  Ansible is an open-source automation tool used for: Configuration Management (installing & configuring software) Application Deployment (deploying apps to multiple servers) IT Orchestration (managing complete workflows across servers) It allows you to automate tasks on many servers at once using simple YAML playbooks. 📌 Key Points in the Definition: Agentless → Unlike tools like Puppet or Chef, Ansible doesn’t need any special agent software installed on the target machines. Uses SSH/WinRM → Connects to Linux servers via SSH and to Windows servers via WinRM . Idempotent → If you run a playbook multiple times, it won’t break anything—it ensures the system reaches the desired state. Human-Readable → Uses YAML syntax, easy for beginners. 📌 Example in One Line: 👉 Ansible is like a remote controller for your servers—it lets you install, configure, and manage 1000+ systems just by writing a few lines of YAML code. Step 1: Install Minimal U...

  C# Interview Questions (50) 1. What is C#? Answer: C# is a modern, object-oriented programming language developed by Microsoft, running on the .NET framework. It’s used for building Windows applications, web services, and games via Unity. 2. Explain value types vs. reference types. Answer: Value types (e.g., int , struct ) store data directly in memory, while reference types (e.g., class , string ) store references to memory locations. Value types are stack-allocated; reference types are heap-allocated. 3. What is boxing and unboxing? Answer: Boxing converts a value type to a reference type (e.g., int to object ). Unboxing converts a reference type back to a value type. Both impact performance due to memory overhead. 4. What is the static keyword? Answer: static declares members (methods, fields) that belong to the type itself, not instances. A static class cannot be instantiated. 5. Explain delegates. Answer: Delegates are type-safe function pointers that reference meth...
