a) To determine the prefix to use, we need to calculate the number of bits needed to support the maximum number of networks and the minimum number of hosts per network. The minimum number of hosts per network is 500, which requires at least 9 bits (since 2^9 = 512). To support the maximum number of networks, we need to find the highest power of 2 that is less than or equal to the number of networks. In this case, 2^11 = 2048, so we need 11 bits for the network portion of the address. Therefore, the prefix to use is /27, since we're using 16 bits for the network portion of the address and 11 bits for the host portion (16 + 11 = 27).
b) The subnet mask to use for a /27 prefix is 255.255.255.224. This is because a /27 prefix uses the first 27 bits of the 32-bit address for the network portion, which leaves 5 bits for the host portion. Converting these 5 bits to decimal gives us 2^5 = 32, so each subnet has 32 addresses. Subtracting 2 from this (one address for the network and one address for the broadcast) gives us 30 usable addresses per subnet.
c) Using a /27 prefix, we can create up to 2048 (2^11) networks, each with up to 30 usable addresses. The first four networks would be:
Network Address Subnet Mask Usable Address Range Broadcast Address
80.0.0.0 255.255.255.224 80.0.0.1 - 80.0.0.30 80.0.0.31
80.0.0.32 255.255.255.224 80.0.0.33 - 80.0.0.62 80.0.0.63
80.0.0.64 255.255.255.224 80.0.0.65 - 80.0.0.94 80.0.0.95
80.0.0.96 255.255.255.224 80.0.0.97 - 80.0.0.126 80.0.0.127
Note that the network address and broadcast address are not usable for hosts, which is why we subtract 2 from the total number of addresses per subnet to get the number of usable addresses.

A. Write an application where the main method holds two double variables. Assign values to the variables. Pass both variables to a method named computePercent() that displays the two values and the value of the first number as a percentage of the second one. Save the file as Percentages.java. Example: If the numbers are 2.0 and 5.0 Output: 2.0 is 40 percent of 5.0.
B. Modify the program above (Percentages.java) to accept values of the two doubles in the main method from a user at the keyboard. Save the file as UserPercentages.java. Output: Enter in two numbers: 2.0 5.0 2.0 is 40 percent of 5.0
To read input from the keyboard, we first import the Scanner class in the changed code. The user is then prompted to enter two digits using a Scanner object that we construct and call input.
What would be the code for the program?The nextDouble() method is used to read in the numbers, which are then assigned to the num1 and num2 variables. Lastly, we use the same approach as before and provide these variables to the computePercent() method. The result should be the same as before, but instead of using hardcoded values, it should use the values given by the user.
public class Percentages {
public static void main(String[] args) {
double num1 = 2.0;
double num2 = 5.0;
computePercent(num1, num2);
}
public static void computePercent(double num1, double num2) {
double percent = (num1 / num2) * 100;
System.out.println(num1 + " is " + percent + " percent of " + num2);

Describe the first generation of computer based on hardware, software, computer characteristics, physical appearance and their applications?
Answer:
The first generation of computers was developed in the 1940s and 1950s, and was characterized by the use of vacuum tubes as the primary component of their electronic circuits. These computers were large, expensive, and required a lot of power to operate. Here are some key characteristics of first-generation computers:
Hardware: First-generation computers used vacuum tubes for logic circuitry, which were large, fragile, and generated a lot of heat. They also used magnetic drums or tape for data storage.
Software: Early computer programming languages were developed during this time, including machine language and assembly language. Programs were written on punched cards or paper tape and fed into the computer by operators.
Computer characteristics: First-generation computers were slow and had limited memory capacity. They were also very expensive and often required specialized operators to use them.
Physical appearance: First-generation computers were large and took up entire rooms. They consisted of racks of electronic equipment, with wires and tubes connecting everything together. The user interface was typically a console with switches and lights.
Applications: First-generation computers were primarily used for scientific and military applications, such as calculating missile trajectories or decrypting codes. They were also used in business for accounting and payroll purposes.
Some examples of first-generation computers include the ENIAC (Electronic Numerical Integrator and Computer), UNIVAC (Universal Automatic Computer), and IBM 701. Despite their limitations, these early computers represented a major milestone in the development of computing technology and laid the foundation for future generations of computers.
