3.E.eid , E.sal, E.hobby ,E.did , D.did, D.floor ,D.dname , D.budget.

4.E.eid , D.dname

The attributes that are examined for the query are the attributes of the table that are mentioned in the select statement and where clause.

So according to first query we are working on all attribues of Emp table so all of the attributes of Emp table are examined.In second query we selecting all attributes of both the tables hence all attributes of both the table and same in the next query.

In fourth query though the query is not complete where clause is missing but we have eid from Emp and dname from Dept tables for sure and the attributes mentioned in where clause will also be present.

which type of cryptography provides the most security?

Doss [256]

Answer B: Asymmetric cryptography, because the receiver has its own decryption key and cannot create encrypted messages, because he doesn't have the encryption key.

About the other answers:

A: Private keys are always involved, there has to be some secret to do encryption, so this answer doesn't say very much.

C: Digital signatures can be used to verify/prove some data comes from some person (the signer) in an unaltered way. It is not about encryption, so is not about the security of your message. You use it in combination with encryption.

D: Like A, this doesn't say very much. Shared secret keys (symmetric keys) can be used for encryption, but they are less secure since the keys have to exist in more than one place (sender and receiver).

Contrast and compare: an array, a stack, and a queue. Identify the principal uses of each and give an example.

Soloha48 [4]

Answer:

All three of them are linear Data Structures.

A stack is a FILO(First In Last Out) or LIFO(Last In First Out) type data structure means first inserted element will be the last one to be removed form the stack.Insertion and Deletion is from one end only called head.

ex:-A stack of books on the shelf.

A queue is FIFO(First In First Out) type means the first inserted element will be the first one to be removed.In queue insertion is from the back or tail and removal of elements is done form the front.

ex:-A queue at the ticket counter.

In array each element stored is given an index, by which we can be access the element very easily. We can use this index to modify or store element at that index of the array. i.e any object can be accessed with the right index, unlike queue and stack.

We can access only the front and back in the queue.In stack we can access only the top but in array we can access any element with the index.
