CPUs
A+ Study tool, covers CPU
| Question | Answer |
|---|---|
| CPU | *central processing unit *very powerful *uses binary *executes instructions |
| Binary | makes codes with 1 and 0 |
| Code book | *machine language that makes the CPU work *programmers use machine language *programmed into every CPU |
| Registers | small amounts of high speed memory contained within a cpu |
| Intel 8088 Processor | oldest CPU used on the first PC |
| CPU clock | *CPU clock tells the CPU to do things *basic unit of time used by CPU *resets computer to clear room for new command |
| External data bus | connects computer to peripheral device |
| CPU pipline | technique for breaking down a sequence into sub operations and executing each simultaneously. |
| ISAs | *instruction set architectures *for CPU: x86 and x64 *abstract model of a computer that defines how the CPU is controlled by the software. |
| CISC | X86 processors 4 GB of RAM developed by intel *more versatile *complex instruction set computer *large complex set of built in instructions -several of which are multiple cycle operations -versatile working with hardware |
| RISC | X64 processors supports 16 exabytes of RAM developed by AMD *commonly used in supercomputers *focused on speed and efficiency *reduced instruction set computing *smaller built in instructions set -focused on efficiency and speed |
| ARM | Advanced Risk Machine * based on RISC architecture *used in mobile, IOT, etc *designed for efficiency Operations and low power consuption |
| CPU Core | a single processing unit within CPU that can execute instructions |
| Clock Speed | number of times a second a circuit can operate |
| Clock Cycle | CPUs speed represented as the number of cycles per second *measured as hertz |
| Differences of 32-bit and 64-bit | amount of data processed in RAM *64-bit is primarily used nowadays |
| Address bus | pathway from CPU to RAM |
| Motherboards | intel uses LAN grid array and AMD use pin grid socket |
| TDP | Thermal Design Power max amount of heat a computer can dissipate under normal operating conditions |
| CPU name components | Intel and AMD: * series name and CPU tier *initial name-identify line of processor (core, ryzen) *Number after series is the performance tier *generation tier |
| CPU cooling | ensures your CPU doesn't overheat *CPU cooling Fan |
| CPU overheating causes | *Dust *CPU and GPU running to much stuff |
| Heat Sink | absorbs heat away from CPU through thermal paste Heat pipes that absorb heat |
| Thermal Paste/pads | improves heat transfer |
| Liquid cooling | uses liquid coolant to absorb heat from CPU *custom loops, phase change cooler, and chillers |
| Resevoir | helps remove air bubbles from coolant, stores liquid coolant. Stores excess coolant |
| custom loops | allows you to select each component to meet the needs of your system |
| AIO cooler | All in one system |
| Phase Change cooler | uses a cooling method similar to modern refrigerator. chills coolant as it goes through |
| Chiller system | chills coolant before pumped into system |
| LAN grid Array | used on intel CPU CPU pins are on motherboard rather than cpu |
| Pin Grid Array | AMD CPU Pins are on CPU |
| ZIF | Zero insertion Force Makes it easy to insert CPU without much pressure |
