Answer:
D. 25x24x23x22x21.....3x2x1.
Explanation:
The ceasar cipher is a encryption technique, that uses a combination of information or keys to encrypt an information.
The 25 shift ceasar cipher has 25 different combinations, so the number of probable random cipher substitution is 25!,
That is = 25 × 24×23× 22×..... ×2×1.
Answer:
a: Twisted pair won't span a 400-foot distance.
Explanation:
The maximum distance that twisted pair cables can support without attenuation is 100 meters which is approximately 328 feet and the two office buildings are 400 feet apart, so it is useless to install a twisted pair cable for such a large distance. A much better option would be to install optic fiber. Though it is a bit expensive but it is the best option in this case.
Hence option (a) is the correct reason for installing an optic fiber cable rather than a twisted pair cable.
Answer:
4160000 bytes
Explanation:
One page = 52 lines of text
One line of text = 80 characters
=> One page = 80 x 52 = 4160 characters
Therefore, 500 pages of text will have 4160 x 500 characters = 2080000 characters.
Since 1 character takes up 2 bytes of computer memory, it impleies that a 500 page novel will take up 2080000 x 2 bytes = 4160000 bytes.
