Find two resources that explain aspects of IT Service Management. Title and Reference:COBIT versus ITILIBARAKI, S. 2014. COBIT versus ITIL [Online]. Available: http://blogs.technet.com/b/cdnitmanagers/archive/2014/04/06/cobit-versus-itil.aspx [Accessed 29/01/2015 2014].Summary:This resource is a blog entry discussing the differences between CoBIT and ITIL. I chose this resource as there is a lot of confusion about the way in which ITSM is applied and the distinction between the CoBIT and ITIL implementations is frequently unclear. Ibaraki explains that CoBIT provides the governance and metric structures while ITIL delivers on the actual mechanics and "how-to" processes. The author makes an interesting observation that it is wrong to simplify COBIT as providing the 'why' and ITIL providing the 'how' because both ITSM mechanisms have considerable overlap and both need to be used at the same time. I found this article very useful in explaining the differences and similarities between these two aspects of ITSM.The text briefly mentions USB and FireWire as hardware standards that provide a way of connecting and communicating with external devices. Collect and summarise two resources that explain and describe two other bus communication standards. You may find it helpful to use the search term "bus hardware standards". The resources must not be about the same technology/standard.Title and Reference:Summary:Title and Reference:When we think about operating systems, we tend to focus on desktop software such as Windows, Linux and OS X. However, our mobile phones also use operating systems. Collect and summarise two resources that describe specific operating systems that run on mobile phones (note: you can choose current or discontinued/legacy operating systems).
