Answer the following questions:
1. Why can cache improve performance?
Most today GPU and CPU have caches implemented
inside the chip. Cache can Improve the performance
because CPU tend to repeat the process over and over
again. If these processes are transfer to cache, they can
read the instruction much faster than not having cache
because cache act as a buffer between the data and CPU
to tell which program to process.
2. A workstation has a multi-socket motherboard but only
a single LGA 1150 socket is populated. The installed
CPU is a Xeon E3-1220. You have a Xeon E3-1231 CPU
in store that also uses the LGA 1150. Should this be
used to enable symmetric multiprocessing and
upgrade system performance?
This will not work because the CPU must be the same
because if the CPU are not exactly the same your system
will most likely not to pass the POST sequence. Even if
your system passes the boot sequence you PC might not
function properly.
3. You are specifying a computer for use as a software
development workstation. This will be required to run
multiple virtual machines (VMs). Can any x64compatible CPU with sufficient clock speed be used?
No. because you have to check the CPU OEM if it
supports virtual machines clock speed extension.
4. What must you check when inserting a PGA form
factor CPU?
This part is important because if you are not aligned pin 1
properly to the CPU socket when you locking the lever to
secure the CPU and placing in the wrong order you have
to buy a new CPU which is waste of money. To prevent
this from happening is check the pin 1 and the CPU arrow
icon to tell you which way to insert properly.
