Answer: Computers as target
Explanation:
Whenever an authorized  access is made into a system it is a form of crime and it is called computers as target whereby one is able to access the system and get hands on unauthorized data and can also manipulate various activities which will have many dangerous effects.
 
        
             
        
        
        
<span>When studying an information system, illustrations of actual documents should be collected using a process called sampling. Correct answer: D
</span>This process systematically selects representative elements of a population with the goal to get representative and useful information about the population as a whole and it is useful when <span>data sets that are too large to efficiently analyze in full.</span>
        
             
        
        
        
Here are a few examples:
•] Keep away from windows or vents to prevent it from turning warm.
•] Clean off dust that’s on the computer.
•] Remove all the things that are blocking air to pass to let it cool down.
•] Putting a soft item below the computer is a action that is prohibited as it blocks the airways which causes it to overheat instead put it on a sturdy flat surface to prevent the aforementioned information. 
•] To never overcharge your computer too 100% overnight or any time of the day since it overheats and causes battery life to be short, instead put it to charge when you’re conscious while keeping an eye on it, perhaps set a timer/alarm to notify you if you forget.
        
             
        
        
        
Answer is 
(HMAC)
Hashed Message Authentication Code
This combines authentication via a shared secret
cryptography algorithm key with hashing. It involves the client and server each
with a private key. The client creates a unique hash per request to the server
through hashing the request with private keys.
 
        
             
        
        
        
Answer:
NTSC, Timecode
Explanation:
NTSC was used for television broadcasting in the USA, and some other countries. And it archives a video signal that exceptionally deciphers every frame of the tape with the assistance of the time stamp in unit time and frames. We have other options as well, which are PAL and SECAM. However, now and since 2013, these are being converted into the digital. The frame rate of the NTSC in the US was 29.97 fps. And this defines how good video you are going to receive.
And timecode is the signal that is recorded with the video that can quite exclusively figure out each frame of the tape with the help of the time stamp in unit time and frames.
