Diploma in Operating Systems Alison Course GLOBAL - Digital Diploma

Learn about operating systems (OS) and how they manage computer hardware and software resources and provide common services for computer programs. Learn about operating systems (OS) and how they manage computer hardware and software resources and provide common services for computer programs by studying the course Diploma in Operating Systems.The course begins by introducing you to operating systems, where an OS sits in a computers system, hardware abstraction and resource management. You will learn about processes and system calls, the structure of an OS and how different CPUs work. The course reviews memory management methods such as virtual memory, and how memory functions when booting up a computer system. You will be introduced to processes, how they are stored in the computer system, how new processes are created and what happens when they are terminated. You will learn about the different types of interrupts and about programmable interrupt controllers for hardware interrupts. You will learn about system calls and CPU context switching. Next, the course covers the two different types of processes for scheduling. You will learn about different scheduling methods for single CPU systems their advantages and disadvantages, about scheduling for multiprocessor systems and about scheduling methods for Linux systems. The course covers how processes communicate and share data with each other, also known as Inter-process communication (IPC). You will learn about different software techniques for IPC and the different ways hardware works with IPC. You will learn about deadlocks and threads in an operating system. Finally, you will learn about different security goals for an operating system. The course reviews access control techniques and the components for developing an access control system. You will also learn about information flow policies, leaky states, and the Biba and Bell-LaPadula models. This course will be of great interest to computer science students and computer engineers, and anyone who wants to learn about computer operating systems.Perquisites: The learner will need an understanding of C programming and an understanding of computer organisation and architecture.
