Can you solve them step by step, to show me how you get the answer?
For ultra-high-speed data communication (Gigabyte data rate):
a. Parallel communication is practical and can be reliably constructed.
b. Parallel communication fails due to issues with wire insulation.
c. Serial communication in theory should always be faster than parallel communication at the same data rate.
d. None of the above.

The usage of Embedded C-Language to program microcontroller-based systems:
a. Allows the designer to develop products much faster and speed up the time to market for the final product.
b. Reduces the length of the produced assembly code after compilation.
c. Reduces the number of RAM variables needed for implementing any algorithm.
d. None of the above.
If register A has the value $55 stored in it and the carry flag is set, then the values in register A and in the "Z, N flags" after executing EORA204 are:
a. A = $FF, N-Flag = 0, Z-Flag = 0.
b. A = $00, N-Flag = 0, Z-Flag = 1.
c. A = $55, N-Flag = 0, Z-Flag = 0.
d. None of the above.
A DAC has a resolution of 8-bits, a reference voltage of VRL = 0V, and VRH = 10V. The analog output for an unsigned digital hex input of $20 will be approximately equal to:
a. 0.125V.
b. 0.250V.
c. 0.500V.
d. None of the above.
