• ▸ io Byte streams vs character streams
• ▸ io File vs Files and Path — classic I/O vs NIO.2
• ▸ io Buffered streams — why the wrapper matters
• ▸ io NIO channels and buffers — heap vs direct ByteBuffer
• ▸ io Memory-mapped files — when and why
• ▸ io Serialization — Serializable, serialVersionUID and transient
• ▸ io Custom serialization and deserialization risks
