What is one major component that would not be found in a tablet or phone, and how has modern computing made that component less
IRISSAK [1]

Answer:

A hard drive

Explanation:

Since tablets and phones are compact, they are better off not having a big, giant, bulky storage device like hard drives. Modern computing made hard drives less important by developing Solid-State Drives (SSDs) and extremely dense (512 bit) storage that can provide the same if not more storage than a traditional hard drive at the fraction of the size.

Write java code to create a new class called "student". an object of the student class has attributes like student id, name and
Fiesta28 [93]
Here you go. I added a constructor and a toString overload to make the object creation and printing as easy as possible.

public class student {
    private String _id;
    private String _name;
    private String _address;

    public student(String id, String name, String address) {
        _id = id;
        _name = name;
        _address = address;
    }

    public String toString() {
        return "Id: " + _id + "\nName: " + _name + "\nAddress: "+ _address;
    }

    public static void main(String[] args) {
        student s1 = new student("S12345", "John Doe", "Some street");
        System.out.println(s1);
    }
}
