What is a Unix System?
UNIX is an operating system that has multitasking and multi-user abilities. Unix contains a C programming language where the OS provides tools that perform well defined functions under a unified file system as a main communication technique. This custom OS has a hierarchical directory structure and the data blocks are allocated by inodes which are grouped into cylinder groups. These UNIX systems are best known in the market for their efficiency and performance.
UNIX systems are often used in high-end commercial businesses. Because of this, it can be devastating to have your system crash or worse, lose important data that make your company function.
