private static String removeFromString(String old, String frag)
{
int i = old.indexOf(frag);
while (i> -1) {
String rest = old.substring(i + frag.length());
System.out.println("rest = " + rest);
old = old.substring(0, i);
System.out.println("rest = " + old);
old = old + rest;
System.out.println("rest = " + old);
i = old.indexOf(frag);
System.out.println("i = "+ i);
}
return old;
}
Here the index of first occurrence is obtained outside the “while loop” and if this loop runs until index value is >-1. It extracts the rest of the characters other than “frag” from the index and all the characters for which the given set of characters are removed.
No one could possibly know, unfortunately.
Answer:
Secure the personal information with complex multi-factor authentication and configure intrusion detection and prevention and a firewall.
Explanation:
Multi-factor authentication is a method of securing a client's personal information from the client's side to the data centre. It uses more than one security processes not policies. There key be three authentications process like a password, security token and biometrics or two authentications like password and biometrics or token.
The firewall and intrusion detection and prevention are vulnerability preventive method to detect and stop cyber attacks.
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.
