The hardware requirements of WANs are designed to provide reliable connectivity, efficient data transmission, enhanced security, and optimized network performance across wide geographic areas.
Some of the key uses of hardware requirements in WANs are as follows:
Routers: Routers play a crucial role in WANs by connecting different networks and directing traffic between them. They require robust hardware capabilities to handle high data throughput, advanced routing protocols, and secure VPN connections.
Switches: Switches are responsible for connecting multiple devices within a network. In WANs, switches with high port density and enhanced features like VLAN support and Quality of Service (QoS) are necessary to manage network traffic effectively.
Modems: Modems are used to convert digital signals into analog signals for transmission over telephone lines or cable networks. WANs often require specialized modems that support the specific communication technologies used, such as DSL or cable modems.
Firewalls: Firewalls are critical for securing WAN connections and protecting the network from unauthorized access and threats. Hardware firewalls offer dedicated processing power and advanced security features like intrusion prevention and VPN capabilities.
Load Balancers: In WANs with multiple connections or links, load balancers distribute network traffic across these links to optimize performance and ensure high availability. They require robust hardware to handle heavy traffic loads and perform intelligent traffic distribution.
Overall, hardware requirements for Wide Area Networks (WANs) are essential to ensure efficient and reliable network connectivity over large geographical areas.

Student(sid, sname, year)
Registered(sid, cid, mark, grade)
Course(cid, cname, no_credit, deptid)
Which of the following sequence of operations would list the names of students who have not registered for any course?
To list the names of students who have not registered for any course, we can use the following sequence of operations:
Retrieve all student IDs (sid) from the Student table.Retrieve all student IDs (sid) from the Registered table.Perform a LEFT JOIN between the two sets of student IDs, filtering out the matching records.Retrieve the names (sname) of the students from the resulting set.How can we list the names of students who have not registered for any course?To obtain the names of students who have not registered for any course, we need to compare the student IDs between the Student and Registered tables.
By performing a LEFT JOIN and filtering out the matching records, we will be left with the students who have not registered for any course. Finally, we can retrieve their names from the resulting set to list them.

What is string?
A string is typically a sequence of characters in computer programming, either as a literal constant or as some sort of variable. The latter can either be fixed or its elements and length can be changed (after creation). A string is typically implemented as just an array data structure of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding. A string is generally thought of as a type of data. A string can also represent other sequence(or list) data types and structures, such as more general arrays. A variable declared to be a string may cause memory storage to be statically allocated for just a predetermined maximum length or utilise dynamic allocation to allow this to hold a variable number of elements, depending on this same programming language and specific data type used.

The program below is a salary calculator. It need to be modified to substract 30% to account for taxes, and 8% for retirement from the gross. Then print out the net amount earned.
import java.util.Scanner;
public class Salary {
public static void main(String [] args) {
Scanner scnr = new Scanner(System.in);
int hourlyWage;
int weeklyHours;
int weeklySalary;
int overtimeHours;
final int WEEKLY_LIMIT = 40;
System.out.println("Enter hourly wage: ");
hourlyWage = scnr.nextInt();
// FIXME: Get user input value for weeklyHours
weeklyHours = 40;
if (weeklyHours <= WEEKLY_LIMIT) {
weeklySalary = weeklyHours * hourlyWage;
}
else {
overtimeHours = weeklyHours - WEEKLY_LIMIT;
weeklySalary = (int)((hourlyWage * WEEKLY_LIMIT) +
(hourlyWage * overtimeHours * 1.5));
}
System.out.print("Weekly salary is: " + weeklySalary);
}
}
Here's how we can modify the program:
import java.util.Scanner;
public class Salary {
public static void main(String [] args) {
Scanner scnr = new Scanner(System.in);
double hourlyWage;
int weeklyHours;double grossPay;
double netPay;
int overtimeHours;
final double TAX_RATE = 0.3;
final double RETIREMENT_BENEFITS = 0.08;
final int WEEKLY_LIMIT = 40;
System.out.println("Enter hourly wage: ");
hourlyWage = scnr.nextDouble();
System.out.println("Enter weekly hours: ");
weeklyHours = scnr.nextInt();
if (weeklyHours <= WEEKLY_LIMIT) {
grossPay = weeklyHours * hourlyWage;
}
else {
overtimeHours = weeklyHours - WEEKLY_LIMIT;
grossPay = (hourlyWage * WEEKLY_LIMIT) +(hourlyWage * overtimeHours * 1.5);
}
netPay = grossPay - (grossPay * TAX_RATE) - (grossPay * RETIREMENT_BENEFITS);
System.out.println("Net pay is: " + netPay);
}}
In the above modified program, we have changed the datatype of hourlyWage, grossPay, and netPay to double as it's always better to use double for financial calculations.We have added two more variables TAX_RATE and RETIREMENT_BENEFITS which will be used to calculate the taxes and retirement benefits.The user can now input the weekly hours.
The program will calculate the gross pay using the formula Gross Pay = Hourly Wage * Weekly Hours.If weekly hours are less than or equal to the weekly limit, we calculate the gross pay using the formula Gross Pay = Weekly Hours * Hourly Wage.
Otherwise, we will calculate the overtime hours, and use the formula Gross Pay = (Hourly Wage * Weekly Limit) +(Hourly Wage * Overtime Hours * 1.5).Finally, we calculate the net pay using the formula Net Pay = Gross Pay - Taxes - Retirement Benefits. The program then prints out the net amount earned.
