The primary reason that you would import data into a database is because the data already exists somewhere else.

As an example, you may have a spreadsheet that contains names and telephone numbers of a group of people. It is much faster to import this data into a database instead of manually entering the information.

The overall cost of wiring in addressable fire alarm system is significantly cheaper than the conventional one. Why is it so?

stellarik [79]

Answer:

Yes, The overall cost of wiring in addressable fire alarm system is significantly cheaper than the conventional one.But the addressale fire alram system is more reliable than a conventional system.

Explanation:

Conventional systems are hardware-based and use analog technology. where addressable fire alarm use digital technology. addressable system is generally more reliable than a conventional system mainly due to how the different systems are wired. With a conventional system, if a device’s wire is damaged or severed, its signal and the signal of other devices down the line cannot be transmitted to the control panel.

With an addressable system, both ends of the wire connect to the control panel. Therefore, if one end becomes damaged or severed, signals can still reach the control panel through the other end of the loop. In addressable systems, a device can be removed or disabled and it will not affect the other devices in the loop.

As the security administrator for your organization, you must be aware of all types of attacks that can occur and plan for them.

Aliun [14]

Answer:

The answer is "DDoS "

Explanation:

The distributed denial of service attack (DDoS) occurs whenever a directed program's wireless data or assets, generally one or even more application servers, were also swamped by various machines. This attack is always the consequence of many affected systems, that fill up the target network with traffic.

This attack is aimed to avoid legal customers of one's website from accessing it.
In being effective in a DDoS attack, further demands need to be sent to the hacker than even the victim's server could deal with.
One other way to successfully attack is to send fake requests from the attacker.
