There is no wear, aging, aging and other problems in the long-term operation and use of the software. In the operation and use of any mechanical and electronic equipment, its failure rate mostly follows the U-shaped curve . That is because the parts are not yet flexible when they are first put into use, and they are often prone to problems. After a period of operation, it can be stabilized. When the equipment has experienced a considerable period of operation, there will be wear, aging and other problems, which will suddenly increase the failure rate. This means that it has reached the end of life and is about to be scrapped.
The statement 'The performance of software is very different from that of mechanical and electronic equipment in operation and use' does not fit the meaning of the article.
