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...

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 direc...
