No. The smallest practical unit of information is the bit - which is what you get when you can have two choices, often called "yes/no", "true/false", or "one/zero". In theory, a byte can have different sizes, but it is normally standardized as 8 bits. It is the smallest amount of computer memory that can be directly addressed.
byte
A byte is the smallest data unit of modern binary computers. It represents either a 1 or a 0. Bits are compiled into a set of eight bits, known as a byte. Bytes represent one piece of data, such as a single letter, etc.
bit
ALL Computers read write store information as binary (1 and 0's) in representations of bits(smallest representation of information) and bytes (8 bits make a byte)
byte
The term used to describe smallest possible element in computer memory is byte. Some people may say bit. But logically, that's incorrect. Each character is represented by 8 bits or 1 byte. In Unicode it is represented by 16 bits or 2 bytes.
The byte is the smallest sized information that a computer works on, for example to do math or to write text. Originally computers used bytes that were 8 binary digits (bits) but the larger the byte the more can be done with each computer step computer, so soon there were 16-bit, 32-bit and 64-bit etc. computers. So the size of the byte depends on the computer, and are getting larger all the time.
Bit (b) and Byte (B) is entirely different. Bit is the smallest storage unit in computer science. 8 Bit (8b) = 1 Byte (1B) In normal working, when you press any key, it covers atleast 1 Byte of space. Means if you will type ABC, it will cover 3B, so that we consider byte as a smallest unit of useful data.
The smallest - is a byte.
a byte
1 byte = 8 bits, but that doesn't matter, a byte is the smallest amount a computer can access.
a bit is 1/8th of a byte
