Answer: In banks, computers are used for keeping account information of customer accounts. Banks use technology to carry out payments effectively and successfully. Computers help bankers keep a record of and verify financial records much quicker. Hope this is helpful.
Answer:
Explanation:
Two ways of interpreting this question
(I) Shifting all the bits along with the choosen four,
in that case it will be i1>>2;
(ii) Just shifting the choosen four bits and keeping the remaining as it is.
It is equivalent to replacing the first four bits of i1 with i1>>2. let us call N = i1, and M = i1>>2.
max = ~0 //All one's
//1's through position 4, then all zeros
left = max - ((1<<4) - 1);
So we just have zeros between bits one to four and other are one.
Now final step;
(N&left) | m
Answer:
a. 255.255.255.0 (class C)
b. 255.255.255.224
Explanation:
Here, we want to give the implied subnet mask of the given classful IPV4 address
We proceed as follows;
Given IPv4 address: 200.200.200.200
Classes
Class A : 0.0.0.0 to 127.255.255.255
Class B: 128.0.0.0 to 191.255.255.255
Class C: 192.0.0.0 to 223.255.255.255
Class D: 224.0.0.0 to 239.255.255.255
so 200.200.200.200 belongs to Class C and it's subnet mask is 255.255.255.0
In CIDR(Classless Inter Domain Routing)
subnet /27 bits means 27 1s and 5 0s. so subnet
i.e 11111111.11111111.11111111.11100000 which in dotted decimal format is 255.255.255.224 .
I would have to say the answer is D.) A communication plan. Hope this helps! :-)
