Bluetooth is a type of wireless connection that syncs two compatible devices together, such as a tablet and a set of Bluetooth speakers.
DisplayPort is a port that allows you to connect laptops, tablets and desktop PCs to a monitor or TV. It is much smaller than HDMI, so is used on ultra-thin laptops, tablets and gaming PCs that support multiple monitors. DisplayPort supports Full HD and 4K video, along with high-definition audio.
DVI stands for Digital Visual Interface. It is a common way to connect desktop PCs and monitors. It transmits Full HD video without audio.
Ethernet is a port that allows you to connect you PC to the internet via a cable. There are two speeds of ports: 10/100 Ethernet and 10/100/1000 Gigabit Ethernet.

A graphics card is a processor dedicated solely to handling the visuals your PC produces.
HDMI stands for High-Definition Multimedia Interface. It is a port that allows you to connect your device to a TV or monitor. It is capable of transmitting Full HD video and audio.
The motherboard, or main board, is a major component in your PC. All the other components connect to it, including the processor, RAM, storage and graphics.
PCIe stands for Peripheral Component Interconnect Express. PCIe ports are found inside desktop PCs and are used for adding graphics cards, sound cards and other internal components.
A power supply can be either external (in laptops and tablets) or internal (desktop PCs). Desktop PCs power supplies are rated in watts.
A core is the part of the processor that processes information.
USB stands for Universal Serial Bus. It is a universal port for connecting peripherals to your PC or tablet.
VGA stands for Video Graphics Array. It is an older way laptops and desktops connect to monitors and TVs. It is being replaced by HDMI, DisplayPort and DVI. It cannot transmit HD video or audio.
