Chapter 4 Forensics For Dummies Review Quiz

The correct answer is "off" because the sentence is asking what to do with the computer if it is turned off. "Off" is the appropriate response as it indicates that the computer should be left in its current state of being turned off.

To turn off the computer, one can simply pull the plug from the power source. This action will cut off the power supply to the computer and turn it off.

When surveying the scene, it is important to gather information and understand the context of the situation. Interviewing the owners and users before beginning allows for valuable insights and firsthand accounts that can aid in the investigation. This step helps in establishing a comprehensive understanding of the scene and the events that took place, enabling a more effective and focused investigation.

An off-road vehicle is not a tool that would typically be brought to a crime scene. While mechanical and hardware tools, seizure supplies, and specialized wireless equipment may be useful for collecting evidence or conducting investigations at a crime scene, an off-road vehicle is not directly related to these tasks. It is more commonly used for transportation in rugged terrains, which may not be necessary or relevant at a crime scene.

When using audio to record the scene, it is important to record your arrival information. This includes details such as the date, time, and location of your arrival at the crime scene. This information is crucial for establishing an accurate timeline of events and can be used as evidence in investigations. Recording your arrival information helps provide context and documentation of your presence at the scene, which can be helpful for corroborating your testimony or providing an alibi if necessary.

The three types of records mentioned in the answer are chain of custody, documentation of the crime scene, and documentation of your actions. Chain of custody refers to the chronological documentation of the custody, control, transfer, analysis, and disposition of physical or electronic evidence. Documentation of the crime scene involves recording and documenting the condition and details of the crime scene, including photographs, sketches, and notes. Documentation of your actions refers to keeping a record of the actions taken by law enforcement officers or investigators during the investigation process.

Bringing a government issued sidearm to a crime scene is not advisable because it can potentially contaminate the evidence or escalate the situation. Firearms should be handled by trained professionals such as law enforcement officers. Their presence at a crime scene can compromise the integrity of the investigation and may hinder the work of forensic experts in collecting accurate evidence. Therefore, it is best to leave firearms outside of a crime scene to ensure the safety of everyone involved and to maintain the integrity of the investigation.

The word "Zoom" is used to indicate that something is being magnified or brought closer, often in the context of visual or audio communication. By using Zoom, one can enhance the clarity of a conversation or presentation by being able to see or hear things more clearly. Therefore, the word "Zoom" is used in this context to suggest that it is being used to provide more clarity.

The fan is an essential component of a computer that helps to cool down the system by circulating air. When the computer is turned on, the fan starts running to prevent overheating. Therefore, if the fan is running, it indicates that the computer is on and functioning properly.

When transporting evidence, it is important to follow certain precautions. Leaving anything out in the sun can potentially damage or alter the evidence, so it should be avoided. Using rubber mats in the floor of the vehicle can help reduce electrostatic discharge (ESD), which can also affect the integrity of the evidence. Lastly, securing all evidence ensures that it does not move or get damaged during transportation, maintaining its reliability and chain of custody.

The term "volatile" refers to something that is prone to change or instability. In the context of the question, keeping power to volatile data devices means ensuring a continuous supply of electricity to devices that store data that is susceptible to loss or corruption if power is interrupted. This could include devices like RAM or cache memory, which require a constant power source to retain the data they hold.

Faraday bags are designed to block electromagnetic signals, including cellular signals, from entering or leaving the bag. This prevents a cellular device from transmitting data while it is inside the bag. The bag is made of a conductive material that creates a Faraday cage, which effectively blocks all external electromagnetic radiation. Therefore, Faraday bags stop a cellular device from transmitting data.

When recording a scene with video, it is recommended to use date/time stamps to keep track of when the video was recorded. Carrying spare batteries is important to ensure that the camera does not run out of power during the recording. Using a computer with an image and video viewer allows for easy playback and editing of the recorded video. Using a microphone helps to capture clear audio during the recording.
