Explanation: search engine uses system algorithm to search out items or information as required by the user. Example is google, chrome.
Data base are archives where information could be retrieve. Its contain information such as publications, abstract,journals.
Search engine provides wide range of information depending on you request while database are mostly for academics related materials.
Data base- A good place to generate this information is library, archivals while journal, publiications are kept while search engine can be used anywhere you have an internet facilities.
In a data base, information is searched in an organized way. The collections are already well arranged in different cubicle search engine provides wide range of information not organized.
Data base may contain more complex information not easily understood, search engine provides more elaborate answers.
Similarity of the two is that they both provide information.
They are both reliable.

Answer:
Control is transmitted to the operating system when an interrupt happens, which determines what action is to be done to be taken or usually what interrupt services.
- If the kernel leaves data in the memory space of a user program when returning from a system call, it may be possible for a malicious user to use this data to find out about other processes.
- In these systems, the kernel synchronizes by preventing interrupts in critical sections with interrupt handlers on a processor.
- Operating system may crash if it controls the interrupts because a poorly written user program does not provide sufficient stacking room.
