A series of computer data size units is given with one term missing. Choose the correct alternative from the given options that will complete the series in logical order: Bit, Byte, Kilobyte, Megabyte, ?

Introduction / Context:
This question presents a series based on standard units of digital information in computing. The terms Bit, Byte, Kilobyte and Megabyte follow the familiar hierarchy of storage sizes used in computer science. You are asked to select the next unit that logically continues this progression. Such series questions not only test general awareness of common technical terms but also your ability to recognize and extend an ordered scale.

Given Data / Assumptions:

• Given series: Bit, Byte, Kilobyte, Megabyte, ?
• Options: Binary, Gigabyte, Terabyte, Nanobyte.
• We assume the series describes increasing powers of two in common data size terminology used in everyday computing.
• The missing term should come immediately after Megabyte in the usual sequence of storage units.

Concept / Approach:
In computer science and everyday usage, data size units follow a well known ascending order: bit, byte, kilobyte, megabyte, gigabyte, terabyte, and so on. The series provided already follows this order from the smallest units to larger ones. Our task is to recall this standard hierarchy and pick the unit that directly follows megabyte. This is more a test of general knowledge of technology concepts than of complex logical manipulation.

Step-by-Step Solution:
Step 1: Recall the basic sequence of data units: Bit is the smallest basic unit, followed by Byte (typically 8 bits). Step 2: Above Byte, we have Kilobyte (approximately 10^3 bytes or 2^10 bytes in binary-based systems) and then Megabyte (approximately 10^6 bytes or 2^20 bytes). Step 3: The next commonly used unit in this sequence is Gigabyte, which is approximately 10^9 bytes or 2^30 bytes. Step 4: Terabyte comes after Gigabyte and represents an even larger unit, usually approximately 10^12 bytes. Step 5: Therefore, in the ascending order bit → byte → kilobyte → megabyte → gigabyte → terabyte, the term that immediately follows Megabyte is Gigabyte. Step 6: Among the given options, Gigabyte is present and matches this standard progression, so it must be the correct answer.

Verification / Alternative check:
A quick verification is to check whether any of the other options could reasonably follow Megabyte. Binary is not a storage size unit on this scale; it describes the numbering system used by computers rather than a quantity of data. Terabyte is indeed a valid data unit but normally comes after Gigabyte, making it too large to be the immediate next step. Nanobyte is not a standard commonly used unit in this context and does not fit the well known series. This leaves Gigabyte as the only option that accurately and directly follows Megabyte in the standard hierarchy of data sizes.

Why Other Options Are Wrong:
Binary refers to the base-2 numeral system and not to a specific position in the data size hierarchy. Terabyte is a valid larger unit, but it skips over Gigabyte and so does not represent the immediate next term after Megabyte. Nanobyte is not a standard data size unit in common usage and does not appear in the typical sequence of bit, byte, kilobyte, megabyte, gigabyte and terabyte. Because they do not fit the standard ordering directly after Megabyte, these options cannot be correct.

Common Pitfalls:
Some candidates might be attracted to Terabyte simply because it is a familiar large unit and appears alongside Megabyte in everyday discussions, especially when talking about storage devices. Others may be confused by Binary as a technical-sounding word. To avoid such mistakes, it is important to remember the widely accepted ordered list of data size units and to focus on the immediate successor in that sequence, rather than jumping ahead to a later, larger unit.

Final Answer:
Following the standard hierarchy of data units, the term that comes after Megabyte is Gigabyte. Therefore, Gigabyte is the correct completion of the series.
