'''Dew computing''' is an [[information technology]] ([[Information technology|IT]]) paradigm that combines the core concept of [[cloud computing]] with the capabilities of end devices ([[personal computer]]s, [[mobile phone]]s, etc.).<ref>{{Cite journal|last=Wang|first=Yingwei|date=2015-09-16|title=Cloud-dew architecture|url=http://www.inderscience.com/offer.php?id=71717|journal=International Journal of Cloud Computing (IJCC)|volume=4(|issue=3)|pages=199–210|via=|doi=10.1504/IJCC.2015.071717}}</ref> It is used to enhance the experience for the end user in comparison to only using [[cloud computing]].<ref name=":2">{{Cite book|date=2018|editor-last=Hu|editor-first=Yu-Chen|editor2-last=Tiwari|editor2-first=Shailesh|editor3-last=Mishra|editor3-first=Krishn K.|editor4-last=Trivedi|editor4-first=Munesh C.|title=Intelligent Communication and Computational Technologies|volume=19|doi=10.1007/978-981-10-5523-2|issn=2367-3370|series=Lecture Notes in Networks and Systems|isbn=978-981-10-5522-5}}</ref> Dew computing attempts to solve major problems related to cloud computing technology, such as reliance on [[internet access]].

This allows the user to access files during times without an internet connection; when a connection is established again, files and folders are synchronized back to the cloud server.<ref name=":0">{{Cite journal|last=Wang|first=Yingwei|date=2016|title=Definition and Categorization of Dew Computing|url=https://www.ronpub.com/publications/ojcc/OJCC_2016v3i1n02_YingweiWang.html|journal=Open Journal of Cloud Computing|volume=3|issue=1|issn=2199-1987}}</ref>

Line 8:

Dew computing is a model which was derived from the original concept of [[cloud computing]]. Other models have also emerged from cloud computing, including [[fog computing]], [[edge computing]], dew computing, and others. Proponents claim that these novel models, such as dew computing, can provide better experiences for users.<ref name=":5">{{Cite web|url=https://www.semanticscholar.org/paper/Doing-More-with-the-Dew:-A-New-Approach-to-Fisher-Yang/693e467a3b5efd3ae578687fa7af3e5e57deca00|title=Doing More with the Dew: A New Approach to Cloud-Dew Architecture - Semantic Scholar|access-date=2018-06-30}}</ref>

Cloud computing provides universal access and [[scalability]]. However, having all the resources far from a user's control occasionally causes problems. In the classic cloud computing paradigm, when the internet connection to the [[Server (computing)|servers]] is lost, the user is unable to access their data; dew computing aims to solve this problem.<ref name=":0" /><ref name=":6">{{Cite web|url=https://www.semanticscholar.org/paper/Cloud-dew-architecture-:-realizing-the-potential-of-Wang-Pan/fc8edd29f5df60244a66d05c74c50a240a4529ef|title=Cloud-dew architecture : realizing the potential of distributed database systems in unreliable networks - Semantic Scholar|access-date=2018-06-30}}</ref><ref name=":1">{{Cite news|url=https://phys.org/news/2015-09-dew-ground-cloud.html|title=Dew helps ground cloud computing|access-date=2018-06-30}}</ref><ref name=":4">{{Cite journal|last=Yingwei|first=Wang,|date=2015|title=The initial definition of dew computing|url=https://www.islandscholar.ca/islandora/object/ir:20044|journal=Dew Computing Research}}</ref>

== Possible challenges ==

Dew computing faces a number of technical challenges, including issues related to power management, processor utility, and data storage. Other factors impacting the use of dew computing are the viability of the operation system, network model, and communication model, programming principles, dew recommended engine, local dew network, personal high productivity, database security, and behaviors of the browser.<ref name=":3">{{Cite web|url=https://ieeexplore.ieee.org/document/8114187/journal|title=An Introduction to Dew Computing: Definition, Concept and Implications - IEEE Journals & Magazine|websitejournal=ieeexploreIEEE Access|volume=6|pages=723–737|doi=10.ieee1109/ACCESS.org2017.2775042|access-dateyear=2018-06-30|last1=Ray|first1=Partha Pratim}}</ref>
