Session
Most technology terms mean
literally what they represent in the English dictionary, well with a
little ketchup. A session is a lease of time that you’d take with a
fellow, or any other entity. Once you are in a
session with the other entity, you can actively use it ; or communicate
with whatever communication mechanism that entity has.
Transaction
A
transaction occurs AFTER a session. Once you are in a session, you
perform transactions. You are in absolute need to be in a session to
perform a transaction. You cannot perform a
transaction with an entity without being in session with it. For example
let’s take an example of a ATM machine.
You
go and stand in queue of waiting customers who wish to acquire a session
with the ATM. Once the ATM is free, you initiate your session. Now you
and the ATM are tunneled, face to face and ready to do business. You
dial your pin, and this is where you start your transaction. So any
material work you perform with an entity will be called a transaction.
So basically the purpose of acquiring a session IS in effect because you
wished to perform a transaction. The transaction is the real action
that full fills the business you have with the other entity.
Making
the other entity aware of yourself is hence called a session, in which
you and the entity have now shaken hands. After that as you work, it’ll
be termed as a transaction.
