...1.Describe the purpose of an RPC. A) Remote Procedure Call (RPC) provides a different pattern for accessing network services.It provides Instead of accessing remote services by sending and receiving messages, a client invokes services by making a local procedure call. The local procedure hides the details of the network communication. The main purpose of RPC is to hide the existence of the network from a program.RPC is especially well suited for client-server (e.g., query-response) interaction in which the flow of control alternates between the client and server. Conceptually, the client and server do not both execute at the same time. Instead, the thread of execution jumps from the caller to the callee and then back again. 2. When two computers request a connection, what are the four primary actions that the Session Layer takes? A)the two computers connecting through 7layers ,in this Layer 5, the session layer, allows two applications on different computers to open, use, and close a connection called a session. The session layer is responsible for managing this dialog. It performs name-recognition and other functions, such as security, that are needed to allow two applications to communicate over the network. It performs the following four primary actions The session layer synchronizes user tasks by placing checkpoints in the data stream. The checkpoints break the data into smaller groups for error detection. If the network fails, only the data after the last checkpoint...

... The first thing that Julie should do is have a staff meeting bring absolutely everyone in and make sure every employee is aware of the securities breaches that have been going around. For her to have a success meeting she must have an already created handout for each employee explaining to the front desk to provide as little information as possible over the phone, through email, or face to face with someone who has not shown identification. This is the first thing she should do because it is the most significant. If everyone is aware of the problem they could take precautions when giving sensitive information to the guest, licensees, and invitees. With everyone being aware of a security breach everyone will be on their guard and it would be hard for the hacker to get the sensitive information out of one the employees because regardless of how smart the computers are humans still control them. Following her reporting the issue to every single staff member she should start working on the technical issues. She should have everyone reset their password and time the computer out every time someone is away from it for 10 minutes or more. Second, she should make sure that the hotel's network cannot be accessed passed the driveway, that would narrow her suspects to only people who have entered the property. Third, she should monitor the front desk because they have the most sensitive information there should be alerts of declines, outrages fees, as well as fraud cards. She should...

...Question 2: The design portrayed in this example is a non-equivalent control group posttest-only design where each exam presented during the semester functions as a posttest measure. The teacher is utilizing one of the classes as a control group and one as the treatment group (for example, the weekly quiz group). The teacher is subsequently taking posttest measures by giving them exams. Since the participants were not randomly assigned to the two conditions and instead preferred the section of her class in which they enrolled, this is considered a quasi-experimental design. Question 4: There is no equivalent control group or random assignment. Question 6: A researcher may only desire data on the single participant being studied and, therefore, choose to employ single-case research. Secondly, single-case designs permit for simpler replication as only one additional participant is required rather than another group of participants (Jackson, 2012). Thirdly, group designs may influence error variance due to the rise in individual differences (Jackson, 2012). Consequently, single-case research would diminish error variance. Question 8:...

...I have received feedback from the end users and the information is easy to get the information that they are looking to research. There was some of the providers that stated, “My provider is not in the system with the information” (End User), I informed them that they would have to contact the third-party vendor to assist them is getting their provider set up in their system. The survey feedback from the testers were all received and reviewed and started to compile suggestions and changes that they would like to have added to the report. Some of the suggestion are as follows: • Medicaid Number • Medicare Number • Level of Service (LOS), (RUG) • Level of Service (LOS) rate • Monthly Applied Income • Electronic Fund Transfer or Check Number In reviewing their suggestions, it was time to go back to the IT department with the suggestions and refine the prototype with the suggestion and if it was possible that we could add the information to the report without any problems on the MCO’s end. The feedback from the management team and the IT department was to generate another prototype with the suggestions and arrange it in a way that the primary end users would like to see.

...A - Assigned tasks My position required me to focus on various tasks to support the team. However, on a daily basis, my assignments were not repetitive at all. A few tasks I did had to be done every months or quarters. Below is a list of the main requests I had to fulfil, from the most frequent to the least frequent. - The cornerstone of my internship was to manage an Excel database with more than 5000 lines and 700 columns. This database included all the historical and current information the team could ever need about all of our clients in the UK, Africa, Middle East, central Europe and eastern Europe. For instance, it included data such as the contract terms, the subscriber numbers, the revenue in the contract currency and US dollars for each client. I had to keep it updated to reflect the correct contract terms, the latest subscriber numbers and revenue figures, and add the new clients and remove the ones terminating their contracts. As well, it had to be restated to different monthly FX rates and clearly show our forecasts per month, quarter, and year. This database was frequently checked by my line manager. I used it as my raw data source to do any analysis required by senior people which is why it had to be accurate. It required a meticulous daily-work. - Once this database was up to date and reflecting our latest forecast, I was able to trust it and use to fulfil ad-hoc request coming from different teams such as marketing, research, legal, and strategy. The number...

...1. As a leader of this congregation, how would you take the Smiths’ suggestion? I would address the need to pray over the decision and ask that George come to the meeting to discuss if this would be some interest to him attending and why. I think having George actually say yes, I want to or no I don’t want to attend this meeting and why, in front of everyone would be helpful in gaining the non-smith family board members support for why Elizabeth should go. 2. What values are evidently apparent in the dynamics of this congregation? John Smith seems to value his family having control of the pastor and the church. He knows that his family is a majority of the congregation and without the majority of the congregation the church may struggle staying open financially or the pastor may be asked to leave. Manipulation seems to be a value also, because John Smith wants to be the person to make the suggestions and if a suggestion isn’t from him, he will kindly say that it will not work and that they have tried it before when the pastor may have no idea of what really happened before due to the high turnover. 3. How can you minister to the Smith family in a way that is meaningful to them and beneficial to the overall ministry of the church? Ministering to the Smith family solely through the Holy Spirit is essential. Not letting my flesh rise up to be in conflict with them would be the way for me. I often tell my friends that being a Christian always means being the bigger person...

