VLSI. (Very large scale integration)
Their application is for logic control. The output is dependant on various inputs. They can be arranged, to hard wire a fixed response for any number of inputs.
They can act at very high speed so can analyse wave forms and clock signals for digital signal processing.
At a basic level they can be used to determine that safety locks are in place before operation a piece of machinery.
They can also be used to strip synchronising pulses from a wave form.

3) in pnp, npn trasisters
Everything digital! The basic logic gates are AND, OR, and NOT. (Sometimes they are combined.) These basic gates are combined into larger components like arithmetic adders, multiplexers, and some kinds of memories. Those components are combined into yet larger components like computers, which are in turn put into still larger components like internet routers, digital television sets, your cell phone, tablet, Blue Ray player, or iPad. At the bottom of everything digital you own or use are the AND, OR, and NOT gates. Thousands and millions of them, connected in lots of different ways to build the digital devices you use everyday.
All these combinations presents us with 'results' and 'conclusions'.
Thus in the same manner that we 'arrive' and reach a 'point' we have always to push something backwards. We tend to push back to come forward. We might not notice it that when we walk we use our feet to push the ground back, a space shuttle moves away by putting a thrust on something else, when there might not be anything it detaches a part from its envoy and push against it. A boat has a propeller which moves the sea back in order to get ahead towards a destination. Electricity overcome a negative element in order to convey positive energy towards our appliances.
All these actions are a 'feature' of existence upon which we arrive towards a pole position over things that we put behind us.
An XNOR gate is a logic gate performing a Boolean logic XNOR operation, also known as an equivalence gate.
AND
INVERTER gate
the pullup or pull down resistance in the diode logic gate makes it a high output resistance device.If u try to drive another diode logic gate with it the output voltage of the first gate will be affected by the resistance in the second gate.A diode logic gate should always drive a high input resistance input.
A logic gate composed only of diodes and resistors. The only types are AND gates and OR gates. However the number of layers of logic that can be implemented are severely limited due to losses in these gates.
An AND gate is a logic gate performing a Boolean logic AND operation.
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
An XNOR gate is a logic gate performing a Boolean logic XNOR operation, also known as an equivalence gate.
When the two input terminals of a NAND gate are short circuited, it acts as a NOT gate.
The switching time (on and off) of the TTL logic gate is very fast in comparison with CMOS logic gate. However, they could not tolerate higher range of power supply.
AND gate is an all or nothing gate because in able to have an output of logic 1,all of the input must be all logic 1 or else the output will be nothing or simply logic 0.
All the inputs of the gate must be set to a logic 1 for the gate to open.
Any logic gate from which all other logic gate functions can be derived. The two universal gates are NAND and NOR.
AOI logic stands for AND OR INVERT logic. AND gate in this logic is formed by two PMOS and two NMOS FETs. Its function is to AND two bits.
Exclusive OR
AND
because some of the logic gate are opened in 0volt
