These actions are called troubleshooting. One of the first ones would be to save your work, if you can, close all open programs and then shut down your computer (not restart). Wait a couple if minutes, start and see if the problem has been alleviated.

Answer:
User Mode
Explanation:
Programs Can be Executed in two modes namely:
- <em>User Mode</em>
- <em>Kernel Mode</em>
User Mode
In User mode, the executing program has no ability to directly access hardware or reference memory. Program running in user mode must delegate to system APIs to access hardware or memory. Due to the protection afforded by this sort of isolation, crashes in user mode are always recoverable. Most of the program running on your computer will execute in user mode.
Kernel Mode
In Kernel mode, the executing program has complete and unrestricted access to the underlying hardware. It can execute any CPU instruction and reference any memory address. Kernel mode is generally reserved for the lowest-level, most trusted functions of the operating system. Crashes in kernel mode are catastrophic; they will halt the entire PC.

Explanation:
The DNS server is said to be a caching-only DNS server.
A caching-only Domain Name System server, works by recieving queries from the client, proceeds to perform queries against other named servers, then caches the results and returns the results to the client.
Subsequent queries are resolved and returned for the specified host straight from the the cache, by the server, instead of submitting to the external server.
The advantage of this process is that it reduces traffic from outgoing DNS and speeds up the name resolution. Also, there is a reduction in the amount of query traffic.
