when the two inputs are shorted, a NAND gate acts like a NOT gate. hence AND = NAND + NOT For OR gate, inverse both the inputs before connecting them to a NAND gate. So three NAND gates would be needed.
The XOR gate (sometimes EOR gate, or EXOR gate) is a digital logic gate that implements an exclusive or; that is, a true output (1) results if one, and only one, of the inputs to the gate is true (1). If both inputs are false (0) or both are true (1), a false output (0) results. Its behavior is summarized in the truth table shown on the right. A way to remember XOR is "one or the other but not both". It represents the inequality function, i.e., the output is HIGH (1) if the inputs are not alike otherwise the output is LOW (0).

The surname Nand-Lal originates from India, they immigrated to Trinidad apparently to help in the cotton fields. Family history has it that one of the Nand-lal brothers became a banker and then wealthy land owner and sent his sons to University in the UK, one was an Engineer, another a Doctor, and it is believed that the other was an Accountant. The brother Raman who was sent to the UK to study medicine first went to Edinburgh University an then to Birmingham to finish his studies... it was too cold for him in Edinburgh. You will find a few Nand-lal or Nand surnames in the UK as the -lal was dropped by some due to complications with UK people understanding the nature of the spelling.

The suffix -gate derives from the Watergate scandal of the United States in the early 1970s, which resulted in the resignation of U.S. President Richard Nixon. Note that Watergate itself does not meet the -gate construction rule, as the scandal was named after the Watergate complex in Washington, D.C.; the complex itself was named after the "Water Gate" area where symphony orchestra concerts were staged on the Potomac River between 1935 and 1965
the not gate applied to and gate is nand gate
A nand gate can be made from an and gate by introducing an inverter at the output of the gate.
74ls00 is the ic no. Of nand gate
nand gate
Connect the two inputs of the NAND gate together.
A: A AND gate becomes a NAND when the output is merely negated or inverted
When the two input terminals of a NAND gate are short circuited, it acts as a NOT gate.
pass the inputs through an nand gate and again pass them through inverter,which is again formed by an nand gate

The TTL Nand gate is usually used in the design of various electric circuits.
