Question 1. what are true about amicroprocessor and a microcontroller?

(a) Microprocessor contains the essential elements of acomputer, while microcontroller does not.

(b) Microcontroller contains the essential elements of acomputer, while microprocessor does not.

(c) A microprocessor contains the essential elements of acomputer, which are fabricated generally on a single IC.

(d) Microcontroller contains the elements of a microprocessor,but always adds extra components.

(e) A microcontroller usually contains digital input/output,serial ports, A to D converter, while microprocessors doesn't. (f)Both microcontroller and microprocessor usually contain digitalinput/output, serial ports, A to D converter.

Question 2. Awhat range of unsigned numbers canbe represented by a 16-bit ALU?

(a) 0 to 65536

(b) 1 to 65536

(c) 0 to 65535

(d) 1 to 65535

(e) None of (a) through (d) is the correct answer.

Question 3. what are true about the "bus" incontext of embedded systems?

(a) A bus is a set of wires or other interconnections. Ona printed circuit board, a bus can be just tracks on the board.

(b) A bus is dedicated to provide a general-purpose datainterchange between a set of sub-systems in a computer-basedsystem.

(c) A bus can only carry digital information in one designateddirection.

(d) The main examples for bus are the data bus and the addressbus.

(e) The data bus provides the means for data to be moved to orfrom different parts of the system, while the address bus providesthe means for the address of the data to be moved to or fromdifferent parts of the system.
