 MEMORY DEVICES : 

 The main storage is the primary memory, and data and programs are stored in secondary memory. However, memory is not stored in the CPU, but the CPU would only be a mess of wires without it!

RAM (Random Access Memory) and ROM (Read Only Memory) are examples of primary storage. Secondary Storage Devices: Secondary storage is a memory that is stored external to the computer. ... Hard Disk, CD, DVD, Pen/Flash drive, SSD, etc, are examples of secondary storage.

Thus, Computer storage is of two types: ... RAM (Random Access Memory) and ROM (Read Only Memory) are examples of primary storage. Secondary Storage Devices: Secondary storage is a memory that is stored external to the computer. It is mainly used for the permanent and long-term storage of programs and data.

What is the energy conversion of solar water heaters?

Gelneren [198K]

A liquid-to-liquid heat exchanger uses a heat-transfer fluid that circulates through the solar collector, absorbs heat, and then flows through a heat exchanger to transfer its heat to water in a storage tank. Heat-transfer fluids, such as antifreeze, protect the solar collector from freezing in cold weather.

Why might an algorithm created to assist in hiring decisions be biased?

nika2105 [10]

Answer:

Previous decisions were flawed

Explanation:

An algorithm depends entirely on the data input into the system in the decision making process.

As such, when there are conclusions in the data set used by the algorithm for decision making which are distorted, such as the association of less individuals that drink and drive in the rich cities than can be found in poorer communities due to the presence of less bars uptown and as such drivers from uptown areas are given preference may include a bias that is due to conclusion on which the previous decisions were made and used in the algorithm which may have been flawed or need more detailed analysis

nydimaria [60]

Answer:

import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Please enter two characters: ");
String inputStr = input.nextLine();
if(inputStr.charAt(0) == 'B' || inputStr.charAt(0) == 'b'){
System.out.println("Biology");
}
else if(inputStr.charAt(0) == 'C' || inputStr.charAt(0)== 'c'){
System.out.println("Computer Science");
}
else if(inputStr.charAt(0) == 'I' || inputStr.charAt(0) == 'i')
{
System.out.println("Information Technology and Systems");
}
else{
System.out.println("Invalid major");
}
int num = Character.getNumericValue(inputStr.charAt(1));
if(num >= 1 && num <= 4){
switch (num){
case 1:
System.out.println("freshman");
break;
case 2:
System.out.println("sophomore");
break;
case 3:
System.out.println("junior");
break;
case 4:
System.out.println("senior");
break;
}
}
else{
System.out.println("Invalid year status");
}
}
}

Explanation:

The code consists of two main parts. The part 1 is to validate the input major and print out the major according to the input character (Line 10 -22). If the input character is not matched with the target letters, a message invalid major will be displayed.

The part 2 is to validate the year status to make sure it only fall within the range of 1-4 (Line 26 -45). If within the range, the program will display the year major accordingly. If not a message invalid year status will be displayed.
