Application Presentation Session | Data | Transport | Segment | Network | Packet | Data Link | Frame | Physical | Bit | 3.2.3 Briefly explain the deencapsulation steps in the communication from host B receiving a message from host A destined for an active application. First the receiving computer synchronizes with the digital signal by reading binary numbers. After synchronizing is complete and it gets the whole frame and passes it to the layer above it which is the Data Link layer. Second the Data Link layer will do a Cyclic Redundancy Check (CRC) on the frame. Checking for errors and then strip off any information or header which was put on by the remote systems Data Link layer and pass the rest to the Network layer. Third the Network layer checks the IP address and if it matches the Network layer header is stripped off from the packet and passed to the Transport layer. Fourth the Transport layer processes the segment and...

...Alyssa Bauman En1320 Lab3 “Why We Crave Horror Movies” by Steven King presents an intriguing philosophy of watching horror movies. I believe that the purpose behind this article is to appeal to the reader’s unrealized dark side. King implies that are able to overcome their hysterical fear of things when they’re confronted with it and watching a horror movie is the easiest way to do that. He explains that in some way we all have this courage to overcome our deepest fears and one of the ways we show it is placing ourselves, in this case a movie theater, directly in front of what we know will scare us. The intended audience for this article is most likely the younger age demographic. Horror Movies are especially popular with ages 15-35. When you are younger you have this need to seek out new experience and thrills. Throughout the essay King directs a message to the young by making a comparison of horror movies to roller coasters describing the excitement that is felt throughout the ride. King is trying to persuade his reading audience to watch horror movies that bring his popularity up because he has books that have been made into movies. Although persuasive, King's article does not have factual evidence to solidify his argument that we all crave horror movies. The article uses many rhetorical strategies such as: compare and contrast, analysis and evaluation, cause and effect, absolutes, generalizations, and assumptions. King's ability to use these strategies demonstrates...

...Worksheet for Interactive Lab3: Circular Motion Name _____________ Physics 216 Grade ___/42 Date ______ Circular motion is one of the fundamental building blocks for understanding the physical world because it is so common. This interactive lets you examine the basic ideas of kinematics and forces for objects moving in circular motion. 1. (6 points) Use the controls under Show Vectors to draw arrows for several different quantities. The velocity vector is drawn in a special way: a big, bold arrow showing its direction and magnitude, plus smaller arrows for its horizontal and vertical components. * How are the directions of the acceleration and force vectors related? Force has a magnitude and a direction, and it is a vector. If a force is applied to an object, the object will accelerate in proportion to the magnitude of the force and in the direction of the applied force * What about the directions of the velocity and force vectors? The velocity of the object changes in response to the application of force. * And how are they influenced by the increase in mass and velocity slide bars? This question can be answered by the equation F = ma or force equals the product of mass and acceleration. An increase in mass or acceleration will result in more force. 2. (6 points) The large slider on the left changes the angle at which you view the spinning system. Try watching the motion from above (the default) and from the side. What would the system look like...

For a uniform absorbing medium (solution: solvent and solute molecules that absorb light) the proportion of light radiation passing through it is called the transmittance, T, and the proportion of light absorbed by molecules in the medium is absorbance, Abs. Transmittance is defined as: T = I/Io where: Io= intensity of the incident radiation entering the medium. I = intensity of the transmitted radiation leaving the medium. T is usually expressed as percent transmittance, %T: %T = I/Io x 100 The relationship between percent transmittance (%T) and absorbance (A) is given by the following equation: A = 2-log (%T) On most spectrophotometers two scales are present, %T and Abs. Absorbance has no units (Why?) and varies from 0 to 2 (linear region for most substances is from 0.05 to 0.7). The Beer-Lambert Law states that Abs is proportional to the concentration (c) of the absorbing molecules, the length of light-path through the medium and the molar extinction coefficient: A = εcl where: ε = molar extinction coefficient for the absorbing material at wavelength in units of 1/(mol x cm) c = concentration...

...This is newest updated file from today. See below. IP Subnetting Project XUMUC is has the WAN links in place to the new locations in the Houston Region. XUMUC currently has 2 other Regions San Francisco and Denver. Originally, XUMUC was only in one region (San Francisco). The previous consultant did a poor job with the integration resulting in a poor IP address scheme as a result routing tables at the summarization points and at the San Francisco Campus are very large. In addition, no VLAN structure was developed to isolate broadcast traffic. There are 4 main departments in XUMC: sales, finance, human resources, and research and development. Also, there has been some concern that the WAN transport was not able to accommodate the network traffic. The XUMC sales team has added a call center with hours of operation from 9AM-9PM EST. Access to the call center network should be restricted after hours. The research and development department has (3) unique special projects which will require over 1000 devices to be enabled to use IPV6. A new network should be created for this area. Finally, all addresses in the network are statically assigned resulting in high administration overhead when changes are needed XUMC would like this changed to lower administrative overhead. The Board of Director meet and decided to add a Security Analyst role to the team. The new Security Analyst has request the access restrictions be documented. The Finance Department should have restrictions...

...Active Directory structure and Domain Controller configuration: DHCP We will be using DHCP for wireless devices. All other devices (servers, printers, lab PCs, switches) will receive static IPs as they will all be permanent fixtures. I have DHCP enabled on both DC’s with a split-scope configured for the wireless address pool. This will help with load-balancing and will ensure that if DC1 goes down, wireless devices will still be able to receive an IP address from DC2. Active Directory Users and Computers User Groups are located under the Users container. All users will be in the Domain Users group, and then will be added to Domain Admins, Server Admins, Faculty, or Students based on role. Guest users will be added to Domain Guests. User accounts are generated with first initial, last name, and a number to distinguish duplicates (e.g. Anthony Matthews becomes amatthews001) Domain Controllers will remain in the Domain Controllers OU, Servers will be in the Servers OU, and workstations will be under the workstations OU in the OU that corresponds to their physical location (i.e. lab 1-3) This will allow us to apply GPOs to all devices based on location and role. Domain Controllers are WestSideDC01 and WestSideDC02, Lab machines are named with Lab name and an assigned number (e.g. Lab1PC1) Group Policy Management Currently I have the following options configured with group policy: Server Admins – adds the Server Admins security group to the Administrators group...

...Point of sale evaluation case study Name Institution Course Date Task 1 Evaluation of POS system Evaluation of a POS system involves an analysis of its features and usability to the user needs and requirements. Evaluation of a POS system helps the user order for the most appropriate POS system for their retail operations. In skate board selling, an appropriate POS needs to fulfill several factors to ensure a smooth flow of transactions for both the administrators and users. From lab 3, criteria covered include the set up and configuration, data entry, customization and mail merge. These criteria have left out several important consideration factors for an appropriate POS for skate board selling. The evaluation has not fully considered important aspects of the POS especially its interaction with the environment (users, administrators and clients). One of the important criteria left out by lab 3 evaluation is the time required for implementation. The sellers of skate boards should be aware of how long the system is going to take to install and run. This should consider its integration with the current systems. The time should be valued in terms of cost, ranging from expenses of training the employees to cost implications that may happen upto the time the users understand the POS operations fully. This is important in that it gives the unseen cost for the retailers of the skate boards. Another left out evaluation criteria is system security. System security ranges...
