    Answer to Q#1 A transponder is a wireless communications, monitoring, or control device that picks up and automatically responds to an incoming signal. Transponders are microwave repeaters located at intermediate points in a communications link, which are used to compensate for the signal attenuation along the route to extend the range of the link. They receive the very weak signals from a sender at one end of the link, amplify them, and re-transmit them at much higher power to the receiver at the other end of the link. The whole purpose of a communications satellite system is to place a transponder in position, to keep it there and to keep it powered up. Because of the very high launch costs, for satellite systems to be economically justified, the transponder should be able to carry high traffic volumes including television channels as well as dozens of multiplexed voice communications and other data links. It should also be small and light. Questions: Marks 10 Question # 1 Marks 10 An organization has its satellite-based network that it provides direct broadcast services. This organization comes across signal attenuation problem due to the long distance communication links, which results in the poor service. As a network engineer, what you will advise to that organization to compensate this attenuation? Answer to Q#1 A transponder is a wireless communications, monitoring, or control device that picks up and automatically responds to an incoming signal. Transponders are microwave repeaters located at intermediate points in a communications link, which are used to compensate for the signal attenuation along the route to extend the range of the link. They receive the very weak signals from a sender at one end of the link, amplify them, and re-transmit them at much higher power to the receiver at the other end of the link. The whole purpose of a communications satellite system is to place a transponder in position, to keep it there and to keep it powered up. Because of the very high launch costs, for satellite systems to be economically justified, the transponder should be able to carry high traffic volumes including television channels as well as dozens of multiplexed voice communications and other data links. It should also be small and light. Answer to Q#2 Being a networking engineer, he should suggest the use of polynomial codes to the organization for desired objective. The benefits of using polynomial codes is that it produces short codes. For example, here a 6-bit pattern is replaced by 3 terms. In polynomial codes, the degree is 1 less than the number of bits in the binary pattern. The degree of polynomial is the highest power in polynomial. For example as shown in fig degree of polynomial x5 +x2 + 1 are 5. The bit pattern in this case is 6. A pattern of Os and 1s can be represented as a polynomial with coefficient of o and 1. Here, the power of each term shows the position of the bit and the coefficient shows the values of the bit. For example, if binary pattern is 100101, its corresponding polynomial representation is x5 + x2 + 1. Figure shows the polynomial where all the terms with zero coefficient are removed and x J is replaced by x and XO by 1. [image: PaLVAQh.png] [image: g2sLIBZ.png]

Now a days, SQLite use is increasing in embedded systems due to its advantages. SQLite will be more widely used in the embedded field, such as the remote control, intelligent mobile terminal, information appliances control, home medical equipment, mobile devices etc. In a multiplatform architecture SQLite having wide scope. Q. 2 Solution: Embedded devices or applications Replacement for ad hoc disk files Stand-in for an enterprise database during testing or demos Multi-user applications Data analysis Application file format Server-side database Data transfer format Cache for enterprise data Internal or temporary database Websites File archive/ data container Education and Training Experimental SQL language extensions

    • CIA triad Question No. 1 [Marks: 10] Suppose you are attempting the exam for the post of Information Security Engineer in the ABC organization. During the exam, you are given the following real life scenarios associated with the three main pillars of informing security (C.I.A) : Suppose fifty cancer patient’s treatment is being carried out by Dr. Ali in the well-reputed cancer hospital in Lahore. All the medical information of those patients is stored in the table of the hospital’s database system. Dr. Ali suggests medicine to the patients on the basis of patient’s relevant information stored in the database. If another doctor who has also legal rights to access this table of the database, unintentionally changes the information that can mislead the patient treatment. CSS Exam’s applicants are checking their results online through the FPSC website but the FPSC website takes too much time to load. The AZB limited Bank makes a plan for launching a new offer for capturing customers in a market but this plan leaked to its competitors. A bank’s ATM is not responding due to general backend server error. If a renowned shoe brand’s prices and specifications available on online shopping stores are changed by an unauthorized person. If you are replying to the messages of your friend, then it should be received in the original form as it is sent by you. Upon the last date of applying for the online job application, the related website is not responding due to some technical problems which makes the candidates unable to submit their job application on time. Student’s board results information (Marks, CGPA) is considered very important and it should be available only for that specific student and their parents rather than other class students. A developer’s salary slip in the software house should not be visible to any other developer. Student’s semester grades are posted on the class Facebook group by some unauthorized student. After carefully reading and analyzing the above-mentioned scenarios and fill the following table: Scenario. No Associated C.I.A security component 1 2 3 4 5 6 7 8 9 10 kindly i want solution of this question plzzz
