Linux Basic Features and Architecture

Basic Features

Following are some of the important features of Linux Operating System.
  • Portable − Portability means software can works on different types of hardware in same way. Linux kernel and application programs supports their installation on any kind of hardware platform.
  • Open Source − Linux source code is freely available and it is community based development project. Multiple teams work in collaboration to enhance the capability of Linux operating system and it is continuously evolving.
  • Multi-User − Linux is a multiuser system means multiple users can access system resources like memory/ ram/ application programs at same time.
  • Multiprogramming − Linux is a multiprogramming system means multiple applications can run at same time.
  • Hierarchical File System − Linux provides a standard file structure in which system files/ user files are arranged.
  • Shell − Linux provides a special interpreter program which can be used to execute commands of the operating system. It can be used to do various types of operations, call application programs. etc.
  • Security − Linux provides user security using authentication features like password protection/ controlled access to specific files/ encryption of data.

Linux History and GNU

Linus Torvalds ,a student at the University of Helsinki started developing Linux to create a system similar to MINIX, a UNIX operating system. In 1991 he released version 0.02; Version 1.0 of the Linux kernel, the core of the operating system, was released in 1994. About the same time, American software developer Richard Stallman and the FSF made efforts to create an open-source UNIX-like operating system called GNU. In contrast to Torvalds, Stallman and the FSF started by creating utilities for the operating system first. These utilities were then added to the Linux kernel to create a complete system called GNU/Linux, or, less precisely, just Linux. Linus Torvalds Richard Stallman Linux grew throughout the 1990s because of the efforts of hobbyist developers. Although Linux is not as user-friendly as the popular Microsoft Windows and Mac OS operating systems, it is an efficient and reliable system that rarely crashes. Combined with Apache, an open-source Web server, Linux accounts fo

Introduction to Data Structures

Visit My Data Structure Blog for Programs... It is important for every Computer Science student to understand the concept of Information and how it is organized or how it can be utilized. If we arrange some data in an appropriate sequence, then it forms a Structure and gives us a meaning. This meaning is called Information . A data structure is a particular way of storing and organizing data in a computer so that it can be used efficiently. Data may be organized in many different ways. The logical model of a particular organization of data in a computer is called data structure. The choice of the model based on two considerations. It should be reflect the data in the real world. It should be simple that one can effectively process the data when necessary. E.g. Array, linked list, stack, queue, tree, graph Data structure can be classified into two: Linear: A data structure is said to be linear if its elements form a sequence E.g. Array, linked list, stack, queue Non-Linear: A dat

Basic Linux Commands For Beginner's

Basic Linux Commands for Beginners Linux is an Operating System’s Kernel. You might have heard of UNIX. Well, Linux is a UNIX clone. But it was actually created by Linus Torvalds from Scratch. Linux is free and open-source, that means that you can simply change anything in Linux and redistribute it in your own name! There are several Linux Distributions, commonly called “distros”. A few of them are: Mint Ubuntu Linux Red Hat Enterprise Linux Debian Fedora Kali Linux is Mainly used in Servers. About 90% of the Internet is powered by Linux Servers. This is because Linux is fast, secure, and free! The main problem of using Windows Servers are their cost. This is solved by using Linux Servers. Forgot to mention, the OS that runs in about 80% of the Smartphones in the World, Android, is also made from the Linux Kernel. Yes, Linux is amazing! A simple example of its security is that most of the viruses in the world run on Windows, but not on Linux
