Answer:

Each pixel in an image is made up of binary numbers. ... To create the picture, a grid can be set out and the squares coloured (1 – black and 0 – white). But before the grid can be created, the size of the grid needs be known. This data is called metadata and computers need metadata to know the size of an image.

If I have an Animal superclass with a Mammal subclass, both concrete and both having a method called eat() with identical signat
Katarina [22]

Answer:

(c) the dynamic type of reference will determine which of the methods to call.

Explanation:

Polymorphism in Object Oriented Programming typically means the same method name can cause different actions depending on which object it is invoked on. Polymorphism allows for dynamic binding in that method invocation is not bound to the method definition until the program executes.

So in the case of Animal superclass and Mammal subclass, both having a method called eat() with identical signatures and return types, depending on which reference, the correct method eat() will be called dynamically upon execution.

For example, if we have the following;

================================

<em>Mammal mammal = new Animal();</em>

<em>mammal.eat()</em>

================================

The eat() method that will be called is the one in the Mammal subclass.

However, if we have;

================================

<em>Animal animal = new Animal();</em>

<em>animal.eat()</em>

================================

The eat() method of the Animal superclass will be called.

Which type of attack cripples the network and prevents legitimate users from accessing network resources
yaroslaw [1]

Answer:

A Distributed Denial of Service (DDoS) attack is a non-intrusive internet attack made to take down the targeted website or slow it down by flooding the network, server or application with fake traffic. When against a vulnerable resource-intensive endpoint, even a tiny amount of traffic is enough for the attack to succeed.

Distributed Denial of Service (DDoS) attacks are threats that website owners must familiarize themselves with as they are a critical piece of the security landscape. Navigating the various types of DDoS attacks can be challenging and time consuming. To help you understand what a DDoS attack is and how to prevent it, we have written the following guidelines.

What is a DDoS attack?

1.1 – Understanding a DDoS Attack

The objective of a DDoS attack is to prevent legitimate users from accessing your website. For a DDoS attack to be successful, the attacker needs to send more requests than the victim server can handle. Another way successful attacks occur is when the attacker sends bogus requests.

1.2 – What is the Goal Behind a DDoS Attack?

The main goal of an attacker that is leveraging a Denial of Service (DoS) attack method is to disrupt a website availability:

The website can become slow to respond to legitimate requests.

The website can be disabled entirely, making it impossible for legitimate users to access it.
