What are advantages and disadvantages of digital system?

Advantages

• Have made possible many scientific, industrial, and commercial advances that would have been unattainable otherwise.
• Less expensive
• More reliable
• Easy to manipulate
• Flexibility and Compatibility
• Information storage can be easier in digital computer systems than in analog ones. New features
• can often be added to a digital system more easily too. 

Disadvantages of digital system:

• Use more energy than analog circuits to accomplish the same tasks, thus producing more heat as well.
• Digital circuits are often fragile, in that if a single piece of digital data is lost or misinterpreted the meaning of large blocks of related data can completely change.
• Digital computer manipulates discrete elements of information by means of a binary code.
• Quantization error during analog signal sampling.
