What is the smallest unit of data in a computer?

• Byte

• Bit

• Kilobyte

• Megabyte

Answer explanation

The smallest unit of data in a computer is a Bit, which represents a single binary digit (0 or 1). It is the basic building block for all digital data storage and processing.

How many bits are there in a byte?

• 4

• 8

• 16

• 32

Answer explanation

A byte consists of 8 bits. Therefore, there are 8 bits in a byte, making the correct answer choice 8.

What base does the binary system use?

• Base 10

• Base 2

• Base 8

• Base 16

Answer explanation

The binary system uses Base 2, where each digit can only be 0 or 1, representing powers of 2. It is the foundation of all digital systems.

How do you convert bits to bytes?

• Multiply the number of bits by 8

• Divide the number of bits by 8

• Multiply the number of bytes by 8

• Divide the number of bytes by 8

Answer explanation

To convert bits to bytes, you need to divide the number of bits by 8. This is because there are 8 bits in 1 byte.

Which of the following is an example of a byte?

• 11000001

• 101

• 1001

• 111

Answer explanation

The correct choice for a byte is 11000001, as it consists of 8 bits which is the standard size for a byte in binary representation.

What digits does the decimal system use?

• 0-1

• 0-9

• 0-8

• 0-7

Answer explanation

The decimal system uses digits from 0 to 9, allowing for a total of 10 possible digits in the system.

In the binary system, what is the decimal equivalent of 1000?

• 4

• 6

• 8

• 10

Answer explanation

In the binary system, 1000 represents the decimal number 8. Each digit in binary represents a power of 2, so 1*2^3 = 8.
