In this chapter, we will explore how Julia interacts with the outside world, reading from standard input and writing to standard output, files, networks, and databases. Julia provides asynchronous networking I/O using the libuv library. We will see how to handle data in Julia. We will also explore Julia's parallel processing model.
In this chapter, the following topics are covered:
- Basic input and output
- Working with files (including CSV files)
- Using DataFrames
- Working with TCP sockets and servers
- Interacting with databases
- Parallel operations and computing
