Acknowledgement (data networks)

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

Buffer overflow

In information security and programming, a buffer overflow, or buffer overrun, is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory locations.

Byte

The byte is a unit of digital information that most commonly consists of eight bits, representing a binary number.

Chuck Forsberg

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

CP/M

CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc.

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 raw data.

Data structure alignment

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

Error detection and correction

In information theory and coding theory with applications in computer science and telecommunication, error detection and correction or error control are techniques that enable reliable delivery of digital data over unreliable communication channels.

Filename

A filename (also written as two words, file name) is a name used to uniquely identify a computer file stored in a file system.

Kilobyte

The kilobyte is a multiple of the unit byte for digital information.

Microcomputer

A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU).

Modem

A modem (modulator–demodulator) is a network hardware device that modulates one or more carrier wave signals to encode digital information for transmission and demodulates signals to decode the transmitted information.

Serial port

In computing, a serial port is a serial communication interface through which information transfers in or out one bit at a time (in contrast to a parallel port).

New!!: YMODEM and Serial port · See more »

Timestamp

A timestamp is a sequence of characters or encoded information identifying when a certain event occurred, usually giving date and time of day, sometimes accurate to a small fraction of a second.

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.

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.

ZMODEM

ZMODEM is a 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.

16550 UART

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