Band 6+: The charts below illustrate the global market share of three computer operating systems (OS) compared to other systems from 2012 to 2015. Provide an overview of the information by identifying and describing the key details, and include comparisons where appropriate.

The given charts illustrate the distribution of global market profit among four different sectors: OS1, OS2, OS3, and other types of computer operating systems from 2012 to 2015.

Overall, the distribution tended to allocate to the “others” category in the initial year, whereas the OS1 held the largest share in the remaining period. Additionally, the distribution of OS2 and OS3 were less than the other categories throughout the period shown and maintained stable positions, except for the final year.

In 2012, nearly a half of global market share was captured by the other computer operating systems, approximately two and a half times higher than the mentioned systems. This figure showed a constant decrease over the years, reaching 15% in the final year. In contrast, OS1 displayed an uptrend over the period. Commencing at 20%, increased by over 2 times in 2015, reaching 52%.

For OS2 and OS3, the market share of these systems varied by around 10% and 18% in the mentiond period .
