        Answer:

         The name "4K resolution" refers to a horizontal resolution of approximately 4,000 pixels. It has been  developed into a variety of standards. The DCI 4K resolution standard (4096 * 2160 pixels) is widely respected  by the film and   video production industry. Besides, UHDTV standard (3840 * 2160 pixels) is also popular  which has twice the  horizontal and vertical resolution of 1080p (as shown in the figure below)                               

            

 

            Answer:

           Generally speaking, the image on TV could be divided into many horizontal lines which are also called TV lines.A higher number of the horizontal lines means that a camera will be able to render images with more details.
 

            Answer:

            Resolution is usually measured by the number of horizontal and vertical pixels. It can be expressed as number of horizontal point * number of vertical pixels. In a fixed plane, the higher resolution could provide better image.
