A game controller, gaming controller, or simply controller, is an input device used with video games or entertainment systems to provide input to a video game, typically to control an object or character in the game. Before the seventh generation of video game consoles, plugging in a controller into one of a console's controller ports was the primary means of using a game controller, although since then they have been replaced by wireless controllers, which do not require controller ports on the console but are battery-powered.
disk controller         
CONTROLLER FOR DISK STORAGE, USUALLY INTEGRATED INTO THE DRIVE
Hard disk controller; Hard drive controller; HD controller; Drive controller
<hardware, storage> (Or "hard disk controller", HDC) The circuit which allows the CPU to communicate with a {hard disk}, floppy disk or other kind of disk drive. The most common disk controllers in use are IDE and SCSI controllers. Most home personal computers use IDE controllers. High end PCs, workstations and network {file servers} mostly have SCSI adaptors. (1998-03-16)

CONTROLLER FOR DISK STORAGE, USUALLY INTEGRATED INTO THE DRIVE
Hard disk controller; Hard drive controller; HD controller; Drive controller
The disk controller is the controller circuit which enables the CPU to communicate with a hard disk, floppy disk or other kind of disk drive. It also provides an interface between the disk drive and the bus connecting it to the rest of the system.

Graphics card

A graphics card (also called a video card, display card, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a monitor. Graphics cards are sometimes called discrete or dedicated graphics cards to emphasize their distinction to integrated graphics processor on the motherboard or the CPU. A graphics processing unit (GPU) that performs the necessary computations is the main component in a graphics card, but the acronym "GPU" is sometimes also used to refer to the graphics card as a whole.

Most graphics cards are not limited to simple display output. The graphics processing unit can be used for additional processing, which reduces the load from the central processing unit. Additionally, computing platforms such as OpenCL and CUDA allow using graphics cards for general-purpose computing. Applications of general-purpose computing on graphics cards include AI training, cryptocurrency mining, and molecular simulation.

Usually, a graphics card comes in the form of a printed circuit board (expansion board) which are to be inserted into an expansion slot. Others may have dedicated enclosures, and they are connected to the computer via a docking station or a cable. These are known as external GPUs (eGPUs).

Graphics cards are often preferred over integrated graphics for increased performance.
