Transmission data rate is decided by ____________

Transmission data rate is decided by ____________ Correct Answer physical layer

Physical layer is a layer 1 device which deals with network cables or the standards in use like connectors, pins, electric current used etc. Basically the transmission speed is determined by the cables and connectors used. Hence it is physical layer that determines the transmission speed in network. Some of the cables used for high speed data transmission are optical fiber cables and twisted pair cables.

Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.

If the transmission co-efficient T₁ of a transmission line is 1.333 and the characteristic impedance of the λ/4 transmission line used is 100Ω, then the characteristic impedance of the transmission line is:
Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Read the statements and choose the correct answer:
Assertion (A) The nominal interest rate comprises of a real interest rate and an expected rate of inflation and it adjusts when the inflation rate is expected to change. Hence, in the perfect international capital markets, real rate of returns are equal in the two countries.
Reason (R) The international fisher effects states that the nominal interest rate differential must be equal to the expected inflation rate differential In the two countries.
Consider the following statements regarding Time-Division Multiplexing (TDM): 1. The information from different measuring points is transmitted serially on the same communication channel. 2. It involves the transmission of data samples rather than continuous data transmission. 3. It is especially useful when telemetering fast-changing, high bandwidth data. Which of the above statements are valid in respect to TDM?
A 29-year-old primigravida comes to the obstetrician for a prenatal visit. She is known to be HIV positive. She also has asthma, for which she uses an inhaler. She has no known drug allergies Extensive counselling is given to her regarding vertical transmission of HIV to her baby. It is recommended to her that she take antiretroviral therapy during the pregnancy to decrease the vertical transmission rate. It is also recommended to her that she have a scheduled Cesarean delivery. After consideration of these options, the patient chooses not to take the antiretroviral therapy and opts for a vaginal delivery. Which of the following represents the approximate risk of vertical transmission for this woman:
In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the suggested course of action logically follow (s) for pursuing. Statement: The India Risk Survey 2017 report ranks 'Information & Cyber Insecurity' as the biggest risk facing Indian companies. Indian organizations, both public and private, had witnessed over 27,000 incidents of security threat, from January 2017 till June 2017 alone. Phishing, scanning/probing, website intrusions and defacements, virus/malicious code, ransomware, Denial of Service attacks, and data breaches are some ways in which hackers attack business websites, which can cause operational disruptions and potentially steal sensitive information. Small and medium businesses (SMBs), unfortunately, have been seeing rising incidences of cybercrime. In fact, 70 percent of cyberattacks occur at organizations with lesser than 100 employees  Courses of action: I. Mandate basic security practices and policies for all employees, such as 2-factor authentication, internet use guidelines and create and enforce rules on handling and protecting sensitive data. Conduct frequent training to sensitize employees about opening suspicious emails, encrypting their data, using strong passwords on their devices, installing security apps, and limiting activity over public Wi-Fi. Implement and enforce incident reporting to help ensure that even the smallest breach is report to management as well as the IT teams. II. Basics still matter and are some of the best defenses against viruses, malware, and other online threats. Assess the assets that are most at risk - data, servers, network - and ensure that the systems are updated with the latest security software, web browser, and operating system. Implement firewall security and run antivirus software after each update.  III. Ensure regular backup of all critical data - whether stored in-house or on the cloud. Run scheduled attack drills and stress tests to identify vulnerabilities and ensure that data restoration and business continuity are executed as planned.
Given below are six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four-sentence in each have been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences. S1: The dawn of the information age opened up great opportunities for the beneficial use of data. P: But it is the conflict between the massive scope for progress provided by the digital era and the fear of loss of individual autonomy that is foregrounded in any debates about data protection laws. Q: It also enhanced the perils of unregulated and arbitrary use of personal data. R: It is against this backdrop that the White Paper made public to elicit views from the public on the shape and substance of a comprehensive data protection law assumes significance. S: Unauthorised leaks, hacking and other cyber crimes have rendered databases vulnerable. S6: To some, in this era of Big Data analytics and automated, algorithm-based processing of zettabytes of information, the fear that their personal data may be unprotected may conjure up visions of a dystopian world in which individual liberties are compromised.
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create anapplication. The application uses the ADO.NET Entity Framework to model entities. Theapplication allows users to make changes to entities while disconnected from the central data store. You need to ensure that when the user connects to the central data store and retrieves new data, the application meets the following requirements:
  • Changes made to the local data store in disconnected mode are preserved.
  • Entities that have already been loaded into the local data store, but have not been modified by the user, are updated with the latest data.
