When replacing a system board in a laptop, which feature is a must?
Marta_Voda [28]

Answer:

Having the integrated peripherals in the same locations as the old system board

Explanation:

System board is the printed circuit board that is used to connect the peripheral devices. It provides the slots and ports to connect the peripherals devices.

If there is a need to replace the system board of the laptop. You can change the system board. On new system board, all the peripherals that are installed on previous (old) system board should be placed on new system board. As the system requirements are same, only printed circuit board of the system is changed.

The new system board is replica of the previous board so, we can not change peripheral of the system boards.

For this programming assignment, you have to write a Java program that tests whether a given input string represents a Valid E-m
Step2247 [10]

Answer:

To check if the email address is correct it should have only one "@" symbol, we have to split the input string by this symbol. The code in java to achieve this is the following:

class Main {

 public static void main(String[] args) {

   String email = "[email protected]";

   String[] email_split = email.split("@");

   long count_a = email.chars().filter(ch -> ch == '@').count();

   if(count_a == 1){

     System.out.println("User name:   "+email_split[0]);

     System.out.println("Domain name: "+email_split[1]);

   }else{

     System.out.println("There is no valid email address.");

   }

 }

}

Explanation:

The explanation of the code is given below:

class Main {

 public static void main(String[] args) {

   String email = "[email protected]"; //input string to evaluate if is valid email

   long count_a = email.chars().filter(ch -> ch == '@').count(); //Count how many times the symbol @ appears

   if(count_a == 1){ //A valid email only contains one at

     String[] email_split = email.split("@"); //separate the values using the at in an array

     System.out.println("User name:   "+email_split[0]); //the first element is the username

     System.out.println("Domain name: "+email_split[1]); //the second element is the domain name

   }else{

     System.out.println("There is no valid email address."); //If there isn´t an at or are more than one then display a message saying the email is not valid

   }

 }

}

____ gets its name from the notion that it ignores the traditional A, B, and C class designations for IP addresses and can there
Sedbober [7]

<u>Classless Inter-Domain Routing</u> gets its name from the notion that it ignores the traditional A, B, and C class designations for IP addresses and can therefore set the network-host ID boundary wherever it wants to, in a way that simplifies routing across the resulting IP address spaces.

<u>Explanation</u>:

A router is a networking device that helps in connecting multiple networks. <em><u>Classless Inter-Domain Routing (CIDR) </u></em>is used for creating IP addresses and IP routing. CIDR was introduced in the year 1993 by <em><u>“The Internet Engineering Task Force”</u></em>. The classful network design was replaced by CIDR in the Internet.

The IP addresses are responsible for sending the particular information packets to specific computers. Classless inter-domain routing helps in improving the allocation of IP addresses.
