technology web technology

  1. myFunction()

  2. call myFunction()

  3. call function myFunction

  4. function myFunction

Show answer
Correct Option: A
Explanation:

To call a function named "myFunction", you need to use option A, which is "myFunction()". This syntax will execute the code inside the function and return any value that is specified in the function.

Option B, "call myFunction()", is incorrect because it is not valid syntax for calling a function in most programming languages, including JavaScript.

Option C, "call function myFunction", is also incorrect because it is not valid syntax for calling a function in most programming languages, including JavaScript.

Option D, "function myFunction", is incorrect because it only declares the function, but does not actually call it. To execute the code inside the function, you need to use the function name followed by parentheses, like in option A.

Therefore, the answer is: A. myFunction()

  1. Math.round(7.25)

  2. round(7.25)

  3. rnd(7.25)

  4. Math.rnd(7.25)

Show answer
Correct Option: A

AI Explanation

To round a number to the nearest whole number, you can use the Math.round() function.

Option A) Math.round(7.25) - This option is correct because the Math.round() function returns the value of a number rounded to the nearest integer. In this case, 7.25 will be rounded to 7, which is the nearest whole number.

Option B) round(7.25) - This option is incorrect because there is no standalone round() function in JavaScript. You need to use the Math.round() function.

Option C) rnd(7.25) - This option is incorrect because there is no rnd() function in JavaScript. You need to use the Math.round() function.

Option D) Math.rnd(7.25) - This option is incorrect because there is no Math.rnd() function in JavaScript. You need to use the Math.round() function.

The correct answer is Option A) Math.round(7.25) because it correctly rounds the number 7.25 to the nearest whole number.

Which of the following problems is not intented to be solved by WebServices?
technology web technology

  1. Interoperability

  2. User Interface

  3. Complexity

  4. Firewall traversal

Show answer
Correct Option: B
Explanation:

To solve this question, the user needs to understand the purpose of WebServices.

WebServices are designed to enable communication between different software applications, regardless of their programming languages, hardware, and operating systems. They are intended to solve interoperability problems, enabling different applications to exchange data and services seamlessly.

User interface, complexity, and firewall traversal are not the primary problems that WebServices are intended to solve. They are typically addressed by other technologies.

Option B, User Interface, is not intended to be solved by WebServices. User interface refers to the way users interact with software applications. WebServices are not designed to handle user interfaces; instead, they focus on the exchange of data between applications.

Option A, Interoperability, is the primary problem that WebServices are intended to solve. They enable applications to communicate with each other, regardless of their platforms, programming languages, and data formats.

Option C, Complexity, is not a problem that WebServices are specifically designed to solve. However, WebServices can help reduce complexity by providing a standardized way of exchanging data between applications.

Option D, Firewall Traversal, is not the primary problem that WebServices are intended to solve. However, they can help resolve this issue by using standard HTTP and XML protocols that can pass through firewalls more easily.

Therefore, the correct answer is:

The Answer is: B. User Interface
