说明JPEG – is a popular graphic format, which is characterized by a high degree of compression, which leads to a decrease in image quality. It uses the technology of encoding of smooth color renditions, providing the ability to reduce the amount of data frequently during the recording of the image.
Because of the small size it is requested by the owners of websites, allowing you to save the traffic effectively. It is also frequently used in memory cards of digital video cameras. The JPEG algorithm is optimally suitable for compressing photographs and pictures, in which realistic scenes with little contrast of colors are present. It is not recommended to use this format for compression of drawings and various kinds of graphics, since a strong contrast between a number of closely located pixels provokes the appearance of visible artifacts.

技术细节The procedure for compressing the digital images in JPEG format is carried out in several stages. First, the photo is transformed into a color space YCbCr, then it is divided into squares to determine the upper range of the color spectrum. Finally, the colors and brightness are coded.
JPEG uses a "lossy" compression system and discrete cosine transform technology. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. The file compression ratio is in the range from 10:1 to 100:1. In this case, the reduction in image quality can vary from insignificant to substantial.

说明HTML - 是与网页相关联的特殊格式，使用适当的标记语言开发。 链接链接的很多页面构成了网站。 具有类似扩展名的文件由文本编辑器修改，因为它们是标准文本文档。 但是，为避免显示不正确，建议使用专用软件，例如Adobe Dreamweaver。 所有现代浏览器都允许您打开HTML文件，但默认情况下不显示源代码。 可以通过选择“查看源”来在Web浏览器菜单中查看它。 类别或使用文本编辑器。
具有HTML扩展名的文件包括文本内容和文本形式的链接到外部对象，例如文章内的图片。

技术细节HTML语言是由T. Berners-Lee创建的，用于在强制领域没有深入知识的人们交换科学和技术信息。 它基于使用包含在尖括号中的多个标签。 现代浏览器通过向用户提供格式化文本来轻松解释HTML4语言。 现在有第五个版本的DOM规范（以前称为SGML）。
