List and define four sources of data errors.
(80) VerifiedSources of data errors include appending,truncating,transcripting,and transposing.Appending is the addition of extra characters to a field.Losing characters from a field is called truncating.Transcripting is defined as entering invalid data into a field.Transposing involves reversing the sequence of one or more characters in a field.
Briefly define ten validation tests and techniques used to enhance the validity of data input.
(82) VerifiedThe ten validation tests and techniques are: Class or composition,combinations,expected values,missing data,pictures/templates,range,reasonableness,self-checking digits,size,and values.The class or composition test checks to assure that data are of proper type.The combinations test checks to see if the value combinations of two or more data fields are appropriate or make sense.The expected values test checks to see if data are what is expected.The missing data test checks for existence of data items in all fields of a record.The picture/templates test assures that data conform to a standard format.The range test assures that data are within a proper range of values.The reasonableness test assures that data are reasonable for a situation.The self-checking digits test is a test where an extra digit is added to a numeric field in which its value is derived using a standard formula.Testing for too few or too many characters is referred to as a size test.A values test checks to make sure values come from a set of standard values.

(80) "Submenus should be used to break up exceedingly long menus," falls under which category for menu design guidelines?
(81) Which menu-positioning method places the access point of the menu near the top line of the display; when accessed,menus open by dropping down onto the display?
(93) "Reversing the sequence of one or more characters in a field," is related to transcripting data error type.
(71) Providing status information during processing operations is especially important if the operation takes longer than a second or two.
(77) Which test is done to ensure that data conform to a standard format?
