Operating Systems and Applications
Have you wondered how your computer keeps everything running smoothly, secures your files, or lets you launch apps with a click or command? Whether you’re a tech enthusiast, future sysadmin, or just curious about what happens beyond the desktop, this course offers an engaging journey into operating systems and applications.
Behind the Screen: Exploring Operating Systems and Applications
Join instructor Alan as you lift the veil on the heart of modern computing—the operating system. You’ll explore how the OS works as the crucial link between hardware and your favorite applications, managing everything from security to storage. With practical insights and real-world examples, you’ll see how the invisible “conductor” behind your computer, phone, or tablet orchestrates a seamless experience.
What You’ll Learn:
OS Overview
Discover the OS as the powerful software layer that manages all your hardware and applications. Trace the history of operating systems, learning how key developments—from early command-line interfaces to today’s sophisticated systems—shaped the devices we use. Identify the main OS components, from the kernel to user interfaces, and explore how each part contributes to system stability and function.
Security
Learn how operating systems control access with user accounts and file permissions, ensuring only the right people see sensitive data. Explore how operating systems apply updates and patches to secure your system, and get familiar with built-in tools like firewalls and antivirus software that protect you from threats. See how system hardening reduces vulnerabilities, helping keep your device safe.
User Interfaces
Compare graphical interfaces and command-line tools for interacting with your OS, and discover how each approach helps you control your system. Understand how you launch and manage applications through the OS, and see how system services and APIs provide programs with essential resources. Explore how the OS manages input and output, making devices accessible to everyone.
Managing Resources
Step inside the OS’s resource manager and see how it schedules CPU time, allocates memory, and keeps devices working together. Understand the concepts of processes, threads, and context switching that allow multitasking and smooth performance. Learn how the OS responds to hardware events using interrupts and device drivers.
File Management
See how operating systems organize the information you create and use every day—using files, folders, and structured paths. Discover common file system types and why different systems prefer different file organizations. Understand how file permissions allow or restrict access, balancing usability and security.
Throughout the course, you’ll connect technical concepts to everyday technology, bridging theory and practice. As part of the KodeKloud community, you’ll collaborate with others and build confidence in managing and understanding operating systems.
