Q#1

If a file system defines a cluster as six sectors, each cluster can store 24,576 bits of information. A byte comprises eight bits. Besides, a typical sector has 512 bytes (Saferstein, 2018). Thus, if a file system defines a cluster as six sectors, and every sector constitutes of 512 bytes, it follows that a cluster holds 3,072 bytes, that is, 512 bytes multiplied by six. Hence, a cluster constituted of six sectors is likely to store 3,072 bytes of information. For one to convert this amount of information into bits, he or she should multiply 3,072 bytes by eight, which results in 24,576 bits. This is justified by the notion that a byte is comprised of eight bits.

Q#2

Chain of custody refers to every person who came into possession of an item of evidence (Saferstein, 2018). Contrastingly, a chain of evidence reflects the tracking record commencing with detailed scene notes defining or describing where the investigators received or collected evidence. The chain of custody comes into consideration where an investigator finds a mobile phone at a crime scene, packages it in a plastic bag, and labels it by including his or her initials ad date of collection on the evidence tape seal (Saferstein, 2018). The parties that handle the evidence from that point must maintain a written record of its acquisition and disposition (Saferstein, 2018). The chain of evidence comes into play where the investigators create notes on who obtained the mobile phone, the exact location at the crime scene the evidence was found, the time it was collected, the person that secured the evidence, and the parties that had possession or control of the device.

Q#3

A SIM card, which abbreviates the Subscriber Identification Module card, is usually inserted into a mobile phone, which then identifies the user's account to the network, handles authentication, and offers storage for primary users information not mentioning network data (Saferstein, 2018).

The primary research question that must be answered is when is it a...
