Answer:
O(N!), O(2N), O(N2), O(N), O(logN)
Explanation:
N! grows faster than any exponential functions, leave alone polynomials and logarithm. so O( N! ) would be slowest.
2^N would be bigger than N². Any exponential functions are slower than polynomial. So O( 2^N ) is next slowest.
Rest of them should be easier.
N² is slower than N and N is slower than logN as you can check in a graphing calculator.
NOTE: It is just nitpick but big-Oh is not necessary about speed / running time ( many programmers treat it like that anyway ) but rather how the time taken for an algorithm increase as the size of the input increases. Subtle difference.
Answer: The statement implies that the hackers psychologically manipulate the human to access the information they need.
Explanation: The author states that the hacker does not only exploits technology to get system access or to gather information. But there is another pivotal part of hacking. He refers to this part as "social engineering".
Social engineering from information security perspective means manipulate human emotions and convincing them to disclose some confidential information. Hacker often hacks or defrauds after gaining confidence and trust of a person.
Phishing is an example. It is a fraudulent technique for getting some secret information. Phisher sends an email pretending to be from some reputable organization to persuade people to divulge private information like passwords and credit card numbers, ATM card pin etc.
Answer:
A system programming language has low - level features that allow a software interface to write in an external device. Some computer uses computer languages such as PL/S, PL/I. This is an example of System Programming or Language programming.
Explanation:
The system language is a language used for system programming such as writing system software, which requires different development approaches when compared with application software.
System programming is the activity of the computer system. The characteristic of system programming when application programming produces software is that application that provides services to create software platforms.
A raid 1 and mirrored system writes data on two or more disks simultaneously, thereby creating a complete copy of all the information on multiple drives.
<h3>What is Disk mirroring?</h3>
In data storage, disk mirroring is a term that connote the doubling of logical disk volumes into a different physical hard disks so that it will always be available.
Conclusively, Note that this is mostly used in RAID 1. A mirrored volume is known to be full logical depiction of separate volume copies and as such the answer above is correct.

Answer:
batch sequence check.
Explanation:
A batch sequence check can be defined as a strategic and systematic control plan which typically involves the process of inputting a range of numbers comprising a batch and then inputting each serially numbered document.
The steps for checking an event data within a batch using a batch sequence check include the following;
I. You'll enter a range of serial numbers of the document in a batch.
II. You'll enter each serially pre-numbered document one after the other.
III. The input documents are sorted by a computer into a serial (numerical) order, match the sequence number range against the input documents, and then reports any part of the document that is missing, a duplicate and out of range.
