Q$\mathrm{.}1.$ Answer the following questions:

$[10$M: $5+5$

a$)$ From the following random word$-$mix, pick sets of words, with each set having $3$ unique

words. For each set of words, make a technically correct and meaningful statement.

You need to make five statements using five sets of words.

$($Example: the following statement makes use of the three unique words: Instruction,

Fetch and Memory. "The Instruction cycle starts with the Fetch phase, which obtains

from Memory the next instruction to be processed"$).$

Instruction, Fetch, Memory, Human, Control, Combinational, Store, Program Counter,

Output, Indirect, Opcode, Organization, Interrupt, Execute, Branch, Addressing,

Operands, Iterative, Trap, Decode, Registers, DMA, Processing Unit, Architecture,

Machine, Circuit, Condition, Conditional, Logic, Operate, Format, Data, Jump,

Immediate, Offset, Instruction Register, Input, Load, Routine, Sub$-$routine, Programmed,

Asynchronous, Timing, Communication, Status, Sequential, Bus, MAR, MDR$.$

b$)$ Consider a decimal number $-60.$ Find out the equivalent representation and number of

digits needed to represent the decimal number in binary, octal, and hexadecimal

representations suitable for modern computers. For example, representing the decimal

number $13$ requires $5$ digits in binary $(01101),$ two digits in octal $(15),$ and two digits in

hexadecimal $($OD$).$ Note: Answers written without steps will not be awarded any marks.
