Answer:
The Random-Access Memory (RAM) should be upgraded.
Explanation:
Since the particuar apllication is taking alot of memory space it means that an ugrade/ installation of a bigger RAM would help the system work better while using the program
COMPLETE QUESTION
Which of the following is false?
a. A subclass is often larger than its super class.
b. A super class is object is a subclass object.
c. The class following the extends keyword in a class declaration is that direct super class of the class being declared.
d. Java uses interfaces to provide the benefits of multiple inheritance
Answer:
B) A super class is object is a subclass object.
Explanation:
In object oriented programming, the concept of inheritance is greatly utilized, this refers to deriving a class from another class. The derived class is the sub-class and it is derived from its super class, as a matter of fact in Java programming language, all classes are derived from some other class. Objects are made from classes with their state (fields) and behavior (methods) since objects are made from classes, the objects of the super class will not be the same as that of the subclass.

<em>Intrusion means unauthorized and harmful activities happening in your system. Any irregularities in the system is considered as intrusion and therefore monitored by administrators and can be detected using Intrusion Detection System.
</em>
<em>Examples of Intrusion attacks in a network are:
</em>
- <em>Denial of Service (Dos) - denial of service means flooding the system causing it to crash and unable to respond to a service request. Normally, a DoS attack is facilitated by numbers of hosts sending enormous request to a victim computer. The requests can be in a form of code that would flood the system and making it to unresponsive. </em>
- <em>Man in the Middle Attack (MiM) - a hacker would be in the middle of the communication between a client computer and a server computer. The hacker can mimic IPs within the network and steal information then sends it to the intended receiver. </em>
- <em>SQL Injection - For websites that runs database like SQL, a code by the hacker can be added to the website and making him gained access to the database information successfully.</em>
