Answer:
C. attributes
Explanation:
A relational database is a database system that stores information within its servers. It has rows and columns that contain the data stored in them and which can be accessed at any time with the right administrative privileges.
In a relational database, entities are defined by their attributes. This is because an entity is the data that needs to be stored so, the attribute specifies that information and gives its value.
Answer:
The height of tallest possible red-black tree having 31 values is 10.
Explanation:
The height of tallest possible red-black tree = 2㏒₂(n+1)
here we have n=31 So substituting the value of n in the equation.
=2㏒₂(31+1)
=2㏒₂(32)
=2㏒₂(2⁵) since ㏒(aⁿ)=n㏒(a)
=2x5㏒₂(2)
=10㏒₂(2) since ㏒ₙ(n)=1.
=10.
Answer: Two direction
Explanation: Doubly linked list is a data structure which contains node's end linked with the start of the next node and also a previous pointer .These node persist two link fields and one data field in the doubly linked list.
The transversing as well as searching can be done in both direction. Inorder transversal (forward direction)and the reverse order (backward direction)transversal are the techniques through which the reversal is carried out in two ways.
Answer:
A worm
Explanation:
A worm, like a virus, is a type of malware that moves from computer to computer (most commonly through networks) and can cause malicious problems. Unlike virus, a worm can stand alone - it is a complete program on itself. It basically does not need to depend on other files before it unleashes its potentials. In other words, it could operate more or less independently of other files. Also, unlike virus, a worm may not cause a terrible harm to a network. It could just be something less serious as just consuming bandwidth.
