Seminar 4 - Exercises #1. How many cells can be in a computer’s main memory if each cell’s address can be represented by two hexadecimal digits? What if four hexadecimal digits are used? Explain your answer. Answer: Hexadecimal digits is a base 16 number system and it ranges between 0 and F i.e. 0 - 9 and A - F (10 -15). (Table 1 below shows binary‚ decimal and hexadecimal representation). Two hexadecimal digits will be between 00 and FF and this will make up to 256 cells i.e. 0 – 255 (16

MICROCONTROLLERS A microcontroller (sometimes abbreviated µC‚ MCU) is a small computer with similar components as a standard personal computer only integrated on to a single chip and usually dedicated to a single task. The fundamental components include a processor core (C.P.U)‚ memory‚ system clock and programmable input/output peripherals. Microcontrollers are designed for embedded applications‚ in contrast to the microprocessors used in personal computers or other general purpose applications
