How does a SR flip flop work?

A basic NAND gate SR flip-flop circuit provides feedback from both of its outputs back to its opposing inputs and is commonly used in memory circuits to store a single data bit. Then the SR flip-flop actually has three inputs, Set, Reset and its current output Q relating to it's current state or history.
A.

Why is it called a flip flop?

All you need to do to figure out why we call them "flip-flops" is to walk around in a pair of them for just a little while. Because of how they're made, the rubber soles slap against the bottom of your feet as you walk, making a flip-flop, flip-flop sound.
• What were flip flops originally called?

In the very late 70s my family moved to Seattle and there they were also called "Thongs". I only became aware of the term "flip-flops" in the late 80s and found it humorous that a g-string would be called a "thong".

Because of how they're made, the rubber soles slap against the bottom of your feet as you walk, making a flip-flop, flip-flop sound. They're "thongs" in Australia and "plakkies" in South Africa.
• What is a thong in Australia?

Footwear. The name thong was also the original name for this footwear in the U.S. but the name flip flop later came to dominate and the term thong in the U.S. now more commonly refers to G-string style underwear.
B.

Is RS flip flop and SR flip flop same?

They are theoretically the same. However, there is a significant practical difference. Recall from the truth table of an SR flip-flop that its state is indeterminate when both inputs at R and S are high. In RS flip-flop, the reset input has higher priority and in an SR flip-flop, the set input has a higher priority.
• What is the difference between JK flip flop and SR flip flop?

The main difference between a JK flip-flop and an SR flip-flop is that in the JK flip-flop, both inputs can be HIGH. When both the J and K inputs are HIGH, the Q output is toggled, which means that the output alternates between HIGH and LOW. Thereby the invalid condition which occurs in the SR flipflop is eliminated.
• What is the SR flip flop?

An SR Flip Flop is an arrangement of logic gates that maintains a stable output even after the inputs are turned off. This simple flip flop circuit has a set input (S) and a reset input (R). The set input causes the output of 0 (top output) and 1 (bottom output).
• How does the D flip flop work?

The D flip-flop tracks the input, making transitions with match those of the input D. The D stands for "data"; this flip-flop stores the value that is on the data line. It can be thought of as a basic memory cell. A D flip-flop can be made from a set/reset flip-flop by tying the set to the reset through an inverter.
C.

What is the difference between a JK flip flop and an SR flip flop?

The main difference between a JK flip-flop and an SR flip-flop is that in the JK flip-flop, both inputs can be HIGH. When both the J and K inputs are HIGH, the Q output is toggled, which means that the output alternates between HIGH and LOW. Thereby the invalid condition which occurs in the SR flipflop is eliminated.
• What is the definition of half adder?

The half adder is an example of a simple, functional digital circuit built from two logic gates. The half adder adds two one-bit binary numbers (AB). The output is the sum of the two bits (S) and the carry (C). Note how the same two inputs are directed to two different gates.
• What is the use of a shift register?

When a bit is input on the right, all the bits move one place to the left, and the leftmost bit disappears. Shift registers are commonly used in converters that translate parallel data to serial data, or vice-versa. Shift registers can also function as delay circuits and digital pulse extenders.
• What is characteristic table of flip flops?

The characteristic table in the third column of Table 1 defines the state of each flip-flop as a function of its inputs and previous state. Q refers to the present state and Q(next) refers to the next state after the occurrence of the clock pulse. When S=1, the flip-flop output Q is set to 1.
