Which of the following features are taken to measure the quality of a software?MaintainabilityVisibilityDependabilityUsabilityEfficiency

The quality of a software can be measured by several features. Here are the ones you mentioned:

1. Maintainability: This refers to how easy it is to maintain the software. This includes fixing bugs, adding new features, and modifying existing ones. The easier these tasks are to perform, the higher the maintainability of the software.

2. Visibility: This is not a standard measure of software quality. It could refer to how easy it is to see and understand the software's code, which would be part of readability, a sub-characteristic of maintainability.

3. Dependability: This is a measure of how reliable the software is. It includes aspects like fault tolerance (how well the software handles errors), availability (how often the software is up and running), and security.

4. Usability: This refers to how easy it is for users to use the software. It includes aspects like how intuitive the user interface is, how easy it is to learn how to use the software, and how satisfied users are with the software.

5. Efficiency: This measures how well the software makes use of resources, like CPU time, memory, disk space, and network bandwidth. The less resources the software uses to perform its tasks, the more efficient it is.

So, all of the features you mentioned except for visibility are commonly used to measure the quality of a software.
