forensic computers are becoming increasingly popular in the digital age. With everything from crime investigation to civil disputes, forensic computers are essential in providing evidence in court. In layman’s terms, forensic computers are specialized tools used to collect and analyze electronic data. The process of collecting evidence from computers can be complex but, in general, it involves making a complete analysis of all data stored on the device. In this blog post, we will take a closer look at the basics of forensic computers and how they are used in the legal field.

Forensic computers play a significant role in our legal system, but it’s important to understand how they work. The following are some of the essential components that make up a forensic computer.


The hardware used in forensic computers is designed to make an exact copy of the digital data on the suspect computer. The technology used can be a write-blocker, which no changes to the original device, or a hardware write-blocker, which prevents data from being overwritten. The data is copied to a hard disk image, which can be analyzed at a later stage.


There are various software programs used in the forensic investigation process, such as Encase, Forensic Toolkit, and FRED (Forensic Recovery of Evidence Device). These tools enable the investigator to gather data from digital sources. They work by analyzing data, recovering deleted data, searching for keywords, and generating reports.

Chain of Custody

The chain of custody is an important part of the forensic process. It refers to the steps taken to maintain the integrity of evidence from the time it is collected until it is presented in court. It’s essential to maintain accurate records of all persons who handle the evidence and keep it secure. All the information gathered must be admissible in court, and any mishandling of evidence can lead to it being dismissed.

Admissibility of Evidence

The admissibility of evidence is crucial in court, and it must meet certain requirements to be considered admissible. The evidence must be reliable and relevant, it must have been acquired legally, and it should be presented in a clear and concise manner. Failure to meet these requirements can lead to evidence being dismissed.


Forensic computers play a vital role in our legal system, and they are essential in providing evidence in court. As technology continues to evolve, forensic computer processes and tools must also adapt. Understanding the basics of forensic computers can help legal professionals comprehend how electronic data is gathered and presented in court. By gathering data through the use of specialized hardware and software, maintaining a chain of custody, and ensuring the admissibility of evidence, forensic computer analysts can provide vital information to legal professionals in their quest for justice.
