Answer:Waterfall, Unified
Explanation:
The Waterfall model of software development doesn't allow for revisiting previous stages, in contrast to the Agile model which allows for continual revisiting and modification.
The Waterfall model does not allow you to revisit previous stages of the software life cycle; the Agile model does allow previous stages to be revisited. These are both models used in software development. The Waterfall model is a linear approach, where each phase must be completed before moving on to the next one, meaning once a phase has been completed, it is not revisited. On the other hand, the Agile model is iterative, allowing for constant revisions and adaptation throughout development, hence making it possible to revisit previous stages.

A computer virus is a program that is installed without the permission or knowledge of the computer user.
It is designed to alter the computer's normal operations and can replicate itself to infect other files, programs, or media it can access. Computer viruses are malicious and often spread through infected files, emails, or downloads.
Once inside a computer system, they can cause various damages, such as corrupting data, stealing personal information, or disrupting the computer's functionality.
As they replicate, they can rapidly spread to other devices and networks, making them a significant threat to the security and integrity of computer systems worldwide.
Protecting against viruses requires robust antivirus software and cautious online behavior.
