'''Native''' describes a computing system as operating directly with an underlying technology; with no intervening communication or translation layers.
'''Native''' software is [[software build|built]] to be [[Execution (computing)|executed]] directly by [[Processor (computing)|processors]] that implement a compatible [[instruction set]].<ref>{{Cite web|url=https://searchapparchitecture.techtarget.com/definition/native-code|title=What is native code? - Definition from WhatIs.com|website=SearchAppArchitecture|language=en|access-date=2019-11-22}}</ref>
 
== Native software ==
A program that runs natively on one platform is runnable on another platform via an [[emulator]] if an emulator is available and, generally, with significant runtime speed degradation.<ref>{{Cite web|url=https://www.makeuseof.com/tag/how-does-emulation-work/|title=How Does Emulation Work and Why Is It So S

[[Cross-platform software]] can run on multiple processors although possibly requiring it to be re-built for different target systems.
 
== ApplicationNative API ==
A native [[application software|applicationprogramming interface]] uses(API) provides thedirect minimalaccess numberto ofan softwareunderlying layerstechnology. For example, the [[Windows]] [[Native API]] is an [[application programming interface]] specific for the [[Windows NT]] kernel, which provides access to some kernel functions which cannot be directly accessed through the more universal [[Windows API]].
 
== OperatingNative systemVM ==
A native [[operatingvirtual systemmachine]] implies(VM) theruns absencedirectly ofon hardware; without virtualization or virtualization at its lowest level. For example, with multiple levels of virtualization, the lowest level operating system {{endash}} the one that actually maintains direct control of the hardware {{endash}} is referred to as a "Native VM".
 
== Machine code ==
{{expand section|date=February 2012}}
[[Machine code]], also known as native code, is a program which is written in machine language. Machine code is usually considered the lowest level of code for a computer, that, in its lowest level form, is written in binary (0s and 1s), but is often written in [[hexadecimal]] or [[octal]] to make it a little easier to handle.<ref>{{Cite web|url=https://marketbusinessnews.com/financial-glossary/machine-code/|title=What is machine code? Definition and examples|website=Market Business News|language=en-US|access-date=2019-11-23}}</ref> These [[Instruction Sets|instruction sets]] are then interpreted by the computer. With this, there is no need for translation. machine code is strictly numerical and usually isn't what programmers program in, due to this complex nature.<ref>{{Cite web|url=https://marketbusinessnews.com/financial-glossary/machine-code/|title=What is machine code? Definition and examples|website=Market Business News|language=en-US|access-date=2019-11-23}}</ref> Machine code is also as close as you can get to the [[Processor (computing)|processor]], so using this language, you are programming specifically for that processor as machine code for each processor may differ.<ref>{{Cite web|url=https://www.webopedia.com/TERM/M/machine_language.html|title=What is Machine Language?

Since each [[Central processing unit|CPU]] is different, programs need to be recompiled or rewritten in order to work on that CPU.<ref>{{Cite book|url=https://books.google.com/books?id=b5x_NHo5g2oC&q=Programs+must+be+rewritten+or+recompiled%2C+therefore%2C+to+run+on+different+types+of+computers.&pg=PA365|title=Information Technology in Business|last=Manzoor|first=Amir|date=2012-03-19|publisher=Amir Manzoor|isbn=978-1-4699-9188-7|language=en}}</ref>
 
== DataNative data ==
{{expand section|date=February 2012}}
Applied to [[data (computing)|data]], native [[data type|data formats]] or [[communication protocol]]s are those supported by a certain [[computer hardware]] or software, with maximal consistency and minimal amount of additional components.
Line 25 ⟶ 23:
For example, [[Enhanced Graphics Adapter|EGA]] and [[VGA]] video adapters ''natively'' support [[code page 437]]. This does not preclude supporting other [[code page]]s, but it requires either a [[VGA-compatible text mode#Fonts|font uploading]] or using [[All Points Addressable|graphic modes]].
 
== Cloud computingNative ==
In cloud computing, "cloud'''Cloud native"''' refers to the software approach of building, deploying, and managing modern applications in cloud computing environments, {{endash}} for software optimisedoptimized for running on a cloud-based platform. A cloud native application typically consists of individual modular microservices.
