Which of the following statements is false? a. InputStream and OutputStream are abstract classes for performing byte-based I/O.

b. Tubes are synchronized communication channels between threads. c. A filter stream provides additional functionality, such as aggregating data bytes into meaningful primitive-type units. FilterInputStream and FilterOutputStream are typically extended, so some of their filtering capabilities are provided by their concrete subclasses. d. A PrintStream performs text output. System.out and System.err are PrintStreams.

Answer:

The answer is "Option b".

Explanation:

Tubes were streams among processes, that are interconnected. It is coordinated ways to communicate between threads, that's why the only option b is wrong, and the correct choice can be defined as follows:

  • In option a, the byte-based I/O the input and output stream abstract class is used, that's why it correct.
  • In option c, It is used to provide additional functionality, that's why it correct.  
  • In option d, It is used to provide the text output.

Answer:

1) performance assessments

2) measurable goals

3)can't be measured quantitatively

4) milestones

Explanation:

Methods of evaluating the performance and productivity of an individual or group in relation to predetermined criteria and measurable goals are <u>performance assessments.</u>

<u>measurable goals</u> are goals that have concrete criteria for measuring progress toward their attainment.

Why are statements like “great customer experience” or “more sales” not good assessment criteria? <u>can't be measured quantitatively</u>

Personal goal setting helps lagging performance by setting <u>milestones</u>

which are short-term achievable tasks.
