Computer Science  Chapter  Operating Systems
              Seven




          FOR ONLINE READING ONLY




              Introduction

             You  use  Operating Systems(OS) regular basis on computers, tablets,
             smartphones, and even gaming consoles. In this chapter, you will learn the
             concept of operating systems and how application system performance is
             affected  by  operating  system  design.  Also,  you  will  learn  about  operating
             system design and performance. The competencies developed will enable you
             to solve challenges related to Operating Systems design and performance.

                       Case study 7.1: Photo sharing among club members




              Members of an active School Photography Club have recently returned from an
              amazing field trip to Serengeti National Park, where they took amazing pictures
              of the environment and wildlife. They now face a challenge of distributing
              their pictures to every student in the school. Members of the club use different
              devices  such as laptops,  tablets,  and smartphones  with various operating
              systems such as Android, MacOS and Windows to share photos of different
              events. Hundreds of photos were taken, in different formats (JPEG, RAW), and
              saved across individual devices. The club wants to share the photos online in
              a way that is easily accessible to everyone. They also want to ensure that the
              photos are organised, captioned, and properly credited to the photographers.
