CSS MCQs — General Science Abbreviations
- NTP — Network Time Protocol (CSS 2003, Everyday Science Paper)
- It is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. NTP was designed by David L. Mills.
- CFC — Chlorofluorocarbons (CSS 1996 & 2002, Everyday Science Paper)
- BCG — Bacille Calmette-Guerin (CSS 2003, Everyday Science Paper)
- It is a vaccine for tuberculosis (TB) disease. Many foreign-born persons have been BCG-vaccinated. BCG is used in many countries with a high prevalence of TB to prevent childhood tuberculous meningitis and military disease.
- RQ — Respiratory Quotient (CSS 2003, Everyday Science Paper)
- It also known as the respiratory ratio (RQ), is defined as the volume of carbon dioxide released over the volume of oxygen absorbed during respiration. It is a dimensionless number used in a calculation for basal metabolic rate when estimated from carbon dioxide production to oxygen absorption.
- NPN — Negative-Positive-Negative (CSS 2003, Everyday Science Paper)
- PNP — Positive-Negative-Positive transistors (CSS 2004, Everyday Science Paper)
- STP — Standard Temperature and Pressure (CSS 2004, Everyday Science Paper)
- It is defined as 0 degrees Celsius and 1 atmosphere of pressure.
- MAF — million acre feet (CSS 2004, Everyday Science Paper)
- McV — Means Cell Volume (CSS 2005, Everyday Science Paper)
- UHF — Ultrahigh Frequency (CSS 2005, Everyday Science Paper)
