Linux File System

 

File System

Linux treated everything as a file. Ever a directory is treated as a file and contains entries for several other files. All the hardware devices, such as (input/output) I/O devices, storage devices, etc. are all treated as files.

The Linux file system is organised in a hierarchy which start with the root directory. The root directory is represented by forward slash (/) under the root directory there are several system directories and the name directory.

    • /bin: - This directory contains executable program file (binary file). This directory contains all the commands of Linux in the same way as all the commands of DOS are stored in the Command.Com file.
    • /dev: - This directory contains the special device files for example, the printer may be a file known as prn in this directory. The hard disk may be hda file and its first partition would be hda.
    •  /etc: - This directory contains all the system wise configuration information as text files.
    • /lib: - This directory contains the library files. Library files contain the reusable functions and routines for the programmer to use.
    • /tmp: - This directory contains all the temporary files, which will be deleted from the system.
    • /usr: - This directory contains the home directories of the users there is one home directory for each other.
    • /kernel: - This directory contains all the kernel specific codes. Kernel is the heart of the Linux system. It is responsible for resources allocation security and low level hard ware interfaces.
    • /mnt: - This is the directory where the storage devices other than the hard disk (floppy disk and CD) are mounted. This directory contains the sub directories ‘floppy’ and ‘cdrom’ which when these devices are mounted show the contents of the CD-ROM of floppy disk, respectively.

Difference between Compiler and Interpreter

Difference between Compiler and Interpreter Do you ever hear about Compiler and Interpreter? These are the programs which translates the high level language into machine language. Let’s know more about these programs. Compiler A program that translates high level language program into machine language program is known as compiler. It checks all kinds of limits, ranges, errors etc. But its program execution time is more and occupies a larger part of the memory. It has low speed and low efficiency of memory utilization. If a compiler runs on a computer for which it produces the object code it is known as a self or resident compiler , If a compiler runs on a computer other than that for which it produces object code, it is known as a cross compiler . The compiler derives its name from the way it works, looking at the entire piece of source code and collecting and reorganizing the instructions. Compilers require some time before an executable program emerges. However, programs prod

History of Computers

History of Computers History means the systematic information (study) about the past of anything under the topic history of computers followings are some important points. 1) Abacus      Abacus means a calculating board. It is known as the first calculating machine invented by Tim  Cranmer . It  was first developed by China. It is still commonly used by the peoples who are blinds. It is also known as Cranmer's Abacus.       2) Pascal's Adding Machine     In 1642 French scientist and philosopher Blaise Pascal .invented the first practical mechanical            calculator. It was known as adding machine that could Add and Subtract. It is also called  Pascaline.   3) Gott fried Leibniz     In 1671 , German mathematician and philosopher Gottfried Wilhelm Leibniz develops an advance    version of pascal's adding machine. It could Add, Subtract as well as Multiply, Divide and workout         Square root. 4) George Boole       George Boole invented a new branch of mathematics
