Computers use binary arithmetic $($i$.$e$.$ all numbers are composed of $1$s and Os$)$ to carry out their operations. Humans normally use decimal arithmetic $(0-9)$ and have symbolic meais of epresenting information $($eg$.$ the Latin Alphabet, or Chinese Characters$).($i$)$ Does this imply a fundamental difference between people and computers?$[3]$ii$)$ Briefly describe the difference between digital and analog systems$[4]$iii$)$ State any $2$ reasons for the widespread adoption and use of digital systems.$[2]$iv$)$ Give $3$ reasons why the $2\text{'}$s complement arithmetic is commonly used as compared to Other representations like the sign & magnitude & the one's compliment.$[3]$v$)$ State $2$ limitations of a truth table.$[2]$vi$)$ The state of a CPU register's contents is $1000101\mathrm{.}10001$ in fixed point representation.What are its contents if it represents a positive real number?$[4]$b$)$ What is the value of x after each of the following statements are encountered in acomputer program, if x $=1$ before the statement is reached?
