PCI - these are slots in the motherboard for connecting external.

Cards like nic's, other graphic cards etc.

NIC (network interface card) - these are cards used to connect your.

Computer to a network. These nic card consist of MAC address.

And this address connect our computer to the network. MAC Address (media access control address) its a 48 bit hexa decimal address on which 24 bit is assigned by OUI (organisation unique identifier) and the other 24 bit is assigned by the manufacturer. NOTE that each computer have its own mac address it never changes.

Of these IRQ values. Each process have one irq number like.

IRQ1, IRQ2 etc. For example: if the processor is working on.

Some process and the bus introduces a function with IRQ.

Number IRQ5 the processor will stop the present function and it process that function after that it will automatically resume to the previous function.

PCI - Peripheral Component Interconnect

NIC- Network Interface Card

IRQ- Interrupt Request

NICS-Network Interface Card Slot

What is mean by PCI, NIC & IRQ? explain about that please.

Short, how? and in which form factors?

What is mean by PCI, NIC & IRQ? explain about that please.

What is motherboard BIOS?

BIOS - Basic Input Output System.

1. BIOS does the booting process.

2. BIOS checks the input and output devices are operational or not when our computer get starts.

I need information about southern bridge and north bridge.
