A kilobyte is often compared to half a page of typed text. What does a Megabyte roughly represent?
Correct Answer: D. A thick book
The correct answer is 'A thick book'. One Megabyte can store roughly 500 pages of text or a medium-sized novel. It is a million-fold increase over a single character. This comparison helps visualize data volume for non-technical users.
Which memory unit is typically used to measure the capacity of a smartphone's internal storage?
Correct Answer: D. Gigabytes (GB)
The correct answer is 'Gigabytes (GB)'. Gigabyte is the standard unit for consumer electronic storage devices like phones and tablets. Common capacities include 64 GB, 128 GB, and 256 GB. It provides a convenient scale for storing apps, photos, and videos.
Which unit comes immediately after Zettabyte in the increasing order of memory units?
Correct Answer: D. Yottabyte
The Yottabyte is the largest officially recognized SI unit for data measurement. It is equal to 1024 Zettabytes. As global data creation accelerates, these massive units are becoming more relevant in cloud computing.
How many Kilobytes are in 2 Megabytes?
Correct Answer: A. 2048 KB
Since one Megabyte is 1024 Kilobytes, two Megabytes equal 2048 Kilobytes. This follows the binary multiplication rule of 2 x 1024. Most digital images today are between 2 MB and 5 MB in size.
Which of the following is equal to 8 bits?
Correct Answer: B. 1 byte
One byte is the basic grouping of eight bits used in digital systems. It is the most frequent term used in computing to quantify data. A single byte can store a whole number ranging from 0 to 255.
The term 'Bit' is short for which phrase?
Correct Answer: B. Binary Digit
Binary Digit refers to the base-2 numbering system used by computers. It consists of only two digits: 0 and 1. This term was first coined by John Tukey in 1947.
Which unit is used to measure RAM speed, though it is a unit of frequency?
Correct Answer: B. Megahertz
Megahertz (MHz) measures the clock speed or frequency of the memory modules. While not a unit of capacity, it directly affects how fast data can be read from memory. Modern RAM often uses Megatransfers per second (MT/s) for greater accuracy.
What is the ratio of bits in a Byte to bits in a Nibble?
Correct Answer: A. 2:1
A byte has 8 bits and a nibble has 4 bits, making the ratio 8:4, which simplifies to 2:1. This means a byte is exactly twice the size of a nibble. This simple mathematical relationship is fundamental to binary arithmetic.
Which memory unit is mostly used to measure the size of small text files?
Correct Answer: C. Kilobytes
Kilobytes are appropriate for measuring small files like basic text documents or simple icons. One KB is 1024 bytes, which is enough to store about 170 words. In the era of high-speed internet, KB-sized files load almost instantly.
How many Megabytes are in 1 Terabyte?
Correct Answer: C. 1,048,576 MB
Multiplying 1024 (MB in a GB) by 1024 (GB in a TB) gives 1,048,576 MB. This shows the massive scale difference between Megabytes and Terabytes. It highlights why we need higher-level units for modern storage drives.
