+
+Temporal provides a comprehensive platform for building distributed applications with a focus on durability and reliability. 
+
+## Resilient applications by default
+
+Temporal ensures your applications are reliable by default, handling everything from minor network outages to significant issues like unexpected reboots, or hardware failures.
+By offloading the responsibility of failure management from the application to the platform, this removes the need for extensive coding, testing, and maintenance tasks. 
+
+This shift simplifies the development process and enables your application to seamlessly recover from disruptions. 
+It does so by automatically reconstructing its previous state. 
+Your application logic can be recovered, replayed, or paused from any previous point in the application process.
+
+
+## How It Works

+
+### Workflow
+A Temporal application is the code you write, comprised of Workflow and Activities. Workflows are defined as code: either a function or an object method, depending on the language. 
+A Temporal Workflow defines your overall business logic. That business logic might involve moving money between bank accounts, processing orders, deploying cloud infrastructure, training an AI model, or something else entirely. 
+The Worker runs the Workflow and Activity code. 
+

+
+### Activity
+Activities are functions which encapsulate logic that can potentially fail, such as network calls, file operations,  or random number generation. 
+Activities are invoked in Workflow code and the Temporal Service coordinates with the application to execute them.
+

+
+### Temporal Service
+Temporal consists of two components, the [Temporal Service](/evaluate/major-components#temporal-service) and an SDK in your preferred language such as Go, .NET, Java, Python, PHP, or Typescript. 
+The Temporal Service logs the progress and state of your application. 
+Once the application finishes executing the Activity, it communicates with the Temporal Service, which records the Activity's completion in the Workflow's Event History. 
+The Activity invocation is handled by the Temporal Service. 
+The Temporal Service updates the Event History and creates a Task for executing the Activity.
+

+
+### Recovering from Failure
+A Temporal Workflow is basically a process or sequence of events you want to make sure will execute reliably. 
+They can run—and keep running—for years, even if the underlying infrastructure fails. 
+If the execution of your Workflow code crashes, Temporal automatically recreates its pre-crash state, allowing the Workflow to continue execution as if it never even happened. 
+Temporal provides built-in solutions for timers, event sourcing, state checkpointing, retries, and timeouts, removing the necessity for custom implementations.
+

+
+### Concluding the Workflow
+In this example, there are two Activities. The second Activity is complete, but the Workflow function still has additional code to run. 
+The Temporal Service creates a new Task requesting that the application run the additional code.
