In this issue, we focused on how the ever-changing dynamics of the marketplace put new demands on IT and business managers—requiring they stay nimble and creative to keep pace. So even after a successful project launches, the best leaders are looking to the horizon to identify new challenges and opportunities.

And they expect that the IT systems that support them will reflect their needs. Business processes enshrined in core enterprise resource functionality must match the expectations of customers and partners. IT access points must address the needs of actual users.

Continuous improvement must be a philosophy shared across the organization. And any long-term IT strategy must have flexibility and scalability in its very DNA.

MC9224 - System Software - Unit 5 - Question Bank

Text editor and system software, debugger

 1.      What is Text Editor?

            At its most basic, a text editor is a tool for simply editing text. You can use a text editor for a wide variety of tasks from cleaning up data to editing configuration files on your system.

2.      Who does mostly use a text editor?

1. Programmers and Secretaries of authors.
2. Knowledge workers (who compose, organize, study and manipulate the computer-based information)

3.      What are your first thoughts about how to build a document editor?

1. Internal structure
2. Formatting
3. GUI
4. Spell Check

4.      What is CLI?

Command Line Interface(CLI) is an interface used to the user interacts with the computer through the commmand languages and also used to configure most servers, Routers and so on.

 

5.      What is an Interactive Editor?

An Interactive Editor is a computer program that allows a user to create and revise a target document.

6.      What are the contents of a document?

1. Computer programs
2. Text information
3. Equations
4. Tables
5. Line art and
6. Photographs

7.      Listout the set of operations of the actual editing phase.

The actual editing phase has the set of operations such as Insert, Delete, Replace, Move and Copy.

8.      What are the four tasks of the overview of editing process? Or Write the tasks accomplished by the document editing process.

The document-editing process is an interactive user-computer dialogue to accomplish four tasks:

1. Select the part of the target document to be viewed and manipulated.
2. Determine how to format this view on-line and how to display it.
3. Specify and execute operations that modify the target document.
4. Update the view appropriately.

9.      List out the user interface editors?

1. Interactive Editors
2. Line Editors
3. Screen Editors

10.  List the categories of user interface input devices.

1. Text devices
2. Button Devices
3. Locator devices

11.  List the categories of user interface Output devices.

1. Teletype Writers
2. Character-printing terminals
3. Glass teletypes
4. Modern professional workstations.

12.  List the categories of user interface interaction language.

1. Typing-Oriented or Text Command oriented. [Eg: Unix editors]
2. Function-Key editor. [eg: ‘C’ editor]
3. Menu-oriented user interface or Icons. [eg: Windows editors]

13.  What are the components of the editing structure?

1. Editing Component
2. Traveling Component
3. Viewing Component
4. Display Component
5. Filter Component

14.  What is an Interactive debugging system?

An Interactive Debugging System provides programmers with facilities that aid in the testing and debugging of programs.

15.   What are the functions of the Interactive debugging system?

1. Debugging functions and capabilities
2. Relationship with other parts of the system.
3. User Interface criteria.

16.  Define: Gaits.

Given a good graphical representation of program progress, it may even be useful to run the program at various speeds, called gaits.

 

17.  Define: Trace or Tracing. Or What is Tracing?

Tracing can be used to trace the flow of execution logic and data modifications.

 18.   Define: Traceback.

Traceback can show the path by which the current statement was reached. It can also show which statements has modified a given variable or parameter. This kind of information should be displayed symbolically and related to source program.

19.  What is Debugging?

It is the process of isolating and correcting the causes of the known errors in a program.

20.  List out the various system software tools.

1. Database Management Systems
2. Text Editors
3. Interactive Debugging Systems
4. Operating System
5. Compilers

21.  What is the importance of the user interface?

The user of an interactive editor is presented with a conceptual model of the editing system. This model provides an easily understood abstraction of the target document and its elements, with a set of guidelines describing the effects of operations on these elements.

22.  How the mapping of view buffer to a window is done?

The mapping of the viewing buffer to a window is accomplished by two components of the system.

1. the viewing component formulates an ideal view, often expressed in a device-independent intermediate representation.
2. the display component takes this idealized view from the viewing component and maps it to a physical output device in the most efficient manner possible.

23.  What is a Locator device?

The Locator devices are two-dimensional analog-to-digital converters that position a cursor symbol on the screen by observing the user’s movement of the device.
