name two types of cpu manufacturers
|
intel, amd
|
|
|
name Intels current enthusiast, budget, mobile and server cpus
|
core i7/i5/i3, core 2 duo
pentium, celeron same as enthusiast but mobile, atom xeon/Itanium |
|
|
name AMD current ethusiast desktop, budget desktop, mobile and server cpus
|
phenom II, a-series, phenom, and athlon x2
sempron, Athlon II turion opteron |
|
|
saving energy by making the CPU run more slowly when demand is light is called?
|
throttling
|
|
|
in modern CPUs the speed and multiplier are set how?
|
automatically through a function called CPU identifier
|
CPUID
|
|
Theoretically, a 64 bit address bus can address how much RAM?
|
16 EB of RAM
|
|
|
what is virtualization?
|
running more than one operating system at a time
|
|
|
when a multicore CPU processes more than one thread
|
parallel execution
|
|
|
what are the four steps in pipelining?
|
fetch: get the data from the EDB
decode: figure out what type of command needs to be executed execute: perform the calculation write: send the data back onto the EDB |
|
|
what are the two types circuitry that handle the calculations in the CPU?
|
arthmetic logic unit (ALU) basic numbers
floating point unit(FPU) complex numbers |
using a single pipeline the FPU and ALU are done at the execution stage
|
|
because the CPU runs faster, the RAM can supply it code you'll always get pipeline stalls called?
|
wait states
|
|
|
what is static RAM
|
it was built into CPUs to reduce wait states.
|
it preloaded as many instructions as possible and keeps copies of already run instructions and data in case the CPU--this is called cache
|
|
what are the three types of caches that were added directly to the motherboard?
|
L1 smallest and fastest
L2 bigger and smaller than L1 L3 biggest and slowest |
|
|
wires that connect the CPU to the main system RAM
|
frontside bus
|
runs at 66-133 MHz
|
|
set of wires that connects the CPU to L2
|
backside bus
|
first appeared in Pentium pro
|
|
what is hyper-threading/ simultaneous multi-threading?
|
splits one CPU into two
|
it doesn't double the processing. it only enhances the CPUs efficiency
|
|
combining two CPUs into a single-chip
|
dual-core architecture
|
it has two sets of pipelines
|
|
using 2 or more execution cores on one CPU die to divide up work independently of the OS
|
multicore processing
|
|
|
what is IMC
|
integrated memory controller. it optimizes the flow of information into and out the CPU.
|
|
|
video processor that helps the CPU by taking over all of the 3-D rendering duties
|
graphics processing unit (GPU)
|
|
|
Intel-based LGA 775 socket's CPUs
|
Pentium 4, Celeron,
Pentium 4 extreme edition, core 2 duo, core 2 quad, xeon |
|
|
Intel-based LGA 1155/1156 sockets CPUs
|
Core i3/i5/i7, Pentium, celeron, Xeon
|
|
|
intel-based sockets LGA 1366 CPUs
|
Core i7, xeon, Celeron
|
|
|
socket for CPUs that enables insertion of a chip without the need to apply pressure
|
Zero insertion force socket
|
the chip drops effortlessly into the socket's holes and a small lever locks it in.
|
|
name four types of CPU cooling devices
|
OEM CPU coolers
specialized CPU coolers liquid cooling thermal compound |
|
|
intentionally running your systems at clock speeds higher than the CPU was rated
|
overclocking
|
it has been known to destroy conputers
|
|
how do u overclock?
|
1. through jumpers, CMOs settings or software configuration you would increase the bus speed
2. increase the voltage going into the CPU |
|
|
if your computer is continuously rebooting or wont start up, what kind of problem do u have?
|
CPU cooling problem
|
open your case up and make sure the heatsink is properly seated and all fans are running.
