Outlook Express is an email client, which means it is a software program used to access and manage email messages. It allows users to send, receive, and organize emails from multiple email accounts. Unlike a browser or search engine, Outlook Express is specifically designed for email-related tasks and does not perform web browsing or internet search functions. Therefore, the correct answer is "E-Mail Client".

An FTP program is used to transfer files to and from an Internet server. This allows users to upload files from their local computer to a remote server, as well as download files from the server to their computer. It provides a convenient and efficient way to manage and transfer files over the internet. Designing a website and connecting to the internet are not specific functions of an FTP program.

The input tag in HTML is used to create an input field where users can enter text. It allows users to input various types of data such as text, numbers, dates, etc. By using the input tag, developers can easily take input text from users on an HTML page.

The .com domain represents the commercial domain. This is because the .com extension is primarily used by businesses and commercial organizations to establish their online presence. It is the most common and widely recognized top-level domain for commercial websites.

The correct HTML for inserting an image is "". This is because the "img" tag is used to insert an image in HTML, and the "src" attribute specifies the source or URL of the image file. The "alt" attribute is used to provide alternative text for the image, which is displayed if the image cannot be loaded or for accessibility purposes.

The correct answer is mysql_connect() function. This function is used in PHP to establish a connection with a MySQL database. It takes parameters such as the server name, username, password, and database name, and returns a connection object that can be used to execute SQL queries and perform database operations.

Servlets are used to program the server component in a web application. They are Java classes that run on a web server and handle requests and responses from clients. Servlets are responsible for processing user input, interacting with databases, and generating dynamic web content. They are an essential part of server-side programming in web development.

When an email is sent, the message is divided into smaller units called packets. These packets contain a portion of the message along with the necessary information to route them through the network. This division into packets allows for efficient transmission of data over the internet, as each packet can take a different route and be reassembled at the destination. Therefore, the correct answer is "Packets".

The given postfix expression can be evaluated as follows:
- Start by evaluating the sum of 10 and 5, which is 15.
- Then, evaluate the division of 60 by 6, which is 10.
- Next, multiply the previous result (10) by 10, resulting in 100.
- Finally, subtract 8 from the previous result (100), resulting in 92.
Therefore, the correct answer is 92. However, the given answer of 142 is incorrect.

The correct way to write a JavaScript array is by using the syntax: var salaries = new Array(39438, 39839,83729). This syntax creates a new array object called "salaries" with three elements: 39438, 39839, and 83729.

The given IP address, 192.168.56.115, is a valid IP address because it follows the standard format of four sets of numbers separated by periods. Each set of numbers should range from 0 to 255, which is the valid range for an IP address.

MIME stands for Multipurpose Internet Mail Extension. This is a protocol that allows email clients to exchange different types of data, such as text, images, audio, and video. It enhances the capabilities of the basic Internet email system by enabling the transmission of multimedia content. The correct answer is "Multipurpose Internet Mail Extension".

The similarity between a structure, union, and enumeration is that all of them allow you to define new data types. Structures allow you to group related variables together, unions allow you to store different types of data in the same memory space, and enumerations allow you to define a set of named values. These data types can then be used to create variables and manipulate data in a more organized and meaningful way.

The given statement sets the (n+1)th bit of x to 1. It uses the bitwise OR operator (|) and the left shift operator (

To get the number of records or rows in a table, we can use the COUNT function. This function allows us to count the number of rows in a specified table. By using the COUNT function, we can easily retrieve the total number of records present in the table.

The correct answer is "vh", which stands for viewport height. Viewport height refers to a percentage of the height of the browser window. So when we say 1% of viewport height, it means that it is 1% of the total height of the browser window.

The vlink attribute refers to a visited link. This attribute is used in HTML to specify the color of a link that has been visited by the user. When a user clicks on a link and visits the corresponding web page, the vlink attribute allows the web developer to define a specific color for that visited link. This helps the user to easily identify which links they have already visited on a website.

To implement a queue using stacks, we need two stacks. The first stack is used to enqueue elements, where we push elements into it. The second stack is used to dequeue elements, where we pop elements from it. By using two stacks, we can simulate the FIFO (First-In-First-Out) behavior of a queue. When we need to enqueue an element, we push it into the first stack. When we need to dequeue an element, we check if the second stack is empty. If it is empty, we transfer all the elements from the first stack to the second stack in reverse order. Then we pop the top element from the second stack, which gives us the element that was first enqueued.

Michael Widenius is considered the "father" of MySQL because he was one of the original developers of the open-source database management system. Along with his partner David Axmark, Widenius created MySQL in the 1990s while working for a Swedish company called TcX. He played a crucial role in designing and developing the early versions of MySQL, which eventually became one of the most popular and widely used database systems in the world. Widenius's contributions to the development and success of MySQL make him the correct answer to this question.

