List and describe the components found in a pentium processor.

An input/output (I/O) unit manages data and instructions entering and leaving the processor. A control unit manages all activities inside the processor itself. One or more arithmetic logic units (ALUs) do all logical comparisons and calculations inside the processor. Registers, which are small holding areas on the processor chip, work much like RAM does outside the processor to hold counters, data, instructions, and addresses that the ALU is currently processing. Internal memory caches (L1, L2, and possibly L3) hold data and instructions waiting to be processed by the ALU. Buses inside the processor connect components within the processor housing.
