetric Digital Subscriber Line (ADSL) is one form of the Digital Subscriber Line technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL offers differing upload and download speeds and can be configured to deliver up to 6 Mbps from the network to the customer that is up to 120 times faster than dialup service and 100 times faster than ISDN. Fibre Broadband uses Fibre Optic cable to deliver data and is able to deliver it faster and also much more of it than can be done with the existing copper wires currently in use.
3. Discuss the advantages and disadvantages of each method.
Advantages of Wireless- Easy to add stations as there are no cables required. Signals can be sent through doors and walls so the stations can be mobile so can move around. There is less need for technical support in setting up due to their simple nature. There are no cables to trip over so there are less health and safety issues to consider. Share resources like printers. Have shared access to a centralized storage.
Disadvantages of Wireless- It's a bit more difficult to setup properly. Risk of 'outsiders' accessing your network unless robust security protocols are enabled (eg WPA, WPA2). Significantly slower than a wired network (2 – 50 times slower). The network can be less stable. Wireless reception may be impaired by a number of factors including large distances or objects between wireless devices, and other wireless networks.
Advantages of Cable- The fact that cable Internet doesn't require a phone line means that you always have a ready connection. Cable Internet is substantially faster than other connections such as dial-up, wireless and ADSL. Cable Internet supports data-heavy activities such as online gaming, so your playing experience will be of higher quality. Because cable is so much faster you will spend less time online.
Disadvantages of Cable- Cable Internet does not always operate at the highest possible speed. Initial connection can be expensive. Not all areas can access cable Internet. Cable may be a wasted expense for those who do not use the internet regularly.
Advantages of ADSL- It is extremely affordable. Internet connection by existing infrastructure. Using telephone line for Internet access as well as for conversation at the same time. Active connection without charging. Internet surfing without telephone impulses charging. Data transfer with download speeds 15-20 time higher than connection speed possible by analogue modem.
Disadvantages of ADSL- The first downside is that ADSL pricing can be very variable. The speed of your ADSL connection may suffer, as ADSL is very affected by physical distance. ADSL is also affected by how many other people are using your line. ADSL downloads much faster than it uploads.
Advantages of Fibre- Fibre optic data transmission is incredibly fast. Fibre optic cables can transmit data over exceptionally long distances without much data loss. Many gaming systems and home theater components now also transfer information back and forth via fibre optic cables.
Disadvantages of Fibre- Fibre optic cables are not susceptible to RF (radio frequency) interference. Fibre optic cabling can cost more than double what a typical broadband connection costs. Fibre optic connections are not available in many areas.
4. Give examples of broadband providers and identify the costs.
Yes Optus- 6GB of data for $30.00 every month. 14GB data for $50.00 every month. 2GB data for $20.00 every month. 5GB data for $59.99 every month.
BigPond- 3GB of data for $29.95 every month. 3GB data for $49.95 every month. 1GB data for $19.95 every month.
Virgin- 6GB data for $39.00 every month. 500MB of data for $15.00 every month. 6GB data for $39.00 every month.
5. The Federal Government is thinking of rolling out a national broadband network (The NBN). Research the NBN and find out:
a. what method of delivery it will use- NBN plans to deliver the best, most cost effective infrastructure across Australia using a combination of fibre, wireless and satellite technologies.
b. the expected speed- NBN plans to deliver fibre-based coverage with speeds of 100 Megabits per second. Premises in areas that cannot be serviced economically by fibre will be connected by advanced wireless technology providing speeds of 12 Megabits per second.
c. the expected costs-
6. Do you think Australians should invest in The NBN? Justify your answer.

Bluetooth
What is it?
Bluetooth is the name of a wireless technology standard for connecting devices, set to replace cables.
What do we use it for?
You use bluetooth so you can connect mobile phones and headsets to your computer, so your bluetooth headphones deliver stereo quality sound without wires, to be able to send photos from your camera to your computer without the need of wires and many more.
How is it part of our multimedia world?
Bluetooth is able to send multimedia from one device to another device without the use of wires and cables.
