IV. Short Answer

  1. How is a compiler different from an interpreter?
    • A compiler is a separate program that converts the entire source program into machine language before executing it. Interpreter is a program used to convert a source program into machine language and then executes the machine language instructions.

    What is the advantage, and disadvantage, of an interpreter?

    • The advantage of an interpreter is that when it finds errors, it displays feedback immediately. The programmer can correct any errors before the interpreter translates the next line of code. The disadvantage is that interpreted programs do not run as fast as compiled programs. This is because an interpreter must translate the source program to machine language each time the program executes. Once a program is compiled, by contrast, users simply execute the object code to run the program.
  2. What is a major benefit of OOP?
    • The major benefit of OOP is the ability to reuse and modify existing objects.

    How is RAD (rapid application development) used for developing software?

    • RAD is a method for developing software. RAD used to writes and implements a program in segments instead of waiting until the program is completed.

    • Tools for building graphical user interfaces, an editor for entering program code, a compiler and/or interpreter, and a debugger.

    Describe the programming languages in the Visual Studio suite.

    • Visual Basic is a programming language that allows programmers easily to build complex task-oriented object-based programs.
    • Visual C++ is a programming language based on C++. Not only is Visual C++ a powerful object-oriented programming language, it enables programmers to write Windows, Windows Mobile, and .NET applications quickly and efficiently.
    • Visual C# is a programming language that combines programming elements of C++ with an easier, rapid development environment.
  4. How is XML used?
    • The uses of XML is to separate the web page content from its format, allowing the web browser to display the content of a web page in a form appropriate for the display device.

    Describe two applications of XML.

    • RSS 2.0, stands for Really Simple Syndication, and ATOM, specifications that content aggregators use to distribute content to subscribers.
  5. Describe two activities performed by the programmer when documenting a solution.
    • The two activities are reviewing the program code, and reviewing all the documentation.

      First, programmers review the program for any dead code and remove it. Dead code is any program instructions that a program never executes.

      Next, programmers should run the program one final time to verify it still works. After reviewing the program code, the programmer gives the program and all of its documentation to the systems analyst. The documentation includes all charts, solution algorithms, test data, and program code listings that contain global and internal comments. The programmer should be sure all documentation is complete and accurate. This becomes especially valuable if the program requires changes in the future.

    Why is proper documentation important?

    • Proper documentation greatly reduces the amount of time a new programmer spends learning about existing programs.

    • A case diagram graphically shows how actors interact with the information system. An actor is the user / entity and the use case is function that actor can perform, while class diagram graphically shows classes and one or more lower levels, called subclasses, in a system. Lower levels (subclasses) contain attributes of higher levels (classes) in concept called inheritance.

IV. Short Answer

  1. How does resolution affect images displayed on a monitor?
    • Resolution is the number of horizontal and vertical pixels in a display device. High resolution uses a great number of pixels and provides a smoother, sharper, and clearer image. As the resolution is increased, some items on the screen appear smaller.

    How does resolution relate to the size of an LCD monitor or screen?

    • Resolution generally is proportional to the size of the device. For example, a widescreen 9-inch LCD monitor typically has a resolution of 1440 x 900, while a widescreen 22-inch LCD monitor has a resolution of 1680 x 1050.
  2. Describe some of the features of HDTV.

  3. What are two types of wireless printing technology?
    • Bluetooth printing and infrared printing

    4. How do they differ in how they communicate with a computer or other device?

    • With bluetooth, computer can transmit output to a printer via radio waves. The devices do not need to be aligned with each other. They can be at a distance under 30-foot range. With infrared, the devices use infrared light waves. Both device IrDA ports need to be lined up together.
  4. How does an ink-jet printer work?
    • An ink-jet printer forms characters and graphics by spraying tiny drops of liquid ink onto a piece of paper.

    5. What are the differences between dye-sublimation printers used by professionals as compared to home or small business users?

    • Professionals often use the printer for photographic quality purposes, and it would cost thousands of dollars with the images in a wide range of sizes. Home or small business users typically print images in only one or two sizes and are much slower than the professional counterparts. They are also less expensive / cheaper.
  5. What might be included with a surround sound system for a computer?
    • Center speaker, satellite speakers, and subwoofer.

    6. What is audio resolution and what are the three examples of audio resolution?

    • Audio resolution is the number of bytes that represent sound in a given time. It’s stated as a bit rate such as 8-bit, 16-bit, or 24-bit.
