DIFFERENCE BETWEEN UBUNTU and WINDOWS


Windows is a closed-source operating system, the majority of which is based only on software developed by Microsoft. Ubuntu is an open-source Linux-based operating system that uses a significant portion of the Debian Linux-based operating system. In turn, both of these operating systems use the Linux kernel, which is developed outside of either project. Ubuntu uses the Linux Kernel which is monolithic, Windows uses a hybrid Kernel. Ubuntu is based around the company Canonical and is also community based, Windows is strictly company based.

UBUNTU vs. WINDOWS

1. Bundled software
Windows 7 by default has very minimal software set, the basic features that we need – word processor, spread sheet and a presentation software are not present. You’ll have to purchase and install the MS Office suite separately, this is something that should be bundled with the operating system. The question I ask is “What good is an operating system, if it doesn’t provide the basic features?”
On the other hand  Ubuntu comes with the LibreOffice suite (a Microsoft Office Equivalent) preinstalled. It also has F-spot, an image editing program that and an Instant messaging client called Empathy – that has chat provisioning for Facebook, G-Talk, Yahoo,MSN and VOIP capabilities all under a single application.
Drivers – One of the biggest advantages of Linux is its built-in driver set, or rather the ability of automatically downloading and installing them. This includes the drivers for your webcam, Wi-Fi, Ethernet Card, even your printer or scanner! We all know drivers is a big pain that comes when completing a fresh install of Windows 7. With Linux, there is rarely any need to download the drivers manually. Linux also has the ability to download proprietary drivers (The ones from Nvidia and ATI), unlike windows where we have to manually download and install a driver for everything.

2. Media 
Windows comes with Windows media player, which is pretty much useless without codecs, as majority of the videos/movies that we watch require codecs like Xvid. So there is a need to download a codec pack before Windows media player becomes fully functional.
Ubuntu is bundled with Movie Player, and also requires downloading codecs.
However, in both the operating systems, it is very easy to watch videos by simply installing VLC media player.


3. Installing third party software
When it comes to installing third party software, the steps requires to install a software in Ubuntu is considerably less. An illustration is shown here of installing software in Ubuntu.

Ubuntu has a utility called Ubuntu software centre. This is one of the most loved features by Ubuntu users. It is as simple as installing an app in your phone from iTunes store or Android Market (now rebranded to Google Play). Just select the software that you need, hit install, and the software is ready to use.
However, an argument can be made for computers that don’t have internet access, ease of installing software in Windows outmatches as that of Ubuntu, as it is viewed a very complicated process that includes the terminal (command line interface). Although, it is very unlikely that someone will be without internet access these days.
4. Security 
I have been using Windows since windows the days of Windows XP, and I can tell you that Windows 7 has some pretty good security features that, if implemented properly, can give you quite a secure system to work with. Its firewall has advanced features that you can configure. However, there are many who believe that Windows still remains a weak operating system from a security standpoint.
Linux on the other hand , has always been a secure operating system since the early days. It has often been the subject of debate that an open source operating system cannot be as secure as a proprietary one, but Linux has proved  that belief to be untrue. Overall, I believe that Linux offers much more security by default.
5. Availability of Software
Since Ubuntu/Linux has a relatively less market share, availability of popular software for Ubuntu is a major concern. Some users are forced to stay with windows since their favorite software is not available on the Linux platform.Though this has recently changed and many commonly used  programs have now been ported to Ubuntu.
However, some advanced commercial software like the Adobe suite (Dreamweaver,Photoshop etc.) is not available on Linux, due to which, thousands of web developers and designers choose Windows over Linux.
6. Gaming
Gaming support is another aspect of an operating system. While Linux does have many games, it certainly cannot match Windows 7 in this area. Most of the high-end games have been built for the Windows platform, that make extensive use of Microsoft DirectX.

So its not hard to say that Windows 7 should be definitely your choice if you are a gamer.
7. Ease of use
This is the part that worries most users who are used to the Windows 7 User interface.

In case you are not pleased with the Ubuntu user interface, there is another distribution of Ubuntu called Kubuntu, which has a marvellous user interface,its very easy to use and is similar to the look and feel of Windows 7 in many aspects.
8. Cost
Windows 7 ranges from $100 to $300 depending on the version you are buying.