Are there different types? What are the advantages/disadvantages of each type?
There are no different types of Bluetooth but there is a variety of bluetooth accessories you can get.
A "simple" explanation of how it works.
Bluetooth uses radio frequencies in the 2.45 GHz range to send information over short distances of generally 10metres or less. By embedding a Bluetooth chip and receiver into products, cables that would normally carry the signal can be eliminated.
A rough indication of the cost of the device
Bluetooth doesn't necessarily have a cost because it mainly comes with the device that is bought for example, a laptop or mobile phone. But the many accessories Bluetooth can come in have different costs.
Future directions, what is waiting around the corner, what is the next "new" technology in this area?
The new version of Bluetooth technology will meet the high-speed demands and cater to the needs of low power applications. The next version of bluetooth, also called Seattle, will have many of the same features as the current one but will be capable of very fast data transfer and also being power efficient.

Secondary Storage
What is it?
Blu-ray Discs (BD) is an optical disc storage medium designed to supersede the standard DVD format. A Flash Drive is a small storage device that can be used to transport files from one computer to another. There are many different types of Flash Drives, such as USB flash drive or solid state drive.
What do we use it for?
Blu-ray Discs (BD) were established to hold a standard-length movie in HDTV format, or high-definition television.The movies are displayed in higher resolution and therefore they require much more storage space. Flash Drives are used for many different things. Because of its small size, many people find them very handy. They are mainly used for Personal data storage, maintenence, law enforcement, boot computers and business uses.
How is it a part of our multimedia world?
Blu-ray dics are a part of our multimedia world as they are able to encorporate many types of multimedia onto the discs. Flash drives are also a part of the multimedia world as they can store as much media onto it as possible.
Are there different types? Advantages/ Disadvantages?
There is only one type of Blu-ray discs. There are two main types of Flash drives, USB flash drives and Solid state drive. The most familiar one is the USB flash drives, this flash drive will let you plug the small drive directly into your computer and you will be able to access it as a drive on your computer. It will allow you to copy information to it as you need to. The Solid state drive is not as popular, and is used to store solid-state data that is persistant.
A "simple" explanation of how it works.
Blu-ray Discs store digitally encoded video and audio information in pits -- spiral grooves that run from the center of the disc to its edges. A laser reads the other side of these pits to play the movie or program that is stored on the DVD. A flash drive is easy to use. Once you have created a paper or other work, simply plug your flash drive into a USB port. The USB port will appear on the back of a desktop computer’s PC tower or on the side of a laptop. When you option to save your work by selecting “Save As,” you will find that your flash drive appears as an additional drive.
A rough indication of the cost of the device
A 25 gigabyte Blu-ray disc costs about $2.60 and a pack of 15 costs $40. The cost of flash drives range from under $10 to over $200 depending on the manufacturer and storage capacity.
Future directions, what is waiting around the corner, what is the next "new" technology in this area?
Since the Blu-Ray disc's launched in 2007, its acceptance as DVD media replacement has significantly increased. Blu-ray has had much support from consumers as well as movie studios and this has greatly contributed to its triumph over HD-DVD. The positives of Blu-ray had people believing, from an early stage, that it would be the future of high definition media. The USB flash drive, a relatively new invention that was first sold in 2001 as a humble 8Mb storage device. Their memory capacity continues to rise while their prices keep dropping. Today a 64 Gigabyte flash drive is not unheard of, and smaller drives can be bought for less than what a stack of blank CD's might cost. WEBSITES:

Piracy and Copyright
What is it?
Piracy is the stealing of others rights such as a book, story, invention or idea. In music, piracy is when you copy a CD or music for your own personal use. To make copies of discs to sell for profit is piracy. Copyright is a type of property that is founded on a person's creative skill and labour.
What do we use it for?
People make pirate copies of other peoples things to sell to other people and gain money of their own to make a profit. Copyright is there to protect the works and labour of a person and prevent unauthorized use of the work that is created by the original person.
How is it a part of our multimedia world?
