Twitter is one of the social networks and is often referred to as a short message service or microblogging service. Users post so-called tweets, which can be supplemented with images, videos, links, tagging (marking), locations or hashtags.
The tweets are usually publicly viewable, and a wide audience can be reached through appropriate hashtags, links or retweets. However, there is also the possibility to post protected posts, these are only accessible to accepted followers. In general, tweets can be shared (retweeted), liked and commented on, and personal messages can be sent.
