This period of time is called the restrike time. Restrike times for traditional probe-start MH lamps can take 15 minutes or longer, but restrike times for pulse-start MH lamps are generally much shorter (see Figure 4). According to manufacturers' literature, restrike times for pulse-start MH lamps can be more than twice as fast as for probe-start MH lamps.
Overview. Unix (officially UNIX) is a registered trademark of The Open Group that refers to a family of computer operating systems and tools conforming to The Open Group Base Specification, Issue 7 (also known as POSIX.1-2008 or IEEE Std 1003.1 - 2008).
One ingredient of an environment, therefore, is the operating system. But operating systems include a number of different parameters. For example, many operating systems allow you to choose your command prompt or a default command path. All these parameters taken together constitute the environment. Another term for environment in this sense is platform. (2) In DOS systems, the environment is an area in memory that the operating system and other programs use to store various types of miscellaneous information. For example, your word processor may use the environment area to store the location of backup files. You can view or modify the environment with the SET command.