Piracy and Copyright is a part of our multimedia world because they are both related to media. In the case of Piracy, the person who creates the pirated copy is using media to produce the extra copies. In Copyright, you need it to protect different types of multimedia such as film or music.
Are there different types? What are the advantages/disadvantages of each type?
There are no different types of Piracy or Copyright.
Future directions, what is waiting around the corner, what is the next "new" technology in this area?
Piracy and Copyright have no "new technology" waiting to come out but the avoidance of getting caught for Piracy is reducing and it is becoming harder to produce copies of something that is not theirs.

Digital Televisions
What is it?
Digital TV is a term that is used for encompassing High Definition Television and other applications including Standard Definition television, datacasting, multicasting and interactivity. Digital Television is the sending and recieving of moving images and sound by digital signals.
What do we use it for?
The main things we use digital televisions is to recieve better quality pictures and sound quality through digital signal processing. It is also used to introduce new services such as multicasting and datacasting. Digital Tv offers more choice, it is clearer and it can be recieved in many new ways.
How is it a part of our multimedia world?
Digital Televisions are part of the multimedia world because televisions use a variety of different media. This includes true digital and high definition image and surround sound audio.
Are there different types? Advantages/Disadvantages?
There are many different types of digital televisions. The first and most basic type is CRT based or a 'Tube' digital television. These look a lot like analog televisions with a larger screen. If you want to get the most out of the digital television features, such as High Definition television and surround-sound audio, another type would be Plasma televisions. Plasma televisions are very thin, large and look terrific with the sound even better. A third type of digital television is a Rear Projection television. In these televisions the image would come from the back of the tv, meaning it would be thicker with also great high-definition television and surround sound. Another type of television is an LCD television, these televisions have a rich high-definition image and surround sound audio. There is also SD (Standard Definition) televisions which produce a widescreen image with DVD standard quality.
A "simple" explanation of how it works.
Digital Televisions work similarily to a standard television set. Depending on what type of television it is, the way in which it works has little difference. Digital televisions all work mainly the same way, but with a different appearance. Digital television uses a digital signal rather than a radio signal, which allows the picture and sound to appear faster and with better quality. In order get your digital television working, you need to get the satellite cable that connects your tv to the digital signal. The satellite cable is plugged into the tv port and your television is ready to go. Depending on signal strength, you picture will come clearer, faster and in good quality.
A rough indication of the cost of the device
The cost of a Digital televisions depends on what you are looking for. Smaller screen resolution televisions cost from $700-$1000. Larger Plasma televisions cost $2000-$2500 and LCD televisions cost $2500-$3000. 3DTV's are much more expensive depending on whether you buy Plasma or LCD Plasma 3DTV's range from $4500-$5500 and LCD 3DTV's cost $5000+.
Future directions, what is waiting around the corner, what is the next "new" technology in this area?
Panasonic plans to develop televisions that enable viewers to browse the Internet with the simple operation of an easy-to-use remote controller. Stepping out more than 10-15 years into the future, visitors to the Panasonic Center can also experience its Digital Wall. Composed of a large grid of touch-sensitive panels, the wall has tiles to display different applications or to project one larger-than-life video image.

Hand-held Computing
http://www.engadget.com/2008/01/10/intel-explains-mid-vs-umpc/
http://www.umpcportal.com/products/
1. What are MID & UMPC devices? How do they differ. List atleast three examples of both types of devices & include images.
An MID is a mobile internet device and a UMPC is the ultra mobile portable computer. The difference between both devices is that the UMPC is a business-class device thats for enterprise users and the MID is a consumer-class lifestyle device. The UMPC runs a "heavy" OS (Operating System) like Vista and the MID runs a "lightweight" OS with a fast startup such as Linux. The UMPC is optimized for office-use things like Excel or Word, whereas the MID is for media playback and websurfing.
