*'''Hypervisors''' usually used for partitioning physical hardware resources among multiple guest operating systems

*'''Simulators''' where developers build virtual replicas of specific environments or processes

*'''Emulation''' endeavors to recreate an entire historical architecture. This digital reconstruction seeks to faithfully capture the instruction set, timing behaviors, hardware features and even peripheral nuances of a bygone hardware platform. Unlike compatibility layers, which translate software instructions to a native format, emulation builds a virtual stage upon which the software itself can perform authentically. Emulation's intricate tapestry sometimes intertwines with threads of other technologies though. Notably, certain emulators leverage hypervisors for a more efficient handling of resource allocation and isolation. Additionally, some emulators employ compatibility layers as subcomponents, acting as translators for specific libraries or APIs that might otherwise be incompatible with the host environment. Think of these layers as linguistic bridges, allowing the emulated software to converse fluently with the modern system hardware.

*'''Sandboxing''' creates a restricted environment for running applications on your Host operating system. Within this "sandbox," applications can't make permanent changes to your system files or registry.

*'''Docker''' is a containerization platform. It creates isolated containers that share the host operating system kernel but have their own set of files and configurations. Docker is primarily used for deploying and isolating applications, particularly microservices, for development, testing, and deployment purposes.
