Answer 1

Latches and flip-flops are the basic elements for storing information. They are made of logic gates.
One latch or flip-flop can store a 1-bit of information.
For latches, its input can affect the output as long as the enable signal is asserted (high).
For flip-flop, its input can affect the output only when the enable signal changes (falling edge or rising edge).

The difference between latches and flip flops is shown

Latches	Flip Flops
Latches are building block of sequential circuits and they are built using logic gates	Flip flops are also building blocks of sequential circuits but they are made using latches
Latches continuously change the input and output changes correspondingly	Flip flop output changes only when the clock is applied
Latches are level sensitive	Flip flops are edge sensitive
