Nota:

• HDMI stands for High Defenition Multi Media. It sends 1's and 0's to the screen.

Nota:

• It works by using Fits's law which is: T=a+b*log2 (A)                                        (-+)                                      (W)

Nota:

• Let's take a look at the inner workings of the common single-lens reflex (SLR) camera. A camera basically consists of a lightproof box that lets in a bit of light at just the right moment. Once the light enters th amera, it creates an image by causing a chemical reaction on photo film.

Nota:

• It works by using binary code.

Nota:

• A camera works by using different lenses to zoom.  Also it uses light. To show the colour it uses the main three which is green blue and red.

Nota:

• Before the development of high-definition televisions, most TVs displayed pictures in what is now known as standard definition.The picture was roughly square -- its aspect ratio was 4:3. Its resolution, or the number of dots that make up the picture on the screen, was about 704 x 480 pixels. The picture was interlaced -- each piece of the moving image was really half a picture, but the pictures changed quickly enough that the human brain didn't really notice. Finally, older TVs relied on analog signals, which travel as a constantly varying electrical current.
