  • 1. Q.1 What is the difference between Unix and windows operating system. ?Ans.What is it?Unix is an operating system that is very popular in universities, companies, big enterprises etc.Windows is the family of operating system (OS) from Microsoft, which is the most famousOS in the world.Development and Distribution:Unix systems are divided into various other flavours, mostly developed by AT&T as well asvarious commercial vendors and non-profit organizations.Windows is developed and distributed by Microsoft.Inception:In 1969, Unix was developed by a group of AT&T employees at Bell Labs and DennisRitchie. It was written in “C” language and was designed to be a portable, multi-tasking andmulti-user system in a time-sharing configuration.Windows first released in 1985.Market share for Desktop PC:Unix has less than 0.5 per cent of the PC market.As on 2007, 92.63% of PC users from all over the world run Windows OSGUI:Initially Unix was a command based OS, but later a GUI, popularly known as X Window wascreated for UNIX.The Windows GUI is an integral component of the OS and it is mainly influenced by AppleMacintosh OS and Xerox.Threat detection and solution:In case of Unix, user has to wait for a while, to get the proper bug fixing patch.After detecting a major threat in Windows OS, Microsoft generally releases a patch that canfix the problem and it can take more than 2/3 months. Sometimes sooner, Microsoft releasespatches and updates weekly.Cost:Different flavours of Unix have different cost structuresFor desktop or home use, Windows can be expensive. A single copy can cost around $50 to $450 depending on the version of Windows.Security:A rough estimate of Unix viruses is between 85 -120 viruses reported till date.According to Dr. Nic Peeling and Dr Julian Satchells “Analysis of the Impact of Open Source
  • 2. Software” there have been more than 60,000 viruses in WindowsUser:Unix operating systems were developed mainly for mainframes, servers and workstations.The Unix environment and the client-server program model were essential elements in thedevelopment of the Internet.Windows operating system is developed for general users for home use as well as forcorporate users.Q.2 What is the difference between UNIX and LINUX?Ans.
  • 3. Inception:Linux is based on UNIX and eventually after adding many features of GUI, Drivers etc. LinusTorvalds developed the framework of the OS that became LINUX in 1992. The LINUXkernel was released on 17th September, 1991In 1969, Unix was developed by a group of AT&T employees at Bell Labs and DennisRitchie. It was written in “C” language and was designed to be a portable, multi-tasking andmulti-user system in a time-sharing configuration.Market share for Desktop PC:The market share of Linux is about 0.8%Unix share is Less than 0.5 per cent of the PC market.GUI:Linux typically provides two GUIs, KDE and Gnome. But Linux GUI is optional.Initially Unix was a command based OS, but later a GUI, popularly known as X Window wascreated for UNIX.Threat detection and solution:In case of Linux, threat detection and solution is very fast, as Linux is mainly communitydriven and whenever any Linux user post s any kind of threat, several developers startworking on it from different parts of the worldIn case of Unix, user has to wait for a while, to get the proper bug fixing patch.Cost:Linux can be freely distributed, downloaded freely, distributed through magazines, Books etc.There are priced versions for Linux also, but they are normally cheaper than Windows.Different flavours of Unix have different cost structuresSecurity:Linux has had about 60-100 viruses listed till dateA rough estimate of Unix viruses is between 85 -120 viruses reported till date.What is it?Linux is an example of Open Source software development and Free Operating System (OS).Unix is an operating system that is very popular in universities, companies, big enterprises etc.Development and Distribution:Linux is developed by Open Source development i.e. through sharing and collaboration ofcode and features through forums etc. and it is distributed by various vendors such as Debian,Red Hat, SUSE, Ubuntu, GentuX etc.Unix systems are divided into various other flavours, mostly developed by AT&T as well asvarious commercial vendors and non-profit organizations.

But Linux GUI is optional.The Windows GUI is an integral component of the OS and it is mainly influenced by AppleMacintosh OS and Xerox.Text mode interface:Linux users refer to it as Shell and it can support multiple command interpreters.Windows use DOS prompt and each version of Windows has a single command interpreter,recently there is the addition of the optional PowerShell.Threat detection and solution:In case of Linux, threat detection and solution is very fast, as Linux is mainly communitydriven and whenever any Linux user post s any kind of threat, several developers startworking on it from different parts of the worldAfter detecting a major threat in Windows OS, Microsoft generally releases a patch that canfix the problem and it can take more than 2/3 months.
