<span>The step of opening a file creates a connection between a file and a program.Opening an output file usually creates the file on the disk and allows the program to write data to it.Opening an input file allows the program to read data from the file.</span>
Answer:
Following are the difference to this question:
Explanation:
IPv4:
The 
is uses the packet changed method, that is a Link Layer networks(like Ethernet). It has 4.3 billion addresses capacity. It uses the 32-bit logical device address, that written in decimal language.
It is divided by 4 bytes E.g. 192.168.1.1
The host part and network part are 2 parts. For a network, the host part may vary, while for the entire subnet, the network part remains equal.
The scheme of 232 addresses is available on application depends on security.
IPv6:
The IPv6 is used in the internet protocoland it is higher than IPv4. It can provide endless number Opf addresses, and use to solves the problem of IPv4 exhaustion and satisfies the demand for rising networking.
IPv4 Substitutor Built to meet more IP address requirements. In the Logical address of 128-bit Written hexadecimally and with colons divided, and the Space of 128 addresses are required. IPsec is an integrated security feature.
Answer:
5) 3 0 0
Explanation:
Given data
int [] val = { 3, 10, 44 };
The total number of parameters of given array are 3, so total length of array is also 3.
The indexing of array starts with '0', Therefore the indexes of array with length zero are: {0,1,2}
The value of array at index 0 is = 3
similarly
value at index 1 = 10
value at index 2 = 44
Here, Int i = 1 is storing the value '1' in integer variable i.
In addition to that, any value of index 'i' of an array is selected using array[i].
Therefore,
val[i] = i-1 is copying the value (i-1 = 1-1 = 0) to the index '1' of the array because i = 1.
So value at index 1 would be = val[1] = 0
The term i++ is incrementing the value of i, it makes i =2
val[i] = i-1 is copying the value (i-1 = 1-1 = 0) to the index '2' of the array because i = 2 now.
So value at index 2 would be = val[2] = 0
Hence, the output would be {3 0 0}. So 5th option is correct.
Answer: Bastion host
Explanation: Bastion host is type of computer which resist the attacks happening on a network particularly. It mostly works between the internet and interior network. It assures that the interior computer network remains undamaged due to any type of threat. It can also be considered that bastion host behave as the gateway between internal network and firewall as well.
