After the statements that follow are executed,var firstName = "Ray", lastName = "Harris";
var fullName = lastName;
fullName += ", ";
fullName += firstName;

a.firstName="Harris"
b.firstName="Ray Harris"
c.fullName="Ray Harris"
d.fullName="Harris, Ray"

Answers

Answer 1
Answer:

Answer:

d. fullName="Harris, Ray"

Explanation:

// here we define two variables firstName="Ray" and lastName= "Harris"

var firstName = "Ray", lastName = "Harris";

// then we create another variable fullName and assign it the value stored in variabl lastName that is "Harris"

var fullName = lastName;

// then we added a coma and space. At this point fullName= Harris,

fullName += ", ";

// then we added firstName to the variable fullName. At this point fullName=Harris, Roy

fullName += firstName;

Note: the += operator means that add the variable on the left by an amount on the right

a+= b; or a = a + b; both mean same

In almost all cases, touching power lines or coming into contact with energized sources will result in what? Select the best option. First degree burns
Severe injuries or death
Neurological damage
Amputations

Answers

In almost all cases, touching power lines or coming into contact with energized sources will result in Severe injuries or death. Thus, option second is correct.

What is energized sources?

Electrical, mechanical, chemical, pneumatic, chemical, thermal, and other energy sources in machinery and equipment can be harmful to employees.

De-energization may entail turning off a machine and unplugging it, or removing a switch before applying a lock to prevent the equipment from being accidentally starting up. Lockout can be enforced once energization is complete.

Touching electricity lines or making contact with electrical sources will almost always result in severe injury or death. As a result, option two is correct.

Debugging is not testing, but always occurs as a consequence of testing. A) TRUE
B) FALSE

Answers

It is true to say that Debugging is not testing but always occurs as a consequence of testing.

What is Debugging?

Debugging is the process of identifying and fixing defects in computer programs, software, or systems. It is a crucial step in computer programming and software development.

Debugging is used to identify and correct errors. The testing procedure just displays the consequences of the coding fault on the application; it does not assist the developer in identifying the mistake in the code.

Software developers and engineers use debugging to find and correct bugs in programs before making them available to the general public. It's an additional step to testing, which entails discovering how an issue impacts a program as a whole.

Debugging is the act of locating and fixing problems in software code that might lead to unexpected behavior or crashes. These mistakes are sometimes referred to as "bugs." Debugging is used to identify and fix faults or flaws in software or systems so that they don't operate incorrectly.

Give a non-network example of hierarchical addressing and discuss how it reduces the amount of work needed in physical delivery. Do not use the postal service, or the telephone network..

Answers

HIERARCHICAL EXAMPLE.

Many examples of hierarchical addressing exists which reduces the amount of work needed in locating or in delivering,and one of such examples is the 'sorting of books in a library'.

Looking at a library having books kept randomly on any stack and shelf,it will make it difficult finding any book easily or locating any book of a specific genre.so,to avoid such problems, books are orderly sorted in a library and each book is given or has a unique identification number.

Books that has the same or related subject are kept in the same stack and books of the same genre are also kept together.

In a library,there are many stacks having different rows.

Take for an example; If one need to find a book on computer network,the user can search for the books in stacks of books that are related to Computer Science instead of searching the whole library for the book.

So,the hierarchical addressing saves lots of work and also time required for searching a specific book in the library.

If you have a list consisting of just numbers, then you can add all of the values in the list using the sum() function. If your list consists of some numbers and some values of other types (e.g., lists, strings, sets), the sum() function will fail. In this question, we're asking you to write a function that will sum all of the numbers in a list, ignoring the non-numbers. The function below takes one parameter: a list of values (value_list) of various types.


The recommended approach for this:

(1) create a variable to hold the current sum and initialize it to zero,

(2) use a for loop to process each element of the list,

(3) test each element to see if it is an integer or a float, and, if so, add its value to the current sum,

(4) return the sum at the end.

Raj, a recent graduate, has recently joined your organization as a Junior Business Analyst. He has been asked to conduct a Feasibility Analysis on whether to automate the process of software installation or not. If you were in Raj's place, based on which of these parameters would you identify if that process can be automated? Pick onea. Availability of software licensingb. Entering license number during installationc. Operating System being usedd. Software version being used

Answers

Answer:

a. Availability of software licensing

Explanation:

With feasibility analysis, we take into consideration economic, technical, legal, and scheduling factors to make sure that our project completes successfully. Acquiring license for a software can be free of cost or paid subscription. So a business analyst needs to make an account of the cost of accessing the software services. Also while automating a software installation process, it would require automatic authentication which would again require details of licensing. So in my best knowledge, analyzing availability of software licensing is a must and foremost step for a feasibility study.
