Set Theory and algebra
If we are given a set for ex.S={1,2,.....25} and now if we want to find subsets T ⊆ S of size 5 than it is 25C5 or they are 2^ 25C5.

Internal organization of memory chip.
What are external connection in "internal organization of memory chip" ? How these lines are decided ? Example memory with 128 bits (16×8) requires 14 external connections. How we decided this ☝ ?

difference between if(a=0) and if(a=non zero)
what is the differernce between if (a=0) and if (a= -7) or any other non-zero number e.g what will be the out put of following program a)if ( a=0) printf(""a is zero ") else printf("a is not zero") and if we replace 0 by some +ve or -ve number then

Threads
Since every thread can access every memory address within the process’ address space, one thread can read, write, or even wipe out another thread’s stack. I am not getting the above statement, stack is specific to a thread then how we can access other thread's stack through Process' address space?
