The correct answer is: C. both (a) and (b)
A turnaround document is a document that is used both as input and output in a business process. For example, a customer order form is a turnaround document because it is used by the customer to place an order, and then it is used by the company to process the order.
Punched cards and OCR documents are both types of turnaround documents. Punched cards are cards with holes punched in them that represent data. OCR documents are documents that have been scanned and converted into text that can be read by a computer.
Both punched cards and OCR documents can be used as input to a business process. For example, a company might use punched cards to track inventory levels, or it might use OCR documents to process customer orders.
Both punched cards and OCR documents can also be used as output from a business process. For example, a company might use punched cards to generate reports, or it might use OCR documents to send invoices to customers.
Therefore, the correct answer is: C. both (a) and (b).
Here is a brief explanation of each option:
- A. punched card
A punched card is a piece of stiff paper with rectangular holes punched into it to represent data. Punched cards were widely used as a data storage and input medium from the 1920s to the 1970s. They were used in a variety of applications, including tabulating data, controlling industrial processes, and programming early computers.
- B. OCR document
An OCR document is a document that has been scanned and converted into text that can be read by a computer. OCR stands for optical character recognition. OCR technology is used to convert scanned images of text into machine-readable text. This can be done with a variety of software programs, including optical character recognition (OCR) software.
- C. both (a) and (b)
As explained above, both punched cards and OCR documents can be used as input and output in a business process. Therefore, the correct answer is: C. both (a) and (b).
- D. neither (a) nor (b)
This option is incorrect because both punched cards and OCR documents can be used as turnaround documents.
- E. None of the above
This option is incorrect because both punched cards and OCR documents can be used as turnaround documents.
