Depends on what ports you open, and what kind of internet connection you are running. If you are running a residential internet connection, and you are doing your usual day-to-day things (email, web browsing, youtube) then you should not have an issue opening ports 80, 25, 443 and whatever else you use. Though you should note that if you are doing more dangerous things on your connection (you know who you are ;) ) then you should probably not open these ports as they can be used for malicious things.
25% off of 80:= 25% discount applied to 80= 80 - (25% x 80)= 80 - (0.25 x 80)= 80 - 20= 60
Twenty five percent of a number would be 1/4 of it. So that would have "25% of 80" is as "80/4 = 20".
25% of 80 is 20 !
80% of 25 is 20 80% from 25 is 5
25% of 80 = 80*(25/100) = 20
It is $1.6* * * * *That is just so not true. It appears to have been answered by someone who used a calculator without understanding the question or have a feel for the magnitude of the answer.25% of 80 dollars is 80*25/100 which is 16 dollars, not1.60 dollars.Next, 25% off of 80 dollars is 80 less 16 = 64 dollars.
When two programs on the same computer want to access the internet, they will each use a different port. For example, if you are chatting on AIM and browsing the web at the same time, web traffic will go through port 80 and AIM traffic will go through port 5190. That way when data comes back to the computer, it can be directed either to AIM (if it comes in on 5190) or the web browser (if it comes into port 80). If you are choosing a port manually for some reason, it doesn't usually matter what you choose as long as that port number is not in use by another program. Pick a big random number and you are safe. -DJ Craig
