Understanding is a cognitive process related to an abstract or physical object, such as a person, situation, or message whereby one is able to use concepts to model that object.Understanding is a relation between the knower and an object of understanding. Understanding implies abilities and dispositions with respect to an object of knowledge that are sufficient to support intelligent behavior.[1]
Ludwig Wittgenstein looked past a definition of knowledge or understanding and looked at how the words were used in natural language, identifying relevant features in context.[4] It has been suggested that knowledge alone has little value whereas knowing something in context is understanding,[5] which has much higher relative value but it has also been suggested that a state short of knowledge can be termed understanding.[6][7]
Someone's understanding can come from perceived causes [8] or non causal sources,[9] suggesting knowledge being a pillar of where understanding comes from.[10] We can have understanding while lacking corresponding knowledge and have knowledge while lacking the corresponding understanding.[11] Even with knowledge, relevant distinctions or correct conclusion about similar cases may not be made [12][13] suggesting more information about the context would be required, which eludes to different degrees of understanding depending on the context.[10] To understand something implies abilities and dispositions with respect to an object of knowledge that are sufficient to support intelligent behavior.[14]
Understanding could therefore be less demanding than knowledge, because it seems that someone can have understanding of a subject even though they might have been mistaken about that subject. But it is more demanding in that it requires that the internal connections among ones' beliefs actually be "seen" or "grasped" by the person doing the understanding when found at a deeper level.[10]
Explanatory realism and the propositional model suggests understanding comes from causal propositions [15] but, it has been argued that knowing how the cause might bring an effect is understanding.[16] As understanding is not directed towards a discrete proposition, but involves grasping relations of parts to other parts and perhaps the relations of part to wholes.[17] The relationships grasped help understanding, but the relationships are not always causal.[18] So understanding could therefore be expressed by knowledge of dependencies.[16]
This document, "Understanding WCAG 2.0," is an essential guide to understanding and using Web Content Accessibility Guidelines (WCAG) 2.0 [WCAG20]. It is part of a series of documents that support WCAG 2.0. Please note that the contents of this document are informative (they provide guidance), and not normative (they do not set requirements for conforming to WCAG 2.0). See Web Content Accessibility Guidelines (WCAG) Overview for an introduction to WCAG, supporting technical documents, and educational material.
WCAG 2.0 establishes a set of Success Criteria to define conformance to the WCAG 2.0 Guidelines. A Success Criterion is a testable statement that will be either true or false when applied to specific Web content. "Understanding WCAG 2.0" provides detailed information about each Success Criterion, including its intent, the key terms that are used in the Success Criterion, and how the Success Criteria in WCAG 2.0 help people with different types of disabilities. This document also provides examples of Web content that meet the success criterion using various Web technologies (for instance, HTML, CSS, XML), and common examples of Web content that does not meet the success criterion.
This document indicates specific techniques to meet each Success Criterion. Details for how to implement each technique are available in Techniques for WCAG 2.0, but "Understanding WCAG 2.0" provides the information about the relationship of each technique to the Success Criteria. Techniques are categorized by the level of support they provide for the Success Criteria. "Sufficient techniques" are sufficient to meet a particular Success Criterion (either by themselves or in combination with other techniques), while other techniques are advisory and therefore optional. None of the techniques are required to meet WCAG 2.0, although some may be the only known method if a particular technology is used. "Advisory techniques" are not sufficient to meet the Success Criteria on their own (because they are not testable or provide incomplete support) but it is encouraged that authors follow them when possible to provide enhanced accessibility.
In addition to techniques for addressing the success criteria, "Common Failures" are also documented. These "Common Failures" are authoring practices that are known to cause Web content to fail to conform to WCAG 2.0. Authors must avoid those practices in order to meet the WCAG 2.0 Success Criteria.
This document is part of a series of documents published by the W3C Web Accessibility Initiative (WAI) to support WCAG 2.0. This document was published as a Working Group Note at the same time WCAG 2.0 was published as a W3C Recommendation. Unlike WCAG 2.0, is expected that the information in Understanding WCAG 2.0 will be updated from time to time. See Web Content Accessibility Guidelines (WCAG) Overview for an introduction to WCAG, supporting technical documents, and educational material.

Power Africa has developed a series of handbooks to establish a common understanding of best practices around successful power project development. The Understanding series now includes a total of four handbooks, with 55,000 copies in print and tens of thousands more copies downloaded online.
The Understanding series was developed as part of the Power Africa Initiative and the development of these handbooks is funded by USAID. The handbooks in the Understanding series are intended to serve as practical resources for decision-makers on the policy and strategy behind the development, financing, and procurement of power projects. CLDP facilitates the drafting and publishing of these books with its key partner, the African Legal Support Facility (ALFS). Each of the handbooks have been developed using the Book Sprint method which allows a diverse group of contributors from African governments, multilateral institutions, development banks, private developers, procurement consultants and leading international law firms, all whom contribute their time on a pro-bono basis, to complete the handbooks in a quick and efficient manner. Each of the handbooks has been published under the Creative Commons License.
Energy Storage technology plays a critical role in enabling energy transition and increasing energy access. The Understanding Energy Storage handbook is intended to serve as a resource for decision-makers in the power space across sub-Saharan Africa to demystify energy storage technology and regulations.
The critical nature of transmission infrastructure to the overall function of an energy market cannot be overstated. As generation expands, transmission is needed to bring electricity to the demand centers.
The power purchase agreement (PPA) is the central contract for any independent power generation project, especially in emerging markets. This handbook explains the context for the PPA and sets out the key considerations for drafting and negotiating the PPA.
Procuring power projects is complex and there are a variety of approaches the public party can use to establish and maintain power projects. This handbook provides an overview of the mechanisms and strategy behind successful Power Project Procurement, including the advantages and disadvantages of the alternatives.
Financing is a key aspect of developing any power project. This handbook provides an overview of the different financing alternatives for power transactions and the advantages and disadvantages of each.
