Network interface Card (NIC):-
first definition:
-> NIC provides connection between the computer and network communication media.
-> To move data from the pc's system to the network medium.
-> Able the networking devices works properly.
second definition:
-> A network interface card (NIC) is a hardware component, typically a circuit board or chip, which is installed on a computer so that it can connect to a network. Modern NICs provide functionality to computers such as support for I/O interrupt, direct memory access (DMA) interfaces, data transmission.
Purpose of NIC -
1. NIC allows both wired and wireless communications.
2. NIC allows communications between computers connected via local area network (LAN) as well as communications over large-scale network through Internet Protocol (IP).
3. NIC is both a physical layer and a data link layer device.
NIC Card function -
NIC cards are effectively the middle man between your computer and the network. They are responsible for translating data on the computer into a form that can be transferred via a network cable or wireless network signal.
NIC cards also control the data as it is sent to other devices on the network. NIC cards therefore have a big influence on how quickly network data is sent and received, so if your computer's internet speed is slow, it's possible that the NIC card may be to blame. This is particularly the case if your NIC card is an older model as older NIC cards may not be able to adequately support top network speeds today.
Types of NIC Card -
1. Internal Network Cards
In internal networks cards, motherboard has a slot for the network card where it can be inserted. It requires network cables to provide network access.
Internal network cards are of two types.The first type uses Peripheral Component Interconnect (PCI) connection, while the second type uses Industry Standard Architecture (ISA).
2. External Network Cards
In desktops and laptops that do not have an internal NIC, external NICs are used. External network cards are of two types: Wireless and USB based.
Wireless network card needs to be inserted into the motherboard, however no network cable is required to connect to the network.
They are useful while traveling or accessing a wireless signal.
