1/10 Questions

Which of the following best represent kilobytes?
- 10^6
- 10^5
- 10^4
- 10^3

About This Quiz

Well, to buy one kilobyte nowadays is absurd and it's even impossible. This is as opposed to buying a yottabyte. That said, a kilobyte is like the far younger brother of terabytes and others. Nonetheless, we digress and we should instead go on with the quiz.

2.

How do you represent a kilobyte?
- KE
- KY
- KT
- K
Correct Answer

A. K

Explanation

The correct answer is "K". In data storage, a kilobyte is represented by the letter "K". It is a unit of digital information that is equal to 1024 bytes. This notation is commonly used in computer science and information technology to represent data sizes.

Technically, one kilobyte means
- 1020 bits
- 1020 bytes
- 1000 bits
- 1000 bytes
Correct Answer

A. 1000 bytes

Explanation

One kilobyte technically means 1000 bytes. In computer systems, storage capacity is typically measured in bytes, where each byte represents 8 bits. Therefore, one kilobyte is equal to 1000 bytes, not 1020 bits or 1020 bytes.

4.

Which of the following uses kilobytes extensively?
- Labels on hardisks
- Speed of yottabyte
- Calculating monthly internet traffic
- Main memory
Correct Answer

A. Main memory

Explanation

Main memory is the correct answer because kilobytes are commonly used to measure the capacity and size of computer memory. Main memory, also known as RAM (Random Access Memory), is used to store data and instructions that are currently being used by the computer's processor. Kilobytes are often used to quantify the amount of memory available in a computer system, as well as the size of individual files and programs that are loaded into memory. Therefore, main memory is the most appropriate option that extensively uses kilobytes.

1 MB in kilobytes is
- 1024^2
- 1020^2
- 1024^3
- 1020^4
Correct Answer

A. 1024^2

Explanation

The correct answer is 1024^2 because 1 megabyte (MB) is equal to 1024 kilobytes (KB). The exponent of 2 indicates that the conversion is being done from bytes to kilobytes. Therefore, multiplying 1024 by itself (1024^2) gives the correct conversion of 1 MB to kilobytes.

Which one doesn't use the binary interpretation (kilobytes)?
- AT&T
- Verizon
- Vodafone
- Orange
Correct Answer

A. Verizon

Explanation

Verizon is a telecommunications company that operates primarily in the United States. The question is asking which company does not use the binary interpretation for kilobytes. Kilobytes is a unit of digital information that is commonly used in computing. While AT&T, Vodafone, and Orange are all international telecommunications companies, Verizon is the only one that does not use the binary interpretation for kilobytes.

IEC used what to represent 1 kilobyte
- Kiibytes
- Kibibytes
- Kibytes
- Kiibibytes
Correct Answer

A. Kibibytes

Explanation

The correct answer is Kibibytes. The International Electrotechnical Commission (IEC) uses the term "Kibibytes" to represent 1 kilobyte. This is a binary unit of digital information storage, equal to 2^10 bytes. It is used to differentiate from the decimal-based kilobyte, which is equal to 10^3 bytes. The IEC introduced this term to provide a more precise and accurate representation of data storage.

Unformatted, the Shugart SA-400 5¹⁄₄-inch floppy disk held how much?
- 639K
- 256K
- 110K
- 128K
Correct Answer

A. 110K

Explanation

The Shugart SA-400 51⁄4-inch floppy disk held 110K of data.

Who describes kilobytes as 1000 bytes?
- The International Electronics Community
- The International Electronics Commission
- The International Electrotechnical Community
- The International Electrotechnical Commission
Correct Answer

A. The International Electrotechnical Commission

Explanation

The International Electrotechnical Commission (IEC) describes kilobytes as 1000 bytes. The IEC is an international standards organization that sets standards for electrical and electronic technologies. They have defined the prefixes for binary multiples, including kilo-, which represents 1000. This is in contrast to the International System of Units (SI), which defines kilo- as 1024. Therefore, the IEC's definition of kilobytes aligns with the decimal system commonly used in electronics and computer storage.

65,536 bytes of memory can be represented by
- 66K
- 65K
- 64K
- 63K
Correct Answer

A. 64K

Explanation

65,536 bytes is equal to 64 kilobytes (KB) because 1 kilobyte is equal to 1024 bytes. Therefore, the correct answer is 64K.
