Binary Numbers Practice Test

Binary Basics passage: Binary is a base-2 system using only 0 and 1, while decimal is base-10 using digits 0–9. For instance, decimal 6 is binary 110. Computers use binary states (off/on) as bits, and group bits into bytes to store and process data. According to the text, How does binary differ from the decimal system?

Binary in Computing passage: Computers represent information with bits that can be 0 or 1, like switches that are off or on. Eight bits make a byte, and bytes can encode numbers and characters. For example, decimal 10 is binary 1010. This base-2 structure makes storage and processing reliable in hardware. Based on the passage, Why are binary numbers used in computer systems?
