Answer / balaganapathi.m
To explain the concept of port, i use the one example,
You are writing a letter to your friend, in this letter you
will write the Full address details such as Door
Number,Village Name, etc....
Take this example, in networking level, Here the Village
name is like IP address and Door Number is like Port.
Why you are mentioning the door number in the letter,
because in the village there are number of houses, to find
your friends house the Door Number is needed, Like that in
computer there are many process running simultaneously, to
identify particular process, port number is mainly used.
there are totally 65,535 port numbers are available, Some
port numbers are known as well known port number, this is
mainly used as server port number.
