CSS MCQs — General Science Abbreviations
- RAM — Random Access Memory (CSS 1996, Everyday Science Paper)
- ROM — Read-only Memory (CSS 2002, Everyday Science Paper)
- RAM and ROM are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
- AIDS — Acquired immunodeficiency syndrome (CSS 2002, Everyday Science Paper)
- It is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus (HIV). By damaging your immune system, HIV interferes with your body’s ability to fight infection and disease.
- RADAR — Radio Detection and Ranging (CSS 2002, Everyday Science Paper)
- Radar is a detection system that uses radio waves to determine the distance, angle, or velocity of objects. Radars are now used to help navigate ships in fog and airplanes in bad weather. Radar can detect a speeding car and track a satellite. Most importantly for meteorologists, radars can detect all sorts of atmospheric phenomena.
- LASER — Light amplification by the stimulated emission of radiation (CSS 2002, Everyday Science Paper)
- A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
- PVC — Poly Vinyl Chloride (CSS 1996 & 2002, Everyday Science Paper)
- LAN — Local Area Network (CSS 2002, Everyday Science Paper)
- A local area network (LAN) consists of a series of computers linked together to form a network in a circumscribed location. The computers in a LAN connect to each other via TCP/IP ethernet or Wi-Fi. A LAN is normally exclusive to an organization, such as a school, office, association or church. IP stands for “Internet Protocol,” which is the set of rules governing the format of data sent via the internet or local network. Wi-Fi (Wireless Fidelity) is the wireless technology used to connect computers, tablets, smartphones and other devices to the internet. Wi-Fi is the radio signal sent from a wireless router to a nearby device, which translates the signal into data you can see and use.
- WAN — Wide area network (CSS 2003, Everyday Science Paper)
- It is a large network of information that is not tied to a single location. WANs can facilitate communication, the sharing of information and much more between devices from around the world through a WAN provider.