The binary number 1011011111000101 can be easily converted to the hexadecimal system because hexadecimal is a base-16 numbering system, which means it uses 16 digits (0-9 and A-F) to represent numbers. Since binary is a base-2 system (only 0 and 1), converting it to hexadecimal simplifies the representation by grouping the binary digits into sets of four and replacing each set with its corresponding hexadecimal digit.

During preprocessing, the code undergoes several transformations before it is compiled. One of these transformations is the replacement of the "gets" function with the contents of the file "stdio.h". This is done by the preprocessor, which is a part of the compilation process that handles directives starting with a hash symbol (#). It scans the code for these directives and performs actions based on them, such as including header files like "stdio.h". Therefore, the correct answer is "During preprocessing".

HTML (Hypertext Markup Language) was first proposed in the year 1990. This means that the concept and initial specifications for HTML were introduced and put forward for consideration in that year. It is important to note that while HTML has evolved and undergone various revisions since its initial proposal, 1990 marks the beginning of its development and the foundation of the language that is widely used for creating web pages today.

HSL stands for Hue Saturation Lightness. Hue refers to the color itself, Saturation refers to the intensity or purity of the color, and Lightness refers to the brightness or darkness of the color. This color model is often used in computer graphics and image editing software to represent and manipulate colors.

A valid XML document means that it adheres to the rules and structure defined in its associated DTD (Document Type Definition). The DTD specifies the elements, attributes, and structure that the XML document must follow. Therefore, for a document to be considered valid, it must have a DTD associated with it and comply with the rules defined in that DTD. The other options mentioned in the question, such as having a root element or nesting elements properly, are important aspects of XML documents but do not define its validity.

The correct answer is the Manifest file. The Manifest file in Android Studio holds the permission to use the internet. This file is responsible for declaring the components of an application, such as activities, services, and permissions. By including the appropriate permission in the Manifest file, an application can access the internet and make network requests.

HTML uses fixed tags defined by the language. These tags are predefined and have specific meanings and functions within the HTML language. They are used to structure and format the content of a webpage, such as headings, paragraphs, lists, images, and links. Each tag has a specific syntax and is enclosed in angle brackets. By using these fixed tags, developers can create well-organized and standardized webpages that can be interpreted correctly by web browsers.

When referencing an HTML element preceded by a # (pound or hash), the equivalent JavaScript function is getElementById. This function is used to select an element in the HTML document by its unique ID attribute. It returns the first element that matches the specified ID. The other options, getElementByClassName and getElementByTagName, are not applicable in this case as they are used to select elements based on class names and tag names respectively.

The program declares two constants, EVEN and ODD, with values 0 and 1 respectively. It then initializes the variable i with a value of 3. The switch statement checks the result of the bitwise AND operation between i and 1. Since 3 AND 1 is equal to 1, the case ODD is selected. Therefore, the output of the program will be "Odd".

The correct answer is 4. The PRINT macro is defined with a do-while loop that continues indefinitely (while(1)). Inside the loop, there is a condition (i++

The given C declaration defines 's' to be an array, where each element is a pointer to a structure of type node. This means that 's' is an array that can hold multiple pointers, and each pointer points to a structure of type node.

The given code is trying to declare a function pointer named 'ptr' and initialize it with the function 'fun'. However, the function 'fun' is defined after the declaration of the function pointer, which results in a compile-time error. This is because the compiler needs to know the prototype of the function before it is used. Therefore, the code will not compile successfully.

The given code is assigning a value of 25 to the "bolts" variable within the "engine" structure, which implies that the "bolts" variable is nested within the "engine" structure. Since the code is accessing the "bolts" variable through the "maruti" structure (maruti.engine.bolts), it can be inferred that the "engine" structure is nested within the "maruti" structure. Therefore, the correct statement is "Structure engine is nested within structure maruti."

In this program, the variables a and b are initialized to 1.

In the line "int c = a || --b;", the logical OR operator (||) is used. Since the left operand (a) is true (non-zero), the right operand (--b) is not evaluated. Therefore, the value of c is 1.

In the line "int d = a-- && --b;", the logical AND operator (&&) is used. Both the left operand (a--) and the right operand (--b) are evaluated. The value of a-- is 1, but since it is a post-decrement operator, the value of a is then decremented to 0. The value of --b is 0, as b is decremented before the evaluation. Therefore, the value of d is 0.

Finally, the printf statement prints the values of a, b, c, and d, which are 0, 0, 1, and 0 respectively.

The correct answer is . This is because the tag is specifically used to create a drop-down box in HTML. The tag does not exist in HTML, and the is not a valid input type for creating a drop-down box. Therefore, the correct choice is .

The output of the program is "8 4". The size of the object 't' of class Test is 8 bytes because it contains an integer 'x' (4 bytes), a pointer 'ptr' (4 bytes), and an integer 'y' (4 bytes). The size of a pointer to the Test class is 4 bytes because a pointer always takes the same amount of memory regardless of the type it is pointing to.

