File system Mounting

File-System Mounting
* The simple idea behind mounting file systems is to combine multiple file systems into one large tree structure.
* The mount command is given a file system to mount and a mount point (directory ) on which to insert it.
* Once a file system is mounted onto a mount point, any further references to that directory actually mention to the root of the mounted file system.
* Any files ( or sub-directories ) that had been saved in the mount point directory prior to mounting the new file system are now hidden by the mounted file system, and are no longer available. For this reason some systems only permits mounting onto empty directories.
* File systems can only be mounted by root, unless root has previously configured certain file systems to be mountable onto certain pre-determined mount points. (E.g. root may permits users to mount floppy file systems to /mnt or something like it. ) Anyone can run the mount command to see what file systems are currently mounted.
* File systems may be mounted read-only, or have other restrictions inflict.

* The traditional Windows OS runs an expanded two-tier directory structure, where the first tier of the structure separates volumes by drive letters, and a tree structure is implemented below that level.
* Macintosh runs a equal system, where each new volume that is found is automatically mounted and added to the desktop when it is found.
* More recent Windows systems permits file systems to be mounted to any directory in the file system, much like UNIX.

Introduction to C Programs

INTRODUCTION The programming language ‘C’ was developed by Dennis Ritchie in the early 1970s at Bell Laboratories. Although C was first developed for writing system software, today it has become such a famous language that a various of software programs are written using this language. The main advantage of using C for programming is that it can be easily used on different types of computers. Many other programming languages such as C++ and Java are also based on C which means that you will be able to learn them easily in the future. Today, C is mostly used with the UNIX operating system. Structure of a C program A C program contains one or more functions, where a function is defined as a group of statements that perform a well-defined task.The program defines the structure of a C program. The statements in a function are written in a logical series to perform a particular task. The most important function is the main() function and is a part of every C program. Rather, the execution o...

Performance

Performance ( Optional ) * The I/O system is a main factor in overall system performance, and can place heavy loads on other main components of the system ( interrupt handling, process switching, bus contention, memory access and CPU load for device drivers just to name a few. ) * Interrupt handling can be relatively costly ( slow ), which causes programmed I/O to be faster than interrupt driven I/O when the time spent busy waiting is not excessive. * Network traffic can also loads a heavy load on the system. Consider for example the sequence of events that occur when a single character is typed in a telnet session, as shown in figure( And the fact that a similar group of events must happen in reverse to echo back the character that was typed. ) Sun uses in-kernel threads for the telnet daemon, improving the supportable number of simultaneous telnet sessions from the hundreds to the thousands.   fig: Intercomputer communications. * Rather systems use front-end processor...

Mathematics

MATHEMATICS           Mathematics is the science that deals with shapes, quantities and arrangements. Archmedes is known as the father of Mathematics (287BC-212BC). Mathematics seek and use patterns to formulates new conjuctures.They resove truth or false by using mathematical proof. Mathematics developed by counting, calculation, Measurements, Shapes and motion of physical objects.  Definition Mathematics has no general accepted definition. Until 18th century Aristotle defined mathematics as "the science of quantity". Many mathematicans take no interest in definition they simply say "Mathematics is what Mathematican do". Three leading definition of mathematics today are logicist, intutionist, and formalist. Logicist - In terms of Benjamin peirce, the definition of mathematics in terms of logic are "the science that draws necessary conclusion" and also said that " All mathematics is symbolic logic" by Mathematician Rusell. Intutionist - L.E.J.Bro...
