One byte is composed of ____
A
1 bit
B
8 bits
C
10 bits
D
255 bits
Explanation: 

Detailed explanation-1: -A byte consists of 8 adjacent binary digits (bits), each of which consists of a 0 or 1. (Originally, a byte was any string of more than one bit that made up a simple piece of information like a single character. Thus, for example, there were four-or six-bit bytes, but eventually the standard settled on eight bits.)

Detailed explanation-2: -The 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.

Detailed explanation-3: -On almost all modern computers, a byte is equal to 8 bits. Large amounts of memory are indicated in terms of kilobytes, megabytes, and gigabytes.

Detailed explanation-4: -In most computer systems, a byte is a unit of data that is eight binary digits long. A byte is the unit most computers use to represent a character such as a letter, number or typographic symbol. Each byte can hold a string of bits that need to be used in a larger unit for application purposes.

Detailed explanation-5: -No, not every computer’s byte is sized as 8bits. A byte was defined by its creator Werner Buchholz like thus: Byte denotes a group of bits used to encode a character, or the number of bits transmitted in parallel to and from input-output units.
