Explanation:
Concurrency Control in Database Management System is a procedure of managing simultaneous operations without conflicting with each other. It ensures that Database transactions are performed concurrently and accurately to produce correct results without violating data integrity of the respective Database.And The ACID properties, in totality, provide a mechanism to ensure correctness and consistency of a database in a way such that each transaction is a group of operations that acts a single unit, produces consistent results, acts in isolation from other operations and updates that it makes are durably stored.

Explanation:
The IEEE has given some Standards for representing numbers
IEEE Standards for floating point numbers is common convention for representing numbers in binary on Computers.
Double precision number format takes up 64 bits.
Single precision number format takes up 32 bits
Answer:
Answer is B, see explanations.
Explanation:
Answer is (B) NP−complete∩P=ϕ
Since, P≠NP, there is at least one problem in NP, which is harder than all P problems. Lets take the hardest such problem, say X. Since, P≠NP,X∉P .
Now, by definition, NP−complete problems are the hardest problems in NP and so X problem is in NP−complete. And being in NP, X can be reduced to all problems in NP−complete, making any other NP−complete problem as hard as X. So, since X∉P, none of the other NP−complete problems also cannot be in P.
