Digital forensics (sometimes known as digital forensic science) is a branch of forensic science encompassing the recovery and investigation of material found in digital devices, often in relation to computer crime.

The term digital forensics was originally used as a synonym for computer forensics but has expanded to cover investigation of all devices capable of storing digital data.

With roots in the personal computing revolution of the late 1970s and early 1980s, the discipline evolved in a haphazard manner during the 1990s, and it was not until the early 21st century that national policies emerged.

Computer security, also known as cybersecurity or IT security, is the protection of computer systems from the theft or damage to the hardware, software or the information on them, as well as from disruption or misdirection of the services they provide.

Linux (pronounced or, less frequently) is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution.

The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds.

The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy.

Parrot is a register-based process virtual machine designed to run dynamic languages efficiently.

It is possible to compile Parrot assembly language and PIR (an intermediate language) to Parrot bytecode and execute it.

Parrot is free and open source software.

Privacy is the ability of an individual or group to seclude themselves, or information about themselves, and thereby express themselves selectively.

The boundaries and content of what is considered private differ among cultures and individuals, but share common themes.

When something is private to a person, it usually means that something is inherently special or sensitive to them.

The domain of privacy partially overlaps security (confidentiality), which can include the concepts of appropriate use, as well as protection of information.

Privacy may also take the form of bodily integrity.
