What is “binary code”?
a) A system of representing data using only 0s and 1s
b) A computer programming language
c) A type of security algorithm
d) A tool for managing databases
Answer:
a) A system of representing data using only 0s and 1s
Explanation:
Binary code is the fundamental language of computers, consisting of only two symbols: 0 and 1. It is a base-2 numeral system used to represent data in computer systems, where each bit (binary digit) corresponds to either a 0 or 1.
All data processed by a computer, including text, images, and commands, is ultimately translated into binary code. For example, the letter ‘A’ in binary is represented as 01000001. The combination of bits forms meaningful instructions for the computer to execute.
Understanding binary code is essential for computer science, as it represents the most basic form of data that a computer can process. All higher-level programming languages and software are eventually broken down into binary for the computer to execute.
