Hi Fi Protection

Protection is any measure taken to guard something against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring:The meaning of the word protection, as used in the electrical industry, is no different to that in everyday use. People protect themselves against personal or financial loss by means of insurance as well as from injury or discomfort by the use of protective clothing. They further protect their property by the installation of security measures such as locks and/or alarm systems.
