Understanding hypermedia

  1. 1.  Hypermedia includes more than one media: Text Graphics Audio Animation Video clips
  2. 2.  Since only virtual learning activity takes place, it is important from the standpoint of the teacher to optimize the learning process by identifying the characteristics of media application, as well as the advantages and limitations of such an application.
  3. 3.  Given all its capabilities, hypermedia still does not replace life’s experiences and learning from nature and life.  This saying that information and communication technology cannot replace the teacher altogether.  Note that even technologists admit that the computer has an IQ of zero and depends on what man can input or make of it.  GIGO or garbage in, garbage out is the very first principle that should be remembered about the computer.
  4. 4.  Stands for "Garbage In, Garbage Out." GIGO is a computer science acronym that implies bad input will result in bad output.  Because computers operate using strict logic, invalid input may produce unrecognizable output, or "garbage." For example, if a program asks for an integer and you enter a string, you may get an unexpected result. Similarly, if you try to open a binary file in a text editor, it may display unreadable content.  GIGO is a universal computer science concept, but it only applies to programs that process invalid data. Good programming practice dictates that functions should check for valid input before processing it. A well-written program will avoid producing garbage by not accepting it in the first place. Requiring valid input also helps programs avoid errors that can cause crashes and other erratic behavior.  NOTE: Because the related terms FIFO and LIFO are pronounced with a long "i," GIGO is typically pronounced "guy-go" (not gih- go). This also helps avoid confusion with the prefix "giga," which is pronounced with a soft "i."
