** ISO 3166-1 alpha-2 – two-letter country codes which are the most widely used of the three, and used most prominently for the Internet's country code top-level domains ( with a few exceptions ).

** ISO 3166-1 alpha-3 – three-letter country codes which allow a better visual association between the codes and the country names than the alpha-2 codes.

** ISO 3166-1 numeric – three-digit country codes which are identical to those developed and maintained by the United Nations Statistics Division, with the advantage of script ( writing system ) independence, and hence useful for people or systems using non-Latin scripts.

** 7bit – up to 998 octets per line of the code range 1 .. 127 with CR and LF ( codes 13 and 10 respectively ) only allowed to appear as part of a CRLF line ending.

** 8bit – up to 998 octets per line with CR and LF ( codes 13 and 10 respectively ) only allowed to appear as part of a CRLF line ending.

** add, subtract, multiply, or divide the values of two registers, placing the result in a register, possibly setting one or more condition codes in a status register

** SDLC included much more powerful error detection and correction codes than earlier protocols.

** It enabled terminals and 3705 communications processors to send " frames " of data one after the other without waiting for an acknowledgement of the previous frame-the communications cards had sufficient memory and processing capacity to " remember " the last 7 frames sent or received, request re-transmission of only those frames which contained errors that the error detection and correction codes could not repair, and slot the re-transmitted frames into the right place in the sequence before forwarding them to the next stage.
