WPA2 –Wi-Fi protected access version 2
This security was made because of the 802.11i wireless security standard. WPA2 is very similar to WPA but it uses AES – advanced encryption standard to encrypt. AES has a 128 bit key whereas DES – data encryption standard which was used before AES has a 64bit key. 64bit keys take a lot less time to break than 128bit key. The wireless AES key will be encrypted into 128 bits so a larger sequence of numbers which would need to be decrypted in order to access the key whereas DES which uses 64 bit encryption so half the size encryption as AES that is why AES is more secure.

Interconnection devices
1.interconnection devices allow connection between devices examples of these are such as router, switch, wireless access points.
2.A wireless repeater resends a signal when it is received to increase the wireless signals reach.
3.A hub receives data and transmits it to all connected PCs but a switch stores the mac address for all connected pcs so will only transmit to specific PCs not all that are connected.
4.a network bridge connects two or more networks together and is similar to a switch because it sends the correct information to each connected pc .it can be hardware or software.
5. A wireless access point (WAP) allows devices with wireless capabilities to connect to a network without the need for any cables such as Ethernet.
7. DTE short for Data Terminal Equipment, a device that controls data traveling to or from a computer.
8. In network computing, DCE (Distributed Computing Environment) is a software that is set up to manage data which is going into and out of
1. Planning Before you want to jump right into planning, you want to meet with your client to talk about the project, you want to obtain certain information so that it can help you learn more about the project and whether or not the project should go ahead. Once you accept doing this project, you want to make sure that the client knows the requirements you’re looking for and whether they will meet your standard. For example, your payment estimates for future stages of the project.
3.3. Frontier molecular orbital The electronic structure of the doped fullerene interacting with glycine compared to pure fullerene C20 has been calculated with density functional theory using the B3LYP/6-31G basis set. The molecular orbital theory, the relative chemical reactivity of a molecular system can be estimated using HOMO and LUMO energies and overlaps of molecular orbital [18-20]. The electronic transition from the HOMO to LUMO are mainly derived from the electron density transfer n orbital to p* orbital.
Our protocol takes two integers decomposed into encrypted bit vectors [a][b] and outputs the greater integer. In this configuration cloud 1 (C1) has the encrypted bit vectors of the integers being compared and cloud 2 (C2) knows the private key. The protocol is as follows in a very concise form. we can say with firm conviction that vector [Y] consist of encrypted zeros at every location except one location which holds the value of encrypted one. This distinct location identifies the first position where vector [a] and [b] differ.
1.2 RESEARCH OBJECTIVES: 1.2.1 Creating Data Set The images used in this work have been obtained from the Street View service developed by Google. It provides high- resolution views from various positions along many streets and roads in the world. These images are taken at discrete geographical locations defined by a pair (LAT, LON) (latitude and longitude in decimal degrees, respectively) [19].
NOT function is a logical function in Excel. It returns the opposite value of a given logical value in the formula. This function helps to check that one value is equal to another value or not. If we put TRUE in this function it returns False, it we put False then it returns True. We can use either TRUE or FLASE value in this function at a time.
Consider a fog network consisting of a pool of E cloudlets, some are active and some not, and a set u of N users that are distributed uniformly over the network area. Moreover, user-nodes (UNs)are interested in a set of A tasks, each task has required CPU cycles of k per bit of task data. In the proposed model we focus on the uplink transmission . UNs have computing tasks that arrive following Poisson
et us assume that $A_{ij}$ is the power received (expressed in dBm)by the frequency band $F_{i}$ at the time $T_{j}$. We have represented the data collected during our spectrum measurement by using a N $ imes$ M matrix designed by L. The matrix L is defined as: %%%%%%%%%%%%%%%%%%%%%%%%%% [ L = [A(F_i,T_j)]= egin{bmatrix}
\section{Building Blocks} \subsection{Access Structures} \textbf{Definition 3.8.}(Access Structure\citeup{beimel1996secure}) \emph{Let $\{P_1, P_2,...,P_n\}$ be a set of parties. A collection $\mathbb{A}\subseteq 2^{\{P_1,P_2,...,P_n\}}$ is monotone if $B\in\mathbb{A}$ and $B\subseteq C$ implies $C\in\mathbb{A}$. An access structure is a monotone collection $\mathbb{A}$ of non-empty subsets of $\{P_1,P_2,...,P_n\}$, i.e., $\mathbb{A}\subseteq 2^{\{P_1,P_2,...,P_n\}} \setminus\{\emptyset\}$. The sets in $\mathbb{A}$ are called the authorized sets, and the sets not in $\mathbb{A}$ are called the unauthorized sets}. In our settings, attributes will play the role of the parties such that the access structure $\mathbb{A}$ will contain the authorized

• Giving an orderly review of the current procedures for IDS, and the way in which these have been connected to IoT. • Exploring the future difficulties for IoT and the part that IDS can play. • Outlining the key zones where future research can enhance the utilization of IDS in IoT. Whatever is left of the paper is dealt with as takes after, Section 2 demonstrates the related works that have proposed the outline and overview about IDSs.
Full-duplex technology delivers up to 200 Mbps bandwidth; bi-directional communication, meaning that the 100 Mbps is available for transmission in each direction. Likewise, Full duplex also increases the maximum distance supported for fiber cables between two data terminal equipment (DTE) devices for up to 2 km. The IEEE 802.3z standard describes three types of transmission; 1000BaseSX over multimode fiber optic cable, 1000BaseLX over single-mode fiber
The difference between the two and three-tier client/server configuration, are the tiers (layers) that make up the systems. In a two-tier system you have a client and a server, each has the capability of doing the processing for the application (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012). The software is loaded on the client computer, and access the data server directly. In a three-tier system, there is an additional server/computer between the client and data server; this third component contains the business logic or processing for the application (Brown, DeHayes, Hoffer, Martin, & Perkins, 2012; Luke, n.d.). A three-tier configuration could be a web-enabled business application.
I clicked “New” and began. Immediately, a blank page appeared and was ready for me type in. I started working on a project for my C++ programming class. The instructions of the project seemed simple; I had to create an interface for a vending machine. To some people, this sounds difficult, but to me, its a problem waiting to be solved.
1 What type of documentation did you see and inspire you? To my perspective, all those projects have been a trip toward the unconscious mind of the child and has released his/her deep emotional and visual experience. Also, the project has been a bridge between the self-unconscious (intangible) and language of self-expression (touchable) as “Artifacts”. To me as an educator with major study field in graphic and Fabric design, the outcome of the documentation has been a pure art which was occurred based on the unconscious of the child and affected his/her behavior and emotions. For the art, the timing of skill and the skill itself must be primarily unconscious responses.
