a.

Translate the first instruction to English:

Explanation of Solution

Memory cell:

It is the smallest part of the computer memory that can be changed with a single operation. It allows storage of both data and program.

Instruction:

The machine instruction is a sequence of $0\text{s}$ and $1\text{s}$ that describes the physical operation in the computer.

Bit pattern:

A bit pattern is the sequence of bits in a memory which are used to contrast them with some higher level interpretation of bits.

Address content:

• The bit pattern for memory cell at address $00$ is $0126$.
• The bit pattern for memory cell at address $01$ is $0255$

b.

The bit pattern in register when machine halts:

Explanation of Solution

Halting:

During halting, no machine can decide answers correctly. This means that it is not able to terminate and produce answers correctly.

As the first instruction is completed or executed, the program counter goes through the next address that is $02$
