Used for what???The hexadecimal system is just a way to represent information. Each byte requires two hexadecimal digits. Modern computers have billions of bytes in RAM, and often a trillion or more bytes on the hard disk, so that would be billions or trillions of hexadecimal digits. Some examples of things that are often represented as hex digits: * An IPv6 address has 16 bytes - so, 32 hex digits. * A MAC address has 6 bytes (12 hex digits). * A register has a few bytes. The size varies, but is often 2-8 bytes.

Your question is not very clear, I'm afraid, so I am going to try to guess what you mean... Hex codes are often displayed as pairs of hex (hexadecimal) digits but that is only because two hex digits fit in a byte of data storage. You can only store two hex digits in one byte. There are 16 different hex digits - 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E and F. To store any of those hex digits in binary requires 4 bits, 0 = 0000, 1=0001, 2=0010, 3=0011, ... E=1110 and F=1111. One byte is 8 bits. Therefore, with 8 bits, or one byte, you can only hold two hex digits.

IPv6 address has 2^128 address and IPv6 address is of 16 bytes and is represented in colon hex notation.
2,000,000 Bytes ~ 2 megabytes 2,000,000 B ~ 2 MB
2 bytes= 1 word so, 102400 bytes= 102400/2=51200 words
A "hextet" in IPv6 consists of 2 bytes, or 4 hexadecimal digits (as in the example in the question), or 16 bits.
1kb = 2^10 = 1024 bytes 1 mb = 2^10 = 1024 kb = 2^20 bytes = 1048576 bytes. 22222222 bytes = 21.197 mb 21 mb = 22020096 bytes that is 202126 bytes short of the given no. 202126 bytes = 197.388 kb
There are 4 bytes in 32 bits. (4 * 8 = 32)
2 bytes 8 bits in a byte
The ANSWER is 4
