A computer system is a combination of hardware and software components that work together to perform various tasks and process data. It typically includes a central processing unit (CPU), memory, storage devices, input/output devices, and operating system software.

Different application domains of computer systems include:

1. Business and Finance: Used for accounting, payroll, inventory management, and financial analysis.

2. Education: Applied in e-learning, educational software, student record management, and research.

3. Healthcare: Utilized for patient records, medical imaging, telemedicine, and clinical decision support systems.

4. Entertainment: Includes video games, multimedia content creation, streaming services, and social media platforms.

5. Manufacturing and Industry: Used for process control, robotics, supply chain management, and quality control.

6. Communication: Includes email, instant messaging, video conferencing, and social networking.

7. Science and Engineering: Applied in simulations, data analysis, modeling, and research.

These application domains demonstrate the versatility and widespread use of computer systems across various sectors for enhancing productivity, efficiency, and innovation.

To create a "hospital database" using MS-Access, we'll make the following assumptions for designing the database:

1. Entities:

   • Patients: Information about patients including their ID, name, date of birth, gender, contact details, and medical history.
   • Doctors: Details of doctors including their ID, name, specialization, contact information, and schedule.
   • Appointments: Records of appointments between patients and doctors, including appointment ID, patient ID, doctor ID, appointment date, and time.
   • Medical Records: Information about medical procedures, diagnoses, medications, and treatments associated with each patient's visit.
   • Departments: Details of different medical departments within the hospital, such as cardiology, pediatrics, orthopedics, etc.

2. Relationships:

   • Patients can have multiple appointments with different doctors over time, establishing a one-to-many relationship between Patients and Appointments.
   • Doctors can be associated with multiple appointments and may belong to one or more departments, establishing a many-to-many relationship between Doctors and Appointments, and a many-to-many relationship between Doctors and Departments.
   • Each appointment is associated with one patient and one doctor, establishing one-to-many relationships between Appointments and Patients, and between Appointments and Doctors.
   • Each medical record is associated with one patient and contains details of medical procedures, diagnoses, medications, and treatments, establishing a one-to-many relationship between Patients and Medical Records.

3. Tables:

   • Patients Table: Fields include PatientID, Name, DateOfBirth, Gender, ContactNumber, MedicalHistory.
   • Doctors Table: Fields include DoctorID, Name, Specialization, ContactNumber, Schedule.
   • Appointments Table: Fields include AppointmentID, PatientID, DoctorID, AppointmentDate, AppointmentTime.
   • Medical Records Table: Fields include RecordID, PatientID, Procedure, Diagnosis, Medication, Treatment.
   • Departments Table: Fields include DepartmentID, DepartmentName.

4. Data Integrity:

   • Implement primary keys for each table to ensure uniqueness and establish relationships between tables.
   • Use foreign keys to maintain referential integrity between related tables.
   • Apply data validation rules to ensure data accuracy and consistency.

By following these assumptions and designing the database accordingly, we can effectively manage hospital-related data in MS-Access.

Here's a C program that prompts the user with the given options and performs the corresponding actions after taking input from the user:

#include <stdio.h>

// Function to compare two numbers and return the larger one
int compareNumbers(int num1, int num2) {
    return (num1 > num2) ? num1 : num2;
}

// Function to check if a number is prime
int isPrime(int num) {
    if (num <= 1) {
        return 0; // Not prime
    }
    for (int i = 2; i * i <= num; i++) {
        if (num % i == 0) {
            return 0; // Not prime
        }
    }
    return 1; // Prime
}

int main() {
    int choice, num1, num2;

    // Prompt user with options
    printf("Choose an option:\n");
    printf("1) Compare two numbers for the larger\n");
    printf("2) Test a number for prime or not\n");
    printf("Enter your choice (1 or 2): ");
    scanf("%d", &choice);

    switch (choice) {
        case 1:
            // Input two numbers
            printf("Enter two numbers: ");
            scanf("%d %d", &num1, &num2);
            // Compare and print the larger number
            printf("The larger number is: %d\n", compareNumbers(num1, num2));
            break;
        case 2:
            // Input a number
            printf("Enter a number: ");
            scanf("%d", &num1);
            // Check if the number is prime and print the result
            if (isPrime(num1)) {
                printf("%d is a prime number.\n", num1);
            } else {
                printf("%d is not a prime number.\n", num1);
            }
            break;
        default:
            printf("Invalid choice. Please enter 1 or 2.\n");
    }

    return 0;
}

This program prompts the user with options to compare two numbers for the larger or test a number for being prime. After the user chooses an option, it asks the user to enter the required numbers and performs the corresponding operation.
