Processor
Processor socket
Mechanical component(s) that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the processor to be replaced without soldering.
Socket AM4
Compatible processor series
A processor which is compatible with this device, belongs to a 'series' which is part of 'family' e.g Celeron D, Celeron G, Celeron M, or, in some cases, is the same as 'family'.

Memory slots type
A memory slot, also known as a memory socket or RAM slot, is what allows computer memory (RAM) to be inserted into the computer. Depending on the motherboard, there will usually be 2 to 4 memory slots (sometimes more on high-end motherboards). The most common types of RAM are SDRAM and DDR for desktop computers and SODIMM for laptop computers, each having various types and speeds.
DIMM
Memory channels
Dual-channel
ECC
ECC means Error Correction Code, and it is memory that is able to detect and correct some memory errors without user intervention.

Non-ECC

Supported memory clock speeds
Memory clock speed is the time it takes for a computer to complete basic operations. It refers to the computer's processing speed and is measured in hertz. It is however not such a reliable measure of a computer's speed as it doesn't take into account other factors like RAM and cache size.

RAID levels
RAID is a storage technology that combines multiple disk drive components into a logical unit for the purposes of data redundancy and performance improvement. Data is distributed across the drives in one of several ways, referred to as RAID levels, depending on the specific level of redundancy and performance required.

Internal I/O
USB 2.0 connectors
The end of a cable with a USB 2.0 connector. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), in addition to the "USB 1.x Full Speed" signaling rate of 12 Mbit/s. USB 2.0 connectors are usually colored black.

USB 3.2 Gen 1 (3.1 Gen 1) connectors
This is a connector (normally attached to a cable) for USB 3.0. USB 3.0 is the second major revision of the Universal Serial Bus (USB) standard for computer connectivity. First introduced in 2008, USB 3.0 adds a new transfer mode called "SuperSpeed," (distinguishable from USB 2.0 by either the blue colour of the port or the initials SS) capable of transferring data at up to 5Gbit/s—more than ten times as fast as the 480 Mbit/s top speed of USB 2.0.

BIOS
BIOS type
The BIOS (Basic Input/Output System) initializes and tests system hardware components, and loads a bootloader or an operating system from a mass memory device. The BIOS additionally provides abstraction layer for the hardware, i.e. a consistent way for application programs and operating systems to interact with the keyboard, display, and other input/output devices. There are several types of BIOS, including the motherboard ROM BIOS, video BIOS, drive controller BIOS, network adapter BIOS, and SCSI adapter BIOS.
