what is linux operating system ?
Linux is a ‘Unix’ like computer operating system that assembled under a model of free and open source software development and distribution. This operating system was originally developed as a free operating system for Intel x86-based personal computers and been ported to more computer hardware platforms than any other operating system. 

what is windows operating system ?
Windows is a family of operating systems for personal computers. Windows dominates the world’s personal computer, running by some estimates  on more than 90%  of all personal computers. Examples of windows :
1.WINDOWS 1.0-2.0 (1985-1992)
Introduced in 1985, Microsoft Windows 1.0 was named due to the computing boxes  or windows that represented a fundamental aspect of the operating system. Instead of typing MS-DOS commands, windows 1.0 allowed users to point and click to access the windows.
2.WINDOWS 8(2012)
Completely redesigned operating system that have been developed from the ground up with touch screen use in mind as well as near instant on capabilities that enable a Windows 8 PC to load and start up in a matter of seconds rather than in minutes.

UNIX operating system ?
Unix is a popular multitasking operating system which developed at Bell Labs in the early 1970. UNIX was created to be a small, flexible system used exclusively by programmers. UNIX was one of the first operating systems to be written in a higher level programming language namely C. This mean that it could be installed on virtually any computer for which a C compiler existed.

SCL 3: OPERATING SYSTEM AND FILE MANAGEMENT
1)List down all the operating system used in a desktop/laptop today and find good descriptions of how operating system work?Hence,state their advantages and disadvantages.
                ADVANTAGES
                DISADVANTAGES
 UNIX OPERATING SYSTEM
        · Provides true multi-user,   multitasking,protected memory operation,while using a minimal amount of memory.
   · Unix provides solid user security via its account validation and authentication.
   .  In unix ,everythings is a file,including the terminal  and devices,which means it can run on a number of different hardware platforms,making it easy for users to install on whatever hardware they choose to use.
      

    ·  Documentation on many of these tools is hard to find,and is also incomplete.
    · Not a very user friendly operating system.
    · Its basic interface is the command line and even experienced users can make mistakes using this interface.
    · It can be cryptic and even though   there are numerous utilities and applications for unix platforms which can be too much for someone new to unix.
WINDOWS OPERATING SYSTEM
    · Easy to use,especially for new computer users,plenty of help resources are available online.
    · It has a large library of available software,games,and utilities.
    · Hardware manufacture all make drivers and support for windows operating system.

    · Can be expensive.
    · Lags behind it competitors
    · Openess to virus attacks is a major disadvantages.
MAC OPERATING  SYSTEM
   · Mac is a much more secure OS,and is far less open to viruses and malware.
   · Stability is a major advantages.
   · It very rarely crashes,loses data or freezes.
    ·  It is  expensive operating system.
    ·  Mac computer are more expensive generally than PC’s.
      
LINUX OPERATING SYSTEM
    · It is  an open source operating system,which in most cases is free.
    ·   It is very reliable and rarely freezes.
    ·  Many programs are free or open source,even the very complex ones.
    · Fewer computer programs,games,utilities are available for linux.
    · The open source nature of linux allows more advanced users to customise the code as they wish.
    · Inexperienced computer users may find  it more difficult to get grips with linux.
   · There are still some manufacture that not offer hardware support for linux operating system,although there are fewer every years.
   · Only a few people use Linux,therefore it is more difficult to find someone familiar with it although there are vast resources online.
CHROME OPERATING SYSTEM
    · Consistent and stable operating system.
   · Pages and applications are running isolated in memory from others.
   · Perfect for novice users.
   · It is fast when it is used.
   ·  The newest generation of chromebooks have recorded 7 seconds to fully load the operating system from boot up.
    · It is very difficult to run all of the programs if there is issues on internet connectivity seeing that many operations require a stable connection to the internet to perform.
    · Chromebooks running chrome operating system are unable to perform types of offline leisure like playing games,image editing and programming making operating system less useful for those who want more out of their computers.
