Low-tech servers are a type of server that uses older, less advanced technology than more modern servers. They are often used in situations where the cost of a more advanced server is too high or the environment does not require the use of more advanced technology. The term 'low-tech servers' can be broken down into two words: 'low-tech' and 'servers'. Rackets is a seven-letter word that can be used to describe low-tech servers, as it refers to an old-fashioned way of doing something.
