Binary Code First Short Test

1. Which of the following is in correct order, from smallest to largest?

Byte, Kilobyte, Megabyte, Gigabyte, Terabyte

Megabyte, Kilobyte, Terabyte, Gigabyte, Byte

Byte, Kilobyte, Terabyte, Megabyte, Gigabyte

Terabyte, Gigabyte, Megabyte, Kilobyte, Byte

The correct order, from smallest to largest, is Byte, Kilobyte, Megabyte, Gigabyte, Terabyte. This is because each unit is a multiple of 1024 of the previous unit. A Kilobyte is 1024 Bytes, a Megabyte is 1024 Kilobytes, a Gigabyte is 1024 Megabytes, and a Terabyte is 1024 Gigabytes. Therefore, Byte is the smallest unit and Terabyte is the largest unit.

Explanation

The correct order, from smallest to largest, is Byte, Kilobyte, Megabyte, Gigabyte, Terabyte. This is because each unit is a multiple of 1024 of the previous unit. A Kilobyte is 1024 Bytes, a Megabyte is 1024 Kilobytes, a Gigabyte is 1024 Megabytes, and a Terabyte is 1024 Gigabytes. Therefore, Byte is the smallest unit and Terabyte is the largest unit.

2. In binary code, an 8-bit unit is called a ____________________.

In binary code, an 8-bit unit is called a byte. The term "byte" is used to refer to a sequence of 8 bits, which is the basic unit of storage in computer systems. It is commonly used to represent characters, numbers, and other data in computer programming. The lowercase "byte" is also accepted as a correct term for an 8-bit unit in binary code.

3. How many bits are in a byte?

1

8

10

None

A byte is a unit of digital information that consists of 8 bits. Each bit can represent either a 0 or a 1, allowing for a total of 256 possible combinations (2^8). Therefore, the correct answer is 8.