Examples of MID: Dell Streak, Archos 5 Internet Table & Huawei Smakit S7
Examples of UMPC: Viliv N5, Archos 9 & Sony Vaio
Watch this video http://www.youtube.com/watch?v=NQgiZd0-DxI&feature=related
and answer the following question:
2. What are the differences between a Notebook handheld computing device and a Netbook handheld computing device?
The screen size of a Netbook would usually be around 7", 9" & 10" but a Notebook's size would be 12.1", 13.1", 13.3", 14.1", 15.4" & 17". The size difference is obvious so the Netbook would be much smaller. But you still get some tradeoff's. Power, Memory and Storage.
The Notebook is running with Vista and it can run XP it has a dual core processor with a large regular hardrive and it can have up to 80 to 320 GB worth of storgae space onboard. The Netbooks usually have very a small storage space, usually 4 to 80 GB sometimes even bigger. The Netbook wouldn't be a place to store a lot of movies or videos maybe only a few pictures, songs because you can play music on it. It wouldn't be a place to put on games or applications, there won't be Photoshop or Word or Excel. The whole point of it is the Net-Centric Computing. For example, sufing the web, checking your email and running web applications. You shouldn't run complex programs on this because it wil run very slowly because of the processor, it has an Intel Atom 1.6GHz (very small and does the basic stuff).
A notebook can do everything a normal computer would do and includes a DVD disk drive. The netbook battery life lasts about 3 to 4 hours and the Notebooks waste their power much more quickly and will only go for about 2 to 4 hours. With Netbooks you can ungrade the batteries which give you 6 to 10 hours of battery life.
3. Using the following sites, describe the design & features of the Apple Ipad then discuss how it compares with a Netbook.
http://www.apple.com/ipad/
http://www.youtube.com/watch?v=MoMo4BcvPbA
With the Ipad there are no usb ports so you can't plug in usb's or other things with a usb cord. However the Ipad has many other features that a Netbook won't have such as applications and very small weight. It also has more storage space included in it.
The ipad has no webcam, no multitasking and no HDMI port and no flash. It is called a purpose filled device, it can watch videos very well and web browsing. The internet speed is much faster and is there to surprise you.
4. Of the three handheld devices - Notebook, netbook & Ipad – which one would suit your needs and why?
5. If I was looking for a UMPC device with a screen size of 10 in or less, which would you recommend? Justify your choice.
6. View some of the videos at this link http://www.umpcportal.com/
How would you envisage students five years from now using one of these devices at school. Select any UMPC / MID device that you have researched that would meet a students needs, justify your choice.
Bits & Bytes
A digit is the 1 or 0 in a bit.
2. “normal” counting numbers used in everyday life a based on what sequence of numbers?
0 to 9 ten does not count since its made up of two existent numbers
3. Where does the word bit originate from?
4. Binary numbers don’t use base 10. What base do they use? What digits are available in base 2?
They all count in two's
5. If 6,357 can be written as;
(6 * 1000) + (3 * 100) + (5 * 10) + (7 * 1) = 6000 + 300 + 50 + 7
How would you write 4,321
(4*1000) + (3*100) + (2*10) + (1*1) = 4000 +300+20+1
6.Write the following numbers in binary (base 2)
21 = 101000
24 = 101000
30= 1010000
7. What is a byte?
8. How many bytes in a kilo, mega, giga and tera bytes.
9. Complete the following conversions;
1000 Mb = 1Gb
500 Gb = 5000Mb
5000 Kb = 5 Mb

The CPU
http://www.intel.com/technology/atom/index.htm
1. What is the function of the CPU?
This is where all computations are carried out before being transferred to memory storage. The CPU accepts input data, processes the information and sends it to the component that is in charge of executing the action.
The CPU, or Central Processing Unit, is the brains of the computer. This is where all the processing of data, computations, and operations are done. The CPU contains the memory, the hard drives, and ports as well that connect all the computer parts and allow each one to function. Without the CPU, one would not be able to do anything with the computer. 2. What was the name of the first CPU?
The first microprocessor to make it into a home computer was the Intel 8080, a complete 8-bit computer on one chip, introduced in 1974.
