It is a printed circuit board that you can insert into a computer to give it added capabilities
The "primary circuit board" for a computer is called the "Motherboard". This is the board that contains the housing and sockets for all of the coprocessors, resistors, and circuit pathways that make your computer operate. This board also contains expansion slots, in which you insert expansion cards, extending the capabilities of the system.
These can be called several things such as peripheral cards, expansion cards, and occasionally daughterboards.
NO my dear
An expansion card, not cord is a printed circuit board that is inserted into an electrical connector. It is used to move information between the internal hardware of a computer system.
expansion slots :D
It's usually a circuit board made to be easily added to your computer (via an expansion slot). They most commonly contain additional RAM memory, but there are many other choices (math chips, communication chips, graphic chips, etc.).
Motherboard in which all the peripheral are connected such as processor,memory and expansion slot
In most designs, the CPU is located on motherboard, not on an expansion card.
A motherboard (also called mainboard, main circuit board, or mobo) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. ... Motherboard means specifically a PCB with expansion capabilities.
A motherboard or a system board is a main component that ties in everything together. It connects the CPU, expansion cards, memory, storage, and external peripherals.

expansion slots are found on the motherboard
