| Processors | these processor can run on system boards that run at 100 MHz or higher |
| Sockets | earlier sockets used a low insertion force (LIF) method |
| SIMMs | must be inserted in pairs in memory banks. Single DIMMs can be used on a system board, and RIMMs or a C-RIMM must fill every RIMM slot on a system board. |
| Newer System Boards | don't have Level 2 cache memory because L2 cache is now included inside the processor housing |
| Low voltage | differential (LVD) signaling used by ultra2 SCSI and allows for faster data transfers and longer cable lengths up to 25 meters |
| Data Width | of each of the common bus on a system board is what you should know |
| PCI bus | is the fastest bus on the system board that can support peripherals devices |
| USB ports | connect to the USB bus that can support up to 127 devices daisy chained together. |
