:[[Domain Name System|DNS]] stands for [[Domain Name System]]; it describes a system of [[hostname]]s, [[subdomain]]s, etc. In the [[World Wide Web]], [[CNMCyber]] is presented by the [[CNMCyber.com]] [[hostname]].

:*'''[[Mobile app]]''' ([[mobile application]] or, simply, an [[app]]) is an [[end-user application]] that is designed to run on a [[mobile device]]. ''Mobile apps'' often stand in contrast to [[web application]]s which run in [[mobile web browser]]s rather than directly on the ''mobile device''. ''Mobile apps'' often refer those applications as [[web version]]s.
 
−
:*'''[[World Wide Web]]''' ([[WWW]], [[www]]). The part of the [[Internet]] that contains inter-linked hypertext documents, especially [[webpage]]s, and web applications. The web resources are identified by [[Uniform Resource Locator]]s ([[URL]]s) and accessible via the [[web browser]]s. The other parts of the [[Internet]] include [[email]], [[VoIP]] telephony, and file exchange.</div>
 
  
−
:'''[[Web browser]]'''. Any [[end-user application]] that allows for browsing [[web document]]s published at the [[World Wide Web]]. To request the ''Browser'' display some [[website]], a user enters into the ''Browser'' the ''website's'' [[hostname]]. Then, the ''Browser'' utilizes [[DNS]] to locate the sought ''website'' in the [[World Wide Web]] and to get its [[landing page]]'s [[web document]] in order to display this ''webpage'' in the ''Browser''.<div style="background-color:#efefef; padding: 5px; margin: 15px;">
+
:[[Hostname]]s, which are also called [[domain name]]s, are created as human-friendly locators of [[website]]s in the [[World Wide Web]]. When you type any ''domain name'' in the [[web browser]] to request some [[website]], the ''browser'' requests [[DNS server]]s to locate the [[IP address]] of that ''website''. ''IP adresses'' or ''Internet protocol addresses'' consist of numbers and symbols. They are inconvenient for human [[end-user]]s, but the only way for the [[technology]] to locate the resource you look for. [[DNS]] emerged to allow [[human being]]s to bypass [[IP address]]es.
−
:*'''[[URL]]'''. The acronym for [[Uniform Resource Locator]]. A reference to a [[web resource]] that specifies its location on a computer network and a mechanism for retrieving it. ''URLs'' consist of two mandatory fields, (a) type of ''resource'' such as <code>https</code> for [[webpage]]s, <code>ftps</code> for file transfers, <code>mailto</code> for emails, etc., and (b) [[hostname]], as well as of optional (c) one or more [[submomain]]s and (d) a [[file name]], if any.

:*'''[[Web search engine]]''' ([[Internet search engine]]). A [[software system]] that is designed to search the [[World Wide Web]] for particular information specified in a textual web search query.</div>

:'''[[DNS]]'''. The acronym for [[Domain Name System]]. Originally created for name mapping, ''DNS'' today also defines technical settings for its core mapping service.

CNMCyber suites

DNS of CNM Cloud (hereinafter, the Lectio) is the lesson part of the Cloud on the Web lesson that introduces its participants to Opplet. This lesson belongs to the Introduction to CNM Cloud session of EmployableU Concepts.


Content

The predecessor lectio is CNM Cloud Websites.

Script

DNS stands for Domain Name System; it describes a system of hostnames, subdomains, etc. In the World Wide Web, CNMCyber is presented by the CNMCyber.com hostname.
Hostnames, which are also called domain names, are created as human-friendly locators of websites in the World Wide Web. When you type any domain name in the web browser to request some website, the browser requests DNS servers to locate the IP address of that website. IP adresses or Internet protocol addresses consist of numbers and symbols. They are inconvenient for human end-users, but the only way for the technology to locate the resource you look for. DNS emerged to allow human beings to bypass IP addresses.
IP address is different from web address, which is technically called URL or Uniform Resource Locator. URL consists of the protocol name such as in https://, subdomains, hostname, and the path. You can find URL in the address bar of your web browser.
Various systems of CNMCyber are available at subdomains such as cabin.cnmcyber.com for CNM Cabin, cert.cnmcyber.com for CNM Cert, social.cnmcyber.com for CNMCyber.com, tube.cnmcyber.com for CNM Tube, or wiki.cnmcyber.com for CNM Wiki.
The CNM Next Apps, which are those versions of CNM apps that are installed on the CNM Lab Farm, feature the .next. field added to their hostnames such as cert.next.cnmcyber.com and social.next.cnmcyber.com.
Similarly, the CNM HandsOn Apps, which are those versions of CNM apps that are installed on the CNM HandsOn Farm, feature the .handson. field added to their hostnames such as tube.handson.cnmcyber.com and wiki.handson.cnmcyber.com.
To display any webpage, one needs to type its URL into the address bar of web browser. The bar is always located on the top of the page. It is often confused with an input field of web search engine. If you cannot locate the bar, most likely, you use a mobile app.
Similarly to whole CNMCyber, its DNS is a living endeavor as well.

Key terms

DNS, hostname (domain name), subdomain (local hostname), IP address, Uniform Resource Locator (URL, web address)

Closing

Are you familiar with the concept of DNS? --Yes/No/I'm not sure

CNM Cloud SSO is the successor lectio.
