Thrashing is caused by under allocation of the minimum number of pages required by a process, forcing it to continuously page fault. The system can detect thrashing by evaluating the level of CPU utilization as compared to the level of multiprogramming. It can be eliminated by reducing the level of multiprogramming.

It refers to the adverse effects occurring when the generation of reactive oxygen species (ROS) in a system exceeds the system's ability to neutralize and eliminate them; excess ROS can damage a cell's lipids, protein or DNA.

It is a useful system for small and home-based businesses. It captures information at the time the transaction takes place. These One-Write Systems are efficient because they eliminate the need for recopying the data and are compatible with electronic data processing if you should decide to computerize. Many small businesses rely totally on the One-Write System for simplicity and versatility. With only two pieces of paper, a check and a ledger, you get all the benefits of sound bookkeeping: accuracy, money distribution, check control, audit trail, running bank balance, and instant review.

The most important thing to do when checking a malfunctioning device is to be observant. Begin by talking to the person who reported the problem. You can obtain many clues from this person. Careful listening also is a good way to eliminate the user as a possible cause of the problems. Part of the technician's job is to determine whether the user could be the source of the problem -either trying to do things with the system that it cannot do, or not understanding how some part of it is supposed to work.

(This is an important question because it shows humility and gives you the opportunity to both address and eliminate an objection.)

triggers are automatically executed  where stored procedures have to be invoked by the application or user. Triggers are inherently a transaction. You are limited to three trigger actions per table where you can have an unlimited number of stored procedures. You can pass parameter information in and out of a stored procedure. You cannot do this directly with triggers. When you would use triggers versus stored procedures is not completely exact. A general rule is to use triggers for lower level enforcement of data integrity and stored procedures for processing business talks. If there are certain data integrity checks done for all procedures, use the code once in a trigger. this will eliminate the redundancy of  the same code that would have to exist in all of the stored procedures.