... Basically, to solve those problems that mentioned above, an web application system that needs to be created which allow the users to manage their data and protect by encrypt and decrypt the related data of the patients. The proposed of the system is by having a technique which will allow to encrypt the data of the patient by using symmetric encryption and cryptographic hash md5. The symmetric is old and the best know the technique used it to secure the data and encrypt and decrypt the message by using a private key which can be a number, word, or just letters. The hash md5 is a kind of of security mechanism that produces a message digest, hash value or the checksum value for a specific data object. As mentioned above, symmetric encryption can be very helpfully solution by acting as a supplementation of encryption data. Using encryption is a good method to protect and secure sensitive data from any unauthorized users. Therefore a combination of encryption and cryptographic hash are better way to provide better security level and increase the defenses of secure data. Tangible Benefits: • Reduce workload of doctor and nurse by providing all information of the patients in the database system. Doctors and nurse do not have to write the data of their patients in manually work and then send to the department instead of that they can save it in system which will help them to access any time. • Enable to access the data of patient records in limited time with more coordinated, efficient...

Use the DBMS in Fig. P12.1 to determine the types of operations that would take place in the database for the following transactions: a. For this operation, there is only one statement present, and since it is only referencing one remote database. It will therefore only require the use of remote requests operations. b. For this operation, there again is only one statement present, and since it is only referencing one remote database. It will also only require the use of remote requests operations. c. For this operation, there is only one statement present, but since it is utilizing two different remote databases (one in Site A and one in Site C).

...Unit 7 I interviewed my grandparents for this unit’s assignment. My grandma Marcia is seventy four years of age, and my Papa Ralph is Seventy one years of age. I would consider them to be pretty hip with the times in regards to technology. I have volunteered at an assisted living unit in the past and it is amazing to see adults of the same age as my grandparents who either do not use internet, do not know how, or do not want to learn. My grandparents have always tried to keep up with the times and learn as much as possible. They have asked my cousins and I in the past to help them learn how to use certain technologies. I taught my grandma how to text and now that is one of her main forms of communicating. My cousin taught them how to set up everything on their computer and how to use their iPod. One of their favorite technologies is the iPad. The websites that they visit the most are the Harkins theatres website, the Walgreens app, and Facebook. It...

...This week’s lab dealt with the application of encryption and hashing algorithms to a test file on the Linux operating system. I chose this lab over the other lab option because I find this topic of particular interest and something that I can apply in my day to day duties at my current employer. I also enjoy working with the Linux operating system because I have always found it to be more challenging than Windows which I deal with daily. I had no trouble launching the virtual environment and accessing the Linux virtual machine. The lab used a text editing program called gedit which I am also familiar with and is similar to the notepad application sound withing Windows. The gedit application is launched by using the terminal window within the operating system which is a command line tool. All of the steps in the lab are completed by executing commands in a terminal window and I was able to perform them without any issues except for a couple minor typing errors. By entering commands into the terminal, the user is able to call other programs in the operating system and perform a variety of tasks. After the test file was created using the gedit command, I was able to create a hash using the md5sum command. This generated a unique string that can be used to verify the integrity of the file. After adding additional text to the same test file later in the lab, the hash value was regenerated and it was indeed different than the first generated hash. This has many benefits, but is commonly...

...Assignment Description: For the unit 2 assignment, I needed to develop a critical path method (CPM) for the design phase of the ABC Video Rental store project. It was suggested that we use table 6-6 from The New Software Engineering by Sue Conger (2008, p. 167) as a guideline for the development of the CPM. Table 6-6 outlines the functional requirements for the program and what different software options, existing or available for development of the application, would be able to meet those requirements. A table that I found more useful for the assignment goals was Table 6-16 which outlined and defined design phase tasks along with an estimated function point value for each task (Conger, 2008, p. 188). After displaying my CPM for the ABC project design phase I will outline the critical path, the various tasks that fit the dependencies from table 6-6, how the various tasks might be distributed between a two-person team of a project manager and software...

...methods to balance the volumes in groups, while in [3] a heuristic algorithm via relaxed convex approximation used to achieve both the minimum communication load and load balancing between groups. According to [3] the optimal solution for minimizing the communication load and achieving the best load balance among servers is considered NP-Hard, there is no polynomial time algorithm to find the optimal solution. The relaxation technique [4] transforms an NP-hard optimization problem into a related problem that is solvable in polynomial time. In [3] the algorithm splits a number of m servers into two equal numbers of servers in each group. Repeats this step until number of servers at each group is equal to 1. If we have 6 nodes then according to [3] there will be 6 combinations of two groups that will have to be checked to find the one that achieves the minimum average communication load and load balancing. Two disadvantages appear in [3] approach as the following: 1. For bigger number of users n and m servers, the number of combinations to be checked will increase; this means it will become much slower and time complexity will increase. 2. If there was for example 3 clients that communicate frequently with each other through two servers, this mean one of the clients will be assigned alone to one of the servers, which will make the inter-server communication increase. In [5] an algorithm based on Semidefinite programming was proposed to obtain the optimal client server assignment...
