Serial access is a method of accessing data records. In order to access a data record in a serial access file, it is necessary to start at the beginning of the file and read all the preceding records. The records are not stored in any particular order.
Direct access is the fastest method of accessing records in a file. The computer can store or retreive the records without the need to read other records first. Direct access is used with magnetic disks but not with magnetic tape, which use serial access.
