Answer:
import java.util.Scanner;
class Main {
public static void main(String args[]) {
Scanner scan = new Scanner(System.in);
System.out.print("Enter a decimal value (0 to 15): ");
int num = scan.nextInt();
scan.close();
if (num < 0 || num >15) {
System.out.printf("%d is an invalid input\n", num);
} else {
System.out.printf("The hex value is %X\n", num);
}
}
}

Answer:
A. The song was saved using fewer bits per second than the original song.
Explanation:
A song can be recorded on the computer or any device ranging from bit rates 96 kbps to 320 kbps.
The lesser the bitrates the lesser the quality of the audio and when we increase the bit rates, the quality of the audio recorded gradually increases.
Bitrates of 128 kbps give us a radio like quality whereas when we use bitrates of 320 kbps we get very good or CD-like quality.
According to the scenario, the most appropriate answer is option A.
A(n) client exists a computer that requests and utilizes network resources from a(n) server.
<h3>
What is a computer network?</h3>
- A computer network is a collection of computers that share resources that are available on or provided by network nodes.
- The computers communicate with one another via digital links using standard communication protocols.
- These links are made up of telecommunication network technologies that are based on physically wired, optical, and wireless radio-frequency means and can be configured in a variety of network topologies.
- Nodes in a computer network can be personal computers, servers, networking equipment, or other specialized or general-purpose hosts.
- They can be identified by network addresses and have hostnames.
- Local-area networks (LANs) and wide-area networks (WANs) are the two basic network types.
- A(n) client exists a computer that requests and utilizes network resources from a(n) server.

Answer:
1. Supercomputers
Supercomputers are very expensive and very fast. They are the most powerful computers we have in the world.
Supercomputers are optimized to execute only a small number of programs. This makes it possible for them to execute these few programs at a very high speed. Due to their inhibiting cost, they are used in high-end places like in scientific research centers. The supercomputer consists of thousands of processors, allowing it to clock in at very high speeds measured by petaflops.
These computer types are also very large in size due to the numerous parts and components involved in their design.
A good example of a supercomputer is Tianhe-2, which is located in the National Supercomputer Center in Guangzhou, China. It features 3.12 million cores, allowing it to run at speeds of 33.86 petaflops.
2. Mainframe Computers
These are large and expensive computers that are capable of supporting thousands of users simultaneously. They are mostly used by governments and large organizations for bulk data processing, critical applications, and transaction processing. They are ranked below supercomputers.
3. Minicomputers
Minicomputers are mid-sized computers. In terms of size and power, they are ranked below mainframes. A minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.
The use of the term minicomputer has diminished since the introduction of microprocessors. These machines are now more commonly called midrange computers.
4. Microcomputers
A microcomputer, also known as a personal computer, is designed to be used by one user at a time. The term microcomputer relates to the microprocessor that is used for the purpose of processing data and instruction codes. These are the most common computer types since they are not very expensive
Stopping the car. Do not continue driving if your tire has failed or blown out. After you stop the car, call for roadside assistance. Remember, safety first when you're driving!
