A combination of 16 bits is called a Word in computer terminology. A Bit is a single binary digit, a Nibble is 4 bits, and 1024 Bits is not a standard term for 16 bits.

A nibble is a sequence of 4 bits. A byte consists of 8 bits, a kilobyte is 1024 bytes, and a megabyte is 1024 kilobytes, so the correct answer is 'Nibble'.

When Unicode was first introduced in 1991, it was designed as a 16-bit character encoding system, allowing for 65,536 unique code points. This was intended to cover most characters needed at the time.

An 8-bit ASCII code can represent 2^8 = 256 different characters, which is why the correct answer is 256 characters.

Binary coded decimal (BCD) represents each decimal digit using a 4-bit binary number, typically from 0000 to 1001 (0 to 9). The options given (0,1; 1,1; 1,2) do not correctly represent the form of BCD encoding, so 'None of these' is the correct choice.

Among the given options, Yottabyte is the largest unit of digital storage, followed by Zettabyte, Petabyte, and Terabyte. Yottabyte represents 10^24 bytes, making it the largest unit listed.

The original 16-bit Unicode standard used 16 bits to represent each character, allowing for 2^16 = 65,536 possible characters. This is why option B is correct.

One byte consists of 8 bits, which is a standard unit of digital information storage in computer science.

EBCDIC stands for Extended Binary Coded Decimal Interchange Code, which is a character encoding system used primarily on IBM mainframe and midrange computer systems.

ASCII stands for American Standard Code for Information Interchange, which is a character encoding standard for electronic communication. This makes option A the correct answer.
