browsers

Can anyone help me find out how a browser would go about filling in the 
http:// part of a web address instead of the user having to type it in 
for every web site they want to visit?  I am currently enrolled in an 
internet course and have been given an assignment to find this out and 
write an RFC. Any help would be tremendously appreciated.
