 CPU | The CPU sockets today are ZIF sockets. Thermal compound helps to conduct heat away from the CPU. When you are installing a used CPU, clean the CPU and the base of the heat sink with isopropyl alcohol. Doing this removes all traces of old thermal compound. Do not touch the CPU contacts at any time. |
| Heat Sink/Fan Assembly | It is a two-part cooling device. The heat sink draws heat away from the CPU. The fan moves the heat away from the heat sink. The heat sink/fan assembly usually has a 3-pin power connector. |
| RAM | RAM provides temporary data storage for the CPU while the computer is operating. RAM is volatile memory, which means that its contents are lost when the computer is shut down. Typically, more RAM will enhance the performance of your computer |
| A hard disk drive (HDD) | It is an internal drive. It aligns with the 3.5-inch drive bay. |
| Optical drives and Floppy drives | are installed in drive bays that are accessed from the front of the case. Optical drives and floppy drives store data on removable media. Drives in external bays allow access to the media without opening the case. |
| Optical Drive | Is a storage device that reads and writes information to CDs and DVDs. A Molex power connector provides the optical drive with power from the power supply. A PATA cable connects the optical drive to the motherboard. It aligns with the 5.25-inch drive bay. |
| Floppy Disk Drive (FDD) | Is a storage device that reads and writes information to a floppy disk. A Berg(4-pin)power connector provides the FDD with power from the power supply. A floppy data cable connects the FDD to the motherboard. It aligns with the 3.5-inch drive bay. |
| Adapter cards | Are installed to add functionality to a computer. Adapter cards must be compatible with the expansion slot. |
| PCIe x1 NIC | Enables a computer to connect to a network. NICs use PCI and PCIe expansion slots on the motherboard. |
| PCI wireless NIC | Enables a computer to connect to a wireless network. Wireless NICs use PCI and PCIe expansion slots on the motherboard. Some wireless NICs are installed externally with a USB connector. |
| PCIe x16 video adapter card | Is the interface between a computer and a display monitor. An upgraded video adapter card can provide better graphic capabilities for games and graphic programs. Video adapter cards use PCI, AGP, and PCIe expansion slots on the motherboard. |
| Internal Cables | Power cables are used to distribute electricity from the power supply to the motherboard and other components. Data cables transmit data between the motherboard and storage devices, such as hard drives. |
| Motherboard Power Connections | The Advanced Technology Extended (ATX) main power connector will have either 20 or 24 pins. |
| SATA Power Connectors | Use a 15-pin connector. SATA power connectors are used to connect to hard disk drives, optical drives, or any devices that have a SATA power socket. |
| PATA Data Cables | Is sometimes called a ribbon cable because it is wide and flat. The PATA cable can have either 40 or 80 conductors. A PATA cable usually has three 40-pin connectors. One connector at the end of the cable connects to the motherboard. The other two connectors connect to drives. If multiple hard drives are installed, the master drive connects to the end connector. The slave drive connects to the middle connector. |
| SATA Data Cables | Has a 7-pin connector. One end of the cable is connected to the motherboard. The other end is connected to any drive that has a SATA data connector. |
| Floppy Data Cables | has a 34-pin connector. The floppy drive data cable has a stripe to denote the location of pin 1. A floppy drive cable usually has three 34-pin connectors. One connector at the end of the cable connects to the motherboard. The other two connectors connect to drives. |
| Power-on self test (POST) | When the computer is booted, the basic input/output system (BIOS) performs a check on all of the internal components. Checks to see that all of the hardware in the computer is operating correctly. |
| Complementary Metal Oxide Semiconductor (CMOS) | Is maintained by the battery in the computer. If this battery dies, all BIOS setup configuration data will be lost. If this occurs, replace the battery and reconfigure the BIOS settings. |
