Question

1. which unit of storage or memory is the biggest?

gigabytes
megabytes
terabytes
kilobytes

1. what is the heart of the computer through which all data flows?

motherboard
rom, or read - only memory
cpu, or central processing unit
ram, or random access memory

Explanation:

For question 5:

• Kilobyte (\(1\) KB \( = 2^{10}\) bytes)
• Megabyte (\(1\) MB \(=2^{10}\) KB \( = 2^{20}\) bytes)
• Gigabyte (\(1\) GB \(=2^{10}\) MB \(=2^{30}\) bytes)
• Terabyte (\(1\) TB \(=2^{10}\) GB \(=2^{40}\) bytes)

Since \(2^{40}>2^{30}>2^{20}>2^{10}\), terabytes are the largest among the given options.

For question 6:

• The motherboard is the main circuit board that connects components.
• ROM stores firmware.
• RAM is volatile memory for temporary data storage.
• The CPU (central processing unit) is the “heart” as it processes all data and controls the computer's operations, with data flowing through it for processing.

Answer:

1. terabytes
2. CPU, or central processing unit
