What is an operating system?
Hi Betty,
In school I am taking a class call the Fundamentals of Operating Systems.
If I understand it right an operating system is like Windows Vista. And the operating system is the brain of the computer because it makes everything work together. Example: mouse, keyboard, monitor, and printer. It controls what is put into the computer and what comes out. Like when you strick a key on the keyboard it is the input and then when you see the typing on the screen this is the output.
Does this make any sense to you Betty? Am I understanding what an operating system is and what it does?
I am also taking a Unix class.

Choosing the right cartridge
We've had people come in to buy an ink cartridge and they have no idea what they need; quite often, they don't even know what printer they have - and we have even had people who've bought an ink cartridge only because it was the "right" brand - and then brought it back later because it did not work with their computer. As recently as last week, we had someone bring back an inkjet cartridge because it has "stopped working" - after six weeks printing 31 pages per day. We assume that you know what you need; if you don't know what you need, ask someone to help you.
The purpose of this article is to educate you on buying the right ink cartridge…
Laser or Inkjet? … things to consider when buying a new printer
We get several people coming in asking for recommendations about which printer to buy. Whether you buy inkjet or laser depends on several things. If you are looking for speed, quality, volume, long life of the documents you print, and an overall lower cost of ownership, go with laser. If you print in low volume (10-12 pages per day) or you are looking to print photographic images, choose an inkjet.

A “Zombie” is a computer that is unknowingly being used to transmit SPAM.
Viruses and SPAM go hand in hand. To avoid detection, spammers send their emails from a distributed network of unknown computers. Spammers & Virus Authors get together and you end up with a worm in your email that is sending SPAM to everyone in your address book.
