ITGS - SUMMATIVE TASK               Due Date : 18-1-2013

Area of impact:  Health                              M.M 25

        People with disabilities can benefit greatly from a wide variety of IT resources. For example, a person who has been injured can still make use of a computer by using voice input. There is software available that allows a user to control a computer by means of spoken commands. It is also possible to dictate material which can then be saved as a word processed or text file. Such voice recognition software has much potential for helping students and others to perform their tasks. Before voice activated software can be used, the user must first “train” the system. One voice activated control system states in its documentation that it must be run on a computer with a processor of at least 1 GHz.

a) (i) Define the term GHz. [1] 

    (ii) Identify the component of the processor to which 1 GHz refers. [2]

(b) Describe two other hardware features that would be necessary for voice activated input.[6]

(c) Explain why the voice activated system must be trained before it can be used. [6]

(d) Discuss how voice activated systems and other IT resources can be of benefit to disabled people. [10 ]
