Every program that interacts with people responds to a specific set of commands. The set of commands and the syntax for entering them is called the user interface and varies from one program to another. The DOS operating system makes a distinction between internal and external commands.
 
        
             
        
        
        
Answer:
Option A is the correct answer for the above question.
Explanation:
- The computer is a system that processes the data to produce information. For any computer system when the data is processed then it will form the information.
- The user gives some instruction to process that can also be called the program. Then the computer takes the instruction and processes the data on behalf of the instruction and for the information because in any system when data is processed it can form the information.
- The above question says that the computer follows the instruction to process the data to produce the information which is correct as described above. Hence True is the correct answer to the above question.

Answer:
The correct answer to the following question will be Error-detection.
Explanation:
Error-detection: The detection of errors caused during the transmission from the transmitter to the receiver by damage and other noises, known as Error-detection. This error-detection has the ability to resolute if something went wrong and if any error occurs in the program.
There are mainly three types of error-detection, these types can be followed:
- Automatic Repeat Request (ARQ)
- Forward Error Correction
- Hybrid Schemes
There are two methods for error-detection, such as:
- Single parity check
- Two-dimensional parity check
