What is a Processor?
-inputs outputs-software instructions to useful information-central processing unit (CPU)

Transistor-N and P (NPN shown)-voltage input at gate-flow=1, no flow=0-combine transistors

Integrated Circuit-enhance power of transitor-mass production-before circuit, wires-store and process bits and bytes

CPU-condenses chips and circuits into microprocessor-controls the whole computer-chips onto wafer

CPU-components-control unit: coordinator-arithmetic/logic unit (ALU): logic-registers: bytes in process

CPU-components-cache: temp storage area, boosts speed-clock speed: internal clock in GHz-overclocking
![Page 9: Hardware](https://reader033.fdocuments.in/reader033/viewer/2022060109/5556489cd8b42a8d0f8b4cb3/html5/thumbnails/9.jpg)
RAM-random access memory-works with CPU-not enough-slow-temporary storage area to work with apps

ROM-read-only memory-permanent storage-fixed circuit states
![Page 11: Hardware](https://reader033.fdocuments.in/reader033/viewer/2022060109/5556489cd8b42a8d0f8b4cb3/html5/thumbnails/11.jpg)
Video Memory-graphics support-buffer between microprocessor and display-may have graphics processing unit (GPU) to assist CPU
![Page 12: Hardware](https://reader033.fdocuments.in/reader033/viewer/2022060109/5556489cd8b42a8d0f8b4cb3/html5/thumbnails/12.jpg)
Motherboard-connects all the components-slots for microprocessor, RAM, ROM, video card, extensions-form controls size of computer
![Page 13: Hardware](https://reader033.fdocuments.in/reader033/viewer/2022060109/5556489cd8b42a8d0f8b4cb3/html5/thumbnails/13.jpg)
Bus-connects components of motherboard-speed impacts CPU performance-front side bus (FSB) feeds instructions to CPU

Machine Cycle-organizes processing instructions-4 steps:
-record location-fletching from RAM-decode-send to ALU

Multiprocessing-multiple processors-parallel processing: divide work-graphic rendering-save time
![Page 16: Hardware](https://reader033.fdocuments.in/reader033/viewer/2022060109/5556489cd8b42a8d0f8b4cb3/html5/thumbnails/16.jpg)
Multicore-multiple CPUs on one chip-increased speed-slower clock speed
