We can classify the systems based on stability as follows. Absolutely stable system Conditionally stable system Marginally stable system Absolutely Stable System If the system is stable for all the range of system component values, then it is known as the absolutely stable system. The open loop control system is absolutely stable if all the poles of the open loop transfer function present in left half of āsā plane. Similarly, the closed loop control system is absolutely stable if all the poles of the closed loop transfer function present in the left half of the āsā plane. Conditionally Stable System If the system is stable for a certain range of system component values, then it is known as conditionally stable system. Marginally Stable System If the system is stable by producing an output signal with constant amplitude and constant frequency of oscillations for bounded input, then it is known as marginally stable system. The open loop control system is marginally stable if any two poles of the open loop transfer function is present on the imaginary axis. Similarly, the closed loop control system is marginally stable if any two poles of the closed loop transfer function is present on the imaginary axis.
An operating system (OS) is the software used to run a computer. Windows is an example for a operating system. Apple designed the Mac OS to run more stable.
At lower energy, a system is more stable. At a higher energy, the system will have a tendency to achieve a lower energy. For example, a ball tends to roll down a slope, a compressed (or extended) spring tends to relax.At lower energy, a system is more stable.

Some viruses that are considered stable include hepatitis B virus and HIV. These viruses have stable genetic material (DNA for hepatitis B and RNA for HIV) and can persist in the body for long periods of time without losing their ability to replicate. Additionally, they have evolved mechanisms to escape the host immune response and have efficient ways to infect new cells.
A stable system is one that holds stability and is dependable. An unstable system is just the opposite. You do not know what to expect from an unstable system; it is not close to being dependable.

For example titanium dioxide (TiO2) is a stable and nontoxic compound.

For example, xenon, a noble gas can form stable compounds.
Marginally stable system is when the system control components are JUST right. So if they change slightly the system becomes unstable. I wouldn't fly on that airplain.
