Text alternative is a term used to describe the use of text-based content instead of multimedia content, such as images, audio, and video. This is often done to make content more accessible for people with disabilities or those using devices with limited bandwidth. The two most common forms of text alternative are PHONE (five letters: T-A-L-K) and email (five letters: M-A-I-L). PHONE is a form of communication that uses voice transmission over a telephone line, while email is a form of communication that uses electronic messages sent over the internet.