3. Referring to the graph on page 2 of the article, describe how the speed of CPU’s has changed.
From the table you can see that the speeds of the CPU's have increased everytime a new CPU has been created. From the first CPU called the 8080 it had a clock speed of 2 MHz and the number of MIPS was only 0.64, to the most recent CPU it's called Pentium 4 "Prescott" it has a clock speed of 3.6 GHz and the number of MIPS is more than 7000. From these results you can see that there has been a large change from the first one ever to the most recent.
4. What does MIPS measure?
MIPS stands for "millions of instructions per second" and is a rough measure of the performance of a CPU. Modern CPUs can do so many different things that MIPS ratings lose a lot of their meaning, but you can get a general sense of the relative power of the CPUs from this column. Modern processors can often execute at a rate of two instructions per clock cycle. That improvement is directly related to the number of transistors on the chip and will make more sense in the next section.
5. Research (Google it) what is a dual core processor, what is multitasking and how do the two work together.
A Dual Core Processor is a multi-core processor is a processing system composed of two or more independent cores. It can be described as an integrated circuit to which two or more individual processors have been attached.
Multitasking is the simultaneous execution of multiple tasks (programs) under the control of an interrupt-driven operating system.
Dual-core processors contain two processing cores, residing on one chip, that perform calculations on two streams of data to increase efficiency and speed while running multiple programs and the new generation of multi-threaded software. For end-users this means a significant increase in response and performance when running multiple applications simultaneously. True multitasking allows users to switch from one program to another without always pausing for the computer to catch up and reducing annoying processing pauses.

Scanned Storyboard
Some of the frames used in this storyboard isn't same ones as we used in the actual filming so this would still be a draft of the storyboard.
Video Assesment Task 3
Video Assessment Task 2
On the long weekend our group thought of meeting up at vera's house (because she had the camera) and finalize the script so we could continue filming. Me and sangeeta were given the job to do the script while rowena and vera were supposed to do the storyboard. We aimed to mainly focus on our filming rather than the script and storyboard. We also decided to change our plan of how to do make-up to how to play basketball because collecting all the props for the make-up idea would be too much of a hassle. I knew most of the basics for basketball but we also did some reaserch to back up these rules. After meeting up at vera's house for a short while, we wrote most of the script and vera & rowena's jobs are still mainly the same but i was the one to complete the final draft of the script and write it out. We would hope to film next week and get it all done in one day because we didn't like the idea of having to wear the same clothes and film at the same area more every single time. We will have the script & storyboard done by next week so we can commence filming :D

Rules for Basketball
RULES:
• Two teams of five players each try to score by shooting a ball through a hoop elevated 10ft above the ground. The game is played on a rectangular floor called the court, and there is a hoop at each end. The court is divided into two main sections by the mid-court line.
• If the offensive team puts the ball into play behind the mid-court line, it has ten seconds to get the ball over the mid-court line. If it doesn't, then the defence gets the ball.
• Once the offensive team gets the ball over the mid-court line, it can no longer have possession of the ball in the area in back of the line. If it does, the defence is awarded the ball.
• The team with the ball is called the offense. The team without the ball is called the defence. They try to steal the ball, contest shots, steal and deflect passes, and garner rebounds.
• When a team makes a basket, they score two points and the ball goes to the other team. If a basket, or field goal, is made outside of the three-point arc, then that basket is worth three points. A free throw is worth one point. Free throws are awarded to a team according to some formats involving the number of fouls committed in a half and/or the type of foul committed.
• Each game is divided into sections. All levels have two halves. In high school and below, the halves are divided into eight (and sometimes, six) minute quarters.
• Each team is assigned a basket or goal to defend. This means that the other basket is their scoring basket. At halftime, the teams switch goals. The game begins with one player from either team at centre court. A referee will toss the ball up between the two. The player that gets hands on the ball will tip it to a teammate. This is called a tip-off. In addition to stealing the ball from an opposing player, there are other ways for a team to get the ball.
FOULS:
o Personal fouls: Personal fouls include any type of illegal physical contact.
