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:
ISO 27002
Explanation:
The acronym ISO stand for The International Organization for Standardization. its a non governmental body that is responsible for setting standards guide internationally.
while NIST stand for National Institute of Standards and technology and it is also a body that is responsible for setting up standard guide in the US..
ISO 27002 is a standard code for implementing information security management systems. while ISO 27017 is for cloud security. NIST 800-12 is a general security and NIST 800-14 is for policy development. thus option A is correct.
Note :
All code preceded by ISO is from The International Organization for Standardization and are international standard. while those preceded by NIST is from National Institute of Standards and technology and are not international standard.
The base-10 value of 52010 is equal to base-16 value of 20816.
Answer:
#include <iostream>
#include <cstdlib>
using namespace std;
int m, n;
void transpose(int matrix[]){
int transp[m][n];
for (int i = 0; i < n; i++){
for (int j = 0; j < m; j++){
transp[j][i] = matrix[i][j];
cout<< transp[j][i]<< " ";
}
cout<< "\n";
}
}
int main(){
cout<< "Enter the value for n: ";
cin>> n;
cout>> "Enter the value for m: ";
cin>> m;
int mymatrix[n][m];
for (int i = 0; i < n; i++){
for (int j = 0; j < m; j++){
mymatrix[i][j] = (rand() % 50);
}
}
transpose(mymatrix);
}
Explanation:
The C source code defined a void transpose function that accepts a matrix or a two-dimensional array and prints the transpose on the screen. The program gets user input for the row (n) and column (m) length of the arrays. The C standard library function rand() is used to assign random numbers to the array items.
