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:
C.What you gain as a result of choosing one option versus another;a benefit.
Explanation:
Answer:
The answer to this question can be described as follows:
a) True
b) False
c) False
d) False
e) False
f) True
Explanation:
In option a, PATA device is used to connect the hard drives into systems. Its title suggests, depends on parallel transmitting technology, contrasted to the compulsive-signaling tools.
In option b, SATA1 is a first-generation device, and SATA3 third generation, that's why it is wrong.
In option c and option d, both were wrong because RAID 0 and RAID 5 are Cloud computing software for storing data.
In option e, An internal SATA data cable with an eSATA port can not be used as an additional connection is provided by the eSATA port.
In option f, It is true because there are 7 pins in internal SATA.
