Which of the following operations are considered to be crucial tasks that should be performed before installing server roles and

Bas_tet [7]

Answer:

A. Static IP address have been configured.

Explanation:

A network is an interconnection of network devices for communication to occur. A network comprises of end devices and intermediate network devices.

End devices are the sources and destinations of data transmission, while intermediate devices are the devices that makes communication of data possible like routers and switches. Examples of end devices are servers and workstations (computers, smartphones etc.).

A server in a network is a device that provides special services to workstations or clients. The IP addresses of servers must be known, that is, a static IP address must be configured on a server. Examples of server protocols are DNS, TFTP, FTP, DHCP etc.

A laptop computer has two internal signals: An unplugged signal, which is '1' if the laptop's power supply is connected, and '0'

Brums [2.3K]

Answer:

The correct usage is a NOR gate which is indicated in the explanation.

Explanation:

The truth table for the given two signals, namely

p=unplugged signal

q=low battery signal

can form a truth table of following form

Here p has 2 states

1 if the power supply is connected

0 otherwise

Similarly q has 2 states

0 if the battery has reached almost zero state

1 otherwise

As the condition for the Hibernate Signal is given as to only activate when the battery is low and the power supply is not connected. This indicate that the value of Hibernate signal should be 1 when both p and q are 0.

Using this condition, the truth table is formed as

unplugged signal | low battery signal | Hibernate Signal

0 | 0 | 1

0 | 1 | 0

1 | 0 | 0

1 | 1 | 0

Now the truth table of NOR is given as

a | b | a or b | ~(a or b)

0 | 0 | 0 | 1

0 | 1 | 1 | 0

1 | 0 | 1 | 0

1 | 1 | 1 | 0

This indicates that the both truth tables are same thus the NOR gate is to be used for this purpose.

Marina86 [1]

Answer:

I am writing a C++ and JAVA program.

import java.util.Scanner; //for using input output functions

public class LabProgram { // class name

public static void main(String[] args) {//start of main function body

Scanner input = new Scanner(System.in);

// creates input instance of Scanner type

String str; // declares String type variable str for a string value

int num; // declares integer type variable num to hold an integer value

str = input.next(); //scans and reads input string from user

num = input.nextInt(); //scans and reads input integer from user

//while loop continues to execute until user enters quit 0

while(str!="quit" && num!=0) {

/* prints the following message, for example if value of num = 2 and value of str = apples then the following print statement prints Eating 2 apples a day keeps the doctor away. */

System.out.println("\nEating " + num +" " + str + " a day keeps the doctor away.");

//takes string and integer as input again and keep taking input until user //enters quit 0

str = input.next();

num = input.nextInt(); } } }

Explanation:

The program is well explained in the comments mentioned with each statement of the program. The program simply prompts user to enter a string and an integer. The while loop keeps executing until user enters quit 0. The program keeps taking input string and integer from user and prints the message System.out.println("\nEating " + num +" " + str + " a day keeps the doctor away."); The loop breaks when the use enters quit 0. The screenshot of the program along with its output is attached.
