Software Fundamentals Hardest Quiz! Trivia

The activities of an application lifecycle are likely to take place in the following order: requirements analysis, design, coding, testing, and release.

Cascading Style Sheets (CSS) help you define the formatting and layout of a page’s content and store that separately from the content.

HTML is a text-based language that uses various markup tags that describe how content is displayed.

JavaScript is scripting language that you use to add functionality and behavior to a Web page.

HTTP is the underlying communication protocol used by the World Wide Web.

The BubbleSort algorithm uses a series of comparison and swap operations to arrange list elements in the correct order.

The HTML IMG tag is used to display the images on a Web page. The source of the image can be on the same or a different Web server.

The LINK tag is used to link a CSS file with the HTML page.

The A tag is used to create anchor links.

The HTML tag is used to specify the contents of a Web page.

An architect designs the technical blueprint of the system. This includes identifying components and services, their behavior, and how they interact with each other and with the external world.

A stack is a collection of items in which the last item added to the collection is the first one to be removed.

Identify a technical writer for this task. Technical writers develop the system manuals and help files that will be delivered with the application.

Black-box testing treats the software as a “black box,” focusing solely on inputs and outputs. On the other hand, white-box testing is used to make sure that each method or function has proper test cases available. Alpha and beta testing are both black-box types of testing.

The peek operation allows you to look at the current item at the top of the stack without actually removing it. The contains operation allows you to determine whether a particular item exists in the stack. The push operation adds an item to the top of the stack. The pop operation removes the element at the top of the stack.

Release management includes activities such as packaging and deploying the software, managing software defects, and managing software change requests. The release manager coordinates various teams and business units to ensure the timely release of a software product.

After the first statement, the content of the stack is (50). After the second statement, the stack contents from top to bottom are (45, 50). After the third statement, the top element is popped, resulting to (50). After the fourth statement, another element is added to the top, resulting to (11, 50). After the fifth statement, the top element is popped, resulting to (50). Finally, the sixth statement is executed and the result of stack is (7, 50).

Each node in a linked list contains of two pieces of information: the data corresponding to the node, and the link to the next node.

The first node of the list is called the head node. Using this link, you can get to the next node and continue traversing nodes until the final link is a null value.

The design activity is used to create plans, models, and architecture for how the software will be implemented.

Use the testing activity to assure the quality of the final product. Testing can identify possible gaps between the system expectations described in the requirements document and actual system behavior.

Use cookies because they allow you to store a small amount of information on the user’s computer. Hidden fields, view state, and sessions are not correct because these options cannot store information across browser restarts.

JavaScript is a client-side scripting language that runs inside Web browsers to help create far more interactive Web pages than are possible with only HTML.

C# code does not run within Web browsers.

Writing code that runs on a Web server increases transmission of information across networks and provides slow response to the users.

To create a hyperlink to another Web page, use the HREF attribute of the tag.

The IMG tag is used to specify the location of an image.

The LINK tag is used to link to a CSS resource.

The HTML tag is used to specify the contents of a Web page.

After you partition the array, you need only to sort the left and right sides of the array. The middle element is automatically sorted.

To sort the left array, use the expression QuickSort( numbers, left, pivotIndex - 1); to sort the right array, you should use the expression QuickSort(numbers, left, pivotIndex + 1).

In a queue, items are processed in the order in which they were added to the queue. In particular, items are always added at the end of the queue and removed from the front of the queue. This is also commonly known as first-in, first-out (FIFO) processing.

Use noscript element to display a specific message to users when their browser is not running JavaScript.

The script tag is ignored when JavaScript is not enabled.

The % ... % and script runat="server" … /script tags are used only for server-side programming.

Alpha testing—performed by a limited group of users—provides opportunities to give the most important customers an early look at the product and to gather feedback. Alpha releases may miss some features and generally lack many nonfunctional attributes such as performance. In the next level of testing, beta testing, you release the product to a wider audience of customers and solicit feedback. In terms of functionality, the beta release of the software is very close to the final release. However, the development teams might still be working on improving performance and fixing known defects.

The method that handles the Load event is the most appropriate place for writing initialization code such as this.

You should not be including the Visual Studio InitializeComponent method in your code. The method that handles the Init event does not have access to the controls because they are available only after the page is initialized.

If you write the code in the method that handles the PreRender event, any changes to the control’s properties do not have a visible effect because the page is already ready to be rendered.

When the AutoEventWireup attribute of the @Page directive is set to true, specially named methods such as Page_Load are automatically wired up with their corresponding events. When the AutoEventWireup attribute of the @Page directive is set to false, the Page_Load method is not associated with the Load event of the Page class. The IsCallBack property of the Page class indicates whether the page request is the result of a callback.

The IsPostBack property of the Page class indicates whether the page request is the result of a post-back operation.

A linked list is a collection of nodes in which each node contains a reference (or link) to the next node in the sequence.

Unlike in an array, items in a linked list need not be contiguous; therefore, a linked list does not require reallocation of memory space for the entire list when more items must be added.

As the defects in a software application are reported and fixed, you need to make sure that each new fix doesn’t break anything that was previously working. This is where regression testing comes in handy. With every new fix, software testers usually run a battery of regression tests to make sure that every function that was already known to work correctly is still working.

The contains operation allows you to determine whether a particular item exists in the queue.

The peek operation allows you to look at the current item at the head position without actually removing it from the queue.

The enqueue operation adds an item to the tail end of the queue.

The dequeue operation removes the current element at the head of the queue.

The aspnet_wp.exe (ASP.NET Worker Process) file handles the Web requests for ASP.NET resources. The ASP.NET ISAPI extension (aspnet_isapi.dll) is responsible for invoking the ASP.NET worker process (aspnet_wp.exe), which, in turn, controls the execution of the request.

The inetinfo.exe is the Internet Information Services process.

The iexplore.exe process is for the Internet Explorer Web browser.

In the .NET Framework, all arrays are zero-based. A two-dimensional array can be thought of as a table in which each cell is an array element and can be addressed using the numbers of the row and column to which it belongs. Both the row number and column number are indexed by zero. For example, the expression number[2, 3] would refer to an item in the third row and fourth column of an array, which in this case is 34.

Because you need to perform frequent insert and delete operations, using a linked list is better than using arrays.

Also, because you need access to both previous and next records, you must use a doubly linked list.

The linked list and circular linked list let you traverse in only one direction.

You should write JavaScript code in a separate file and then use the SRC attribute of the SCRIPT tag to link to the JavaScript file. When the JavaScript code is in an external file, it can be cached on the client side and doesn’t need to be downloaded with every page.

Writing the JavaScript code inside the SCRIPT code and including the SCRIPT tag within HEAD or BODY increases the Web page’s size and causes the JavaScript code to be downloaded with each page request, thereby slowing down page loads.

Using the LINK tag will not work because it is used to link to the external CSS file.

The %= ... % construct is used to display values from ASP.NET code, such as a method call. Using the script tag is incorrect because this tag is used for defining class-level methods, properties, and variables.

The Inherits attribute in the @Page directive specifies a fully qualified name of the code-behind class from which the code should inherit. The Src attribute specifies the name of the source code file. The Codebehind attribute is used only by Visual Studio and is not used at runtime. The Classname attribute does not link ASP.Net pages with the code-behind class or file.
