Document Summary

Bus multiwiring, data ows through this highway to various components: can have several bus: data, storage etc. A cooling fan on top of cpu. Random access memory: uses gates, takes same amount of time to get the info no matter where it is. Dynamic ram: gets refreshed a lot. It cannot think by itself needs to be programmed. Monday, february 13, 2017: arithmetic (math, logic (boolean algebra, and, or gates, true or false) To make processor faster use gold, its a very good conductor. Processing speed: there is a internal clock that ticks every nanosecond, every tick there is an operation, tick means that the a cycle has passed. Components of the cpu: arithmetic logic unit (alu) Where arithmetic and logic, comparison computation: cpu has memory units at different levels, memory hierarchy (fasts to slower, by several magnitudes also cheaper) Then secondary storage (but are slower, can store more: control unit.
