1, The full form of ARM is Adjustable Rate Mortgage. It’s used on Business ,Banking in Worldwide

A variable-rate mortgage, adjustable-rate mortgage, or tracker mortgage is a mortgage loan with the interest rate on the note periodically adjusted based on an index which reflects the cost to the lender of borrowing on the credit markets. The loan may be offered at the lender’s standard variable rate/base rate.

2, The full form of ARM is Advanced RISC Machine. It’s used on Computing ,Hardware in Worldwide

Advanced RISC Machine (ARM, Originally Acorn RISC Machine) is a series of low-cost, power-efficient 32-bit RISC microprocessors developed by ARM Holdings for embedded control, computing, mobile phones, digital signal processing etc.

ARM (stylised in lowercase as arm, previously an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of reduced instruction set computing (RISC) architectures for computer processors, configured for various environments. Arm Ltd. develops the architecture and licenses it to other companies, who design their own products that implement one of those architectures‍—‌including systems-on-chips (SoC) and systems-on-modules (SoM) that incorporate different components such as memory, interfaces, and radios. It also designs cores that implement this instruction set and licenses these designs to a number of companies that incorporate those core designs into their own products.

3, The full form of ARM is Application Response Measurement. It’s used on Computing ,Sofware & Applications in Worldwide

Application Response Measurement (ARM) is an open standard that describes a common method for integrating enterprise applications as manageable entities. The ARM standard allows users to extend their enterprise management tools directly to applications creating a comprehensive end-to-end management capability that includes measuring application availability, application performance, application usage, and end-to-end transaction response time.

4, The full form of ARM is Association of Railway Museums. It’s used on Associations & Organizations ,Regional Organizations in Worldwide

The Association of Railway Museums (ARM) is an organization dedicated to promoting the interests of railway preservation across North America in museums and other non-profit organizations.

5, The full form of ARM is Atmospheric Radiation Measurement. It’s used on Academic & Science ,Research & Development in United States

The Atmospheric Radiation Measurement (ARM) Climate Research Facility is a U.S. Department of Energy scientific user facility for the study of global climate change by the national and international research community.

ARM is a multi-platform scientific user facility with instruments at fixed and varying locations around the globe for obtaining continuous field measurements of atmospheric data.

The Atmospheric Radiation Measurement (ARM) user facility (www.arm.gov) is a multi-laboratory scientific user facility with the objective of providing a detailed and accurate description of the Earth’s atmosphere in diverse climate regimes to resolve the uncertainties in climate and earth system models. ARM provides the national and international research community with strategically located in situ and remote sensing observatories designed to improve the understanding and representation, in climate and earth system models, of clouds and aerosols as well as their interactions and coupling with the Earth’s surface.

ARM operates a global network of in situ and remote sensing atmospheric observatories in climatically significant locations to sample continental and marine conditions in diverse environments with a goal to improve capabilities of models to make high quality predictions across the globe. There are three fixed sites (U.S. Southern Great Plains, North Slope of Alaska, and the Azores) and three mobile facilities to explore science questions beyond those addressed by ARM’s fixed sites.  ARM also has an aerial measurement capability to complement the ground measurements by providing information on spatial variability as well as detailed information on aerosol and cloud microphysical properties that can be obtained only through in situ measurements. ARM supports the development of scientific data products from ARM observations and hosts a data archive that provides scientists with quality-assured data in near real time. Users may access ARM data free of charge and may propose experiments or field campaigns using the ARM fixed, mobile, and aerial facilities.

6, The full form of ARM is Anti-Radiation Missile. It’s used on Governmental ,Weapons & Forces in Worldwide

An anti-radiation missile (ARM) is a missile designed to detect and home in on an enemy radio emission source. Typically, these are designed for use against an enemy radar, although jammers^[2] and even radios used for communications can also be targeted in this manner.

The earliest known anti radiation missile is a variant of the Blohm & Voss Bv 246 radar guided missile
