Arrange the following units of memory in ascending order:

A. Megabyte

B. Gigabyte

C. Kilobyte

D. Petabyte

E. Terabyte

Choose the most appropriate answer from the options given below:

The correct answer is Option 3.

Key Points

• The correct order of memory units from smallest to largest is Kilobyte, Megabyte, Gigabyte, Terabyte, and Petabyte.
• 1 Kilobyte (KB) equals 1,024 bytes.
• 1 Megabyte (MB) equals 1,024 Kilobytes.
• 1 Gigabyte (GB) equals 1,024 Megabytes.
• 1 Terabyte (TB) equals 1,024 Gigabytes.
• 1 Petabyte (PB) equals 1,024 Terabytes.

Additional Information

• Memory Hierarchy
  • Memory units are organized in a hierarchy based on size and speed. At the lowest level are registers, followed by cache memory, main memory (RAM), secondary storage (hard drives and SSDs), and tertiary storage (tape drives).
  • Each level of memory serves a specific purpose and is used to optimize performance and cost in computer systems.
• Bit and Byte
  • A bit is the smallest unit of data in a computer and can have a value of 0 or 1.
  • A byte consists of 8 bits and is the basic unit of information storage in digital computing.
• Data Measurement Units
  • Data is measured in various units such as bits, bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and petabytes (PB).
  • These units are used to quantify digital information and storage capacity in computing devices.
• Storage Devices
  • Different storage devices are used to store data, including hard disk drives (HDD), solid-state drives (SSD), USB flash drives, and optical discs like CDs and DVDs.
  • The choice of storage device depends on factors such as storage capacity, speed, and cost.