• Hitting
• Pushing
• Slapping
• Holding
• Illegal pick/screen -- when an offensive player is moving. When an offensive player sticks out a limb and makes physical contact with a defender in an attempt to block the path of the defender.
o Personal foul penalties: If a player is shooting while a being fouled, then he gets two free throws if his shot doesn't go in, but only one free throw if his shot does go in.
One & one. If the team committing the foul has seven or more fouls in the game, then the player who was fouled is awarded one free throw. If he makes his first shot, then he is awarded another free throw.
Ten or more fouls. If the team committing the foul has ten or more fouls, then the fouled player receives two free throws.
o Charging. An offensive foul that is committed when a player pushes or runs over a defensive player. The ball is given to the team that the foul was committed upon.
o Blocking. Blocking is illegal personal contact resulting from a defender not establishing position in time to prevent an opponent's drive to the basket.
o Flagrant foul. Violent contact with an opponent. This includes hitting, kicking, and punching. This type of foul results in free throws plus the offense retaining possession of the ball after the free throws.
o Intentional foul. When a player makes physical contact with another player with no reasonable effort to steal the ball. It is a judgment call for the officials.
o Technical foul. Technical foul. A player or a coach can commit this type of foul. It does not involve player contact or the ball but is instead about the 'manners' of the game. Foul language, obscenity, obscene gestures, and even arguing can be considered a technical foul, as can technical details regarding filling in the scorebook improperly or dunking during warm-ups.
VIOLATIONS:
Walking/Travelling. Taking more than 'a step and a half' without dribbling the ball is travelling. Moving your pivot foot once you've stopped dribbling is travelling.
Carrying/palming. When a player dribbles the ball with his hand too far to the side of or, sometimes, even under the ball.
Double Dribble. Dribbling the ball with both hands on the ball at the same time or picking up the dribble and then dribbling again is a double dribble.
Held ball. Occasionally, two or more opposing players will gain possession of the ball at the same time. In order to avoid a prolonged and/or violent tussle, the referee stops the action and awards the ball to one team or the other on a rotating basis.
Goaltending. If a defensive player interferes with a shot while it's on the way down toward the basket, while it's on the way up toward the basket after having touched the backboard, or while it's in the cylinder above the rim, it's goaltending and the shot counts. If committed by an offensive player, it's a violation.
Backcourt violation. Once the offense has brought the ball across the mid-court line, they cannot go back across the line during possession. If they do, the ball is awarded to the other team to pass inbounds.
Time restrictions. A player passing the ball inbounds has five seconds to pass the ball. If he does not, then the ball is awarded to the other team. Other time restrictions include the rule that a player cannot have the ball for more than five seconds when being closely guarded and, in some states and levels, shot-clock restrictions requiring a team to attempt a shot within a given time frame.
PLAYER POSITIONS:
Centre. Centres are generally your tallest players. They generally are positioned near the basket.
Offensive -- The centre’s goal is to get open for a pass and to shoot. They are also responsible for blocking defenders, known as picking or screening, to open other players up for driving to the basket for a goal. Centres are expected to get some offensive rebounds and put-backs.
Defensive -- On defence, the centre’s main responsibility is to keep opponents from shooting by blocking shots and passes in the key area. They also are expected to get a lot of rebounds because they're taller.
Forward. Your next tallest players will most likely be your forwards. While a forward may be called upon to play under the hoop, they may also be required to operate in the wings and corner areas.
Offensive -- Forwards are responsible to get free for a pass, take outside shots, drive for goals, and rebound.
Defensive -- Responsibilities include preventing drives to the goal and rebounding.
Guard. These are potentially your shortest players and they should be really good at dribbling fast, seeing the court, and passing. It is their job to bring the ball down the court and set up offensive plays.
Offensive -- Dribbling, passing, and setting up offensive plays are a guard's main responsibilities. They also need to be able to drive to the basket and to shoot from the perimeter.
Defensive -- On defence, a guard is responsible for stealing passes, contesting shots, preventing drives to the hoop, and for boxing out.
