Biometrics
- is refers to technologies that measure and analyze human body characteristic such as DNA and fingerprints  

Producers: Apple, 3M Cogent, Access IS etc

Uses...; Authentication purposes and Identification   

1. Airport security
2. building access - finger print
3. cars- voice recognition
4. blood bank-iris recognition
5. school; recording attendance, checking out library books  and paying for meals 
6. Accessing private room; finger print or eye scanner (iris recognition)

Biomatric can make lot of activities easier like; making the teachers signing in the morning easier, when they arrived at school they just put their thumbs to the scanner....and also paying for meals.

This emerging technology might affected some technologies like the number pad lock at the door because they will use the finger print or eye scanner instead.
Biometrics is a good technology. However, they may affect people's everyday lives; it can erase your finger print if you use the machine(sliding) for a long time. Also it can make people lazy because people will use to the easy machine like this, so when it come the situation like people need to write down the registration instead of using finger print, it would be hard for them. 

3D and holographic imaging 

-Holography is a photographic technique that records the light scattered from an object, and then presents it in a way that appears three-dimensional.

Producers: Ford Motor company, Holographic Marketing System P.Ltd, HOLO 3D Srl, (IHMA) etc
Uses.....

1. Bio medical imaging - digital holograms...DNA, human body, cells, full sized organs, etc
2. Car industry and consumers  - 3D car from transparent
3. Movies - Star Wars and Iron Man
4. Rainbow holograms - security purposes...credit card, car licenses etc

Holograms imaging can make the medical system easier because the digital holograms will help to picture the DNA, cells, inside human body and other things else, so the doctors can see the pictures easier and so the patient.

This technology may affect many other technologies such as; projector that used to put pictures up the big screen.

Holographic imaging is a good technology, but they might affect people's everyday lives, many company that sell projectors might need to close down because the hologram coming up instead of them. However, the holograms help the community secure support and funding for development for increasing regional manufacturing in Illinois.

User interface: is a system that allow the user to interact (command) with the computer.
There are 2 types of the user interface:

• Graphical user interface (GUI)
• Command line interface (CLI)

Graphical user interface (GUI)

GUI is quite easy to use due to the visual nature interface, but this type of user interface use up a lot of power, so the computer must be quite powerful.

• Windows - regions of the screen use to display information (operating system e.g window XP)
• Icons - small pictures used to represent folders and software...
• Menus - lists of options that user can select from
• Pointer - arrow that used to select icons or menus or other things and it also can move around the screen

GUI is sometime called WIMP

-Windows

-Icons

-Menus

-Pointer

Command line interface (CLI)

• User will see the black screen 
• Need to type in the commands to make anything happen e.g. To copy a text file called NOTES from a floppy disc to the hard drive the user would have to type:
  > COPY A:\NOTES.TXT C:\
• Need to learn the whole set of commands 
• There is no visual clue to tell you what to do next!?
• It is quite difficult to use

What is inside our computer??

CPU (central processing unit) is the brain of the computer. This is the device that carry out software instructions. 

• It is plug to the main circuit board called the motherboard.
• There is a large fan attached to the CPU to keep the CPU cool.
• The speed of the CPU is measure in Hertz

RAM (Random Access Memory)... part of the computer that temporarily stores the instructions which computer is running and the data processing.

RAM: 

• Volatile storage device, it disappear when the computer is turn off...
• Plug into sockets on the motherboard. 

     -When computer is in use, the RAM contain:

1. Operating system software
2. Application software
3. Data is being processed

ROM (Read Only Memory) is used in most computers to hold a small, special piece of software; the boot up program.

• run when computer is turn on.
• non-volatile storage = the data that ROM contains will never lost, even the power is turn off.
