Operating system
An operating system is system software that manages computer hardware and provides services and interfaces for application programs.
Learn Concurrent Programming with Go
An operating system is system software that manages computer hardware and provides services and abstractions for application programs.
- How it is used
- Frames concurrent programs as work managed through operating-system resources, processes, and threads.
- How deep it goes
- Explains resource allocation and job-state transitions without descending into operating-system internals.
- Examples
- Traces a UNIX string-search command through job, ready, CPU, and I/O waiting queues.
- What you can do after
- Evaluate/understand how time-sharing keeps CPUs productive while concurrent jobs wait for I/O.

Azure Security
An operating system is system software running inside a virtual machine that manages its virtual hardware and provides services for applications.
- How it is used
- Frames the operating system as a security-monitoring layer beneath applications and above Azure compute resources.
- How deep it goes
- Explains OS log collection through agents, then details AMA prerequisites and installation, but defers data collection rules to section 9.4.
- Examples
- Uses Windows and Linux VMs, AMA installation through Azure CLI, managed identities, HTTPS endpoints, and multiple Log Analytics workspaces.
- What you can do after
- Operate/configure OS monitoring on Azure VMs by installing AMA and preparing permissions, networking, identity, and workspace routing.
Grokking Concurrency
An operating system is system software that manages computer hardware resources and provides services for application programs.
- How it is used
- Places a management layer between applications and hardware for resource access, isolation, and concurrent execution.
- How deep it goes
- Traces system calls, hardware mediation, task isolation, and process-thread trade-offs without detailing operating-system implementation internals.
- Examples
- Uses a workshop manager, disk writing, and process-thread comparisons to make OS mediation and multitasking concrete.
- What you can do after
- Evaluate concurrency choices by relating application tasks to OS threads, processes, and available hardware.
Microsoft Azure in Action
An operating system is system software that manages computer hardware and provides services and execution facilities for applications.
- How it is used
- Runs custom software on virtual machines and defines the platform whose maintenance shifts to Azure in PaaS.
- How deep it goes
- Defines OS selection and responsibility boundaries, but stops short of explaining operating-system internals or administration.
- Examples
- Uses Windows Server, Linux distributions, Ubuntu LTS, and specialized Azure Marketplace images as selection examples.
- What you can do after
- Evaluate operating-system choices for VMs and understand when Azure maintains the OS in PaaS.
