An election recount is a repeat tabulation of votes cast in an election that is used to determine the correctness of an initial count. Recounts will often take place if the initial vote tally during an election is extremely close. Election recounts will often result in changes in contest tallies. Errors can be found or introduced from human factors, such as transcription errors, or machine errors, such as misreads of paper ballots.

A voting machine is a machine used to record votes in an election without paper. The first voting machines were mechanical but it is increasingly more common to use electronic voting machines. Traditionally, a voting machine has been defined by its mechanism, and whether the system tallies votes at each voting location, or centrally. Voting machines should not be confused with tabulating machines, which count votes done by paper ballot.
