The correct answer is: E. All of the above
Key-to-tape data-entry systems are a type of data entry system that uses a keyboard to enter data onto magnetic tape. The tape can then be used to input data into a computer or other data processing system.
Key-to-tape data-entry systems have several advantages over other types of data entry systems. First, they are very accurate. Keying errors can be detected as they occur, and the tape can be re-entered if necessary. Second, key-to-tape data-entry systems are very efficient. Data can be entered quickly and easily, and the tape can be reused multiple times. Third, key-to-tape data-entry systems are very versatile. They can be used to enter a wide variety of data, including text, numbers, and codes.
However, key-to-tape data-entry systems also have some disadvantages. First, they can be expensive to purchase and maintain. Second, they require specialized training to use. Third, they can be slow and cumbersome to use for large amounts of data.
Overall, key-to-tape data-entry systems are a versatile and accurate way to enter data. They are best suited for small to medium-sized businesses that need to enter a variety of data quickly and efficiently.
Here is a brief explanation of each option:
- A. A large percentage of editing can be performed at the time of data entry.
Key-to-tape data-entry systems allow users to edit data as it is being entered. This can help to reduce errors and improve the accuracy of the data.
- B. Key verification is easily performed.
Key-to-tape data-entry systems can be used to verify data as it is being entered. This can help to reduce errors and improve the accuracy of the data.
- C. The tape is reusable.
Magnetic tape can be reused multiple times. This can save businesses money on data entry costs.
- D. Keying errors can be detected as they occur.
Key-to-tape data-entry systems can detect keying errors as they occur. This can help to reduce errors and improve the accuracy of the data.
