Correct Answer - Option 1 : 8-bits

• The smallest unit of data in a computer is called the bit.
• The Bit is the acronym of Binary Digit.
•  A bit has a single binary value, either 0 or 1
• The data will be transformed to its binary form.
• 1 byte = 8 bits
• 1 kilobyte (KB) = 1024 bytes
• 1 megabyte (MB) = 1024 kilobytes
• 1 gigabyte (GB) = 1024 megabytes
• 1 terabyte (TB) = 1024 gigabytes
• 1 petabyte (PB) = 1024 terabytes

• Bit (Binary Digit):
• A binary digit is logical 0 and 1 representing a passive or an active state of a component in an electric circuit.
• Nibble:
• A group of 4 bits is called a nibble.
• Byte:
• A group of 8 bits is called a byte.
• A byte is the smallest unit, which can represent a data item or a character.
• Word:
• A computer word, like a byte, is a group of a fixed number of bits processed as a unit, which varies from computer to computer but is fixed for each computer.
• The length of a computer word is called word size or word length.
• It may be as small as 8 bits or maybe as long as 96 bits.
• A computer stores the information in the form of computer words.
