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:
Option (B) is the correct answer to the following question.
Explanation:
Here, in the code "const" is the constant keyword which is used when we need that the value stored in that variable will never change.
The following option is correct because the assignment operator are those operator which initialize the value in the variable and overloading of the assignment operator would be as we use the other operators and also we could use them by creating the objects as we use in the copy constructor.
So, that's why the following option is correct.
Answer:
Option (b) When the end-user device will run an application that requires a dedicated connection to the network
Explanation:
- Option (b) is the correct option.
- When the user device requires a highly dedicated network environment to itself to run a web application that requires large download and upload speeds, bandwidth requirements then it prefers a wired connection than a wireless connection.
- If the wireless signal is within the reach, then it advisable to go for a wireless connection than a wired connection. A wired connection requires other hardware equipments like a internet connection cable etc. which is not required in case of wireless connection. So, option (a) is wrong option.
- WLAN NIC is a wireless interface network controller that connects to a wireless radio based network than a wired network.So, option (c) is wrong option.
- Delay torrent network is designed to operate where continuous network connectivity is not available like extreme terrestrial spaces, space communications, inter planetary communications etc.So, option (d) is wrong option.
Answer:
Check the explanation
Explanation:
Following are the things to be implemented immediately
Database should be maintained centralized manner so that any one can access data. Number should be given at the time of admission it should contain year of admission,course of admission …etc in the form of code eg. 2015FW1001 means year 2015 Fashion studies Winter admission no 1001. At the time of admission only they have to give the details of military status. Department which taking care of this issue should only have the permission to modify and delete the data. All the departments should be connected to the server by internet/intranet/network. Students should be given user id and password
Same database should be connected and given access through internet also with limited privileges so that user can update their status of military by submitting proof. By these information uploaded centralized administrative department update the status if they satisfied with the documents uploaded.
We can overcome the problem of mil status by giving the freedom to the student update their military status by uploading the documents.