On the other hand, Ubuntu is free of cost. You can download it from the official website.

HISTORY of UBUNTU


Ubuntu Releases are made semiannually by Canonical Ltd, the developers of the Ubuntu operating system, using the year and month of the release as a version number. The first Ubuntu release, for example, was Ubuntu 4.10 and was released on 20 October 2004. Consequently, version numbers for future versions are provisional; if the release is delayed until a different month (or even year) to that planned, the version number will change accordingly.
Ubuntu releases are timed to be approximately one month after GNOME releases, which are in turn about one month after releases of X.Org, resulting in each Ubuntu release including a newer version of GNOME and X.
Every fourth release, in the second quarter of even-numbered years, has been designated as a Long Term Support(LTS) release, indicating that they are supported and receive updates for five years, with paid technical support also available from Canonical Ltd. However the desktop version of LTS releases before 12.04 were supported for only three years. Releases 6.06, 8.04, 10.04, 12.04, 14.04, and 16.04 are the LTS releases. Non-LTS releases prior to 13.04 have typically been supported for 18 months, and have always been supported until at least the date of the next LTS release. This has changed, however, for 13.04 and subsequent non-LTS releases, with the support period being halved to 9 months.

OPERATING SYSTEM


   OPERATING SYSTEM

  A software that manages computer hardware and software resources that provides common service for computer programs. It also acts an intermediary between programs and the computer hardware.


Examples of Modern Operating Systems
Windows Operating System

Is a metafamily of graphical operating systems developed, marketed, and sold by Microsoft. It consists of several families of operating systems, each of which cater to a certain sector of the computing industry.

ENVIRONMENT OF WINDOWS 95




UBUNTU Operating System

Is a free and open sourced Linux operating system.  Ubuntu means “human-ness” or “humanity towards others” in Southern African philosophy.
Open source software is software that can be freely used, changed, and shared (in modified or unmodified form) by anyone.

MS-DOS

Microsoft Disk Operating System (MS – DOS)

TIM PATERSON
Tim Paterson (born 1956) is an American Computer Programmer, best known for creating 86-DOS, an operating system for the INTEL 8086 that emulated the API of CP/M and which formed the basis of MS-DOS, the most widely used personal computer operating system in the 1980s. 

MS-DOS -> is an operating system with a command-line interface used on personal computers. It translates keyboard input by the user into operations the computer can perform, it also oversees operations such as disk input and output.
MS-DOS ENVIRONMENT


DOS COMMANDS

Internal Commands –> a command that resides memory whenever DOS is active. 

CD or CHDIR - This command lets    you change directories.


   Ex. C:\>CD windows
   The result will be
   C:\WINDOWS>

CD.. – moves one directory back. 

CD\ - moves back to the root drive of the directory.

VER – displays the MS-DOS version number.   
   Ex. C:\ver

TIME – displays and sets the system time. 
   Ex. C:\time

DATE -  This command lets you set your systems date. 
    Ex. C:\>date

DEL or ERASE – removes a file you want deleted.
    Ex. C:\>del file.exe

MD – creates a directory
     Ex. C:\ mda

RD – remove or delete directory
     Ex. C:\ rd directoryname

DIR - This command gives a listing of most of the files and directories on a disk.
    Ex. C:\ dir
/W - gives the directory listing wide across your screen without times, dates, and sizes listed
     Ex. C:\ dir/w

CLS – This command clears the screen
     Ex. C:\cls

COPY - This command obviously copies files to different spots on your disks. It does not remove the source file after writing the new file.
     Ex. C:\copy mystuff.doc A:

EXIT – closes the command prompt
     Ex> C:\exit

External Commands  – >a command that resides on disk.

 ATTRIB – Function to set or remove file attributes: (Read-Only, System, Hidden). These attributes are used by a wide variety of programs to protect and classify files.

S – System Files
H – Hidden Files
R – Read-Only files
[+] - adds the attribute
[-] – removes attribute
[/S] – also applies to files on sub directories of current directory
[/D] – applies on folders

Ex. ATTRIB –s –h –r /s /d g:\*.*
