Why are tall transmission towers painted white and red?
So airplanes don't crash into them.
Answer red/white towersIt has to do with color. Blue at a distance looks black, green blends in with the background, etc., but white and red can be seen at long distances, hence are good warning colors for the towers. By the way, why do you suppose many tribal carpets have red as the dominant color? After the brightness of desert, coming into a tent or home spread with reddish carpets relaxes the eyes.Also those colors are used to know the height of the tower, 10ft per colorIs there any software to allow a computer to act as a DSL modem?

If you use an adsl modem and connected to two computer is your ip same on both computers?
No, each computer must have a different IP address. The IP addresses have to be in the same subnet between themselves, and in the same subnet as the ADSL router (or modem); I won't explain subnets here, but usually having the same numbers for the first 3 parts of the IP address is enough. For example, if the ADSL router has the IP address 10.0.0.1, your computers might have addresses 10.0.0.2 and 10.0.0.3. If you need to add a third computer, give it the IP address 10.0.0.4
If the first computer has a different IP address - and it works - replace that, instead. For example, if the computer has IP address 172.16.0.2, assign the address 172.16.0.3 to the next computer.
