How is the numeric string that makes up a digital signature created?

1 answer:

7 0

A numeric string is created by a cryptographic algorithm, which is called a hash that is used to validity of a message or authenticity of a document. The signature is verified by an algorithm that uses the stated owner of the signature's public key to accept or reject the authenticity of a signature. A certification authority's digital signature is used to verify the authenticity of digital certificates and other documents in a PKI.

Non-preemptive Shortest Job First (SJF) scheduling policy is not optimal if:

ivann1987 [24]

Answer:

The answer is A

Explanation:

Basically, Shortest job first (SJF) is a scheduling policy that selects jobs on queue for execution within a short execution time.

From the definition of SJF above, it means that there are a lot of process on queue and the (SJF) job is to receive processes on queue to execute within a short execution time.

Therefore, if all the jobs or process arrives at the SJF at the same time, the SJF will forfeit one of its major purpose which is scheduling of jobs.

That will therefore not make Non-preemptive Shortest Job First (SJF) not function at its optimal point.
