          The American Standard Code for Information Interchange, or ASCII, is a standardized character encoding scheme used widely in computing and electronic devices. It represents and manipulates text, including letters, digits, punctuation, and control characters.<\/p>"},{"question":"When was ASCII first developed and by whom?","answer":"

          ASCII was developed in the 1960s by Robert W. Bemer, who was working at IBM at the time. Recognizing the need for a universal code to standardize the representation of text in computers, Bemer led the development of ASCII, which was first published as a standard by the American National Standards Institute (ANSI) in 1963.<\/p>"},{"question":"What is the difference between Standard ASCII and Extended ASCII?","answer":"

          Standard ASCII is the original 7-bit version that can represent 128 characters, while Extended ASCII is an 8-bit version that doubles the number of representable characters to 256, allowing for the representation of non-English characters and graphical symbols.<\/p>"},{"question":"How does ASCII work?","answer":"

          Each ASCII character is represented by a unique binary number. When a key on a keyboard is pressed, the ASCII value of the corresponding character is sent to the computer's processor. The processor, understanding the binary representation, performs the appropriate action.<\/p>"},{"question":"What are the key features of ASCII?","answer":"

          ASCII's key features include standardization, simplicity, and compatibility. It provides a standard, uniform way of representing text across different platforms and devices. It is straightforward and easy to understand, making it widely applicable in various computing applications. Its 7-bit design makes it compatible with a wide range of hardware and software.<\/p>"},{"question":"What are the limitations of ASCII?","answer":"

          One major limitation of ASCII is its inability to represent characters from non-English languages. This has been addressed through the development of Unicode, a standard that covers virtually all writing systems in the world, while still retaining ASCII's original character set for backward compatibility.<\/p>"},{"question":"How does ASCII relate to proxy servers?","answer":"

          While not directly related to ASCII, proxy servers do process HTTP requests and responses, which are generally written in ASCII. Therefore, a basic understanding of ASCII can be beneficial in understanding and troubleshooting issues that may arise in the communication between a proxy server and a web server.<\/p>"}]},"_links":{"self":[{"href":"https:\/\/oneproxy.pro\/cn\/wp-json\/wp\/v2\/wiki\/475848","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/oneproxy.pro\/cn\/wp-json\/wp\/v2\/wiki"}],"about":[{"href":"https:\/\/oneproxy.pro\/cn\/wp-json\/wp\/v2\/types\/wiki"}],"version-history":[{"count":0,"href":"https:\/\/oneproxy.pro\/cn\/wp-json\/wp\/v2\/wiki\/475848\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/oneproxy.pro\/cn\/wp-json\/wp\/v2\/media\/467532"}],"wp:attachment":[{"href":"https:\/\/oneproxy.pro\/cn\/wp-json\/wp\/v2\/media?parent=475848"}],"curies":[{"name":"\u53ef\u6e7f\u6027\u7c89\u5242","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
