What is an I/O Controller (IOC)?

What does IOC stand for?

I/O Controllers are a series of Microchips which help in the communication of inFormation between the Central Processing Unit and the Motherboard. The primary motive of this Device is to assist within the interplay of Peripheral Devices with the manage devices (CUs). Put surely, the I/O conTroller allows inside the connection and control of numerous Peripheral devices, which might be enter and Output gadgets. It is usually hooked up at the motherboard of a Computer. However, it may also be used as an Accessory in the case of replacements or which will add extra peripheral devices to the pc.

I/O controllers are also called channel I/O, DMA controllers, peripheral Processors or I/O processors.

What Does I/O Controller Mean?

As CPU speeds expanded, so did the need for faster statistics transmissions among the peripheral gadgets and the manipulate uNit. The Input/Output controllers paintings by way of receiving Commands from the CPU, then sending the commands to the gadgets for which they may be intended. The I/O controller additionally manages statistics communications from the peripheral gadgets. Thus, I/O controllers save the processing power of the CPU, which could otherwise be wasted at the same time as transmitting facts. Faster I/O controllers lead to quicker CPU communications, which in flip leads to faster processing speed.

The I/O controllers are generally preinstalled at the motherboard of the Laptop. However, those gadgets can only accommodate sure commonplace gadgets. Some specific gadgets may also have a separate I/O controller. Such devices have to be connected to the pc using Expansion Slots.
