difference between pin pads and numeric keypad
adv and disadv for both???

They are two different things.

- The credit card is inserted into the chip reader
- Card is checked for validity
- If card is valid, transaction approved
- If card is illegimitate or reported stolen, transaction refused
- Customer is prompted to insert PIN
- If the inserted PIN matches the PIN on the card, transaction approved
- If the inserted PIn does not correspond with the PIN on the card, transaction refused
Do not go where the path may lead. Go instead where there is no path and leave a trail.

We studied this:
What is multimedia?
The main ways that the computer can feed the user's senses is through the use of:
colour
motion of areas of the screen as appropriate
a range of standard shape tools such as rectangles and circles
sound
motion through the use of motors
Games on computers first started out without any sound at all, and many people thought that the inclusion of sound to a game would not make much difference. In fact it was soon found that adding even simple sounds enhanced the overall experience of the computer user.
The use of multimedia also allows the possibility of user input to make selections and choices. This is called interactive multimedia, because the user interacts with the material in some way.

Examples of multimedia
If you send a CD of digital photos of your party to a friend, and you add some sound clips, you are preparing a multimedia presentation because you are using more than one type of media.
Video is a good example of multimedia in that it uses colour, onscreen motion and sound. However on a computer it can also have the user interact with the material eg:
stop the display
go to various places on the video
answer questions that are posed
select from various options that are presented by the interactive package
an educational type of package can ask for help or extra information
A virtual reality application - eg a cockpit simulator that's used to train pilots on the ground - is an example of multimedia. In a virtual reality simulator the pilot, though not actually in the plane, feels as though he/she is.
A wide range of multimedia programmes are available on other formats, for example, educational training packages to learn a foreign language or a CD ROM/DVD encyclopaedia.

I've got a bit more on that if you need it

Knowing what they are.
And a bit more detail on multimedia presentations
When comparing multimedia presentations to desktop publishing, include the followings :

- Can add video / animations
- Can add audio

Multimedia and the Internet
The Internet is a massive source of multimedia content. By this we mean that we can access various sorts of media. These include:
sound - e.g. MP3 files. MP3 is an short form for MPEG layer 3.It is the standard format for compressing a sound sequence into a very small file, up to 12 times smaller. The good thing about MP3 is that there is no or very little loss of sound quality from the original file.
still digital pictures
moving digital pictures or "streaming video" such as DVD downloads to play on the computer
Multimedia sites that combine text, graphics and sound to display on your computer such as revision websites with video and audio clips, games and written tests.
What you need for multimedia
In order for a computer to cope with multimedia, it needs to fulfil certain requirements:
It needs to be powerful enough to display the presentation e.g. a palmtop needs a powerful enough processor to display pictures on its screen and be able to play good quality sound.
A pc needs a reasonable graphics (video) card.
A pc needs a lot of memory - both RAM and hard drive space.
A method of producing reasonable sound (sound card plus speakers on a pc) is needed.
An output interface is needed if motion is to be used e.g. force feedback motion on joysticks to make them shake in games.
Appropriate software to run the presentation is needed eg software that will display the video and sound files properly



Good Luck you guys
Don't freak over ICT.
Just get a good nights sleep
And don't forget to practice past papers

Firewall is a piece of hardware which prevents unauthorised access to a computer system or a computer network .. it 'filters' data passing through it and sends in only the 'good' data .. hacking can be preventing by using a firewall ..

There won't be any changes to the format this year.
But about the wording of the question, it'll change obviously lol ;).
