Define several forms of metadata that can be useful to an investigation. How are valuable to an investigator?

Metadata is data about other data and can be used to provide context for an investigation. Some common forms of metadata include dates and times, location information, user accounts associated with a file or activity, file sizes, IP addresses, and communications records. Metadata can be incredibly valuable to an investigator as it provides key insights into the activities that are being investigated. For example, metadata can reveal which users were involved in suspicious activities or when those activities took place. Additionally, location information can help investigators determine where certain events occurred or narrow down suspects who may have been in the same vicinity at the time. Metadata can also help piece together timelines of events that otherwise might not be connected.
