Answer:

Yes, The overall cost of wiring in addressable fire alarm system is significantly cheaper than the conventional one.But the addressale fire alram system is more reliable than a conventional system.

Explanation:

Conventional systems are hardware-based and use analog technology. where addressable fire alarm use digital technology. addressable system is generally more reliable than a conventional system mainly due to how the different systems are wired. With a conventional system, if a device’s wire is damaged or severed, its signal and the signal of other devices down the line cannot be transmitted to the control panel.

With an addressable system, both ends of the wire connect to the control panel. Therefore, if one end becomes damaged or severed, signals can still reach the control panel through the other end of the loop. In addressable systems, a device can be removed or disabled and it will not affect the other devices in the loop.

When using the BinarySearch() method of an array or list type, what value is returned when the element is not found? How can we

Step2247 [10]

Answer:

When the element is not found we return -1.

Explanation:

When we use binary search we use BinarySearch() method of an array or list type when the element is found we return the index of the element if found if the element is not found we return -1.

We can decode this value since it is less than 0 and the indexing of arrays and lists starts with 0 upto the size-1.So -1 index is not present in the array or list.We have to check if the index is < 0 then the element is not present in the array or list.

for ex:-

if(index<0)

{

System.out.println("Element is not present in the array");

}

The answer is B) Template.

Various templates are available in most all desktop publishing programs, from resume templates in Word to Income Statement templates in Excel. Templates are useful for skipping the general "setup" process of making a document, and allow you to focus more on filling the document with the relevant data and polishing it to your specific needs once most of the legwork is done.

Explanation:

[NB: since it is very long there is the need for me to put it it a document form. Kindly check the doc. Files. The file A is the sort Analysis.Java file and the file B is the sort.Java file].

The concept of algorithm time measurement strictly depends on the following;

=> The measurement of time, space or energy on different sizes.

=> Plotting of the measurements and characterizing them.

=> Running or implementation of the algorithm.

Programming language such as Java can be used in accessing the operating system clock and Java had two static methods.
