Domain Name Servers (DNS) are certainly necessary for easy access of resources across a network. The applicable options of the above are A and B - below are explanations as to why.
A: Computers generally are set to automatically obtain DNS information from the network they are connected to or can be pointed to a specific DNS server. This allows for records of where resources (network attach storage devices, other computers on local network, or even website server details) are located on a “master” kind of list so that the local machine’s host file does not have to be routinely updated to contain new addresses.
B: DNS, as explained partially by the answer to A, maintains a type-able or “human readable” domain name for the actual server’s IP address so we don’t have to memorize or keep a list of IPs for where we want to visit on the web (although, Google’s 8.8.8.8 IP address does make it easy). It shows an association between a name/domain name and an IP address so that we can enter something simple (Google.com) and the computer knows where to go (the server at IP address 8.8.8.8) so it can show you the content you want to see.
C: DNS would only simplify remote access if your were attempting LAN (Local Area Network) remote access of another computer on your network. DNS would not make it easier for remote access of a computer on the internet, as most DNS used in non-commercial settings are created and maintained by third-parties that will not put a specific record for one of your computers in it - not that you would want them to either, since it could lead to an open cyber attack.
D: Network throughput is a fancy phrase for network speed. It could be possible that different DNS servers could process requests faster than others, but it is not likely to increase network speed on the whole as navigating via IP or DNS records will be relatively the same speed.
Answer:A. Testimony
Explanation:when someone knows something about what happened in the case held in court or they had witnessed what happened; In order to actual testify on what they know they are called on the stand and they have to raise their hand as a sign to swear an oath before the can give their testimony in court.
I don’t understand. Please tell me the question
The program is an illustration of the square function.
The square function takes a number, and returns the square of the number; i.e. the product of the number twice.
So, the square function in Python, where comments are used to explain each line is as follows:
#This defines the square function
def square(num):
#This returns the square of the argument
return num**2
#This gets input for the number
num = int(input("Number: "))
#This calculates the square of the number
x = square(num)
#This prints the square
print("Square:",x)

Answer:
c. short-term
Explanation:
According to a different source, these are the options that come with this question:
a. long-term
b. implicit
c. short-term
d. explicit
This best illustrates the limited capacity of short-term memory. Short-term memory is the most recent information that a person holds in his head. Usually, this corresponds to events that occurred in the last 30 seconds to the last few days. This type of memory stores recent events, as well as sensory data such as sounds.
