Chapter 1 : Introduction to computers and Java

In modern computer systems, a byte consists of bits.

When a program runs on a computer, the part of the computer that carries out the instructions is called the

CPU

Which of these is not a programming language?

HTML

What best defines a "programming language"?

It allows us to express an algorithm.

Which statement is NOT true:

Machine languages can be used to write programs that can run on any machine.

When a program runs on a computer, it is stored in .

RAM

Which of the following is true?

There are no language rules regarding statements and line in general.

A bit is

a binary digit, like 0 or 1.

A byte in memory is identified by a unique number called its .

address

At each step of its operation, the input to a Central Processing Unit is

an instruction

An error in a program that involves a violation of language rules will be detected at time.

compile

Mice, trackpads, keyboards, scanners, joysticks are all examples of devices.

input

Files containing Java code must end with what "extension"? .

java

To run a Java program from a command line, we use the command.

java

The standard name of the Java compiler is .

javac

Words that have a special meaning in a programming language are called .

key words

The purpose of testing a program with different combinations of data is to expose run-time and errors.

logical

When a program is not running, it is stored

on a disk.

Monitors, printers, status lights are all examples of devices.

output

The ability of a language to let a programmer develop a program on computer system that can be run on other systems is called .

portability

Division by zero when the program is executing is an example of a error.

runtime

Flash drives, CDs, external disks are all examples of storage (memory) devices.

secondary

Carrying out the steps of a program, starting with the first, then the second and proceeding to the last is known as processing.

sequential

The code that a programmer writes is called code.

source

The rules that govern the correct order and usage of the elements of a language are called the of the language

syntax

A compiler

translates source code into executable code

A location in memory used for storing data and given a name in a computer program is called a because the data in the location can be changed.

variable

RAM, random-access memory, is called that because

you can pick any two random locations and it will take the same time to access the data.
