Data transmission

system for exchanging messages between computing systems

computer network that connects devices across a large distance and area

Digitization is the process of converting information into a digital format, i.e., a format that can be read by computers. The result is the representation of an object, image, sound, document, or signal (usually an analog signal) obtained by generating a series of numbers that describe a discrete set of points or samples. The result of this conversion is called digital representation or, more specifically, a digital image for

In computer networks, download means to receive data from a remote system, typically a server such as a web server, an FTP server, an email server, or other similar systems. This contrasts with uploading, where data is sent to a remote system. A download is a file offered for downloading or that has been downloaded, or the process of receiving such a file.

transfer of data over a point-to-point or point-to-multipoint communication channel

In telecommunications and electronics, baud (; symbol: Bd) is a common unit of measurement of symbol rate, which is one of the components that determine the speed of communication over a data channel.

information transmission rate expressed in bits per second

bit added to a binary string to ensure that the sum of the bit values is even or odd; used as an error detecting code

Uploading refers to transmitting data from one computer system to another through means of a network. Common methods of uploading include: uploading via web browsers, FTP clients, and terminals (SCP/SFTP). Uploading can be used in the context of (potentially many) clients that send files to a central server. While uploading can also be defined in the context of sending files between distributed clients, such as with a peer-to-peer (P2P) file-sharing protocol like BitTorrent, the term file sharing is more often used in this case. Moving files within a computer system, as opposed to over a netwo

Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. UWB has traditional applications in non-cooperative radar imaging. Most recent applications target sensor data collection, precise locating, and tracking. UWB support first appeared in high-end smartphones in 2019. For a detailed list of Ultra-wideband supported mobile devices, see List of UWB-enabled mobile devices.

method of transmitting multiple bits of data simultaneously

the ratio between the number of incorrect bits transmitted to the total number of bits

computer program dedicated to downloading (and sometimes uploading) files

supplemental data placed at the beginning of a block of data being stored or transmitted

method of designing modular communication protocols in which separate functions are abstracted from their underlying structures

telecommunications connection for transmission of digital information

MQTT is a lightweight, publish–subscribe, machine-to-machine network protocol for message queue/message queuing service. It is designed for connections with remote locations that have devices with resource constraints or limited network bandwidth, such as in the Internet of things (IoT). It must run over a transport protocol that provides ordered, lossless, bi-directional connections—typically, TCP/IP. It is an open OASIS standard and an ISO recommendation (ISO/IEC 20922).

Input/output operations per second (IOPS, pronounced eye-ops) is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN). Like benchmarks, IOPS numbers published by storage device manufacturers do not directly relate to real-world application performance.

A bitstream (or bit stream), also known as binary sequence, is a sequence of bits.

type of error-detection protocol at the data link layer, and transport layer for TCP

rate of modulation of a digital signal

limits the transfer of a specified amount of data over a period of time

an element of a standardized code or protocol

term describing a multimedia stream or file that contains a constant amount of information per unit time

A Software-Defined Wide Area Network (SD-WAN) is a wide area network that uses software-defined networking technology, such as communicating over the Internet using overlay tunnels which are encrypted when destined for internal organization locations.

A scancode (or scan code) is the data that most computer keyboards send to a computer to report which keys have been pressed. A number, or sequence of numbers, is assigned to each key on the keyboard.

state

Within communication protocols, TLV (type-length-value or tag-length-value) is an encoding scheme used for informational elements. A TLV-encoded data stream contains code related to the record type, the record value's length, and finally the value itself.

It was released on June 29, 2017, by its creators Joe Taylor, K1JT and Steve Franke, K9AN, as part of the WSJT software package.

The project was created by Anton Pidkuiko and Boris Starkov.
