8 0

Answer:

Two Dutch spectacle-makers and father-and-son team, Hans and Zacharias Janssen, create the first microscope in 1590.

Explanation:

A microscope is an instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by the unaided eye. The most familiar kind of microscope is the optical microscope, which uses visible light focused through lenses. Eeuwenhoek observed animal and plant tissue, human sperm and blood cells, minerals, fossils, and many other things that had never been seen before on a microscopic scale. He presented his findings to the Royal Society in London, where Robert Hooke was also making remarkable discoveries with a microscope.

Write a method for the Invitation class that accepts a parameter and uses it to update the address for the event.
DerKrebs [107]

Answer:

public class Invitation {

 private String hostname;

 private String address;

  public Invitation(String n, String a) {  // constructor that accepts two strings.

   hostname = n;

   address = a;

 }

  public String getHostname() {

   return hostname;

 }

 public void setAddress(String a) {

   address = a;

 }  

 public String invite(String guest) {

   return "Hello" +guest+ ", you are invited to my party at " +address+". "+hostname+".";

 }

 public Invitation(String host, String address) {

   this.address = address;

   this.hostname = host;

 }

}

Explanation:

The Java program defines a class called "Invitation". The class constructor has two string arguments or parameters for the host of the event and the address. The invite method is used to generate the string invite message with the name of the guest as the argument. Use the "setAddress" method to set a new location of the event and the "getHostname" to get the name of the event host.

IRQ 0 interrupt have _______________ priority<br> ? low<br> ? medium<br> ? highest<br> ? lowest
tekilochka [14]

Answer:

Highest

Explanation:

A interrupt request / IRQ is in which instructions are sent to Cpu and uses an interrupt handler to run distinct program . Hardware interrupts are used to manage occurrences such as obtaining modem or network card information, important presses, or mouse motions.

  • Interrupt request 0. – it is a system timer (can not be altered)
  • Interrupt request 1 – keyboard controller (can not be changed)
  • Interrupt request 2 – cascaded IRQ 8–15 signals (any device configured to use IRQ 2 will genuinely use IRQ 9)
  • Interrupt request 3 – serial port 2 controller
  • Interrupt request 4 –  serial port 1 controller
  • Interrupt request 5 –parallel port 2 and 3
  •  Interrupt request 6 - floppy disk controller
  •  Interrupt request 7 –parallel port 1. If a printer is not present, it is used for printers or for any parallel port. It can also possibly be shared with a secondary sound card with cautious port management.

As interrupt number increases priority level decreases, Priority level 0 is the highest priority level .
