Statement (I): M-ary PSK can be used to transit digital data over a non-linear bandpass channel, whereas M-ary QAM requires the use of a linear channel. Statement (II): M-ary PSK and M-ary QAM are examples of non-linear modulation. Correct Answer <span style="">Statement (I) is true, but Statement (II) is false.</span>

M-ary QAM :

QAM is a linear method of digital modulation and requires the use of a linear channel. (statement 2 is incorrect)

PSK is a linear modulation and can be used to transmit digital data over a non-linear channel.

Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. We live in digital times. The digital is not just something we use strategically and specifically to do a few tasks. Our very perception of who we are, how we connect to the world around us, and the ways in which we define our domains of life, labour and language are hugely structured by the digital technologies. The digital is everywhere and, like air, invisible. We live within digital systems, we live with intimate gadgets, we interact through digital media, and the very presence and imagination of the digital has dramatically restructured our lives. The digital, far from being a tool, is a condition and context that defines the shapes and boundaries of our understanding of the self, the society, and the structure of governance. Which among the following is the most logical and essential message conveyed by the above passage?
The question given below consists of a statement, followed by three arguments numbered I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments and which is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: In an interview with ETCIO.COM, Kuruvilla Markose, Chief Digital Officer of Titan shares his perspective on how technology is serving the company’s digital vision and the various initiatives that he is spearheading to hone the competitive edge of Titan. He is the first CDO to be appointed by the software conglomerate Tata Group. He is the man who has put the Titan’s digital transformation on fast-track. Which of the following arguments support the fact that Kuruvilla Markose has put Titan’s digital transformation on fast-track? Arguments: I. Markose is a man with a vision. He is the first CDO to be appointed by the software conglomerate Tata Group. He has spent his entire two decade long career in Tata Group. He has been in customer facing roles across different group companies.  II. His CDO role is horizontal and supports Titan’s myriad business lines: watches, jewellery, bags, perfumes wallets, and eye-wear. But the man and his words are grounded. Diny, as he is popularly known, is a man of measured speech and bearing. III. “Digital innovation”, according to Markose, is all about creating value for the customer. To him, customer centricity is the road to longevity in the digital age. Under his stewardship, Titan has launched a panoply of digital initiatives aimed at improving customer centricity.

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.
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.

Consider the following statements regarding modulation : 1. The communication systems, where a weak signal is transmitted by the use of a modulation is essential in carrier signal. 2. When the frequency of the high frequency signal is varied in accordance with the intensity of the low-frequency weak signal, the modulation is said to be frequency modulation. 3. The process of recovering original baseband signal from the modulated signal is called phase modulation. Which of the above statements are correct ?
