A mining rig is a computing device for mining cryptocurrency, most often built on the basis of a computer with several graphics cards. The chance of receiving a block reward depends on its power.

FPGA is a field-programmable gate array, a semiconductor chip that can be configured for specific tasks after it has been manufactured. In mining, it occupies an intermediate position between graphics cards and ASICs.

A riser is an extension adapter that connects a graphics card to the motherboard and allows several cards to be conveniently placed in a mining rig.

A graphics processing unit (GPU) is the computing chip of a graphics card, capable of simultaneously processing many parallel tasks. Thanks to this property, GPUs long remained the main hardware for cryptocurrency mining.

An ASIC is an integrated circuit designed to perform a single task. In mining, such chips are used for the most efficient computation of a specific cryptocurrency algorithm.
