1. Straight-through cable (39-40): connects the wire at pin 1 on one end of the cable to pin 1 at the other end of the cable; the wire at pin 2 needs to connect to pin 2 on the other end of the cable; pin 3 on one end connects to pin 3 on the other; and so on. (To create a straight-through cable‚ both ends of the cable use the same TIA pinout standard on each end of the cable.) Crossover cable: a cable that swaps the wire pairs inside the cable 2.

workplace behavior. From sole attention focused on environmental conditions of work in the initial illumination experiment‚ the Hawthorne studies extended to the first relay experiment to investigate effects of working environment‚ physical requirements‚ management‚ and social relations upon output. The subsequent studies were: the second relay experiment‚ which tested effects of incentive systems; the mica splitting experiment‚ which tested effects of rest pauses upon performance; the interviewing program

productivity. There were two other major sections of tests that were the most discussed in the Hawthorne Studies. They were known as the Relay Assembly Test Room and the Bank Wiring Observation Room (Greenwood et al.‚ 1983)‚ and also included two other tests‚ which were known as the Second Relay Assembly Group and Mica Splitting Test Room. But essentially it was the Relay Assembly Test Room that really produced the Hawthorne Effect (Parsons‚ 1978). All four tests‚ which have provided results that has baffled

------------------------------------------------- Application security Application security encompasses measures taken throughout the application’s life-cycle to prevent exceptions in the security policy of an application or the underlying system (vulnerabilities) through flaws in the design‚ development‚deployment‚ upgrade‚ or maintenance of the application. Applications only control the use of resources granted to them‚ and not which resources are granted to them. They‚ in turn‚ determine the
