ANSI —— (1) ANSI is an organization that sets standards. (2) 'ANSI graphics' (ref. the term ANSI-BBS) is a set of cursor control codes that originated on the VT100 terminal. Many online services use these codes to help improve the sending of characters to communication programs. It uses the escape character, followed by other characters, to move the cursor on the screen, change color, and more.
Archie ——— An electronic directory service for locating information throughout the Internet. You can use Archie to locate files on anonymous ftp archive sites, other online directories and resource listings. It is useful for finding free software. Archie offers access to the "whatis" description database. This database contains descriptions that include the name and a brief synopsis of the large number of public domain software, datasets and informational documents located on the Internet. This book emphasizes email access to Archie. You can also reach archie servers by telnet to one of the following addresses:

An email-based file transfer facility offered by some systems
connected to the Internet.
ASCII ——- The American Standard Code for Information Interchange. A standard seven-bit code created to achieve compatibility between various types of data processing equipment. ASCII, pronounced "ask-key," is the common code for microcomputer equipment. The Standard ASCII Character Set consists of 128 decimal numbers ranging from zero through 127 assigned to letters, numbers, punctuation marks, and the most common special characters. The Extended ASCII Character Set also consists of 128 decimal numbers and ranges from 128 through 255 representing additional special, mathematical, graphic, and foreign characters.
ASCII download ——————— Retrieval of plain ASCII text (without special codes). Normally, it takes place without automatic error correction, but it is typically managed by XON/XOFF flow control.
Asynchronous transfer ——————————- Serial communication between two computers. When signals are sent to a computer at irregular intervals, they are described as asynchronous. Data is sent at irregular intervals by preceding each character with a start bit and following it with a stop bit. Asynchronous transmission allows a character to be sent at random after the preceding character has been sent, without regard to any timing device. Consequently, in case of line noise, the modem can find out right away where the next byte should start.
Autodial ———— When a modem dials a telephone number automatically. Autodial may be started by the user entering the number manually, or the number may be sent automatically by the communications program (for example after having been selected from a phone register).
Baud —— A unit of measurement that shows the number of discrete signal elements, such as bits, that can be sent per second. Bits per second (bps) is the number of binary digits sent in one second. There is a difference between bps and baud rate, and the two are often confused. For example, a device such as a modem said to send at 2400 baud is not correct. It actually sends 2400 bits per second. Both baud rate and bps refer to the rate at which the bits within a single frame are sent. The gaps between the frames can be of variable length. Accordingly, neither baud rate nor bps refer accurately to the rate at which information is actually being transferred.
BBS —- Bulletin Board or Bulletin Board System. See Bulletin Board.
