Answer:

To make sure that data sent from a device is just received by appropriate device we use "<u>Switch</u>"

Explanation:

Switch is the networking device. It is used to connect all the Local area networks in a computer network. The switch store the addresses of all computers over the network. Whenever data packet arrives to the switch, it just read the address of destination computer and just send it to appropriate device instead of all devices.

Hub is also used for this purpose, but it has no ability to read the address and send the packet to all devices over the network.

<em>So, we use Switch to send data to appropriate device.</em>

The remove() method in the Queue interface ________. Group of answer choices retrieves, but does not remove, the head of this qu

salantis [7]

<h2>Question:</h2>

The remove() method in the Queue interface ________.

A. retrieves, but does not remove, the head of this queue, returning null if this queue is empty

B. retrieves and removes the head of this queue, or null if this queue is empty

C. retrieves, but does not remove, the head of this queue, throwing an exception if this queue is empty

D. retrieves and removes the head of this queue and throws an exception if this queue is empty

<h2>Answer:</h2>

D. retrieves and removes the head of this queue and throws an exception if this queue is empty

<h2>Explanation:</h2>

In Java, the Queue interface is found in the java.util package and inherits from the Collection interface. It is used to store elements which are processed in the order in which they are inserted. This means that the first element will be processed first.

The Queue interface has many methods. Some of them are;

i. add(): allows elements to be added to the queue.

ii. remove(): retrieves and removes elements from the head of the queue. The head of the queue points to the first element of the queue. If the queue is empty, the remove() method throws an exception called the <em>NoSuchElementException</em>

<em />

iii. poll(): retrieves and removes the element at the head of the queue. Unlike the remove() method, if the queue is empty, a <em>null </em>is returned.

iv. peek(): retrieves but does not remove the element at the head of the queue. Just like the poll() method, a <em>null</em> is returned if the queue is empty.
