How much is 1 byte equal to?
Correct Answer
C. 8 bits
Explanation
A byte is a unit of digital information that consists of 8 bits. Each bit represents a binary value of either 0 or 1. Therefore, 1 byte is equal to 8 bits.
2.
What does each keyboard character equals to?
Correct Answer
C. 1 byte
Explanation
Each keyboard character is equal to 1 byte. A byte is a unit of digital information that consists of 8 bits. Since a bit is the smallest unit of information in computing, 1 byte is the smallest unit that can represent a keyboard character. Therefore, each keyboard character is equivalent to 1 byte.
3.
Then how many bytes are there in 1000 keyboard characters?
Correct Answer
E. 1000 bytes
Explanation
The answer is 1000 bytes because each keyboard character is typically represented by 1 byte of data. Therefore, if there are 1000 keyboard characters, there would be 1000 bytes of data.
4.
1000 bytes = ? KB (kilobytes)
Correct Answer
B. 1 KB
Explanation
The correct answer is 1 KB because 1 kilobyte (KB) is equal to 1000 bytes.
5.
If 1000 kilobytes = 1 MB (megabyte) how many keyboard characters would this be?
Correct Answer
C. 1 million
Explanation
If 1000 kilobytes is equal to 1 megabyte, then it means that 1 megabyte is equivalent to 1 million bytes. Since each keyboard character is typically represented by 1 byte of data, 1 million keyboard characters would be equal to 1 megabyte.
6.
1000 megabytes = 1 GB (gigabyte) or ? characters
Correct Answer
D. 1 billion
7.
What is the name of the lowest 'data' level which is a series of 0s and 1s?
Correct Answer
B. Byte
Explanation
A byte is a unit of digital information that consists of a series of 0s and 1s. It is the smallest addressable unit of memory in most computer architectures and is commonly used to represent characters such as letters, numbers, and symbols. A bit, on the other hand, is the smallest unit of data in computing and can only represent a single 0 or 1. Therefore, a byte is the correct answer as it is the lowest level of data that can represent a series of 0s and 1s.
8.
Each number, letter and keyboard symbol is represented by a series of what?
Correct Answer
D. 8 bits
Explanation
Each number, letter, and keyboard symbol is represented by a series of 8 bits. A bit is the smallest unit of information in computing and can have a value of either 0 or 1. By combining 8 bits, which is called a byte, different combinations can be created to represent various characters and symbols. Therefore, the correct answer is 8 bits.
9.
Generally, people refer to 1000 bytes as a kilobyte, however in reality it is really ? bytes.
Correct Answer
C. 1024 bytes
Explanation
The correct answer is 1024 bytes. In computer storage, the binary system is used, where each byte consists of 8 bits. However, in the decimal system, 1 kilobyte is equal to 1000 bytes. This discrepancy between the binary and decimal systems has led to confusion, and many people refer to 1000 bytes as a kilobyte. However, in reality, a kilobyte is technically 1024 bytes, which is why the correct answer is 1024 bytes.

How much is the capacity of one floppy disk?
Correct Answer
D. 1.44 MB
Explanation
The capacity of one floppy disk is 1.44 MB. Floppy disks were a popular storage medium in the past, commonly used to store and transfer small amounts of data. The 1.44 MB capacity refers to the maximum amount of data that could be stored on a standard 3.5-inch floppy disk. This capacity was sufficient for storing documents, images, and small software programs. However, with the advancement of technology, floppy disks have become obsolete and are no longer widely used.
11.
How much is the capacity of CD ROM disks?
Correct Answer
B. 650 MB
Explanation
The capacity of CD ROM disks is 650 MB. This means that the disk can store up to 650 megabytes of data.
12.
DVD disks can hold between up to HOW MUCH of data ?
Correct Answer
E. 4.7 GB
Explanation
DVD disks can hold up to 4.7 GB of data. This is the correct answer because DVDs have a larger storage capacity compared to other options listed. 1 GB, 800 bits, and 8 bytes are all smaller units of data and cannot hold as much information as a DVD. While 4 GB is larger than the other options, 4.7 GB is the most accurate and specific answer as it reflects the typical storage capacity of a standard DVD.
