The Amiga is a family of personal computers introduced by Commodore in 1985.
Amplitude-shift keying (ASK) is a form of amplitude modulation that represents digital data as variations in the amplitude of a carrier wave.
In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically 0 (zero) and 1 (one).
The bit (a portmanteau of binary digit) is a basic unit of information used in computing and digital communications.
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.
Data is a set of values of qualitative or quantitative variables.
In telecommunications, data-transfer rate is the average number of bits (bitrate), characters or symbols (baudrate), or data blocks per unit time passing through a communication link in a data-transmission system.
Differential Manchester encoding is a line code in which data and clock signals are combined to form a single 2-level self-synchronizing data stream.
A floppy disk, also called a floppy, diskette, or just disk, is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic enclosure lined with fabric that removes dust particles.
Frequency is the number of occurrences of a repeating event per unit of time.
In telecommunications and signal processing, frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave.
In computer science, group coded recording or group code recording (GCR) refers to several distinct but related encoding methods for magnetic media.
A hard disk drive (HDD), hard disk, hard drive or fixed disk is an electromechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.
In mathematics and computing, hexadecimal (also base, or hex) is a positional numeral system with a radix, or base, of 16.
IBM manufactured magnetic disk storage devices from 1956 to 2003, when it sold its hard disk drive business to Hitachi.
IBM PC compatible computers are computers similar to the original IBM PC, XT, and AT, able to use the same software and expansion cards.
In boolean logic, logical nor or joint denial is a truth-functional operator which produces a result that is the negation of logical or.
In telecommunication, a non-return-to-zero (NRZ) line code is a binary code in which ones are represented by one significant condition, usually a positive voltage, while zeros are represented by some other significant condition, usually a negative voltage, with no other neutral or rest condition.
Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency reference signal (the carrier wave).
Propagation delay is a technical term that can have a different meaning depending on the context.
Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.
Run-length limited or RLL coding is a line coding technique that is used to send arbitrary data over a communications channel with bandwidth limits.
Signal-to-noise ratio (abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.
In telecommunication, signaling has the following meanings.
