TTL or time to live
it has two meanings based on the reference of things
if we are considering the Internet and a web site
then it is the amount of time the Internet explorer can keep a page in memory without having to check for updates for e.g. if its 4 hrs
then after 4 hrs that particular page has to be updated
if it is considered with respect to ip protocols and other such protocols in a router design
then it is the no of hops a particular path consists of.
as in from one router to the next how many routers are there in its path to the destination network
for e.g. rip had a hop count of 15
broadcast packets have a hop count of 1
this is decremented at every router or hop
