The First PC • The first real PC was the Apple II. It was cheap and was easy to learn how to use. It was factory made and had color graphics. It was created by Steve Jobs and Steve Wozniak.

Virus, Worm, and Trojan Horse • Computer virus’s are small software programs that are designed to spread from one computer to another and interfere with computer operation. • A worm is a reproducing program that runs independently and travels across network connections. Causes harm to the network then. • A trojan horse is a program that pretends to be something its not and spreads viruses throughout your computer. A common Trojan horse would be a program that says it gets rid of virus’s but spreads them.

What We Will Use in the Future • I think what we use in the future will be very advanced and have a lot of memory storage and they will all be touch screen computers with very high speed. Not only that but the computer itself will be very small so no space will be needed to put the computer itself. Like the Mac computer but even smaller.
