Answer: C) spin-lock with test and set
Explanation:
In spinlock, when a thread locks a spinlock then it continuously retrying locking until it succeeds. Spinlock is the lock that cause thread and continuously check that whether the lock are available or not for synchronization.
So that is why spinlock is best synchronization solution as it is not allowing any another thread.
On the other hand, in mutex thread try to lock a mutex and then, it automatically go to sleep mode before locking and immediate allow another thread to run.
Answer:
D. Network vulnerability database
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
In this scenario, The director of security at an organization has begun reviewing vulnerability scanner results and notices a wide range of vulnerabilities scattered across the company. Most systems appear to have OS patches applied on a consistent basis but there is a large variety of best practices that do not appear to be in place. Thus, to ensure all systems are adhering to common security standards a Network vulnerability database, which typically comprises of security-related software errors, names of software, misconfigurations, impact metrics, and security checklist references should be used.
Basically, the Network vulnerability database collects, maintain and share information about various security-related vulnerabilities on computer systems and software programs.
Answer:
false
Explanation:
The term 'computationally expensive' means that a given mathematical function, code or an algorithm has high computational complexity. In addition, the mathematical function or algorithm will require several steps and procedures to be completed. Based on this, the statement made in this question is not true.
You can list the numbers . keep listing them till you find the same numbers
Answer:
REM PROGRAM TO CONVERT TEMPERATURE IN CELCIUS TO FARENHEIT
CLS
INPUT “ENTER TEMPERATURE IN CELCIUS”; C
F = C * (9 / 5) + 32
PRINT “TEMPERATURE IN FARENHEIT=”; F
END
