CSU CS250 FINAL EXAM (ALL QUIZZES AND MIDTERM
MATERIAL ONLY) WITH ALL CORRECT & 100% VERIFIED
ANSWERS|ALREADY GRADED A+
1. What is the result of 1 XOR 0? 1, because XOR (exclusive OR)
results in true only when inputs
ditter.
2. How does De Morgan's Law help in It allows the transformation of
Boolean logic? complex logical expressions by
changing ANDs to ORs and ORs to
ANDs, simplifying logic circuits.
3. What is the purpose of L1, L2, and L3 caches? To store frequently accessed
data closer
to the CPU to reduce access times,
with L1 being the fastest and
smallest, and L3 being slower but
larger.
4. What differentiates SRAM from SRAM (Static RAM) is used for
DRAM in terms of usage? cache memory due to its speed,
whereas DRAM (Dynamic RAM) is
used for main system memory due
to its density and cost-ef-
fectiveness.
5. What is the role of the Data Flip-Flop (DFF) in DFF is used to store a single
bit of data;
computer memory? it's a fundamental building block of digi-
tal circuits, ensuring data stability
across clock cycles.
6. Any Boolean function can be represented
by True a boolean expression containing
only Nand operators T/F

Proposals to represent decomal digits
with 10 distinct voltages were
dismissed because of the complexity
of the circuits
True
9. Binary representations (as opposed to
dec- imal) are used in computing
systems be- cause the arithmetic
operations need few- er components
and distinguishing between two
voltages is much more reliable False
10. Computers of the von Neumann
architec- ture can function without a
clock
11. The loop abstraction in programming allows
True us to design computations that are
much longer than the size of the
program
12. It is possible to design a program False
that in- spects another program if
any of the pro- grams loops are
infinite
13. a bitwise AND operation of two equal
length True binary representations can be
used to set a particular bit. T/F

be toggled by XOR-ing it with a 1. representation with
T/F itself always leads
