Do you know that there is also an investigation happening in the computer world? This is called a computer forensics. It is like an investigation done by police and special agents to solve a crime. This type of analysis uses advanced technologies, applications, and hardware to solve a crime.
A computer forensic scientist does the job of solving a crime through analyzing data in a computer related to the incident. This may include email conversations, hidden and deleted files.
This is also the study of the flow of information on the computers, and the science interchanging communication from one PC to another. The result can be used by law enforcement agencies to support their evidence on the crime happened.
As you may know, computers process data and communicate through binary codes such as 1 and 0. It does not understand human language but it only translates them before processing. Using forensic science, it is easier to track the history and trace events related to the crime. Using analysis tools and utilities, a scientist can gather information to serve as additional evidence.

Most of us think that the data we deleted on the computer are permanently gone on the computer storage. Actually, simply pressing the delete key on your keyboard just deletes the file location on the index database of the hard disk but not the actual data itself. With the use of an effective data recovery tool, files you deleted even months ago can be retrieved.
Tracking of emails, instant messaging, and any type of communication being used by human is also one aspect of computer forensics. Also, with the use of packet sniffers, this software can get information in real-time, once placed in a convenient data stream. Data being sent from one computer to another can be captured easily.
Computer forensics can be used to provide supporting information and evidence to solve a problem. Law enforcement authorities will benefit from this technology being offered by advanced technologies and techniques.
Anyone with the perseverance and skills can try to learn this career. When it comes to outsourcing, you do not need to hire a computer expert working remotely on the other side of the world due to the confidentiality of data.
