Acknowledgement (data networks)

In data networking, telecommunications, and computer buses, an acknowledgement (ACK) is a signal that is passed between communicating processes, computers, or devices to signify acknowledgment, or receipt of message, as part of a communications protocol.

See YMODEM and Acknowledgement (data networks)

Buffer overflow

In programming and information security, a buffer overflow or buffer overrun is an anomaly whereby a program writes data to a buffer beyond the buffer's allocated memory, overwriting adjacent memory locations.

See YMODEM and Buffer overflow

Bulletin board system

A bulletin board system (BBS), also called a computer bulletin board service (CBBS), was a computer server running software that allowed users to connect to the system using a terminal program.

See YMODEM and Bulletin board system

Checksum

A checksum is a small-sized block of data derived from another block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage.

See YMODEM and Checksum

Chuck Forsberg

Charles Alton "Chuck" Forsberg (May 6, 1944 – September 24, 2015) developed two data transmission protocols popular in the 1990s, for uploading and downloading files from dial-up bulletin board systems.

Comparison of file transfer protocols

This article lists communication protocols that are designed for file transfer over a telecommunications network.

See YMODEM and Comparison of file transfer protocols

CP/M

CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk.

See YMODEM and CP/M

Cyclic redundancy check

A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data.

See YMODEM and Cyclic redundancy check

Data structure alignment

Data structure alignment is the way data is arranged and accessed in computer memory.

See YMODEM and Data structure alignment

FidoNet

FidoNet logo by John Madill FidoNet is a worldwide computer network that is used for communication between bulletin board systems (BBSes).

See YMODEM and FidoNet

File transfer

File transfer is the transmission of a computer file through a communication channel from one computer system to another.

See YMODEM and File transfer

Latency (engineering)

Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed.

See YMODEM and Latency (engineering)

Microcom Networking Protocol

The Microcom Networking Protocols, almost always shortened to MNP, is a family of error-correcting protocols commonly used on early high-speed (2400 bit/s and higher) modems.

See YMODEM and Microcom Networking Protocol

Microcomputer

A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor.

See YMODEM and Microcomputer

Modem

A modulator-demodulator or most commonly referred to as modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio.

See YMODEM and Modem

Network packet

In telecommunications and computer networking, a network packet is a formatted unit of data carried by a packet-switched network.

See YMODEM and Network packet

Serial port

A serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time.

See YMODEM and Serial port

Sliding window protocol

A sliding window protocol is a feature of packet-based data transmission protocols.

See YMODEM and Sliding window protocol

Ward Christensen

Ward Christensen (born 1945 in West Bend, Wisconsin, United States) is the co-founder of the CBBS bulletin board, the first bulletin board system (BBS) ever brought online.

See YMODEM and Ward Christensen

XMODEM

XMODEM is a simple file transfer protocol developed as a quick hack by Ward Christensen for use in his 1977 MODEM.ASM terminal program. YMODEM and XMODEM are BBS file transfer protocols.

See YMODEM and XMODEM

ZMODEM

ZMODEM is an inline file transfer protocol developed by Chuck Forsberg in 1986, in a project funded by Telenet in order to improve file transfers on their X.25 network. YMODEM and ZMODEM are BBS file transfer protocols.

See YMODEM and ZMODEM

16550 UART

The 16550 UART (universal asynchronous receiver-transmitter) is an integrated circuit designed for implementing the interface for serial communications.

See YMODEM and 16550 UART
