CRT stands for Cathode Ray Tube.
CRT is the traditional technology used for televisions and Computer Monitors. It preceded the LCD (Liquid Crystal Display) and plasma technologies that are now being used on new models.
Technically speaking, CRTs are vacuum tubes. Images are created when a beam of electrons scans back and forth across the back of a phosphor-coated screen.
LCD and plasma screens are slimmer and usually lighter than a CRT.
But will never be as good for uniform picture brightness and colour. The resolution (horizontally anyway) will never but that of a CRT.
The cathode ray tube (CRT) is an evacuated glass envelope containing an electron gun (a source of electrons) and a fluorescent screen, usually with internal or external means to accelerate and deflect the electrons. When electrons strike the fluorescent screen, light is emitted.
The electron beam is deflected and modulated in a way which causes it to display an image on the screen. The image may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), echoes of aircraft detected by radar, etc.
The single electron beam can be processed in such a way as to display moving pictures in natural colors.
The generation of an image on a CRT by deflecting an electron beam requires the use of an evacuated glass envelope which is large, deep, heavy, and relatively fragile (this has earned it the nickname "Fishbowl"). The development of imaging technologies without these disadvantages has caused CRTs to be largely displaced by flat plasma screens, liquid crystal displays, DLP, OLED displays, and other technologies.
An exception to the typical bowl-shaped CRT would be the flat CRTs used by Sony in their Watchman series (the FD-210 was introduced in 1982). One of the last flat-CRT models was the FD-10A. The CRT in these units was flat with the electron gun located roughly at right angles below the display surface thus requiring sophisticated electronics to create an undistorted picture free from keystoning and the like.

Why is cathode ray tube considered the heart of an oscilloscope?
Well, a CRT used to be the only practical display device for an oscilloscope (as a CRT was also the only practical display device for a television), but now flat panel displays (e.g. LCD, LED) have replaced the CRT in many oscilloscopes (as they have in television) because they are lighter weight, more compact, and are becoming less expensive than CRTs.
What is a lightwieght display device with a shallow depth such as an LCD monitor or plasma monitor that does not use CRT technology?

Is crt an output or input device?
Most CRTs were used in output devices. However some CRTs were used in input devices as flying spot scanners to scan microfilm documents into the computer. This function has generally been replaced by LASER scanners, which can be used on opaque documents that the CRT could not scan.
What is device which receives electrical impulses and restores them to a visual form with a modified cathode ray tube?
That would be a CRT Monitor (CRT stands for Cathode Ray Tube), or the big clunky monitor that you had such a hard time getting rid of when you got your LCD

A degaussing coil is a device used to remove a residual magnetic field, usually from a Cathode Ray Tube (CRT).
