1 Answer

Answer :

Combinational logic
Sequential logic
The combinational logic circuit consists of logic gate only
Sequential logic circuit consists of combinational logic circuit along with memory for storage of information
It operation depend upon present input and does not required history of inputs
It operation depend upon present input as well as last state of input and output which are stored in memory.
Easy to design due to lack of memory. 
Difficult to design due to presence of memory.
Faster in speed as all inputs are primary inputs are applies simultaneously
Slower in speed because of secondary inputs
E.g. Encoders, decoders, multiplexer, demultiplexer etc
E.g. counters, shift registers flip-flop etc
