5.How do you call a function named "myFunction"?

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()

9.How do you round the number 7.25, to the nearest whole number?

technology web technology

  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.

10.How do you find the largest number of 2 and 4?

technology web technology

  1. Math.ceil(2,4)

  2. Math.max(2,4)

  3. top(2,4)

  4. ceil(2,4)

Show answer
Correct Option: D

AI Explanation

To find the largest number between 2 and 4, you can use the Math.max() function in JavaScript.

Let's go through each option to understand why it is correct or incorrect:

Option A) Math.ceil(2,4) - This option is incorrect because the Math.ceil() function is used to round a number up to the nearest whole number. It is not used to find the largest number among a set of numbers.

Option B) Math.max(2,4) - This option is correct. The Math.max() function returns the largest of the given numbers. In this case, it will return 4, which is the largest number between 2 and 4.

Option C) top(2,4) - This option is incorrect because there is no built-in JavaScript function called "top()". Therefore, it cannot be used to find the largest number.

Option D) ceil(2,4) - This option is incorrect because the ceil() function is used to round a number up to the nearest whole number. It is not used to find the largest number among a set of numbers.

The correct answer is B) Math.max(2,4). This option is correct because it correctly uses the Math.max() function to find the largest number between 2 and 4.

3.How do you write "Hello World" in an alert box?

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

  5. None of these

Show answer
Correct Option: D

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) It is a communication protocol - This option is correct. SOAP (Simple Object Access Protocol) is a communication protocol used for exchanging structured information in web services.

Option B) It is a format for sending messages - This option is correct. SOAP defines a format for sending messages over a network, typically using HTTP or other protocols.

Option C) It is based on XML - This option is correct. SOAP messages are typically formatted using XML (eXtensible Markup Language).

Option D) It does not allow you to get around firewalls - This option is incorrect. SOAP can be used to get around firewalls because it is typically transmitted over HTTP or other protocols that are allowed through firewalls.

Option E) None of these - This option is incorrect. As discussed, all of the previous options are applicable to SOAP.

The correct answer is D) It does not allow you to get around firewalls. This option is incorrect because SOAP can be used to get around firewalls by transmitting messages over HTTP or other protocols that are allowed through firewalls.

This method ensures that each XML element type and attribute name has a unique identity

technology web technology

  1. named pipe

  2. fully-qualified domain name

  3. Multiprotocol Label Switching

  4. namespace

Show answer
Correct Option: D
Explanation:

To solve this question, the user needs to understand the concept of XML elements and attributes, as well as the purpose of ensuring unique identities for these elements and attributes.

Explanation of each option:

A. named pipe: A named pipe is a method of inter-process communication in which two or more processes can communicate with each other by writing and reading from a pipe. This option is unrelated to the concept of unique identities for XML elements and attributes.

B. fully-qualified domain name: A fully-qualified domain name (FQDN) is a domain name that specifies the exact location of a resource on the internet. This option is unrelated to the concept of unique identities for XML elements and attributes.

C. Multiprotocol Label Switching: Multiprotocol Label Switching (MPLS) is a routing technique that directs data packets along predefined paths within a network. This option is unrelated to the concept of unique identities for XML elements and attributes.

D. namespace: A namespace in XML is a mechanism that allows elements and attributes to have unique identities. It ensures that element and attribute names are globally unique, preventing naming conflicts. This is the correct option for ensuring unique identities of XML elements and attributes.

Therefore, the correct answer is:

D. namespace
