The correct answer is D. All of the above.
The transfer vector approach of linking is a method of linking two or more modules together. It uses a table of addresses, called a transfer vector, to locate the code and data for each module. The transfer vector is stored in the first few bytes of each module.
When a module is loaded, the transfer vector is used to locate the code and data for the module. The code and data are then loaded into memory and the module is ready to run.
The transfer vector approach of linking is a simple and efficient way to link modules together. It is often used in embedded systems where memory is limited.
A. External data segments can be accessed by the transfer vector approach of linking. The transfer vector contains the address of the data segment in memory.
B. External subroutines can be accessed by the transfer vector approach of linking. The transfer vector contains the address of the subroutine in memory.
C. Data located in other procedures can be accessed by the transfer vector approach of linking. The transfer vector contains the address of the procedure in memory.
E. None of the above is not the correct answer.
