Band 7+: 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 demonstrate comparisons between the world’s three operating systems (OS) and other systems over four years (2012-2015).

Overall, there was an upward trend in the percentage of OS1, OS2, but OS3 experienced no change over the period. Meanwhile, other systems had dropped significantly until 2015.

Taking a look at OS1 and OS2, these 2 globally shared systems went up from 2012 to 2015. A remarkable growth of 22% was seen in the proportion of OS1 in 2015, which was twice as high as its first figure at 20% in 2012. Similarly, it can be observed that the consumption of OS2 around the world slightly rose from 17% in the first two years to 18% in 2014 and 2015.

On the other side, the proportion of OS3 remained stable over the years, whereas other systems plummeted. In 2012, OS3 accounted for 15% but then slightly fluctuated between 10% and 12% in the next two years before climbing back to 15% in 2015. Meanwhile, 2015 witnessed a significant drop of 33% in the figure of other systems, which stood at 48% in 2012.
