How many Nibbles make up a single Byte?
Correct Answer: D. 2
Since a byte has 8 bits and a nibble has 4 bits, two nibbles fit into one byte. This division allows for the easy representation of two hexadecimal characters in one byte. It is a fundamental concept in low-level data processing.
Which unit is equivalent to 1024 Petabytes?
Correct Answer: A. Exabyte
The Exabyte is the next unit after the Petabyte in the measurement scale. It represents a massive volume of data equivalent to roughly one quintillion bytes. Global internet traffic is often measured in units of Exabytes.
What is the full form of the unit 'PB' in computer storage?
Correct Answer: C. Petabyte
PB stands for Petabyte, which is a common unit for high-capacity storage servers. It follows the Terabyte (TB) in the standard order of magnitude. Scientific research data like that from telescopes often reaches the PB scale.
Which of the following is the largest unit of memory storage among the choices?
Correct Answer: C. Zettabyte
Zettabyte is significantly larger than Terabyte, Petabyte, and Exabyte. It is equal to 1024 Exabytes or approximately one sextillion bytes. It is used to describe the total amount of data existing on the entire internet.
The value of 1024 Zettabytes is equal to which unit?
Correct Answer: C. Yottabyte
Yottabyte is currently one of the highest units defined by the International System of Units for data. It is approximately equal to a septillion bytes. As digital data grows, even larger unofficial units like Geopbyte are discussed.
A binary digit '0' or '1' is the definition of which term?
Correct Answer: D. Bit
A bit represents the most basic choice between two mutually exclusive states. Computers use high and low voltages to represent these 1s and 0s. All complex data like photos and videos are eventually stored as long strings of bits.
If a computer has 4 Gigabytes of RAM, how many Megabytes of RAM does it have?
Correct Answer: A. 4096 MB
By multiplying 4 by 1024, we get the exact value of 4096 Megabytes. This calculation follows the binary logic used in computer hardware. This extra 24 MB per GB is significant for system memory addressing.
Which unit is 1024 times larger than a Megabyte?
Correct Answer: C. Gigabyte
The Gigabyte is the standard unit that follows the Megabyte in the hierarchy. It is commonly abbreviated as GB and used for storage drives. One Gigabyte contains exactly 1,073,741,824 bytes.
Which is the smallest unit among the following?
Correct Answer: D. Kilobyte
The Kilobyte is the smallest of these four units, representing about 1000 characters of text. Megabyte is 1024 times larger than a Kilobyte. In modern systems, Kilobytes are used for small configuration files or icons.
A collection of 8 bits is called a?
Correct Answer: C. Byte
Eight bits are combined to create a single byte. This grouping is the fundamental building block for representing computer data. It is the most common unit used to describe storage capacities and file sizes.
