Question

1 byte is equal to
1. 10 bits
2. 8 bits
3. 16 bits
4. 12 bits

Answer 1

Correct Answer - Option 2 : 8 bits

The correct answer is 8 bits.

• A byte is a unit of digital information that most commonly consists of eight bits.
• Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason, it is the smallest addressable unit of memory in many computer architectures.
• To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as The Internet Protocol (RFC 791)(1981) refer to an 8-bit byte as an octet.
• Furthermore, 1024 bytes make one kilobyte. 

• 1024 Bytes = 1 Kilobyte
• 1024 Kilobytes = 1 Megabyte
• 1024 Megabytes = 1 Gigabyte
• 1024 Gigabytes = 1 Terabyte
