There is a time in the development of the modern human where the cultural and societal turning points began to take place in the historical records. The now recognized shift from the late Upper Paleolithic era and Mesolithic era, to what we call the Neolithic era in history has more than just one factor that began to turn the wheels of social evolution.

The first OS we are going to look at is Linux, it can be a hard system to use and understand, if you have not used it before, you must have a good knowledge of computers in order to deal with Linux. Commands have to be typed in on the command line, and most people do not know or understand command line text. Linux does not have a great number of vendor selling their computer or software, so there is not a good support system for it.

| It is hard to understand the system of Linux because most people are not familiar

Linux is a trademark owned by Linus Torvalds [1]. It is an operating system which is powerful, free and inexpensive to own based on UNIX [1]. It is a POSIX-compliant with versions available to install in cell phones, supercomputers and most computing systems [1]. Linux is an open source program as its source code is available to the general public for use and the right to modify from its original design without any charges [1]. New code will be added to the next version made available with Linux if it is accepted as a universal improvement [1]. The code will continue to exist and developed by the user even if the company fails [1]. Moreover, updates for Linux are available every six months [1]. Nowadays, Linux is in constant development by

Windows and Linux provide a GUI (Graphical User Interface) and a command line interface. The Windows GUI has changed dramatically from Windows 3.1 to Windows 95, slightly to Windows 2000, big change to Windows XP and is scheduled to change again with the new version of Windows recently named Vista. Themes is a feature in Windows which lets you customize to an extent the look of your GUI. Linux typically provides two GUIs, KDE and Gnome. Of the major distributions, Lindows has made their user interface resemble Windows a lot more than the others. Text mode interface is also known as a command interpreter. Windows users know this as DOS prompt. It is called a shell in Linux. Windows has a single command interpreter but the different types of Windows have different interpreters. Linux, just as all versions of UNIX, supports multiple command interpreters, but Linux usually uses one called BASH (Bourne Again Shell). A few other shells are the C shell, ash shell, and the bourne shell.

What is Operating System Security, Operating system security is the process of ensuring OS integrity, confidentiality and availability also OS security refers to specified steps used to protect the OS from threats, viruses, worms, malware or remote hacker.

OS security allows different applications and programs to perform required tasks and stop unauthorized interference. OS security may be applied in many ways. We 're going to discuss following topics in this article. A brief description about security and what are the types of encryption and what is Authentication, One Time passwords, Program Threats, System Threats and Computer Security Classifications.

In many systems architecture, the kernel is the lowest level of software that interfaces with the hardware in a computer. In UNIX, users typically have no direct access to it. It is responsible for interfacing all applications that run in user mode including the physical hardware and allowing processes to get information from each other.
