1. CAD and CAM and ICT in Graphics

2. CAD- Means using computer drawing and modelling programmes to design products instead of using paper and pencils CAM- Means the process of manufacturing products with the help of computers. Computer Aided Design Computer Aided Manufacture

3. Advantages of CAD Saved and modified easily Quick to produce drawings both 2D and 3D Reduced or enlarged Common components pre drawn available High quality Accurate Linked to CAM Disadvantages of CAD Expensive Detailed programs need to be learnt Risk of crashing or losing work Examples of CAD ~ Techsoft 2D Design, Pro Desktop

4. Advantages or CAM Production is quicker and efficient Machines do not need to rest like people do Accurate Machines can be run continuously Quick repetition Disadvantages of CAM Expensive Machine replaces peoples jobs Smaller amount of staff need to be highly trained to run machines Examples of CAM ~ Denford microrouter, Vinyl cutter

5. ICT Word processing packages – Microsoft word Spreadsheets - excel DTP – desktop publishing – publisher, photoshop Graphic packages – paint, CAD – techsoft The internet

6. Graphics input devices Barcodes – printed on packaging, read by an optical scanner Keyboard – concept keyboard Graphics tablet – a flat pad on which you use a special pen to draw an accurate image on the screen Scanner – transfer images onto the computer Digital camera – read by a computer

7. Graphics output devices Ink jet printer – cheap to buy, low quality and speed Laser printer – more expensive therefore better quality Plotters – accurate and good quality, used in conjunction with CAD and CAM
