Question

What is frame?
AND
What is the use of layers?​

Answer 1

Answer:

In the OSI model of computer networking, a frame is the protocol data unit at the data link layer. Frames are the result of the final layer of encapsulation before the data is transmitted over the physical layer.

Answer 2

• The frame is a single image in a sequence of pictures. In general, one second of a video is comprised of 24 or 30 frames per second also known as FPS. The frame is a combination of the image and the time of the image when exposed to the view. An extract of frames in a row makes the animation.
• Layers are useful for many purposes, including compositing multiple images, adding vector graphic shapes, and adding text to an image.
