Which of the following memory units has the largest storage capacity ?

The correct answer is 2) 1 TB.

Key Points

• 1 TB (Terabyte) is the largest memory unit among the given options, equivalent to 1024 GB.
• 1 TB is significantly larger than other units such as 1 GB (Gigabyte), 1 MB (Megabyte), and 1 KB (Kilobyte).
• Storage capacity increases exponentially as we move up in the hierarchy: KB → MB → GB → TB.
• Terabytes are widely used in modern computing for storing massive amounts of data, such as in hard drives, cloud storage, and data centers.
• For reference, a typical hard drive for personal use today often comes with storage capacity in the range of 1 TB to 4 TB.

Additional Information

• Memory Unit Hierarchy:
  • 1 KB (Kilobyte) = 1024 Bytes.
  • 1 MB (Megabyte) = 1024 KB.
  • 1 GB (Gigabyte) = 1024 MB.
  • 1 TB (Terabyte) = 1024 GB.
• Practical Usage of Memory Units:
  • KB and MB are commonly used for text files, images, and small applications.
  • GB is used for larger files like videos, games, and software applications.
  • TB is used for massive storage needs, such as backing up entire systems, video editing, and enterprise-level databases.
• Advancements in Storage Technology:
  • Modern storage devices like SSDs (Solid-State Drives) and HDDs (Hard Disk Drives) are now available in TB capacities.
  • Cloud storage providers, such as Google Drive, Amazon S3, and Dropbox, offer scalable storage options up to several terabytes for individuals and businesses.
• Exabyte and Beyond:
  • After Terabytes, the next unit is Petabyte (PB), followed by Exabyte (EB), Zettabyte (ZB), and Yottabyte (YB).
  • These units are used in large-scale data centers and for global data storage systems.
