apply to specific applications and programs and help ensure data validity, completeness and accuracy

manual procedures (entering data) or procedures performed by the computer

input controls help ensure that data about transactions are entered accurately into the computer, and are valid and completeness

to help insure all transactions get entered (completeness)

locked up and distribute them to users in sequence

only accept numbers within a specified range

allows you to specify how many characters should be entered

allows you to restrict type of data that a user can enter into a field

allows you to specify specific acceptable values (words or numbers) to be entered

allows you to specify acceptable combinations of values in different fields

system won't accept input until you have completed all required fields

record count: # docs compared to # of output records

Fin total: dollar amount of source docs compared to total dollar amount of output records

Hash total: summarization of non-fin field that would NOT normally be summarized (total is meaningless other than using it as a control total-making sure you processed everything in bath)

• used to insure that accuracy and proper distribution of computer generated documents and reports
• -review computer output for accuracy/completeness
• - Restricted distribution of output

• computer security issues
• software acquisition and/or development as well as software maintenance/changes

• -fire
• -uninterruptible power supplies (UPS)
• -copy of important files off premises
• -disaster recover sites (hot and cold)

recovery operating center- all necessary compute hardware in place and ready for use

empty cell- doesn't have it in place, have to arrange with vendor to deliver hardware to site- takes a while
