A TXT record, as the abbreviation implies, is a record, which holds information in human-readable form and not code. It could be created for a domain or a subdomain for various purposes. Search engines like Yahoo, for instance, have different ways of verifying that you are the owner of a particular domain name and one of them is in fact by creating a TXT record with unique text which they provide and that you will need to use as the record value. Exactly the same verification method is used by some analytics platforms that check the traffic to your sites as well. Needless to say, in this situation the content of the record will be read by a robot, but it'll still be in human-readable form. A TXT record is additionally employed if you enable the so-called SPF protection for your e-mails in order to shield them from being forged. In this situation, the record contains info showing that a certain digital message is sent from a trusted and authorized mail server. You could use a TXT record for any kind of other information also, just like your business details, for example.
