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.

if ((x%3) == 0) {
s = "Divisible by 3";
} else {
s = "Not divisible by 3";
}
System.out.println(s);
Explanation:
A : B ? C generally translates to if (A) { B } else { C }.
Note the == to compare to 0. The single = in the original expression is a mistake.
ou need to implement a wireless network link between two buildings on a college campus. A wired network has already been implemented within each building. The buildings are 100 meters apart. Which type of wireless antenna should you use on each side of the link
Answer:
High-gain and directional wireless antenna.
Explanation:
WiFi can be defined as a wireless local area network that allows network devices such as access points (APs), computers (both laptops and desktops), smartphones, smart televisions, etc., to communicate with each other wirelessly over a short-ranged network. It is a standard communication network that uses radio waves to establish a channel (medium) between multiple network devices.
This ultimately implies that, the network range or distance covered by WiFi is largely dependent on transmission power and frequency. Generally, the standard range or distance covered by WiFi is about 50 meters (160 feet).
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver through the use of an antenna.
In this scenario, you need to implement a wireless network link between two buildings on a college campus, which are 100 meters apart.
A high-gain antenna is an electromagnetic device that typically has a gain rating of 12dBi or sometimes higher. Also, a highly directional antenna can only receive radio signals from a specific direction and it compresses the radio waves that are being transmitted from a sender in to a very narrow beam.
Hence, the two (2) type of wireless antenna you should use on each side of the link are a high-gain antenna and a directional wireless antenna.

The attacker sent data that was able to manipulate the return address that is reserved to store expected data
Complete Question:
An attacker gained remote access to a user's computer by exploiting a vulnerability in a piece of software on the device. The attacker sent data that was able to manipulate the return address that is reserved to store expected data. Which vulnerability exploit resulted from the attacker's actions?
Answer:
A buffer overflow.
Explanation:
In Computer science, a buffer can be defined as a temporary area set aside for data storage. Buffers reside in the random access memory (RAM).
In the event that, a system process or program places more data (much more than what was originally or initially intended to be allocated for data storage) in a buffer, the extra data overflows. Consequently, this would result in having some of the data to flow into other buffers and thus, causing the data to be overwritten or corruption of the data being held in that buffer.
For example, we can liken a buffer-overflow to pouring water (data) into a container (program memory), once it is filled the water begins to overflow as the container has reached its maximum amount.
In this scenario, the vulnerability exploit which resulted from the attacker's actions by manipulating the return address that is reserved to store an expected amount of data is referred to as a buffer overflow.
Assume there are two variables, k and m, each already assigned a positive integer value and further assume that k's value is smaller than m's. Write the code necessary to compute the number of pertect squares between k and m. (A perfect square is an integer like 9, 16, 25, 36 that is equal to the square ot another integer (in this case 393, 4*4, 5*5, 6*6 respectively). Assign the number you compute to the variable q. For example, if k and m nad the values 10 and 40 respectively, you would assign 3 to q because between 10 and 40 there are these perfect squares: 16, 25, and 36.
Answer:
Lets us take k, m = 10, 40
q = 0
i = k
while i <= m:
if int(i*0.5)*2 == i:
q += 1
i += 1
what allows an individual or company to share a post with an audience however they are designed to be used with mobile devices and limit the size of posts
Answer:
Explanation:
The sending of messages via the Internet is known as e-mail. It is one of the most often utilised functionalities for sending text, files, pictures, and other attachments across a communications network.
A podcast lets a person or corporation to share articles with an audience, but it is geared for usage on mobile devices and has a capacity restriction.
It is the way to convey a message,an idea,a picture,or speech that is received and understood clearly and correctly by the person for whom it is sent.
Answer:
Communication.
Explanation:
Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.
In this context, communication is the way to convey a message, an idea, a picture, or speech that is received and understood clearly and correctly by the person for whom it is sent.
Generally, the linear model of communication comprises of four (4) main components and these are;
1. Sender (S): this is typically the source of information (message) or the originator of a message that is being sent to a receiver. Thus, they are simply the producer of a message.
2. Channel (C): this is the medium used by the sender for the dissemination or transmission of the message to the recipient. For example, telephone, television, radio, newspapers, billboards etc.
3. Message (M): this is the information or data that is being sent to a recipient by a sender. It could be in the form of a video, audio, text message etc.
4. Receiver (R): this is typically the destination of information (message) or the recipient of a message that is being sent from a sender.
An attacker gained remote access to a user's computer by exploiting a vulnerability in a piece of software on the device. The attacker sent data that was able to manipulate the return address that is reserved to store expected data. Which vulnerability exploit resulted from the attacker's actions
"A Buffer overflow" vulnerability exploit resulted from the attacker's actions.
Whenever a software or an application writes too much data into a buffer, causing neighboring storage regions to have been corrupted as a consequence, this could be determined as Buffer overflow.
⇒ There are two kinds of Buffer overflow attacks such as:
Stack-based - It will become more popular to use such memory, as well as that's only available during implementation of any code.Heap-based - Those attacks seem to be more difficult to execute because they entail overflowing overall storage capacity allotted for a program further than the space needed for something like the program's present activities.Thus we can say that the correct answer is a Buffer overflow.

Don's company has contracted with a service provider to receive a computing platform for all employees, complete with an operating system, database services, and a Web server. Don develops applications using tools delivered by the service provider. What type of service has Don's company signed up for?
Answer:
Platform as a Service (PaaS).
Explanation:
Cloud computing can be defined as a form of data computing which requires the use of shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Basically, cloud computing comprises three (3) service models and these include;
1. Platform as a Service (PaaS).
2. Software as a Service (SaaS).
3. Infrastructure as a Service (IaaS).
Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.
The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.
Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).
Hence, the advantage of the Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.
These are the different types of Platform as a Service;
1. Private PaaS.
2. Public PaaS.
3. Open PaaS.
4. Mobile PaaS.
5. Communications PaaS.
6. Hybrid PaaS.
In this scenario, the type of service Don's company signed up for is called Platform as a Service (PaaS).
