What are the characteristics of software? Ans. There are six major characteristics of software: Functionality: The things that software is intended to do are called functionality. For example, a calculator's functionality is to perform mathematical operations. Efficiency: It is the ability of the software to use the provided resources in the best way possible. Increasing the efficiency of software increases resource utilization and reduces cost. Reliability: Reliability is the probability of failure-free operational software in an environment. It is an important characteristic of software.
