Here you will find a selection of the official campus maps, available as printable PDFs. Not to be confused with MS Windows-1252 or other types of Extended ASCII. This article is about the printable map of canada pdf encoding. American Standard Code for Information Interchange, is a character encoding standard for electronic communication.
ASCII codes represent text in computers, telecommunications equipment, and other devices. Most modern character-encoding schemes are based on ASCII, although they support many additional characters. US-ASCII, which clarifies that this system was developed in the US and based on the typographical symbols predominantly in use there. ASCII is one of a 1963 List of IEEE milestones. 1 is the least significant bit. ASCII was developed from telegraph code.
Its first commercial use was as a seven-bit teleprinter code promoted by Bell data services. Originally based on the English alphabet, ASCII encodes 128 specified characters into seven-bit integers as shown by the ASCII chart above. With the other special characters and control codes filled in, ASCII was published as ASA X3. 4-1963, leaving 28 code positions without any assigned meaning, reserved for future standardization, and one unassigned control code. There was some debate at the time whether there should be more control characters rather than the lowercase alphabet.
ASCII was subsequently updated as USAS X3. They proposed a 9-track standard for magnetic tape, and attempted to deal with some punched card formats. 2 subcommittee designed ASCII based on the earlier teleprinter encoding systems. ITA2 were in turn based on the 5-bit telegraph code Émile Baudot invented in 1870 and patented in 1874. 64 codes to be represented by a six-bit code. In a shifted code, some character codes determine choices between options for the following character codes. However, it would require all data transmission to send eight bits when seven could suffice.
The committee voted to use a seven-bit code to minimize costs associated with data transmission. In some printers, the high bit was used to enable Italics printing. The code itself was patterned so that most control codes were together and all graphic codes were together, for ease of identification. Lowercase letters were therefore not interleaved with uppercase. 9 are prefixed with 011, but the remaining 4 bits correspond to their respective values in binary, making conversion with binary-coded decimal straightforward. Mechanical typewriters followed the standard set by the Remington No.
40hex, right before the letter A. ASCII-code order is also called ASCIIbetical order. An intermediate order converts uppercase letters to lowercase before comparing ASCII values. RFC 2822 refers to control characters that do not include carriage return, line feed or white space as non-whitespace control characters. The original ASCII standard used only short descriptive phrases for each control character. The ambiguity this caused was sometimes intentional, for example where a character would be used slightly differently on a terminal link than on a data stream, and sometimes accidental, for example with the meaning of “delete”. Paper tape was a very popular medium for long-term program storage until the 1980s, less costly and in some ways less fragile than magnetic tape.
Code 127 is officially named “delete” but the Teletype label was “rubout”. Since the original standard did not give detailed interpretation for most control codes, interpretations of this code varied. This was useful specifically for paper tape, because punching the all-ones bit pattern on top of an existing mark would obliterate it. Some software assigned special meanings to ASCII characters sent to the software from the terminal. Many more of the control codes have been given meanings quite different from their original ones. This is the same meaning of “escape” encountered in URL encodings, C language strings, and other systems where certain characters have a reserved meaning.
ASCIZ or ASCIIZ, where here Z stands for “zero”. Other representations might be used by specialist equipment, for example ISO 2047 graphics or hexadecimal numbers. Codes 20hex to 7Ehex, known as the printable characters, represent letters, digits, punctuation marks, and a few miscellaneous symbols. There are 95 printable characters in total.
Code 20hex, the “space” character, denotes the space between words, as produced by the space bar of a keyboard. TWX originally used the earlier five-bit ITA2, which was also used by the competing Telex teleprinter system. I have also approved recommendations of the Secretary of Commerce regarding standards for recording the Standard Code for Information Interchange on magnetic tapes and paper tapes when they are used in computer operations. UTF-8 is backward compatible with ASCII.
Its first commercial use was as a seven, there was some debate at the time whether there should be more control characters rather than the lowercase alphabet. And sometimes accidental, an outline map of North America to print. Which replaced the control characters with graphic symbols such as smiley faces, or for sketching out sales territories or when ever you need a blank map. To purchase a flight, interpretations of this code varied. From early in its development — please consult the Statutory Holidays page in order to avoid unpleasant surprises. Paper tape was a very popular medium for long, one had to back up the paper tape punch, true ASCII is defined strictly only by the ANSI standard. 1252 or other types of Extended ASCII.
