Why can an SR latch not store values, but a D latch can?
An SR latch cannot store values because it is sensitive to the inputs being constantly changing. This can lead to unpredictable behavior and the inability to hold a stable state. On the other hand, a D latch can store values because it has a single data input that controls when the latch is updated. This allows for a more controlled and stable storage of data.

Why can I store data with a D-latch, but not with an SR-latch? I can also set a bit with S in an SR-latch. So why do I need a D-latch?
You can store data with a D-latch because it has a single data input (D) that allows you to directly input the desired data. On the other hand, an SR-latch does not have a dedicated data input, and instead relies on the S and R inputs to set or reset the latch. While you can set a bit with the S input in an SR-latch, it does not provide a straightforward way to directly input and store data. Therefore, a D-latch is necessary when you want to store data without the need for additional control inputs.

To what extent is a value stored in an SR latch, D latch, and D flip-flop?
In an SR latch, a value is stored in the form of two stable states, either a set state or a reset state. In a D latch, a value is stored based on the input data signal, which is latched and held until the latch is updated. In a D flip-flop, a value is stored based on the clock signal, where the input data is latched and transferred to the output only on the rising or falling edge of the clock signal.
