Systems architecture examines the internal structure and operation of the Central Processing Unit (CPU). Students must understand how hardware components fetch, decode, and execute instructions within computer memory.

The Von Neumann architecture forms the basis of modern computer systems.
Find key definitions and how they work:
- Program Counter (PC),
- Memory Address Register (MAR),
- Memory Data Register (MDR), and
- Accumulator (ACC)

Also the idea of
- Arithmetic Logic Unit (ALU) and
- Control Unit (CU).

CPU performance depends directly on clock speed measured in Hertz, cache size providing high-speed memory access, and the number of processor cores enabling parallel processing of instruction streams.
Find what they are and how they work:
- Clock Speed
- Core
- Cache Size
- Additional Hardware
