Define crt monitors and lcd monitors?

The two types of monitor technologies available to consumers are available in CRT (Cathode Ray Tube) monitors and LCD (Liquid Crystal Display) monitors. There are big differences between LCD and CRT, and while LCD technology has advanced to the point where its viewing quality is comparable to CRTs, many people today still choose to purchase a CRT monitor. CRTs are bigger and bulkier than an LCD, they consume more power and are prone to screen flicker. LCD monitors, however, are more expensive when compared to CRTs, they introduce the problem of viewing angles, and generally have less accurate color replication.
