1. Energetic Particles
... Energy . ... The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much, much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ... Typical energy of an electron in the polar aurora. 40,000 ev . ... 50,000 ev . ...

19. Processes
When you enter a command it invokes a program. While this program is running it is called a process . It is important to grasp that although there is only one copy of a program held in the file system , any number of processes can be invoked which run this program. When the operating system is started after a boot , a single process is started. ... Any processes that are started from within your shell - such as entering a command - are the children of this process. ...
