SATA is an interface used to connect mass storage devices such as hard drives and Blu-ray drives. SATA 3 has a native transfer rate of 6 Gbit/s, which is twice as fast as SATA 2, the previous revision. This is particularly useful if you use an SSD as it can perform at higher speeds.
Fan headers are connection points on the motherboard that cooling fans can be connected to. Fans can also be connected straight to the power supply, but when connected to the motherboard you gain much finer control over them through software.
The motherboard has USB 3.0 headers, which are pin connections that you can connect additional USB ports to.
M.2 is an interface used to connect different types of devices, mainly mass storage devices like M.2 SSDs. It is a revision of mSATA and can support much higher data transfer rates.
Trusted Platform Module (TPM) is a component that significantly increases security. One example is that it allows encryption keys to be created in a secure environment, minimizing the risk of a hacker gaining access.
U.2 is an interface used to connect different types of devices, mainly mass storage devices. It has the same performance as M.2, but U.2 SSDs come in the form of regular 2.5" SATA drives and could therefore support much higher capacities than mSATA drives.
Expansion slots
PCIe slots allow you to connect various components to the motherboard, such as graphics cards and SSDs. The number of data-transmission lanes (specified by the number after the 'x') determines the data transfer rate. PCIe 4.0 provides a 16 GT/s bit rate that doubles the bandwidth provided by PCIe 3.0.

PCIe slots allow you to connect various components to the motherboard, such as graphics cards and sound cards. The number after the 'x' represents the number of lanes, with more lanes supporting higher data transfer rates. PCI Express 3.0 has a bit rate of 8 GT/s, delivering 985 MB/s per lane.
Using PCIe slots, you can connect different components to your motherboard, such as graphics cards and RAID cards. The number after the 'x' represents the number of data-transmission lanes. More lanes result in faster data transfer rates. A PCIe x1 slot has one lane and can move data at one bit per cycle.
PCI slots allow you to connect peripherals to the motherboard, most commonly graphics cards but also others such as sound cards and network cards. PCI has been superseded by PCI Express which offers faster data transfer rates, but many cards today still use PCI.
PCIe slots allow you to connect graphics cards, SSDs, and other components to the motherboard. The number after the 'x' represents the number of lanes, with more lanes supporting higher data transfer rates. PCI Express 2.0 has a transfer rate of 5 GT/s, providing 500 MB/s per lane.
PCIe slots enable you to connect various components to your motherboard, for example, graphics cards, RAID cards, SSDs. The number of data-transmission lanes (specified by the number following 'x') determines the data transfer rate. A PCIe x4 slot has 4 lanes, with a speed of 4 bits per cycle.
PCIe slots allow you to connect components such as graphics cards and sound cards to the motherboard. The number after the 'x' represents the number of data-transmission lanes. More lanes result in faster data transfer rates. A PCIe x8 slot has 8 lanes and can move data at 8 bit per cycle.
Audio
When a digital signal is converted to an analog one (for example when playing audio through speakers or headphones), a certain amount of noise is carried in the signal. A higher SNR means that there is less noise and the audio quality is better.
Each channel is a separate stream of audio information. More channels can provide a more realistic experience, such as providing surround sound.
S/PDIF is an interface used to transmit digital audio with high fidelity.
More connectors means that more audio devices such as speakers or microphones can be connected.
Storage
RAID is a storage technology that combines multiple disks into one unit. RAID 1 mirrors the data across the drives. This gives you greater data security as if one drive fails, the data will still be accessible from another.
RAID is a storage technology that combines multiple disks into one unit. RAID 10 (1+0) stripes and mirrors the data across the drives. It gives increased capacity and performance compared to a single disk. It also provides greater data security as if one drive fails, the data will still be accessible from another.
RAID is a storage technology that combines multiple disks into one unit. RAID 5 stripes the data across the drives, giving increased performance compared to a single disk. It also provides greater data security as if one drive fails, the data will still be accessible from another due to the use of parity.
RAID is a storage technology that combines multiple disks into one unit. RAID 0 stripes the data across the drives, giving increased performance and capacity compared to a single drive. The drawback is that if one drive fails, you lose the data on all drives.
RAID is a storage technology that combines multiple disks into one unit. RAID 0+1 stripes and mirrors the data across the drives. This gives increased capacity and performance compared to a single disk. It also provides greater data security in case one drive fails, as the data will still be accessible from another.
Miscellaneous
Thunderbolt is a connection that allows you to attach external peripherals to a computer, and can carry both data and display signals. Using a single port you can connect up to six devices through a hub or daisy chain configuration.
