Computer forensics, also known as digital forensics, is the process of collecting, analyzing, and preserving digital evidence from computers, mobile devices, and other digital storage media in order to investigate and prevent crimes or other incidents involving digital data.

Computer forensics involves using a variety of tools and techniques to recover data, such as deleted files, internet history, and system logs, to help establish a timeline of events and identify potential suspects. It also involves analyzing data to identify patterns, anomalies, and other indicators of malicious activity.

Computer forensics is used in a wide range of investigations, including criminal cases, civil litigation, and corporate investigations. It can be used to investigate crimes such as hacking, fraud, and theft, as well as to investigate employee misconduct and other internal incidents.

The ultimate goal of computer forensics is to gather and analyze digital evidence in a way that can be presented in court or other legal proceedings, while preserving the integrity of the data and adhering to established legal and ethical standards.

Overall, computer forensics is an important field that helps to uncover and prevent crimes involving digital data, and requires specialized skills, training, and equipment to effectively collect and analyze digital evidence.
