The two basic types of record-access methods are:

a. Sequential and Indexed
b. Sequential and Random

Option a. Sequential and Indexed: In sequential access, records are accessed in a specific order, one record after the other. This method is best when you need to access all the records in a file, as it starts at the beginning and goes through each one. Indexed access, on the other hand, uses an index to locate records. This method is best when you need to access a specific record quickly, without going through all the records before it.

Option b. Sequential and Random: In sequential access, as mentioned above, records are accessed in a specific order. Random access, on the other hand, allows records to be read or written in any order. The user can go directly to the record they want without going through any others. This method is best when you need to access records in a non-sequential order.

The other options, Online and Real time, and Direct and Immediate, are not typically used to describe record-access methods.
