  A. Loop

  B. Variable

  C. Constant

  D. Function

  Correct Answer: B

  A variable contains a value that can change during the execution of the program. This value might be a text string, a number, or any other data type.

  Note...Variables are usually declared, defined as a particular data type, and given an initial value at the start of the routine in which they are used. It is often possible to use undeclared variables, but this can make code harder to read and

  more prone to errors.

• Question 367:

  Which of the following statements BEST describes binary?

  A. A notational system used to represent an “on” or “off” state

  B. A notational system used to represent media access control

  C. A notational system used to represent Internet protocol addressing

  D. A notational system used to represent a storage unit of measurement

  Correct Answer: A

  While people find decimal easy to use, computers use binary to calculate and process information. Binary is a numbering system where each single digit can express only two values, in the range 0 to 1. The reason binary works well with computers is that these two values can represent the off/on states of the transistors that make up computer memory. Binary can also be referred to as base 2.

• Question 368:

  A systems administrator wants to return results for a time range within a database. Which of the following commands should the administrator use?

  A. SELECT

  B. INSERT

  C. DELETE

  D. UPDATE

  Correct Answer: A

  Data Manipulation Language (DML) commands allow you to insert or update records and extract information from records for viewing (a query):

  INSERT INTO TableName—adds a new row in a table in the database.

  UPDATE TableName—changes the value of one or more table columns. This can be used with a WHERE statement to filter the records that will be updated. If no WHERE statement is specified, the command applies to all the records in the

  table.

  DELETE FROM TableName—deletes records from the table. As with UPDATE, this will delete all records unless a WHERE statement is specified.

  SELECT—enables you to define a query to retrieve data from a database.
