Two most important motivations for learning how computers work.

• Computer organization and Computer architecture

• Computer optimization and optimization tuning

• Program optimization and system tuning

• System tuning and computer system

We must become familiar with how various circuits and components fit together to create working computer systems. We do this through the study of ___________.

• Computer architecture

• Computer organization

• Computer systems

• Computer administration

_______________includes many elements, such as instruction sets and formats, operation codes, data types, the number and types of registers, addressing modes, main memory access methods, and various I/O mechanisms.

• Computer optimization

• Computer organization
