| A | B |
|---|
| system bus speeds | 1600, 1333, 1066 or 800 MHz |
| processor core frequency | usually measured in gigahertz such as 3.2GHz |
| LGA socket | Intel socket for their processors - Land Grid Array |
| multiprocessing | abilty for the processor to do more than one thing at a time |
| L1 cache | memory on the processor die |
| DDR3 | type of memory for the Core series of processors |
| HT | hyper-threading - allows the processor to have two threads |
| I/O unit | arithmetic logic unit manages the data and instructions entering and leaving the processor. |
| ALU | manages does all the logical comparisons and calculations |
| registers | small holding areas on the processor chip that works like ram |
| multiplier | multiply the system bus frequency by the this, you get the processor frequency. |
| overclocking | running your processor faster than the manufacturer stated speed |
| multi-core processing | multiple CPUs in one die |
| quad core | four CPUs on one computer die |
| memory cache | holds data and instructions that the memory controller anticipates is needed |
| microcode | the instruction sets and and the groups of instructions sets for the CPU |
| execute disable bit | an Intel security feature that prevents software from executing or reproducing itelf if it appears to be malicious. |
| cooler | sits on top of the processor to cool it. |
| heat sink | has fins that draw heat away from the CPU |
| thermal compound | placed between the heat sink and the processor to aid in heat transfer |
| liquid cooling | uses a pump with a liquid coolant to cool the CPU |
| peltier cooling | applies an electrical current to the metal - makes cool on one side |
| dust | a source of ESD and heat retention |
| 32 or 64 bit | the data path of the processor. |
| AM2 or AM3 | socket for the AMDs Phenom processors |
| ACPI | advanced configuration and power interface |
| s1 | hard drive and monitor are turned off |
