SR FLIP-FLOP

The SR Flip-Flop is bistable device having 2 inputs Set and Reset. The Set input (S) sets the device or produces the output 1, and the Reset input (R) resets the device or produces the output 0. 

The Reset input is used to get back the flip flop to its original state from the current state with an output Q. This output depends on the set and reset conditions, which is either at the logic level 0 or 1. 

The NAND Gate SR FLIP-FLOP

We can implement the SR Flip-Flop by using two cross-coupled 2-input NAND gates together. In the SR Flip-Flop, from each output to one of the NAND gate inputs, feedback is connected. So, the device has two inputs, S and R and two outputs Q and Q'.




The NAND Gate SR Flip-Flop is a basic Flip-Flop which provides feedback from both of its output back to its opposing inputs. This circuit is used to store single data bit in the memory circuit.So, the SR Flip-Flop. So, the SR Flip-Flop has three inputs, S , R and the output Q. The output Q is related to the current history or state.

THREE LEVELS OF DATA INDEPENDENCE

THREE LEVELS OF DATA INDEPENDENCE It divides the entire system into three inter-related but independent modules: Physical Level: Here, information about the location of database objects in the data store is kept. Various DBMS users are unaware of the locations of these objects. The Physical level of database describes how the data is stored in secondary storage devices such as disks and tapes. Conceptual Level: Here, data is represented in the form of various tables. For Example, STUDENT database may contain NAME and COURSE tables, but the users are unaware of their storage. It refers to what kind of data to be stored in a database. External Level: Here, it specifies the view of data in terms of conceptual level tables. It can generate different views of the database for different users. It focuses main on data abstraction.  Data Independence: It means change of data at one level must not affect the another level. Physical Data Independence: Any change in the physical location of the t

Python-HackerRank Problem List Comprehensions

Problem Print a list of all possible coordinates given by (i,j,k) on a 3D grid where the sum of i+j+k is not equal to  n. Here, 0<=i<=x;0<=j<=y;0<=k<=z. Please use list comprehensions rather than multiple loops, as a learning exercise.  Source Code   if  __name__ ==  '__main__' :     x =  int ( input ())     y =  int ( input ())     z =  int ( input ())     n =  int ( input ())      print   ([[ a , b , c ]   for  a  in   range ( 0 , x+1 )   for  b  in   range ( 0 , y+1 )   for  c  in   range ( 0 , z+1 )     if  a + b + c != n  ])

Given an array of integers, where all elements but one occur twice, find the unique element. Solution: n  =  int ( input ()) array  =  list ( map ( int ,   input () . rstrip () . split ())) for   element   in   array :      count  =  array . count ( element )      if   count  ==  1 :          print ( element )
