A: NOT means inversion of the function like an OR gate if inverted it becomes a NOR gate AND becomes a NAND gate if logic input function is inverted on the output. This can plainly be seen by looking at a gate symbol if there is a circle on the output it means it function is inverted.
B: You have not answered my question, please read carefully my question again!
You can make an AND gate out of NOR gates, but you can't make one out of regular OR gates and nothing else.
universal logic gate is a gate using which you can make all the logic gates there are two such gates NOR gate and NAND gate
The two categories for logic gates are basic logic gates and universal gates. Gates are identified by their function and universal gates are identified as NAND gate or NOR gate.
A universal gate is a gate which can implement any Boolean function without need touse any other gate type.The NAND and NOR gates are universal gates.In practice, this is advantageous since NAND and NOR gates are economical andeasier to fabricate and are the basic gates used in all IC digital logic families.In fact, an AND gate is typically implemented as a NAND gate followed by aninverter not the other way around!!Likewise, an OR gate is typically implemented as a NOR gate followed by an inverternot the other way around!!A universal gate is a gate which can implement any Boolean function without need touse any other gate type.The NAND and NOR gates are universal gates.In practice, this is advantageous since NAND and NOR gates are economical andeasier to fabricate and are the basic gates used in all IC digital logic families.In fact, an AND gate is typically implemented as a NAND gate followed by aninverter not the other way around!!Likewise, an OR gate is typically implemented as a NOR gate followed by an inverternot the other way around!!can be combined to produce AND, OR,NOT,XORand XNOR gates
No. The city gates are called: # Damascus Gate # Herod's Gate # Lions' Gate # Dung Gate # Zion Gate # Jaffa Gate # Golden Gate - Sealed gates # Single Gate - Sealed gates # Double Gate - Sealed gates # Huldah Gates - Sealed gates See http://www.answers.com/topic/old-city-jerusalem for reasons for the names. The twelve tribes are # Reuben # Simeon # Levi # Judah # Dan # Naphtali # Gad # Asher # Issachar # Zebulun # Joseph # Benjamin Read about them on http://www.answers.com/topic/israelites-2
universal gates are the ones from which we can design other gates also. for eg. NAND and NOR gates. they help in forming the uniformity in the circuits.

an AND gate and a NOT gate
Any logic gate from which all other logic gate functions can be derived. The two universal gates are NAND and NOR.
yes, other type of gates like flap gate,automatic gate,radial gate,fixed wheel type vertical gate are used as sluice gates.
A universal gate is a logic gate that can be used to implement any logic function. The NAND gate and NOR gate are examples of universal gates because any other logic gate can be constructed using only NAND or only NOR gates.
