2. Output
2.1. Example: Printers ( inkjet and laserjet)
2.1.1. Pro: a printer allows you to produce a "hard copy" of the information that you entered into the computer. You can print as many copies as you like, and you can have it in color and/or black and white. Students may find it rather rewarding to see their hard work in their hands.
2.1.2. Con: the down side to printers in the cost of supplies. Inkjets run off of ink cartridges, which cost about $20-$30 each.Laser jets run use "toner" which costs at least $40 each. Printer paper can be cheap, or it can be expensive. It all depends on the quality of the paper you are looking for.
