HOME SCHOOL COMPUTER SMART CARD TELEPHONE PRINTER MICROWAVE PHOTOCOPIER WASHING MACHINE COMPUTER Description HOME Computer: this technology is very powerful as it has a number of software and applications for any type of work, which needs to be done. A computer can also access Internet if you have the right equipment. If connected with a printer it can print data typed out or found also a scanner can send images to the computer to keep or edit. A computer also can be found with different hard drives such as a floppy drive to save or load documents from floppy disks, also hard drives can have CD rewriter which is used for coping CDs or saving songs on a CD. This meets my need by simply doing things faster like writing is longer but on the computer it can be typed out fast also size can be altered and other different ways of creating documents can easier and better than hand drawn or written. ...read more.

* After some time agitating, the washer drains the water and then spins the clothes to remove most of the water. Then, it refills, and agitates the clothes some more to rinse out the soap. Then it drains and spins again. These are also very useful but are very annoying at times such as when whites get mixed with other colours and when something gets stuck it messes up the wholes machine and this cost as well as water is pumped into it. SCHOOL Smart Card: this uses technology where you are electronically registered but these also help you gain points for coming to lessons and with enough points you can apply for gifts such as trips and pens. Every student is given a card which then is stuck into a machine then when the light switches from red to green to can take it out. A smart card - a type of chip card - is a plastic card embedded with a computer chip that stores and transacts data between users. This data is associated with either value or information or both and is stored and processed within the card's chip, either a memory or microprocessor. The card data is transacted via a reader that is part of a computing system. Smart card-enhanced systems are in use today throughout several key applications, including healthcare, banking, entertainment and transportation. To various degrees, all applications can benefit from the added features and security that smart cards provide. Smart cards greatly improve the convenience and security of any transaction. ...read more.

Conclusion

do not reflect light onto the drum, leaving regions of positive charges on the drum's surface. * Negatively charged, dry, black pigment called toner is then spread over the surface of the drum, and the pigment particles adhere to the positive charges that remain. * A positively charged sheet of paper then passes over the surface of the drum, attracting the beads of toner away from it. * The paper is then heated and pressed to fuse the image formed by the toner to the paper's surface. When the copier illuminates the sheet of paper on the glass surface of a copier, a pattern of the image is projected onto the positively charged photoreceptive drum below. Light reflected from blank areas on the page hits the drum and causes the charged particles coating the drum's surface to be neutralized. This leaves positive charges only where there are dark areas on the paper that did not reflect light. These positive charges attract negatively charged toner. The toner is then transferred and fused to a positively charged sheet of paper. Inside a Photocopier If you take a photocopier apart, you might be overwhelmed by how many different parts there are. However, the actual photocopying process relies on only a few, key pieces: * Photoreceptor drum (or belt) * Corona wires * Lamp and lenses * Toner Photocopier are very useful at times because instead of you doing something again and again you can just copy it but sometimes it can become cut out by faults such as not pressing to hard on it.
