Personal communication refers to the exchange of information, ideas, and thoughts between individuals. It involves direct interaction and typically occurs between people who know each other personally. Personal communication can take various forms, such as letters, telephone calls, and emails. However, newspapers are not considered a form of personal communication.

- Letters: Letters are written messages exchanged between individuals. They are usually sent through postal services and can be used to convey personal thoughts, feelings, and information. Letters can be handwritten or typed and are often used for more formal or lengthy communication.

- Telephone: Telephones allow individuals to communicate verbally in real-time, even if they are physically distant from each other. This form of personal communication enables people to have direct conversations, ask questions, and share information promptly. It is a popular method of communication due to its convenience and immediacy.

- E-mail: With the advancement of technology, email has become a common and widely used form of personal communication. Emails are electronic messages exchanged between individuals through the internet. They allow for the transmission of written messages, documents, and multimedia files. Emails provide a quick and efficient way of communication, especially for individuals who are geographically separated.

- Newspaper: Although newspapers are a means of communication, they do not fall under the category of personal communication. Newspapers are a form of mass communication that disseminate information, news, and opinions to a wide audience. They are published and distributed to the general public, rather than being personalized for specific individuals. Newspapers serve as a source of information for the public and cover various topics such as politics, sports, entertainment, and more.

In conclusion, while letters, telephone calls, and emails are considered forms of personal communication, newspapers are not. Personal communication involves direct interaction between individuals, whereas newspapers are a form of mass communication intended for a larger audience.
