Which internet explorer security feature restricts the browsing session information that can be tracked by external third-party
Anarel [89]

Tracking protection internet explorer security feature restricts the browsing session information that can be tracked by external third-party websites and applications

The internet can be a dangerous place, and it's important to take steps to protect your privacy. One way to do this is to enable tracking protection in your web browser.

Tracking protection is a security feature that restricts the information that can be tracked by external websites and applications. This means that your browsing session will be more private, and your data will be less likely to be collected and used without your consent.

To enable tracking protection in Internet Explorer, go to the Tools menu and select Internet Options. On the Privacy tab, click the Tracking Protection button. You can then choose to enable tracking protection for all websites, or only for certain websites that you trust.

Enabling tracking protection can help to keep your data safe and your privacy protected. So if you're concerned about online privacy, be sure to enable this feature in your web browser.

Brums [2.3K]
From January 2005 through July 2017, approximately 853 million electronic data records in the US were breached.
This allowed the attackers to take control over people's personal data, such as their various credit card numbers, and other important data, as well as their addresses, etc. The cyber police, as well as the regular police have been working hard to stop this from happening, but the hackers are very strong and smart.

ACTIVITY NO. 5 (DAY 5) FACT OR BLUFF. Write Fact if the statement is correct and write Bluff if it is incorrect.
KengaRu [80]

All of the above are Facts.

preventive maintenance does indeed help with the lifespan etc.

If you are feeling tired or fatigued when operating machinery, stop and rest for fear of mistake. So , two is also correct

4if you dress inappropriately it may cause danger from getting caught in machinery or catching a flame depending on the worksite. so four is correct. Newer models are most likely more updated and have different operations then the last machine. so yes read the manual before using it. so yet again 5 is also correct.

hopefully this helped

What are the advantages of renting a home over buying a home? What are some disadvantages?
weqwewe [10]
An advantage of renting a home is that you don't have to fix any appliances or structures of the home your landlord does that for you. disadvantages are you have to follow their rules, you can't change anything on the inside like the paint or add a room to the home. in the state of Washington and landlord can evict you with only 20 days notice if they want to permanently sell the property. that's called a no-fault eviction. that's all I can think of hope that helps
