NIC stands for Network Interface Card,Advantages and
DisAdvantages of NIC are as follows:
If NIC Card is present then data flow is possible and if
NIC card is not available Data flow is Not possible between
Networks NIC Card is provided with Port RJ45 Port and this
is the port through which Data transfer is Possible is
possible in between Networks.The Disadvantage of NIC is
Data is not secured in NIC Connection as Data can be Hacked.
The Advantages and Disadvantages of NIC card is
1)NIC Card helps for communication between 2 systems
2)NIC Card helps to connect to Remote Systems.(Advantage)
3)NIC Card data can be transffered from one system to
4)NIC Card data is not secure.
All wired communication should go through via NIC only to
the other computeres or network devices ; So there is no
disadvantage on this . And security can be implemented
through external softwares or encryption softwares to
encrypt the data and send to other PCs
A network interface card, network adapter, network
interface controller (NIC), or LAN adapter is a computer
hardware component designed to allow computers to
communicate over a computer network. It is both an OSI
layer 1 (physical layer) and layer 2 (data link layer)
device, as it provides physical access to a networking
medium and provides a low-level addressing system through
the use of MAC addresses. It allows users to connect to
each other either by using cables or wirelessly.
Although other network technologies exist, Ethernet has
achieved near-ubiquity since the mid-1990s. Every Ethernet
network card has a unique 48-bit serial number called a MAC
address, which is stored in ROM carried on the card. Every
computer on an Ethernet network must have a card with a
unique MAC address. Normally it is safe to assume that no
two network cards will share the same address, because card
vendors purchase blocks of addresses from the Institute of
Electrical and Electronics Engineers (IEEE) and assign a
unique address to each card at the time of manufacture.
