Here are the main functions of an operating system:
1) Manage the resources of the device
The operating system controls how much of each resource is distributed, and it controls things like the processing unit and memory.
2) Establish a interface for the user of the device
The operating system must classify what the classes of the script/code have to do and what they implement.
3) Service application software
The operating system must service each application that is downloaded onto the device. It must balance it's use of storage between apps.
Straw man
eg. "Senator Jones says that we should not fund the attack submarine program. I disagree entirely. I can't understand why he wants to leave us defenseless like that."
Ad hominem
eg. “How can you argue your case for vegetarianism when you are enjoying your steak?”
Over simplication
eg. President Bush wants our country to trade with Fidel Castro's Communist Cuba. I say there should be a trade embargo against Cuba. The issue in our election is Cuban trade, and if you are against it, then you should vote for me for president.
Bandwagon
eg. Everyone is selfish; everyone is doing what he believes will make himself happier. The recognition of that can take most of the sting out of accusations that you're being "selfish." Why should you feel guilty for seeking your own happiness when that's what everyone else is doing, too?
Black or white
eg. Well, it's time for a decision. Will you contribute $20 to our environmental fund, or are you on the side of environmental destruction?
