Arrange the following according to their increasing storage capacity (i) Exabyte (ii) Zettabyte (iii) Petabyte (iv) Yottabyte Choose the correct answer from the following options:
(iii), (i), (ii), (iv)
Understanding Data Storage Capacity Units
Data storage capacity is measured in various units, which represent how much data can be stored on a device or system. These units are typically based on powers of 2 (specifically $2^{10}$ or 1024) in computing contexts, though powers of 10 (specifically $10^3$ or 1000) are also used for SI prefixes, especially in networking and for some storage vendors.
The question asks us to arrange the given storage capacity units according to their increasing storage capacity. Let's list the units provided:
- (i) Exabyte (EB)
- (ii) Zettabyte (ZB)
- (iii) Petabyte (PB)
- (iv) Yottabyte (YB)
Comparing Storage Capacity Units
To arrange these units in increasing order, we need to know their relative sizes. The common hierarchy of large data storage units is:
| Unit | Abbreviation | Approximate Size (relative to smaller unit) | Approximate Size (in bytes, using $1024^n$) |
|---|---|---|---|
| Kilobyte | KB | - | $1024^1$ bytes |
| Megabyte | MB | 1024 KB | $1024^2$ bytes |
| Gigabyte | GB | 1024 MB | $1024^3$ bytes |
| Terabyte | TB | 1024 GB | $1024^4$ bytes |
| Petabyte | PB | 1024 TB | $1024^5$ bytes |
| Exabyte | EB | 1024 PB | $1024^6$ bytes |
| Zettabyte | ZB | 1024 EB | $1024^7$ bytes |
| Yottabyte | YB | 1024 ZB | $1024^8$ bytes |
From the table, we can see the order of units from smallest to largest:
- Petabyte (PB)
- Exabyte (EB)
- Zettabyte (ZB)
- Yottabyte (YB)
Now let's map this order back to the Roman numerals given in the question:
- Petabyte (PB) corresponds to (iii)
- Exabyte (EB) corresponds to (i)
- Zettabyte (ZB) corresponds to (ii)
- Yottabyte (YB) corresponds to (iv)
Therefore, arranging the units in increasing storage capacity gives us the order:
(iii), (i), (ii), (iv)
Final Arrangement of Storage Units
Based on the increasing order of storage capacity, the correct sequence of the given units is Petabyte, Exabyte, Zettabyte, and Yottabyte. This corresponds to the option that lists the Roman numerals in the order (iii), (i), (ii), (iv).
Revision Table: Data Storage Units
| Rank (Increasing Size) | Unit Name | Abbreviation | Corresponds to |
|---|---|---|---|
| 1 | Petabyte | PB | (iii) |
| 2 | Exabyte | EB | (i) |
| 3 | Zettabyte | ZB | (ii) |
| 4 | Yottabyte | YB | (iv) |
Additional Information: Data Measurement Basics
Understanding data storage units is fundamental in computing. The smallest unit of data is a bit (binary digit), which can be either 0 or 1. Eight bits make a byte. Larger units are formed by multiplying by factors of 1024 (for computer memory and file sizes, often referred to as kibibyte, mebibyte, etc., though KB, MB, etc., are commonly used) or 1000 (for network speeds and sometimes storage advertising, following SI prefixes). The prefixes follow a pattern: Kilo, Mega, Giga, Tera, Peta, Exa, Zetta, Yotta. Each prefix represents a magnitude approximately 1000 or 1024 times larger than the previous one.
