Linux Admin

Duration : 30 Hours Training

Linux is a true 32-bit operating system that runs on a variety of different platforms, including Intel, Sparc, Alpha, and Power-PC (on some of these platforms, such as Alpha, Linux is actually 64-bit). There are other ports available as well, but I do not have any experience with them.
Linux was first developed back in the early 1990s, by a young Finnish then-university student named Linus Torvalds. Linus had a “state-of-the-art” 386 box at home and decided to write an alternative to the 286-based Minix system (a small unix-like implementation primarily used in operating systems classes), to take advantage of the extra instruction set available on the then-new chip, and began to write a small bare-bones kernel.
