We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

In 1992, the term Computer Forensics was used in academic literature.
1995 International Organization on Computer Evidence (IOCE) was formed.
In 2000, the First FBI Regional Computer Forensic Laboratory established.
In 2002, Scientific Working Group on Digital Evidence (SWGDE) published the first book about digital forensic called “Best
practices for Computer Forensics”.
In 2010, Simson Garfinkel identified issues facing digital investigations.
Objectives of computer forensics
Here are the essential objectives of using Computer forensics:
It helps to recover, analyze, and preserve computer and related materials in such a manner that it helps the investigation agency
to present them as evidence in a court of law.
It helps to postulate the motive behind the crime and identity of the main culprit.
Designing procedures at a suspected crime scene which helps you to ensure that the digital evidence obtained is not corrupted.
Data acquisition and duplication: Recovering deleted files and deleted partitions from digital media to extract the evidence and
validate them.
Helps you to identify the evidence quickly, and also allows you to estimate the potential impact of the malicious activity on the
victim
Producing a computer forensic report which offers a complete report on the investigation process.
Preserving the evidence by following the chain of custody.

3. Process of Digital Forensics
Let’s study each in detail
Identification
It is the first step in the forensic process. The identification process mainly includes things like what evidence is present, where it is stored,
and lastly, how it is stored (in which format).
Electronic storage media can be personal computers, Mobile phones, PDAs, etc.
Preservation
In this phase, data is isolated, secured, and preserved. It includes preventing people from using the digital device so that digital evidence is
not tampered with.
Analysis
In this step, investigation agents reconstruct fragments of data and draw conclusions based on evidence found. However, it might take
numerous iterations of examination to support a specific crime theory.
Documentation
In this process, a record of all the visible data must be created. It helps in recreating the crime scene and reviewing it. It Involves proper
documentation of the crime scene along with photographing, sketching, and crime-scene mapping.
Presentation
In this last step, the process of summarization and explanation of conclusions is done.
4. However, it should be written in a layperson’s terms using abstracted terminologies. All abstracted terminologies should reference the
specific details.
Types of Digital Forensics
