Multimedia uses computers to integrate text, graphics, video, animation, and sound. It is used for English teaching in classrooms with personal computers, video players, amplifiers, projectors, and screens connected to the internet. Multimedia in English teaching is necessary for modern educational technology development, engaging students' cognitive abilities, and providing a platform for quality education. It improves students' self-learning, innovation, and communication skills, but may distract students or make teachers over-reliant on the technology.
