Core

Hello, what is core ??
As I am the beginner of Redhat 6.1, I always face a problem, that is sometimes it will "automatically" make a file core on that folder which I activate the program.
Now my question is:
1) What is core
2) What is the use of core ?

A core is simply a file that contains what was in memory at the time that the core was dumped. By dumped I mean that the contents of memory were written out to disk. A core is used to debug program crashes. For example, netscape keeps crashing, when netscape crashes, the system dumps a core file, writes all that was in memory to a file named core. This core file can now be analyzed by developers to find out why the program crashed which will help them in fixing the problem. Cores are also dumped when a system crashes, if it weren't for core files, it would very difficult to debug system crashes.
