     See first by looking at the options it is clear that (A),(B)and (C) will or can interrupt a running process.

     A: device by generating interrupt.

     B: Timer is an anther implementation.A mechanism is needed whereby activities can be scheduled to run at some relatively precise time. Any microprocessor that wishes to support an operating system must have programmable interval timer which periodically interrupts the processor.

     and

     C:Scheduler is clear and obvious. now coming to

     D: in case of a power failure the whole system will shut down, nothing will run. While interrupting means that "stopping some process and running some other procedure." while as power failure will stop everything not interrupt a process. Hope you got it :)

   • Which of the following is the most precise classification of a problem X?

     Top Answer

     Answered Jan 11, 2011 · 2 votes

     NP or P means whether it can be solved in polynomial time in a non deterministic machine(NP) or in a deterministic machine(P). This reflects the complexity of the problem but not the complexity of an algorithm that solves the problem.

     While O(n^2) means that the algorithm being analyzed to solve a problem has an upper bound of n^2 complexity when n is the input.

     Theta(n^2) is also a way of expressing the complexity of an algorithm used to solve a problem but Theta(n^2) in contrast of O(n^2) means that that the lower and upper bound of complexity is n^2.

     There's also another measure which is o(little-oh) which indicates the lower bound complexity of an algorithm.

     Theta is more precise because like O(n^2) means just upper bound, the algorithm is also O(n^3) and O(n!).

   • Which of the following SQL queries finds sids of all the students who apply for CS but not for ME?

     Top Answer

     Query A return duplicate entries. This query does a self join which creates duplicate rows. To remove this, you have to use a group by which is not done here.

     Select A1.sid from Apply A1,Apply A2 where A1.sid = A2.sid and A1.major = 'CS' and A2.major <> 'ME' group by A1.sid-

     Therefore Answer B is the correct Answer

   • Which of the following is the reason for encouraging cheap and affordable sources of credit?

     Cheap credit or affordable credit refers to credit that is easily available to those with average earnings. It is intended to assist individuals who require assistance obtaining typical credit from institutions such as banks. 

     Reasonably priced credit options could consist of loans with lower rates of interest, longer repayment terms, and smaller amounts. They may also have more adaptable requirements, making it simpler for those with lower credit scores to qualify. 

     Affordable Credit 

     Examples of Cheap and Affordable Credit

     Credit Unions

     These provide monetary services to less privileged communities, including low-cost loans. Credit unions are like uber-cool money clubs that are run and owned by the people who use them. And the best part? They aren’t just about making cash. Nope, credit unions are all about helping you save up or borrow what you need without charging you loads of fees or high-interest rates. They’ve got everything from basic checking and savings to loans and credit cards, all for their members.

     PALs

     PALs are short for Payday Alternative Loans. These little loans are given out by credit unions instead of those sketchy payday loans that cost way...

   What is DNS & how does it work?

   • At its simplest, DNS is like that for the internet. All internet servers work on Internet Protocol (IP) addresses, which mostly look like several sets of numbers separated by periods (e.g. 123.456.789.100) though other variations exist. The domain name system was not always the default for accessing information of the web.

   How does a DNS resolver work?

   • When the user enters any specific domain name (eg. www.geeksforgeeks.org) in the web browser, the browser sends the DNS resolution request to the local DNS server. It mainly checks its cache for the IP address corresponding to the domain name. If the IP address is not cached, then the resolver forwards the request to the root DNS servers.

Any device connected to the internet - laptops, tablets, mobile phones - contains an IP address like 93.184.216.34 for identification, but this is obviously, not easy to remember.
