MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -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.

Detailed explanation-2: -A byte is the smallest unit of memory used in today’s computing. Bytes consist of eight bits, and a byte is used to encode a single number, letter, or symbol. Bytes’ use as such is a de facto international convention documented as ISO/IEC 2382-1:1993 by the International Organization for Standardization (ISO).

Detailed explanation-3: -A byte is a group of 8 bits. A bit is the most basic unit and can be either 1 or 0. A byte is not just 8 values between 0 and 1, but 256 (28) different combinations (rather permutations) ranging from 00000000 via e.g. 01010101 to 11111111 . Thus, one byte can represent a decimal number between 0(00) and 255.

Detailed explanation-4: -The correct answer is A bit. The smallest memory unit is known as a bit. The term “bit” refers to a binary digit.

Detailed explanation-5: -Answer and Explanation: One byte of data is also called an octet.
