The state of existence of something in transition being developed, or
manifested, refers to which computer parameter? - correct answer ✔Latency
Which of the following is not a computer system performance parameter? -
correct answer ✔Transmission
Benchmarks are _____. - correct answer ✔reference points against which
the computer system's parameters are measured for performance
One of the main challenges of benchmarking for computer performance
evaluation is _____. - correct answer ✔constant changes that come with
technology advancements
Computer performance evaluation is defined as _____. - correct answer
✔the process by which a computer system's resources and output are
assessed to determine whether the system is performing at its optimal level
What is Spike testing? - correct answer ✔The server is subject to a sudden
extreme increase / spike in load within a short period of time
Which of the following is NOT an industry standard for computer bench
marking? - correct answer ✔Server-client benchmarks
What is computer performance and how does it relate to bench marking? -
correct answer ✔Computer performance is the speed and effectiveness of
,the system. These parameters are measured and compared to reference
points called benchmarks to evaluate the system.
Give a reason why web server benchmark results may not be a true reflection
of the web server being analysed? - correct answer ✔Because bench
marking tests carried out are client simulations in a small LAN setup without
real world interference.
In sub system-level bench-marking, the main characteristics of subsystems
that are tested against various bench-marking parameters is _____. - correct
answer ✔their READ/Write operations
Why do we not rely only on clock speed frequencies as a way to measure
computer performance today? - correct answer ✔All of these answers are
correct.
In the earlier days of computing, what two deciding factors played the most
significant roles in selecting a processor for performance reasons? - correct
answer ✔Clock speed and core count.
Which of the following numbers is an example of a floating point number? -
correct answer ✔0.001
What is a big reason why we need a unified method for comparing different
CPU ecosystems? - correct answer ✔All of these answers are correct.
Measuring MIPs is not very useful since there is no real way to gauge system
performance. MIP measurement is useful to business however, for which
important function? - correct answer ✔It allows business owners to know the
cost of computing.
,Disk defragmentation helps improve disk performance by _____ - correct
answer ✔compacting non-contiguous unused spaces and programs into
more contiguous elements
Which of the following parameters indicates the time it takes the magnetic
head to locate unused space on a platter? - correct answer ✔Write Seek
time
The performance of hard disks are an important factor in the overall
performance of a computer system because _____ - correct answer ✔they
hold all software and applications used to run the computer system. The
performance of the drive directly affect the performance of the system.
Which of the following statement is true? - correct answer ✔A 3.5 inch platter

platter with a spindle spin of 10,000 rpms.
Drive form factor is _____. - correct answer ✔a drive specification that
indicates the capacity of a drive and the number of platters encased
In the LINPACK benchmark, what does Fortran n=100 benchmark measure? -
correct answer ✔A fortran program run without any modifications

rate of computation for every watt of power used
What is the TOP500 list? - correct answer ✔List of supercomputers ranked
by the LINPACK benchmark
Which of the following is TRUE of the Z3 developed by Konrad Zuse from
1935 to 1941? - correct answer ✔It was the first working, programmable and
fully automatic digital computer
The first device that could be called a 'personal computer' was the _____,
