Question: Passage: DECnet is a suite of network protocols created by Digital Equipment Corporation, originally released in 1975 in order to connect two PDP-11 minicomputers. It evolved into one of the first peer-to-peer network architectures, thus transforming DEC into a networking powerhouse in the 1980s. Initially built with three layers, it later (1982) evolved into a seven-layer OSI-compliant networking protocol. The DECnet protocols were designed entirely by Digital Equipment Corporation. However, DECnet Phase II (and later) were open standards with published specifications, and several implementations were developed outside DEC, including one for Linux. Question: What is  DECnet

Answer: a suite of network protocols created by Digital Equipment Corporation


Question: Passage: BSkyB's standard definition broadcasts are in DVB-compliant MPEG-2, with the Sky Movies and Sky Box Office channels including optional Dolby Digital soundtracks for recent films, although these are only accessible with a Sky+ box. Sky+ HD material is broadcast using MPEG-4 and most of the HD material uses the DVB-S2 standard. Interactive services and 7-day EPG use the proprietary OpenTV system, with set-top boxes including modems for a return path. Sky News, amongst other channels, provides a pseudo-video on demand interactive service by broadcasting looping video streams. Question: What is Sky+ HD material broadcast using?

Answer: MPEG-4


Question: Passage: Ranging from about 1 millimeter (0.039 in) to 1.5 meters (4.9 ft) in size, ctenophores are the largest non-colonial animals that use cilia ('hairs') as their main method of locomotion. Most species have eight strips, called comb rows, that run the length of their bodies and bear comb-like bands of cilia, called 'ctenes,' stacked along the comb rows so that when the cilia beat, those of each comb touch the comb below. The name 'ctenophora' means 'comb-bearing', from the Greek κτείς (stem-form κτεν-) meaning 'comb' and the Greek suffix -φορος meaning 'carrying'. Question: What are cilia used for?

Answer:
method of locomotion
