Explain the difference between a bit, a nibble, and a byte.

A bit is 1 binary digit, a nibble is 4 bits, and a byte is 8 bits.

A bit is 8 binary digits, a nibble is 1 bit, and a byte is 4 bits.

A bit is 4 binary digits, a nibble is 8 bits, and a byte is 1 bit.

A bit is 1 binary digit, a nibble is 8 bits, and a byte is 4 bits.

What is the correct order of data units from smallest to largest?

A) byte, kilobyte, megabyte, gigabyte, terabyte, petabyte

B) petabyte, terabyte, gigabyte, megabyte, kilobyte, byte

C) kilobyte, byte, megabyte, gigabyte, terabyte, petabyte

D) byte, megabyte, kilobyte, gigabyte, terabyte, petabyte

Understanding how text, images, and sound are stored in binary format is important because:

it allows for efficient data processing and storage.

it makes data retrieval slower.

it is only relevant for computer scientists.

In binary, what is the binary representation of the denary number 3?

The binary representation of the denary number 3 is 11.

The binary representation of the denary number 3 is 10.

The binary representation of the denary number 3 is 01.

The binary representation of the denary number 3 is 111.

Computers use binary instead of denary because:

binary is more efficient for processing

binary is easier for humans to understand

denary is not supported by modern computers

binary allows for more complex calculations

Explain how to perform binary addition as described in the image.

Binary addition involves adding bits from right to left, carrying over any value greater than 1.

Binary addition is performed by subtracting bits from left to right.

Binary addition is similar to decimal addition but without carrying over.

Binary addition is performed by multiplying bits.

Why is it difficult for humans to use binary representation for large groups of binary digits?

Because binary numbers are too long and complex for humans to easily interpret.

Because binary representation is not used in modern computing.

Because humans are not trained to understand binary.

Because binary digits are not used in mathematics.

What is the first step in converting a hexadecimal number to denary using Method 1?

Identify the hexadecimal number

Convert each digit to its decimal equivalent

Multiply each digit by its positional value

Add all the decimal values together
