Java An Introduction to Problem Solving and Programming Chapter 1.1 (SELF-TEST QUESTIONS)

What are the two kinds of memory in a computer?

Main memory and Auxiliary memory

What is software?

Software is a program with a set of computer instructions.

What data would you give to a program that computes the sum of two numbers?

Really depends, with Java you will give it a java code to compile as for bytecode that is already ready to be used can use the bytecode to of 0's and 1's to compile the sum of two numbers.
Thus giving it two numbers would really depend on the type of coding your doing.

What data would you give to a program that computes the average of all the quizzes you have taken in a course?

All of the quizzes that you have done.

What is the difference between a program written in a high-level language, a program in machine language, and a program expressed in Java bytecode?

• program written in high-level code:
- high level code needs to a Interpreter to translate the high-level code to low-level code.

• Machine language:
- Machine language consists of 0's and 1's.

• Java bytecode:
- Java bytecode needs to be compiled by the JVM to be able to work with low-level code.
- The same Java code can be used on other devices as long as the other device can compile the Java code.

Is Java a high-level language or a low-level language?

High-Level language.

Is Java bytecode a high-level language or a low-level language?

Low-Level language

What is a compiler?

The compiler is a interpreter that that translate the high-level code of Java into low-level code for the machine to read/understand.

What is a source program?

A high level program that is a input for the compiler.

What do you call a program that translates Java bytecode into machine language instructions?

The compiler.
