I run a small business and had 2 computers in my office. I used one computer to do all the office work like keeping record & data, letters etc and the other which is connected to internet for email, research, etc. Both computers are sharing same printer. If the computer that connected to internet get attacked by a virus, does my other computer will be attacked too?

I had two computers both connected to a wireless router. Yesterday I connected a third computer to the network and, although the connection goes through for this new computer, one of the original computers now says “Limited or no connectivity” and cannot connect to the Internet. Is it possible that the new computer is using up too much bandwidth and is therefore preventing the other computer from accessing the Internet?

What was the economic importance of Computers? especially in the 90s. Was it because it expanded the market or what b/c i’m not exactly sure. Pwease helppp mee?