The given recursive function takes two parameters, x and y. If x is equal to 0, the function returns the value of y. Otherwise, it recursively calls itself with the parameters x-1 and x+y.

In the case of fun(4, 3), the function will not return y immediately because x is not equal to 0. It will instead call itself with the parameters 3 and 7 (4-1 and 4+3).

Again, the function will not return y immediately because x is still not equal to 0. It will call itself with the parameters 2 and 10 (3-1 and 3+7).

This process continues until x becomes 0. When x becomes 0, the function will return the value of y, which is 13. Therefore, the value of fun(4, 3) is 13.

The use of "extern" before a function declaration means that the function is made globally available. It allows the function to be accessed and used by other files or modules in the program. In this case, the function "sum" can be called and used in any part of the program where it is needed. The "extern" keyword ensures that the function is visible and accessible outside of its own file.

The correct jQuery code to set the background color of all p elements to red is $("p").css("background-color","red"). This code selects all p elements using the $("p") selector and then uses the css() method to set the background-color property to red.

The operation of deleting the last element of the list is dependent on the length of the linked list. If the linked list has only one element, deleting the last element would result in an empty list. However, if the linked list has more than one element, deleting the last element would require traversing the entire list to reach the second-to-last element and update its next pointer. Therefore, the length of the linked list affects the complexity and feasibility of deleting the last element.

Vaadin, AngularJS, and KendoUI are all well-known JavaScript frameworks for UI development. However, Springcore is not a JavaScript framework for UI. Springcore is a Java-based framework used for building enterprise-level applications. It provides dependency injection and inversion of control features for Java applications, but it is not specifically designed for UI development in JavaScript.

Merge Sort can be used to sort a random linked list with minimum time complexity because it has a time complexity of O(n log n) in the average and worst case scenarios. This is because Merge Sort divides the linked list into two halves, recursively sorts each half, and then merges the sorted halves back together. This approach ensures that the time complexity remains efficient even for large linked lists. In contrast, Insertion Sort has a time complexity of O(n^2) in the worst case, Quick Sort has a time complexity of O(n^2) in the worst case, and Heap Sort has a time complexity of O(n log n) in the best, average, and worst case scenarios.

The correct answer is 4095 bytes. Cookies are small text files that are stored on a user's computer by a website. They are commonly used to store information such as user preferences or login credentials. The storage capacity of a single cookie is limited, and in this case, it is limited to 4095 bytes. This means that the information stored in a single cookie cannot exceed this size.

The given code fragment prints "GATE2018".


- The variable "c" is an array of characters initialized with the string "GATE2018".
- The variable "p" is a pointer to the first character of the array "c".
- In the printf statement, "p[3]" refers to the character at index 3 of the array "c", which is 'E'.
- Similarly, "p[1]" refers to the character at index 1 of the array "c", which is 'A'.
- The expression "p + p[3] - p[1]" evaluates to "p + 'E' - 'A'", which means it moves the pointer "p" by 3 positions.
- Therefore, when we print "%s" with the modified pointer "p", it prints the string "GATE2018".

The function prototype with an empty parameter list in C means that the function can be called with any number of parameters of any types. This means that the function does not have any specific parameter requirements and can accept any arguments passed to it.

Type conversion from float to char pointer is not accepted because it involves converting a floating-point value to a pointer type, which is not allowed in most programming languages.

The regional networks are connected to the corporate networks through a backbone, which refers to a central infrastructure that interconnects different networks. This backbone enables efficient communication and data transfer between the regional and corporate networks. It acts as a high-speed pathway for transmitting data and supporting the overall network infrastructure.

The protocol "WIRL" is not used in the Internet. Telnet, HTTP, and Gopher are all protocols that are used in the Internet. Telnet is a network protocol used for remote terminal connections, HTTP is the protocol used for transferring hypertext over the Internet, and Gopher is a protocol used for distributing, searching, and retrieving documents. However, "WIRL" is not a recognized protocol used in the Internet.

The program is trying to multiply the variable y by NULL, which is a null pointer constant. In C, when a null pointer constant is used in an arithmetic operation, it is treated as the integer constant 0. Therefore, the result of the multiplication will be 0. The program then prints the value of x, which is 0.

JDBC template is a commonly used method to connect to a database in a web application. JDBC (Java Database Connectivity) is a Java API that allows Java programs to access and interact with databases. The JDBC template provides a higher level of abstraction and simplifies the process of database connectivity by handling low-level details such as opening and closing database connections, executing SQL queries, and processing query results. It provides a convenient and efficient way to connect to various databases, including Oracle, MySQL, and others.

Web fonts in HTML enable the use of fonts over the web without requiring users to install them. This means that web designers can choose from a wide variety of fonts to enhance the visual appeal of their web pages, without worrying about whether or not the user has that specific font installed on their device. This allows for greater creativity and flexibility in web design, as designers are not limited to a small set of default fonts.
