Computers open and close files to read or write data {file, access}. Reading and writing can be from and to text files in linear order {sequential access}, such as appending to files. After opening sequential-access files for writing output or appending data, computers must close files before opening files for reading input. Reading and writing can be from and to records {random access}, which have addresses, such as in databases. After opening random-access files, computers can write to files and then read record without closing files first. Reading and writing can be from and to bitmaps {binary access}, which have byte positions. After opening binary-access files, computers can write to files and then read record without closing files first.
