A string of eight 0s and 1s is called a:
A
megabyte
B
byte
C
kilobyte
D
gigabyte
E
bit
Explanation: 

Detailed explanation-1: -A string of eight 0’s or 1’s called a Byte. A byte consists of 8 adjacent binary digits (bits), each of which consists of a 0 or 1. The string of bits making up a byte is processed as a unit by a computer; bytes are the smallest operable units of storage in computer technology.

Detailed explanation-2: -What is a byte? 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.

Detailed explanation-3: -The term byte was coined by Werner Buchholz in June 1956, during the early design phase for the IBM Stretch computer, which had addressing to the bit and variable field length (VFL) instructions with a byte size encoded in the instruction. It is a deliberate respelling of bite to avoid accidental mutation to bit.

Detailed explanation-4: -One byte is equivalent to eight bits. A bit is considered to be the smallest unit of data measurement.

Detailed explanation-5: -Bits and bytes These are binary digits, or bits for short. Single bits are too small to be much use, so they are grouped together into units of 8 bits. Each 8-bit unit is called a byte. A byte is the basic unit which is passed around the computer, often in groups.
