Presentation Software.

vkungeLeave a comment

Presentation software is used to display information one slide at a time. The term “slide” can be thought of as a single poster used to display a small number of points or a single idea.  

Presentation software was made to mimic the behaviour of a traditional slide projector.

Many slides are displayed one at a time by the presenter. The presenter can include the following items on slides:

  • Text – including short points on the topic being presented.  Text is usually held within a Textbox.
  • Shapes – including pre defined  shapes e.g circle, square etc.
  • Images: users can insert downloaded images, or provided clip art.
  • Charts: the presentation software provides facilities for creating and inserting various chart types including bar, line, pie charts etc.
  • Animations – Objects can be set in motion on any slide. Objects include images, shapes, text boxes etc.
  • Transitions – Slides transform from one to the next in one smooth animation.

Example of presentation software are Microsoft Powerpoint  and Prezi.

The Selection Construct

vkungeLeave a comment

Sometimes we wish to change the order of processing based on certain conditions.

This can be accomplished by using a selection construct pictured below:

We will examine this in the following example:

Jim is a salesman for an auto car company. If his total sales for the week exceeds $10000 he is rewarded a sales commission of 8 percent of the sale, if not he is awarded no commission.

Create a flowchart algorithm which accepts the total sales and outputs the commission.

Exercise:

The problem is modified such that  if the total sales were less than $10000 he would receive a commission of 4 percent. See changes below:

Jim is a salesman for an auto car company. If his total sales for the week exceeds $10000 he is rewarded a sales commission of 8 percent of the total sales, if not he is awarded a commission of 4 percent.

Create a flowchart algorithm which accepts the total sales and outputs the commission.

Draw a flowchart for the modified scenario.

Algorithms In Narrative Form

vkungeLeave a comment

An algorithm in narrative form is not written in discrete steps.   It is expressed as directions in paragraph form and instructions on how rules should be followed.

An algorithm in narrative form can be considered a precursor to pseudocode or a flowchart

Example

An example is given below for the given problem statement

Problem Definition: A solution is needed which finds the circumference of a circle.

Algorithm in narrative form: Prompt the user to enter a non-negative value for the radius and store it. If the radius entered is negative or is not a number, keep on prompting the user and accept values until a suitable value is entered.  Use the formula C=2*3.14* r to calculate and store the circumference. Output the circumference to the user and stop processing.

In class exercise

Write an algorithm in narrative form which gives instructions/directions on how to follow the rules in order to play “Snakes and ladders”.

Threats to Computer and Data Security

vkungeLeave a comment

Recall that Software is a set of instructions that can be executed by a computer system. System software is used to maintain hardware resources, while application software solves end user problems.

There are, however, other categories of software which are meant to be malicious and disruptive to the computer system.

Homework

Search engines

vkungeLeave a comment

A search engine is website application that allows users to search for information on the world wide web.

Search engines are mainly accessed by their website address. When a user visits a search engine’s website address, they can input their search criteria (also known as a search query) so that the search engine may produce a list of website pages which contain information related to the search criteria.

e.g, a user may visit http://www.google.com and proceed to input the search criteria funny videos :

user enters the search query “funny videos”

Now they can click on the search button –

Click on the search button to perform the search.

And now you can view and visit web pages from various websites which contain related results:
