Which of the following shell(s) allows the user to run jobs in the background even when the user has logged out (without using nohup command)? Correct Answer

Background jobs are terminated automatically when the user logs out. But in C shell and bash shell jobs are not terminated even after the user logs out. While this is not the case with Bourne and Korn shells. In these shells, jobs are aborted as soon as the user logs out.

Study the following information and select appropriate logical conclusion based on it. The Consumer Pyramids Household Survey quantifies the sharp fall in the rate of growth of jobs for the better educated in recent years. Over the last three years - between early 2016 and late 2018 -38 million jobs were added for people who completed only primary education, that is up to 5th standard. This implied that jobs for these barely educated people increased by nearly 45% over these three years. In comparison, people who had acquired a little better education that is between 6th and 9th standard, saw an addition of much lesser 18 million jobs implying also a lower 26% increase in jobs for these people. People who had completed secondary-to-higher secondary school education - 10th, 11th or 12th - saw a growth of 13 million jobs reflecting only a 12% growth over a three years period.
Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. Productive jobs are vital for growth and a good job is the best form of inclusion.

While industry is creating jobs, too many such jobs are low-productivity non-contractual jobs in the unorganized sector, offering low income, little protection, and no benefits. Service jobs are relatively of high productivity, but employment growth in services has been slow in recent years.

Statement: For users, Facebook's revelation of a data breach that gave attackers access to 50 million accounts raises an important question: What happens next? For the owners of the affected accounts, and of another 40 million that Facebook considered at risk, the first order of business may be a simple one: sign back into the app. Facebook logged everyone out of all 90 million accounts in order to reset digital keys the hackers had stolen - keys normally used to keep users logged in, but which could also give outsiders full control of the compromised accounts.  Which of the following points do not capture the negligence of Facebook in the most appropriate manner? Arguments: I. What Facebook knows so far is that hackers got access to the 50 million accounts by exploiting three distinct bugs in Facebook's code that allowed them to steal those digital keys, technically known as ‘access tokens’. The company says it has fixed the bugs.  II. The hack is the latest setback for Facebook during a tumultuous year of security problems and privacy issues . So far, though, none of these issues have significantly shaken the confidence of the company's 2 billion global users.  III. One of the bugs was more than a year old and affected how the ‘View As’ feature interacted with Facebook's video uploading feature for posting ‘happy birthday’ messages. But it wasn't until mid-September that Facebook noticed an uptick in unusual activity, and not until this week that it learned of the attack.
