7. Data management and storage
What are different types of capacity? - Bit, byte, KB, MB, GB
What are different types of clock speed? - MHz, GHz
What are different types of chip density? - 45, 32, 22, 14 nm technology
,What are different types of word lengths? - 32 bit, 64 bit
Define: Processor (a.k.a. CPU) - Where symbols, characters, and numbers are manipulated
Brain of the computer
Integrates arithmetic, logic, and control circuits on a single chip
Typically have multiple cores (2 or 4 is common)
