Difference between Buffer and Latch

Latch is something once enabled holds the value for infinite time as
long has it has Vcc and ground connections.

Buffer is something which holds the value for finite time during which
you need to read it. It can essentially be a part of sample and hold
circuit.

Please correct me if I am wrong in defining any of the two devices.

You're wrong. A buffer merely strengthens a aignal so that it can
be fanned out with integrity or drive a heftier device. Any amplifier
is a buffer. It outputs a state only as long as the state persists
on its input(s).

A latch remembers the last state it was told to with another latching
signal.

Or polishes the floors.

Or secures the doors.

A latch means just that it will hold that state until told to release or power down. A buffer is nothing else but a buffer to isolate one signal from its source or recondition it function to be used somewhere else.
