Answer:
At 12:18, eighteen minutes after noon, the number of bytes infected be the same in both computers.
Step-by-step explanation:
1. Lets name PC1 the first computer and PC2 the second computer, so, at noon 1 byte of PC1 is infected with the virus, that is:
PC1
Hour Bytes infected
12:00 1
Then, every minute thereafter, the number of bytes is multiplied by two, that is:
PC1
Hour Bytes infected
12:01 2
12:02 4
12:03 8
12:04 16
12:05 32
12:06 64
12:07 128
12:08 256
12:09 512
12:10 1024
12:11 2048
12:12 4096
2. In the minute 12 after noon, 1 byte of PC2 is infected, meanwhile PC1 has 4096 bytes infected as shown above, that is:
PC1 PC2
Hour Bytes infected Bytes infected
12:12 4096 1
And each minute thereafter, the number of bytes infected in PC2 multiplied by eight, that is:
PC1 PC2
Hour Bytes infected Bytes infected
12:13 8192 8
12:14 16384 64
12:15 32768 512
12:16 65536 4096
12:17 131072 32768
12:18 262144 262144
Therefore, at 12:18, eighteen minutes after noon the number of bytes infected be the same in both computers.
