Solution

## The correct option is B 9 parts of 1 byte eachIf nine bytes of data are required for processing, 9 parts of 1 byte eachs would an 8-bit data bus bring the data from memory. 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. The popularity of major commercial computing architectures has aided in the ubiquitous acceptance of the eight-bit size.Bit and byte:- A bit (short for binary digit) is the smallest unit of data in a computer. A bit has a single binary value, either 0 or 1. Although computers usually provide instructions that can test and manipulate bits, they generally are designed to store data and execute instructions in bit multiples called bytes Computer process data:- Data processing, Manipulation of data by a computer. It includes the conversion of raw data to machine-readable form, flow of data through the CPU and memory to output devices, and formatting or transformation of output. Any use of computers to perform defined operations on data can be included under data processing.
