Which Component Requires Frequent Updating?

A.

The correct answer is C. Web browser.

Explanation:

Antivirus, host firewall, and device drivers all require updates to stay effective, but not as frequently as web browsers. Here's why:

Antivirus software updates are released on a regular basis, typically once a week or more often. These updates are necessary to keep the software's virus definitions up to date, but the software itself doesn't change very often.

Host firewalls are also updated periodically, but not as often as antivirus software. Depending on the firewall and its configuration, updates may be released every few weeks or even months. Like antivirus software, the updates are usually related to improving the firewall's ability to detect and block threats.

Device drivers, which allow hardware devices to communicate with the operating system, may require updates occasionally to address bugs or add new features. However, once a driver is stable, it may not need to be updated for months or even years.

Web browsers, on the other hand, are updated frequently - sometimes as often as once a week. These updates include bug fixes, security patches, and new features. Because web browsers are used to access the internet and its constantly changing landscape, they require more frequent updates than other software components to ensure that they can keep up with evolving web standards and security threats.

In summary, while antivirus software, host firewalls, and device drivers all require updates to stay effective, web browsers require the most frequent updating to remain secure and compatible with evolving web standards.
