A BCD digit only uses the binary patterns that represent decimal numbers, ie 0000 - 1001; this requires 4 bits (1 nybble) so there can be 2 BCD digits to a byte. Therefore in 3 bytes there can be 3 × 2 = 6 BCD digits. The largest BCD digit is 1001 = 9.
Assuming non-signed, the maximum 3 byte BCD number is 999,999.
It depends what exact system is used - it seems there are several methods to encode numbers as BCD.For example, if "packed" BCD is used (two digits per byte), and one nibble (half-byte) is reserved for the sign, that allows a total of 5 decimal digits.

The Largest 4Bytes Hex number is FFFF FFFF which is 65535 in decimal.
If using the compressed format, where a byte holds two decimal digits (because only 4 bits are needed to make nine), so two bytes would be four decimal digits, the largest which is 9999.

I would say a monoicosebyte which is an astonishing 1,000,000,000,000,000,000,000,000,000,000,000,000,000 bytes. This unit of storage will most likely never come up due to how large this unit of measurement is for storage. I bet that there isn't even a single device on earth that can hold this many bytes.
A Kilobyte is equal to 1000 bytes

11b which is 1*2 + 1*1 = 3 would be for two bits. But a byte is 8 bits, so 2 bytes is 16 bits. The largest binary number is [2^16 - 1], which is 65535 (base ten)
1024 bytes is binary counting while 1000 bites is decimal counting.
A Mac address is a 48bit addressing scheme (usually represented in HEX). There are 8 bits in a bytes therefore it is 6 bytes long.
Tera Bytes are the largest unit of measurement.
The way "gigabyte" is usually used, it means 10243 bytes. In other words, 1,073,741,824 bytes.
A zettabyte is a massive amount of bytes and referencing from wikipedia (yes it is correct) it is 1,000,000,000,000,000,000,000 bytes in decimal or 1021
GB or gigabytes
Yes. The standard definition is now 10^6 bytes. Historically, it could have represented 1,048,576 bytes (2^20 bytes), a value now defined as a mebibyte (million-binary byte).
Four bytes represent 32 bits. 32 bits represent 4,294,967,296 possibilities.
