This sequence is (a)   bytes long: 11000011 11110011 11111011 10000001

• 32
• 2
• 8
• 4

Answer explanation

The question asks for the length of the given binary sequence in bytes. Each byte consists of 8 bits. The sequence has 4 groups of 8 bits each, which means it is 4 bytes long. Therefore, the correct answer is 4.

Which of these values can be stored as a single bit?

• 4

• 0, 1, 0, 0

• 11

• 0

Answer explanation

A single bit can store only two values: 0 or 1. In the given question, the correct choice is 0, as it is one of the two possible values that can be represented by a single bit. The other options involve multiple bits or values outside the binary range.

What is a minimum number for bits that can represent this setting page in this image?

(a)  

Answer explanation

The image of the setting page is not provided, but since there is only one option available (2 bits), it is the minimum number of bits that can represent the setting page in the image. Two bits can represent four different states, which might be sufficient for a simple setting page.

From this alarm clock, what information could be listed using only one bit of information? Select ALL that are correct

• Month (1-12)

• Day (1-31)

• Temp (F or C)

• Hour Type (AM or PM)

• Minute (1 - 59)

Answer explanation

One bit of information can represent two states (0 or 1). The only option that can be represented with two states is the Hour Type (AM or PM). Other options require more than one bit to represent their range of values.

Which of these best describes what a binary digit can store?

• A binary digit can store a series of two single-digit values, such as [4, 8].

• A binary digit can store one of two values, 0 or 1.

• A binary digit can store one of the values from 0 - 9.

• A binary digit can store a series of two 0/1 values, such as [1, 1].

Answer explanation

The question asks about the storage capacity of a binary digit. The correct answer is that a binary digit, also known as a 'bit', can store one of two values, either 0 or 1. This is the fundamental principle of binary code, which is the basis of all digital computing.

Which of the following is a byte of information?

• 10

• 1001

• 0

• 01100111

• 1010110010

Answer explanation

The question asks for a byte of information. A byte is a unit of digital information that consists of 8 bits. Each bit can be either 0 or 1. Therefore, the correct answer is '01100111', as it is the only option that consists of exactly 8 bits.

There are (a)   bits in 3 bytes.

• 32
• 24
• 8
• 1

Answer explanation

The question asks about the number of bits in 3 bytes. In computing, 1 byte is equal to 8 bits. Therefore, 3 bytes would be equal to 3*8 = 24 bits. Hence, the correct answer is 24.

Where would the spaces go in the following string?

010101011101001011000000

• 010101011101 001011000000

• 0101 0101 1101 0010 1100 0000

• 01 01 01 01 11 01 00 10 11 00 00 00

• 01010101 11010010 11000000

Answer explanation

The correct answer is '01010101 11010010 11000000'. This is because the spaces are placed after every 8 digits in the given string. This pattern is only followed in this option, making it the correct choice.

A computer is updating its clock but runs into an error. So instead of decimal characters for the day of the month, it gives you the binary characters: 11011 What is that decimal for the day date?

(a)  

Answer explanation

The binary number 11011 is equivalent to the decimal number 27. In binary, each digit represents a power of 2, starting from the rightmost digit (2^0) and moving left (2^1, 2^2, etc.). If you add up the values of the positions where there are 1s (2^0 + 2^1 + 2^3 + 2^4), you get 27. Therefore, the day date is 27.

Reorder the following binary digits from smallest (Left) to largest (Right)

• 0101

• 0110

• 0011

• 1010
