Computer Memory | MCQs

Explanation

KB stands for Kilobyte

MB stands for Megabyte

GB stands for Gigabyte

TB stands for Terabyte

Explanation

1000 million bytes is equal to 1 billion bytes, which is equivalent to 1 gigabyte (GB).

To break it down:

1 million bytes = 1 megabyte (MB)

1000 million bytes = 1000 megabytes (MB)

1000 megabytes (MB) = 1 gigabyte (GB)

Explanation
