Network interface cards (NICs) allow computers to connect to networks by serving as the interface between the computer and network. NICs have components like an Ethernet controller, MAC address, transceiver, PHY chip, buffer/RAM, bus interface, and driver software. They enable connectivity, data transmission, performance benefits, and security while connected to a network but may face compatibility issues, limited bandwidth, security concerns, and increased power consumption in some cases.

3. (FUNCTION OF NETWORK INTERFACE CARDS) A
NETWORK INTERFACE CARD (NIC) IS A
HARDWARE COMPONENT THAT ALLOWS A
COMPUTER TO CONNECT TO A NETWORK AND
COMMUNICATE WITH OTHER DEVICES. IT SERVES
AS THE INTERFACE BETWEEN THE COMPUTER
AND THE NETWORK, ENABLING DATA
TRANSMISSION IN BOTH DIRECTIONS. NICS
SUPPORT VARIOUS NETWORKING
TECHNOLOGIES, SUCH AS ETHERNET OR WI-FI

4. CONFIGURATION OF NETWORK
INTERFACE CARD. HERE ARE
GENERAL STEPS FOR (NIC)
CONFIGURATION:

5. 1.ACCESS NETWORK SETTINGS:ON
WINDOWS: GO TO CONTROL PANEL >
NETWORK AND SHARING CENTER >

6. 2.SELECT THE NIC:IDENTIFY THE NIC
YOU WANT TO CONFIGURE

7. 3. CONFIGURE IP ADDRESS:CHOOSE
BETWEEN STATIC (MANUAL) OR
DYNAMIC (DHCP) IP ADDRESSING.

8. 4. ADVANCED SETTINGS:ACCESS
ADVANCED SETTINGS TO CONFIGURE
SPECIFIC PARAMETERS LIKE SPEED AND
DUPLEX SETTINGS FOR ETHERNET NICS.

9. 5.SAVE CHANGES:APPLY THE CHANGES
AND SAVE THE CONFIGURATION.

10. 6. TEST CONNECTIVITY:VERIFY
CONNECTIVITY BY TRYING TO ACCESS
RESOURCES ON THE NETWORK OR
PINGING OTHER DEVICES.

11. COMPONENTS OF
NETWORK INTERFACE
CARDS. HERE ARE
COMPONENTS OF (NIC)

12. 1. ETHERNET CONTROLLER
RESPONSIBLE FOR HANDLING THE
ETHERNET PROTOCOL, WHICH GEVENS
HOW DATA IS TRANSMITTED OVER A
WIRED NETWORK

13. 2. MAC ADDRESS
KNESEN AS THE MEDIA ACCESS
CONTROL (MAC) ADORESS. IT ENSURES
EACH NIC ON A NETWORK HAN A
DISTINCT ADDRESS FOR PROPER
COMMUNICATION

14. 3. THUNSCEIVER CONVERT ELECTRICAL
SIGNALS FROM THE COMPUTER INTO
SIGNALS SUITABILE FOR TRANSMISSION
OVER THE NETWORK MEDIUM

15. 4. PHY (PHYSICAL LAYER) CHIP
TRANSLATING DATA BETWEEN THE DATE
LINK LAYER AND THE PHYSICAL
MEDIUM. IT INCKIDES COMPONENTS
SHE LINE DRIVERS AND RECEIVERA FOR
SIGNAL MODULATION

16. 5. BUFFER/RAM
STORAGE SPACE USED FOR STORING
INCOMING AND OUTGOING DATA
PACKETS. THE BUFFER HELPS MANAGE
DATA FLOW, PREVENTING DATA LORS
DUNNG PERTADS OF HIGH NETWORK
TRAFFIC

17. 6. BUS INTERFACE
IT FACILITATES COMMUNICATION
BETWEEN THE RAC AND THE
COMPUTER'S CENTRAL PROCESSING
UNIT (CPU)

18. 7. DRIVER SOFTWAREIT ALLOWS THE
OG TO CONTROL AND COMMUNICATE
WITH THE NIC. ENSURING PROPER
INTEGRATION AND FUNCTIONALITY

19. 8.LED INDICATORS LIGHT EMITTING
DIODES THAT PROVIDE VISUAL
INDICATIONS OF THE NC STATUS, SUCH
AS POWER CONNECTIVITY, AND DATA
TRANSFER ACTIVITY.

ADVANTAGES IN
COMPUTER
NETWORKING:

21. ▪ 1. Connectivity: NICs
enable computers to
connect to a network,
facilitating communication
and data exchange
between devices.
▪ 2. Data Transmission: They
ensure efficient and
reliable communication
between devices by
managing the flow of data.
▪ 3. Performance:They
support various data
transfer rates, allowing
for faster communication
between computers and
improving overall
network efficiency.
▪ 4. Security:This helps in
securing data during
transmission and
protecting against
unauthorized access.

22. ▪5.Scalability:NICs can support scalability by
accommodating increased network traffic
or additional devices.

23. NETWORK INTERFACE
CARDS (NICS)
DISADVANTAGES:

24. ▪ 1. Compatibility
Issues:may face
compatibility issues with
certain operating systems
or network architecture
▪ 2.Limited Bandwidth:
Some NICs may have
limitations on data transfer
rates, impacting the
overall network speed and
performance, especially in
high-demand scenarios.
▪ 3. Security Concerns:NICs
can be vulnerable to security
threats. Exploits targeting
NIC firmware or drivers may
compromise the integrity
and confidentiality of
network data.
▪ 4.Power Consumption:Some
NICs may consume a
significant amount of power,
especially in scenarios
where devices need to
operate on limited power
sources like batteries.
