Final answer:
Estimation is a major problem in computers and technology because incorrect estimates can lead to incorrect results in a project.
Step-by-step explanation:
Estimation is a major problem in computers and technology because if the estimate of the number of lines of codes of the target product is incorrect, it can lead to incorrect results. For example, if the estimate is too low, it may not allocate enough resources for the project, resulting in delays or incomplete functionality. On the other hand, if the estimate is too high, it may lead to unnecessary costs and inefficient use of resources.
