A combinational circuit's output depends only on its current inputs. This means, it has a truth table. A sequential circuit's output depends on its previous inputs. This means, it's output will depend on which state it is.

The main difference between sequential circuits and combinational circuits is that sequential circuits compute their output based on input and state, and that the state is updated based on a clock. Combinational logic circuits implement Boolean functions, so they are functions only of their inputs, and are not based on clocks.

Are you asking "How are series circuits different than combination circuits (in electronics) ? A series circuit has one and only one path for electricity to follow; through each component one after the other. A Parallel circuit has a separate path for electricity to follow through each component all at the same time. A combination circuit is both; Put many series circuits all in parallel with each other, that is a combination circuit.
dear friends, the answer for this question. go to www.google.co.in then type sequential circuit having two d flip flops. u can find the answer for the same question at the top of the page itself.
In Nested Logic a Logic is contained within a Logic. If the Outer Logic is TRUE then the internal Logic is executed. Nested IF, Nested For, Nested While, e.t.c are some examples of Nested Logic in Modern Computer Languages.
An adaptive program is one that changes its behavior base on the current state of its environment. This notion of adaptivity is formalized, and a logic for reasoning about adaptive programs is presented. The logic includes several composition operators that can be used to define an adaptive program in terms of given constituent programs; programs resulting from these compositions retain the adaptive properties of their constituent programs. The authors begin by discussing adaptive sequential programs, then extend the discussion to adaptive distributed programs. The relationship between adaptivity and self-stabilization is discussed. A case study for constructing an adaptive distributed program where a token is circulated in a ring of processes is presented.
Hard wired control unit is faster than microprogrammed because it involves the use of combinational circuits to implement control logic whereas microprogrammed uses microprograms for the same purpose.
Computers use binary logic to process information.
