=1.10 Standards and Protocols=

//**__ITGS Guide:__**// Standards and protocols are technical rules and conventions that enable compatibility and therefore facilitate communication or interoperability between different IT systems and their components. They might govern the design and use of hardware, software and information. For example, the communication protocols used on the internet, the ASCII representations for characters, or the design of the printer port on a personal computer are all governed by standards.

__**Standards and Protocols:**__
Technical standards are instituted for compatibility and interoperability between software, systems, platforms and devices. Protocols are a system of digital message formats and rules for exchanging those messages in or between computing systems and in telecommunications. media type="youtube" key="HnYmnQ7g-fw" height="224" width="293"

Here is a list of various different standards: http://en.wikipedia.org/wiki/List_of_computer_standards

Examples of well known Standard & Protocols include:
 * ASCII (American Standard Code for Information Interchange),
 * HTTP (Hyper-Text Transfer Protocol),
 * IP (Internet Protocol),
 * Unicode
 * UTF-8

=**ASCII**=

The American Standard Code for Information Interchange is a character-encoding scheme based on the ordering of the English alphabet. It was developed from telegraphic codes and was initially used as a seven-bit teleprinter code. ASCII includes definitions for 128 characters: 33 are non-printing control characters that affect how text and space is processed; 95 are printable characters, including the space which is considered an invisible graphic. The most commonly used character encoding on the World Wide Web was US-ASCII until December 2007, when it was surpassed by UTF-8.
