A useful advantage of Asymmetric encryption over symmetric
encryption is that there is no secret channel necessary for the
exchange of the public key, unlike in the symmetric encryption which requires a
secret channel to send the secret key.
Another
advantage of Asymmetric encryption is that is has increased security. Asymmetric
uses two different keys (Public and private) for both encryption and decryption
of data while symmetric uses one.
Answer:
Quality Of Service
Explanation:
Technology that manages data traffic to reduce packet loss, latency and jitter on the network. QoS controls and manages network resources by setting priorities for specific types of data on the network.
Answer:

Explanation:
Given

Required
The result when
and
Analyzing the given instruction
a*=(++a)/(6)+(b++3)
Single out and solve the expressions in bracket
(++a) = a -- When the ++ operator appears before an operand, it is called pre increment. meaning that the operation will be done before the operand will be incremented.
So: in this case: ++a = a

The operator, as used in that statement is the same as: b + 3.
So:





The above expression is calculated as:

So:


Answer:
To sum up all the advantages of using the relational database over any other type of database, a relational database helps in maintaining the data integrity, data accuracy, reduces data redundancy to minimum or zero, data scalability, data flexibility and facilitates makes it easy to implement security methods.
