When electrical power is disrupted or cut off, data and programs are lost in : Correct Answer RAM

RAM কে ভোলাটাইল মেমোরি বলা হয় কারণ এতে সংরক্ষিত তথ্য বিদ্যুত সংযোগ বিচ্ছিন্ন হওয়ার পর আর থাকে না। আরো কিছু নন - ভোলাটাইল মেমোরি (যেগুলোতে বিদ্যুত চলে যাওয়ার পরও তথ্য মুছে যায় না) যেগুলো রক্ষনাত্মক দৃষ্টিতে RAM সেগুলো হল রম, একধরনের ফ্লাশ মেমোরি যাকে নর - ফ্লাশ বলে। প্রথম RAM মডিউল বাজারে আসে যেটা তৈরী হয়েছিল ১৯৫১ সালে এবং ১৯৬০ দশকে এবং ১৯৭০ দশকের প্রথমদিকে বিক্রি হয়েছিল।

Last year, there were three sections in a competitive exam. Out of them 33 students cleared the cut-off in Section A, 34 students cleared the cut-off in Section B and 32 students cleared the cut-off in Section C. 10 students cleared the cut-off in section A and section B, 9 cleared the cut-off in section B and section C and 8 cleared the cut-off in section A and section C. The number of students who cleared only one section was equal and was 21 for each section. How many students cleared all the three sections?
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.
In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. It is widely known that the use of social media affects mental health, but a new, three-year study has found that it is the lack of sleep from its use and the psychological distress caused by cyberbullying via the platforms that are the main reasons affecting one’s state of mind, more than use of the actual apps. P. Girls who were checking social media also reported to be less happy and more anxious; however, boys didn’t report the same feelings. Q. In girls, the researchers said, the negative effects were due to disrupted sleep, cyberbullying and to some extent, lack of exercise. R. Researchers found that girls and boys who checked social media sites more than thrice a day had poorer mental health and greater psychological distress. S. In boys, the same three factors — disrupted sleep, cyberbullying, lack of exercise — had an effect too, but it was much smaller. 6. Dr Dasha Nicholls, from Imperial College London, who was also involved in the study added, “It’s not the amount of social media, per se, it’s when it displaces real-life contact and activities. It’s about getting a balance.”

Directions : In each of the following questions a statement is given, followed by three conclusions. Give answer :

Statement : In spite of the heavy rains the traffic has not been disrupted this year.

Assumptions :
I. The traffic is disrupted in rainy seasons only.
II. Rains do not affect traffic movement.
III. Adequate precautions were taken for traffic management during rainy season.
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.

Below stated are some of the statements about the Alternating current. You need to identify which of the following is incorrect, 1. DC power is far more powerful than AC power. The efficiency and power to size characteristics of DC motors and apparatuses are increased. Lighting by DC (LED) is 75% more efficient than lighting from incandescence. 2. A comparatively high voltage alternating current may be generated and easily raised and dropped by the static equipment known as the transformer, which makes electrical energy transmission and distribution economical, 3. Initial costs and maintenance of the AC motor are less expensive since it has no switch and is less powerful than the DC motor for constant working speed, hence it is desired to create power as alternating current. 4. The great efficiency of transmission in ac makes electric power generation cost-effective, Produced in huge quantities in one station and distributed throughout a vast area.
