Study Notes
Operating Systems Overview
- Business client operating systems are designed for systems connected to manage business domain networks, where users log into a centrally managed server like the active directory server to access resources.
- Network operating systems (NOS) run on servers in business networks, such as Windows Server 2019 or Windows Server 2022, serving network resources to clients.
- Smartphone or tablet operating systems are designed for handheld mobile devices, with a focus on touch-operated interfaces, like Android and iOS.
- Operating systems can be open source (e.g., Linux, Android) or proprietary (e.g., Windows, MacOS, ChromeOS), with different rights and development models.
- Operating systems have a life cycle, starting with public beta programs for user feedback and bug reports before final release.
- After release, operating systems are supported for a designated period, with manufacturers providing software updates, security patches, and bug fixes.
- Extended support programs, available at an additional cost, can prolong the support period for certain operating systems beyond the standard timeline.
- When a system's support period ends, it is considered end of life (EOL), no longer receiving updates, security patches, or bug fixes, leaving it vulnerable.
- Organizations should be aware of their operating systems' EOL status and plan to replace aging systems with newer supported ones.
- For instance, Windows 10 will reach its end of life on October 14th, 2025, requiring users to upgrade to Windows 11 for continued support.
- The text prepares readers for the course section focusing on domain one, operating systems, providing an overview of different types of operating systems and their life cycles.
- It covers the significance of operating system support, user feedback, and the implications of end of life status for organizations and individuals.
