Which of the following is an example of unguided transmission media? A microcontroller differs from a microprocessor because it... Binary number 1010112 is equal to

Here are the answers to the remaining questions:

8. Which of the following is an example of unguided transmission media?

   • D. Radio waves Unguided transmission media, also known as wireless media, transmit data through the air without a physical conductor. Radio waves are a prime example of this. Twisted pair, fibre optic, and coaxial cables are all guided media.

9. A microcontroller differs from a microprocessor because it

   • A. includes CPU, memory and I/O on one chip A microcontroller is a compact integrated circuit that contains a processor core (CPU), memory (RAM and ROM/flash), and programmable input/output peripherals all on a single chip, making it a self-contained system. A microprocessor typically only contains the CPU and requires external components for memory and I/O.

10. Binary number $101011_2$ is equal to To convert the binary number $101011_2$ to decimal, we multiply each digit by the corresponding power of 2:

    $$1 \times 2^5 + 0 \times 2^4 + 1 \times 2^3 + 0 \times 2^2 + 1 \times 2^1 + 1 \times 2^0$$ $$= 1 \times 32 + 0 \times 16 + 1 \times 8 + 0 \times 4 + 1 \times 2 + 1 \times 1$$ $$= 32 + 0 + 8 + 0 + 2 + 1$$ $$= 43$$
    • B. 43
