| Term | Context | Explanation |
| 2 wire | telephone line, modems | normal physical connection so both transmission directions co-exist in full-duplex |
| 4 wire | telephone line, modems | physically separate 2-wire lines for each modem transmission direction in full-duplex |
| <= | - | less than or equal to |
| ANSI | standards | American National Standards Institute |
| asm | software | assembler (machine language) |
| b/s | units | bits per second (so kb/s is kilo-bits/sec) |
| Bell | standards | interoperability standards for modems prevalent in the USA - eg Bell 202 |
| BER | modem data transmission | Bit Error Rate (or error rate) |
| BW | signals | bandwidth |
| byte | memory | 8-bit element |
| Caller ID | telephone dialling | Caller IDentification |
| CID | ||
| CRC | data error detection | Cyclic Redundancy Check (added to data stream) |
| Error Rate | modem data transmission | for example "10-6 error rate" means 1 data bit in every 1000000 data bits in error on average |
| Term | Context | Explanation |
| FFT | signals | Fast Fourier Transform |
| fixed-point | DSP-/micro-processor arithmetic and program/data storage | integer number expression: an example is signed 16 bits where the numerical range is +32767 to -32768 |
| full-duplex | modem data transmission | transmission and reception in both directions simultaneously |
| half-duplex | modem data transmission | transmission or reception in one direction only at a time but capability of either |
| ITU | standards | International Telegraph Union: body which sets world-wide interoperability standards for eg telephone modems - V.xx designations - and speech/audio coders - G.xxx standards |
| k | units | kilo |
| lsb | DSP-/micro-processor arithmetic | least significant bit |
| MIPS | DSP-/micro-processor processing power unit | Millions-of-Instructions-per-Second |
| re-entrant | software | the same routine call can be used to process multiple instances of a function |
| SNR | signals property, often in data transmssion | Signal-to-Noise Ratio |
| word | DSP-/micro-processor program/data storage | a 16-bit integer value or "short int" in C vernacular |
