Answer:
2
Explanation:
The second option is the only one that will work. The last would work but doesn't make the code any shorter.
Answer: Keyboard hardware & the operating system
Explanation:Keystroke loggers is also referred as the monitoring system which is a for the inspection of the every key pressed on an operating system. This technology monitors the activities of keypad devices such as smart phones etc. It is also used for the surveillance of the unauthorized activities that are done by the hackers or criminals.
Thus the correct option is keyboard hardware and the operating system is the location of the placement of the key loggers.
Answer:
Follows are the matching to this question:
Explanation:
Column A Column B
1 c
2 d
3 b
4 a
Description of the matching:
- In 1(Acid) the correct choice is (c) because the acid (HCl) dissociates to both the H+ ion and the Cl- ion as a solution.
- In 2(Alkaline ) the correct choice is (d) because alkaline NaOH is a solution that differentiates between the ions ( OH-) and Na+.
- In 3(pH ) the correct choice is (b) because for an A compound of less than 7 is an acid and an alkaline pH compound of more than 7. For neutral compounds, a pH of 7 is applicable.
- In 4(Ion) the correct choice is (a) because Na+ ion is loaded positive, and Cl-ion is loaded negatively.
The object-oriented analysis method of developing systems produces code that is modular and reusable.
<h3>What is object oriented system analysis?</h3>
Object-oriented systems analysis and specification (OSA) is known to be a kind of a method that is often used in regards to systems analysis and this is known to be one that helps to create or builds on the strengths of former systems and, at also at the same time, look into their weaknesses.
Note that this is said to be the basic idea behind the OSA methodology that are known to be described. The framework of OSA system models is known to be object class.
Hence, The object-oriented analysis method of developing systems produces code that is modular and reusable.
