Microsoft MCITP Certifications Exam 70-647

The logical layer sits on top of the infrastructure layer. Sometimes called the “code”layer, it consists of the 70-620 software programs and protocols that“drive” the infrastructure, and that provide an interface to the user. At this layer, too, there exist various ways in which governance can address problems, enhance existing processes, and help to ensure that the Internet achieves its full potential.

Standards
Standards are among the most important issues addressed by Internet governance at any layer. As noted, the Internet 70-640 is only able to function seamlessly over different networks, operating systems, browsers and devices because it sits on a bedrock of commonly agreed-upon technical standards. TCP/IP, discussed earlier, is perhaps the most important of these standards. Two other key standards are the HyperText Mark-up Language (HTML) and the HyperText Transfer Protocol (HTTP), developed by Tim Berners-Lee and his colleagues at CERN in Geneva to standardize the presentation and transport of web pages. Much as TCP/IP is the basis for the growth of the Internet’s infrastructure, so HTTP and HTML are the 70-647 basis for the phenomenal growth of the World Wide Web. Other critical standards include Extensible Mark-up Language (XML), a standard for presenting information on web pages, and IPv6 (Internet Protocol, version 6, the successor to the current IPv4), used in Internet-addressing systems (see discussion below).
