Answer:

Explanation:

The correct answer is none of these

An operating system that allows a single user to perform only one task at a time is called a Single-User Single-Tasking Operating System. Functions like printing a document, downloading images, etc., can be performed only one at a time. Examples include MS-DOS, Palm OS, etc.

Advantage: This operating system occupies less space in memory.

Disadvantage: It can perform only a single task at a time.

There are four types of operating systems −

Real-time operating system

Single-User/Single-Tasking operating system

Single-User/Multitasking operating system

Multi-User/Multitasking operating system

Real-time operating system is designed to run real-time applications. It can be both single- and multi-tasking. Examples include Abbasi, AMX RTOS, etc.

An operating system that allows a single user to perform more than one task at a time is called Single-User Multitasking Operating System. Examples include Microsoft Windows and Macintosh OS.

It is an operating system that permits several users to utilize the programs that are concurrently running on a single network server. The single network server is termed as "Terminal server". "Terminal client" is a software that supports user sessions. Examples include UNIX, MVS, etc.

Unit 6: Lesson 2 - Coding Activity 1 AP Computer science

sladkih [1.3K]

The complete program is to define a boolean method that returns true if all elements of an array are negative, or return false, if otherwise

The method in java, where comments are used to explain each line is as follows:

//This defines the method

public static boolean chkNegative (double[] myArr) {

//This initializes a boolean variable

boolean isNeg = true;

//This iterates through the array

for (int i = 0; i < myArr.length; i++) {

//If the array element is 0 or positive

if (myArr[i] >= 0) {

//Then the boolean variable is set to false

isNeg = false;

//And the loop is exited

break;

}

//This returns true or false

return isNeg;

}
