Glossary - O
This is a glossary of older terms. While many of the definitions are unchanged, some of the definitions may be out of date and some of the terms may no longer be in use in the Data Center industry. This legacy glossary provides definitions for hundreds of information and communications technology (ICT) and data center terms and acronyms. Arranged alphabetically and searchable, the glossary explains common industry vocabulary.

Operating pressure
Maximum internal fluid pressure recommended for safe, reliable operation. Special consideration for extreme temperature applications, or when in combination with high flow rates. An operating pressure of 0-120 psi (0 to 827.4 kPa) may be considered for water-cooling applications. Source: ASHRAE
Operating System
Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices, such as disk drives and printers. It ensures that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, run
