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.
a. speed + 12 - miles * 2 = 10 + 12 - 5 * 2. With order of operations, we do the multiplication first so the equation is now 10 + 12 - 10 = 22 - 10 = 12
b. speed + miles * 3 = 10 + 5 * 3 and again, order of operations gives us 10 + 15 = 25
c. (speed + miles) * 3 = (10 + 5) * 3 = 15 * 3 = 45
d. speed + speed * miles + miles = 10 + 10 * 5 + 5 = 10 + 50 + 5 = 60 + 5 = 65
e. (10 – speed) + miles / miles = (10 - 10) + 5 / 5 = 0 + 5 / 5 = 5 / 5 = 1
Answer:
Policy manual
Explanation:
A written document that is designed by the company to decide the rules and regulations for the employee to guide them about attendance and evaluation to achieve the desired goals is called Policy manual.
A handbook is provided to the employee at the time of joining of Job. All the policies related to employee such as dress code, attendance policy and evaluation policy. All the rules and regulations related to office are also present in this document.
The purpose of this document is to inform the new employees about guidelines of the company.
You can install Eclipse. If you want you can look into the Ubuntu store and see if they have any.
Answer:
The matrix theory is used by hill cipher.
Explanation:
Th technique which uses matrix theory is hill cipher technique.
Hill cipher technique is a polygraphic substitution cipher and it is based on linear algebra.
For encrypting a message in Hill Cipher technique each block of n letters is multiplied by an invertible matrix of nxn and that to against modulus 26 and for the decryption of the message, every block is multiplied by the inverse of the matrix that was used for encryption.
