Question

1-How many bytes are in a halfword?

		4
		2
		6
		8

2-Which of the following is NOT true of pseudo-instructions?

		They tend to be easier to understand than their machine instruction counterparts
		They map one-to-one to machine instructions
		They are “shortcuts” to common operations
		They may map to one or more machine instructions

3- What is the .data section of a MIPS program used for?

		To define variables to be used in the MIPS program
		It tells you that this MIPS program will work with data
		It’s where you place your actual MIPS instructions
		To instruct the MIPS compiler where to find main memory

4-Complex instruction set computer (CISC) is an instruction set that:

		Has more instructions, but is less verbose than RISC
		Is the basis for MIPS
		Is no longer in use, having been replaced largely by RISC
		Has fewer, but more complex instructions for the CPU to process

5- True or false: The difference between .ascii and .asciiz is that .asciiz character arrays (strings) are terminated with a “null” value whereas .ascii character arrays (strings) are not.

True

False

Answer 1

1-How many bytes are in a halfword?

Answer : - b) 2

(A word has 4 bytes and halfword has 2 bytes)

2-Which of the following is NOT true of pseudo-instructions?

Answer : - b)They map one-to-one to machine instructions

(Pseudo code is written in easier language that can be understood by a layman. Programmer scan use it for their reference in coding. It cannot be compiled.)

3- What is the .data section of a MIPS program used for?
Answer : - a) To define variables to be used in the MIPS program

4-Complex instruction set computer (CISC) is an instruction set that:

Answer :- d) Has fewer, but more complex instructions for the CPU to process

5- True or false: The difference between .ascii and .asciiz is that .asciiz character arrays (strings) are terminated with a “null” value whereas .ascii character arrays (strings) are not.

Answer :- ​​​​​​​ True
