CSE 230 EXAM 1 2025 QUESTIONS
AND ANSWERS
Computer Architecture - ANSWER-Encompasses those aspects of a computing
system that are visible or important to the programmer
Instruction set - ANSWER-Assembly language instructions that can be executed
by the processor
CPU registers - ANSWER-Storage within the processor; how many, names, sizes,
usage limitations
Data representation - ANSWER-Signed and unsigned integers, characters, real
numbers, etc; sizes
I/O - ANSWER-Memory mapped (devices accessed by reading and writing
memory), ports (special instructions)
Memory - ANSWER-How much, address space, segmentation, cache levels
Instruction addressing modes - ANSWER-Where does data come from and where
does it go when an instruction is executed

, Instruction Set Architecture (ISA) - ANSWER-a specification of the underlying
computer architecture. Every type of microprocessor has its own ISA
Computer Organization - ANSWER-Encompasses how to design and build the
hardware to implement the architecture (architecture comes first)
machine language - ANSWER-all instructions and data are encoded in binary
Assembler - ANSWER-Symbolic representation of instructions that maps directly
to the architecture and machine language of the processor
mnemonics - ANSWER-represents machine language instructions
situations that warrant assembly language - ANSWER-trying to optimize a piece of
code for speed or space purposes
what does processor executes? - ANSWER-binary machine language instructions
in machine language, how are all instructions and data encoded - ANSWER-in
binary
why do we prefer to use HLL - ANSWER-the programmer normally does not
need to understand the underlying instruction set architecture and HLL's are
generally hardware-independent
Storage devices - ANSWER-DRAM memory, hard drive, SSD
Datapath - ANSWER-Processor hardware components that manipulate bits to
execute instructions.
