Question 2: determine the DWI components needed to complete the DWV system for the bathroom shown in figures below. The horizontal waste piping is 2 feet below the
and the second path is where ten is added to the value of the entrance and then the subtraction occurs. On the side you can see a series of logic gates that generate a function that will produce an output of 1 only when digit 1 of the exit is bigger than that of the entrance. This output will be sent to two different multiplexers, one for each digit. In the digit 1 diagram it will be sent to a multiplexer that will decide whether to use the subtraction where the entrance has been increased by 10 or whether to use the other where the entrance has had no alteration. If it is a 1, then it will use the first option where ten was added to the entrance. If it is a zero, then the latter will be used. This can be seen below in figure 2.
ANS 5: WTLS, it works with two sorts of figure frameworks they are block and stream ciphers . The Integrity can't be acquired by MAC address and these figures utilizing XOR where the tally of assets are less. On the off chance that a gatecrasher rearranges one piece then every square of figure with n bits parallel way MAC compares with reversal with the same n bits brings about n modulus 40. This makes the procedure to be rerun number of times .From the above expressed reason we can say that XOR MAC does not give respectability certification utilizing stream ciphers.
The accompanying directions were formed for introducing Sun Java 1.5.0_08 (otherwise known as JDK 5.0 refresh 8). This may not be the most recent variant, but rather the one we are utilizing this semester. Note: Java is as of now introduced as a feature of Mac OS X, so no further establishment is essential for these machines. Guarantee, however, that you have the correct form by writing java - rendition to the unix order provoke; the reaction ought to be something like java adaptation "1.5.0_08" A run of the mill Java establishment takes around 400 megabytes of circle space. The establishment procedure reports the correct size.
Wireless Routers is a wireless local area network (WLAN) that determine the next route of the packet should travel to the destination (Rouse, 2005). It converts the internet connection that was received from phone lines into radio signals and brings convenience to the portability devices that has built-in network card to gain the radio signals to get to the Internet connection (Switcher, 2015). Table 2 refers to the comparison of three models of wireless router.
Thank you again for your time to review our services and discuss your current HR technology needs. We look forward to working with you to find a provider for Carter Haston.
Assignment 7. Go online and search for information about security threats posed by browser add-ins, such as Java applets and ActiveX controls. Note that most of these programs are small in size and downloaded onto computers over the Internet. Look for a specific example of a security problem resulting from such add-ins, and document the problem in a case study.

One of the first things that Ms. Anderson should do is to change the classroom layout and environment for Howard. First, he should have particular seating by Ms. Anderson which is near the whiteboard, but far away from high movement areas, for instance, entryways, pencil sharpeners, or windows. She should create an area where she can provide individual instruction for Howard. Especially, surround Howard with peers who are helpful and not confrontation. He needs a defined space where he can work on class work. Having Howard follow a checklist throughout the school day will help him stay organize with class work, more focus on instruction time, and less distracted with any classmates.
Social media is one of the major lines of communication with people due to the advances in techlogly. Social media is the means of communicating from business to personal socializing. Social media can be effective for companies to communicate with stakeholders along with marketing. Marketing thru social media has already been a successful trend among companies, communicating with stakeholders could be more successful with the advances technology . People are glued to their cell phones , tablets and watches through out the day it will become easier and more effective if a stakeholders can communicating with the company anytime and immediate versus having to wait until they reach a computer and check email or company’s blog for updates. How convient is for a stakeholder to log onto Facebook, Twitter, Google , Instagram , Pinterest, and Tumble to see updates from their company and personal friends.Of course companies would’nt intevine on the personal /private interaction the stakeholders hold on these social media sites they will stick to company polices and relations.
Connectionless mechanism is similar to datagram mechanism of packet switching networks. Each data packets, individually, are routed from source to destination through a various routers and networks. At every router the next route is decided individually for the packets. Thus each data packets may travel different routes while travelling from source to destination. They share a common protocol called the Internet protocol (IP). IP is published in RFC 791, which has become an internet standard. Under this protocol, we need a protocol, which can be helpful to access a specific network.
D-ITG is used for generating traffic in the network. Random hosts and clients are selected for sending traffic. To get sufficient delay in the network the link is used up to 100% in case of heavy traffic, around 70% for medium traffic and 20% for low traffic. The receiver logs are registered for each flow. Flows nature is UDP as UDP does not re-attempt to send a dropped packet. The packet size is fixed to 1024 and number of packets send per second can be changed depending on the traffic requirement.
This section has represents the over read of connected paper support the present analysis. These papers do not seem to be utterly associated with project approach however positively enhance the performance of network routing protocol.
