Without it, sending an email over a long distance would require the immediate availability of every node on the routing network to forward each message.

A log is a detailed, timestamped record of an event generated by an operating system, computing environment, application, server, or network device. Logs can include data about user inputs, system processes, and hardware states. Although cold storage and rehydration can mitigate high costs, it is inefficient and creates blind spots.
