How does Go handle distributed systems and networking?

Go provides several built-in packages and tools for building distributed systems and networking applications. Some of the most commonly used packages for networking include:

**net** package: The **net** package provides a foundation for network programming in Go. It includes functions and types for creating and interacting with network connections, resolving domain names, and working with network addresses.

**http** package: The **http** package provides a set of functions and types for building HTTP clients and servers. It includes support for HTTP request and response handling, routing, and middleware.

**grpc** package: The **grpc** package provides support for building high-performance, scalable, and interoperable RPC (Remote Procedure Call) services. It uses the Protocol Buffers data format for message serialization, and provides built-in support for load balancing and service discovery.

**bufio** package: The **bufio** package provides buffered I/O functionality for reading and writing data over a network connection. It can improve performance by reducing the number of system calls made during I/O operations.

In addition to these packages, Go also provides support for concurrency and parallelism, which can be useful in building distributed systems. Goroutines, channels, and the **sync** package can all be used to build highly concurrent and scalable systems. The Go runtime also includes a garbage collector and support for lightweight threads (or "goroutines"), which can help reduce the memory overhead of running many concurrent tasks. Overall, Go's support for distributed systems and networking makes it a popular choice for building cloud-native applications and microservices.
