Description
Operating Systems in the Certificate in Information Technology (CIT) equips learners with a working understanding of the software that manages computer hardware and runs applications. The book opens with the fundamentals of operating systems: what they are, their core functions, the types in common use and the popular systems that dominate the market. It then develops processes and threads, CPU scheduling, and memory management, before moving to virtual memory and paging, file systems and storage, and the challenges of concurrency, deadlocks and synchronisation. The closing chapter addresses operating system security and virtualisation. Its eight chapters follow the unit’s lessons step by step, each with practical exercises, a global scope discussion and current advances in technology, preparing the learner for further study and hands-on practice in computing.
