Name the five basic processor components |
Input/output component, arithmetic logic units, registers, internal memory caches, control unit |
|
|
Processor frequency |
The speed at which processor operates internally |
|
|
Multiplier |
Factor multiplied against system bus frequency (determines processor frequency). System bus frequency x multiple = processor frequency |
|
|
Machine language |
The only language a computer can understand directly. Each type of computer has a unique machine language which is stored in true binary format and tell the CPU what to do. |
|
|
What language is the only language a CPU can understand? |
Machine language |
|
|
Instruction set |
The collection of machine instructions that a CPU can process. There is CISC and RISC. |
|
|
What is CISC? |
Complex Instruction Set Computing. The instructions vary in length, have reduced memory requirements, which means more work is done per machine instruction. There is a performance penalty: control unit must determine instruction length, which requires multiple machine cycles. Used in personal computers. |
|
|
What is RISC? |
Reduced Instruction Set Computing. Simpler but less efficient than CISC. Faster processing because no need to calculate instruction length. Used on the ARM chip in cell phones. |
|
|
Pipelines |
Separate (multiple) internal buses that operate simultaneously. This allows tasks and instructions to be broken down into smaller and more numerous parts, which permits the CPU to act on them more quickly and efficiently. |
|
|
What is a Processor Socket? |
It determines which processor a mobo can support provides mechanical and electrical connections between a microprocessor and circuit board locks CPU into place, preventing it from moving or being damaged. They are specific for Intel or AMD |
|
|
What is a Pin grid array (PGA) socket? |
A processor socket that's pins align in uniform rows around the socket but these pins easily bend. |
|
|
What is a staggered pin grid array? |
A staggered pin grid array (SPGA) is a processor socket that has pins staggered over the socket and squeezes more pins into a small space. |
|
|
What is a land grid array? |
Intel tech, uses lands rather than pins. |
|
|
Who are the two major manufacturers of processors? |
Intel and AMD |
|
|
What is the name of the memory cache that is on the same die as the processor? |
L1 cache |
|
|
What is the name of the memory cache that is closest to the processor for but it's not houses on the die? |
L2 cache |
|
|
Which is faster, SRAM or DRAM? |
SRAM, because it does not need to be refreshed. |
|
|
After the system is up and running, what do you enter to check the CPU and Mobo temperatures? |
CMOS |
|
|
What is the the difference between a PGA and a SPGA? |
A pin grid array has pins aligned in uniform rows around the socket. A staggered pin grid array has pins staggered over the socket to squeeze more pins into a small space. |
|
|
How do zero insertion force (ZIF) sockets make it easier to remove and replace the processor? |
ZIF sockets have a small lever on the side that lifts the processor up and out of the socket. Push the lever down and the processor moves into its pins or land connector with equal force over the entire housing. |
|
|
What is the purpose of thermal paste? |
To eliminate air pockets between the heat sink and the processor, helping to draw heat off the processor. |
|
|
What is SRAM? |
Static random access memory. It is inside of the processor's internal memory cache. It is much faster than DRAM. It retains its data bits as long as power is being supplied. |
|
|
What does a multi core processor do? |
It divvies up machine instructions between multiple cores to allow things to be processed faster. Usually divided by odd and even cycles. |
|
|
What is latency? |
How many cycles RAM takes to read and write |
