The Morris Virus
Robert
Morris, a doctoral student at Cornell University, wrote one of the
first computer viruses that spread itself via a network. When released,
the virus would target VAX and Sun machines. Unlike some of today’s
viruses, it was not designed to cause harm to the computer: when a
computer was infected, the virus would duplicate itself every 90
seconds. This caused the computers to eventually slow down or crash as
the number of virus processes running in the background increased.
During this period, the virus would scan for other computers connected
to the network and look for security holes in the OS and networks that
it could bypass to infect another machine. It also used the send mail
protocol to send infected emails from the host computer.
Print Preview While
You're Editing in MS Excel 2007?
Sounds unbelievable - how in the world will we preview the printed version of a worksheet while we edit?
We're all very used to creating our worksheets then going to print preview. The process always seems to hold surprises. It doesn't split from one page to the next in any way we had anticipated the header is so large that it overlaps the worksheet content the list of disappointing surprises could go on for days.

Q:
What does the "End" Key do?
A:
The End key can actually do different things, depending on the program you're using it with. Its main use though is to help you get from the top of a page to the bottom quickly. For example, let's say you're browsing the Internet for some FAQs on a specific topic. You find a great Web site that will help you out, but your question is answered clear at the bottom of the page. Do you sit there and scroll all the way to the bottom? Well, you shouldn't! Instead, use the End key.
