A logic gate is a computer circuit with several inputs but only one output that can be activated by a particular combinations of inputs, a diagram that shows the major gates can be found here.
An example would be if you have 2 wires going to an AND gate and only 1 wire has a current (is on, 1) and the other one is 0, then your output would be 0 as you need wire 1 AND wire 2 to have a current, for the output to be 1, on.
A sampling gate, on the other hand is a circuit that produces an output only when first activated by a preliminary pulse. So if you have a current going through a wire and through a sampling gate, your output would be 0, unless you program the sampling gate to let the current through.
I'm sorry if this is a slightly plain answer, but if you would like more reading, then go to the Wikipedia.
Logic gates are the basic building blocks of digital circuits or systems. these digital circuits are used to implement several combinational and sequential operations. these operations include starage, timing, arithmetic, coding, communication etc. Hence, implementing the boolean algebra is not the only purpose where logic gates are used, hence, it is opt to call them as logic gates rather than boolean gates.
yes we can short
They can be used for error checking. If the transmitter is off frequency, the logic gates can be used to inhibit the transmitter, to stop interference. Early forms of PLL (Phase Locked Loop) control may also use logic gates to act as dividers. This is normally taken care of by a single dedicated chip, these days.
That title of "Universal Gate" is reserved for NAND gates because you can build all possible logic using only NAND logic . You can build even other basic logic like AND, OR and NOT using NAND.
simply , it is used to control the circuit , for example if i have a lamp ( or LED) and i want to control when it should be on i used sequential logic gate ( or flip-flop ) with an exact input ( say '11' ) . ANSWER: There are no sequential logic gates. But there decoders and multiplexers whereby an output can occurs only when reaching a code or an address
Answering "What is differences between pld and mixed logic gatessuch as the 7400 7432 ic logic device name one pld device?"
A: There is definitely a pin difference in configuration for each family of gates up to a point because of variety of gates available.
limitations of logic gates
types of optical logic gates
logic gates comes under semiconductor
All digital electronic circuits are composed of logic gates. Without logic gates there would be no digital electronics.
And, OR and Not gates.

i need to understand the meaning of latch as applied in logic gates [digital ectronics]
Difference between Propositonal and Predicate logic
state the differences between PAL and the mixed logic gates, such as the 7400, 7432 ic logic devices?
