Understanding Memory Unit Sizes
Memory units measure digital information storage capacity. Common units include Kilobytes (KB), Megabytes (MB), Gigabytes (GB), Terabytes (TB), and Petabytes (PB). These units follow a hierarchical structure where each larger unit represents a significantly greater amount of data.
Memory Unit Hierarchy
The standard relationship between these units is based on powers of 1024:
- 1 Megabyte (MB) is approximately $10^6$ Bytes (1024 KB)
- 1 Gigabyte (GB) is approximately $10^9$ Bytes (1024 MB)
- 1 Terabyte (TB) is approximately $10^{12}$ Bytes (1024 GB)
- 1 Petabyte (PB) is approximately $10^{15}$ Bytes (1024 TB)
Comparing Given Options
Comparing the units provided in the question:
| Unit | Approximate Size (in Bytes) |
| Megabyte (MB) | $10^6$ |
| Gigabyte (GB) | $10^9$ |
| Terabyte (TB) | $10^{12}$ |
| Petabyte (PB) | $10^{15}$ |
Conclusion
From the comparison, Petabyte (PB) represents the largest amount of data storage among the given options (Megabyte, Gigabyte, Terabyte, and Petabyte).

______ is the fastest to read from and write to than the other kinds of storage in a computer.
Suppose that the register A and register K have the bit configuration. Only the three leftmost bits of A are compared with memory words because K has 1's in these positions. Because of its organization, this type of memory is uniquely suited to parallel searches by data association. This type of memory is known as
