Free services are offerings that do not require payment from users. These services can include anything from basic software applications to online platforms that provide information or entertainment. Many companies use free services as a way to attract users, hoping they will eventually pay for premium features or products. Common examples of free services include social media platforms like Facebook and Twitter, which allow users to connect and share content without any cost. Additionally, many websites offer free educational resources, such as Khan Academy, which provides lessons and tutorials on various subjects to help learners of all ages.
