Tasks:1. 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.2. 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). The resources must not be about the same operating system.
