повторитель(гидроакустическое устройство, принимающее сигнал корабля и передающее его дальше с некоторой задержкой (служит для акустической маскировки корабля))
второгодник(Grade retention is the process of having a student repeat an educational course, usually one previously failed. Students who repeat a course are referred as "repeaters". Repeaters can be referred to as having been "held back" twinkie)
повторитель(Устройство, которое передаёт электрические сигналы из одного кабеля в другой без маршрутизации или фильтрации пакетов, обеспечивая лишь регенерацию сигналов. Задачей повторителя является увеличение протяжённости сети (коллизионного домена). В терминах OSI повторитель представляет собой промежуточное устройство физического уровня)
ретранслятор(1. An amplifier or other device that receives weak signals and delivers corresponding stronger signals with or without reshaping of waveforms; may be either a one-way or two-way repeater. Also known as regenerator. 2. An indicator that shows the same information as is shown on a master indicator. Also known as remote indicator. MHST. In telecommunications, a repeater is an electronic device that receives a signal and retransmits it at a higher level or higher power, or onto the other side of an obstruction, so that the signal can cover longer distances. It is a generic term that refers to several different types of devices; a telephone repeater is an amplifier in a telephone line, an optical repeater is an optoelectronic circuit that amplifies the light beam in a optical fiber cable; and a radio repeater is a radio receiver and transmitter that retransmits a radio signal. A broadcast relay station performs an analogous role in broadcast radio and television. WK Alexander Demidov); ретранслятор(AD)
