Screen Recording: Capturing a Video of the Screen's Activity

Screen Recording involves capturing a video of the activities performed on a computer or mobile screen. This technique is widely used for creating tutorials, presentations, and more.

Screen recording has evolved from basic screen capture tools to sophisticated software capable of high-definition video and audio capture. The history of screen recording dates back to early computing when simple screenshots were used. With the advent of multimedia and digital education, screen recording has become an essential tool for content creators, educators, and professionals.
