Ans. Linux is‚ in simplest terms‚ an operating system. It is the software on a computer that enables applications and the computer operator to access the devices on the computer to perform desired functions. The operating system (OS) relays instructions from an application to‚ for instance‚ the computer’s processor. The processor performs the instructed task‚ then sends the results back to the application via the operating system. Following are some of the important features of Linux Operating

DRAFT as of November 19‚ 2010: Copyright 2009 Cox‚ Kaashoek‚ Morris Chapter 7 File system data structures The disk driver and buffer cache (Chapter 6) provide safe‚ synchronized access to disk blocks. Individual blocks are still a very low-level interface‚ too raw for most programs. Xv6‚ following Unix‚ provides a hierarchical file system that allows programs to treat storage as a tree of named files‚ each containing a variable length sequence of bytes. The file system is implemented in four layers:

The History of Linux began in 1991 with the commencement of a personal project by a Finnish student‚ Linus Torvalds‚ to create a new operating system kernel. Since then the resulting Linux kernel has been marked by constant growth throughout its history. Since the initial release of its source code in 1991‚ it has grown from a small number of C files under a license prohibiting commercial distribution to its state in 2009 of over 370 megabytes of source under the GNU General Public License.

heavy workloads. With the current spreading trend of open-source‚ and tools readily available‚ Linus began developing an operating system that was a deviation for MINIX. He used resources made available through the GNU project (known as GNU’s Not Linux)‚ which was a developmental stage of a UNIX-type operating system that was open source. He kept the file system structure‚ and ported bash(1.08) as well as gcc(1.40)‚ for "practical reasons". Once a small
