Introductory Message
Welcome to learning area and grade level!
The Learning Activity Sheet is a product of the collaborative efforts of the
Schools Division of ANTIQUE and DepEd Regional Office VI - Western Visayas
through the Curriculum and Learning Management Division (CLMD). This is
developed to guide the learning facilitators (teachers, parents and responsible adults)
in helping the learners meet the standards set by the K to 12 Basic Education
Curriculum.
The Learning Activity Sheet is self-directed instructional materials aimed to
guide the learners in accomplishing activities at their own pace and time using the
contextualized resources in the community. This will also assist the learners in
acquiring the lifelong learning skills, knowledge and attitudes for productivity and
employment.
For learning facilitator:
The Computer Systems Servicing Activity Sheet will help you facilitate the
leaching-learning activities specified in each Most Essential Learning Competency
(MELC) with minimal or no face-to-face encounter between you and learner. This will
be made available to the learners with the references/links to ease the independent
learning.
For the learner:
The Computer Systems Servicing Activity Sheet is developed to help you
continue learning even if you are not in school. This learning material provides you
with meaningful and engaging activities for independent learning. Being an active
learner, carefully read and understand the instructions then perform the activities and
answer the assessments. This will be returned to your facilitator on the agreed
schedule.

II. Background Information for Learners
Computers would not be able to function if they do not have functioning hardware
accurately. A computer network that is set-up correctly makes it easy to share data in
an organization. The computer hardware is the compilation of all the physical devices
that help with interactions between the devices in a network.
This Learners activity sheet will help you understand the importance of having network
interface card in your computer. Identify the ways a NIC can connect to the internet,
appreciate how wired and wireless NIC works necessarily to your computers and of
course to learn personally how to configure network interface cards.
Now that you have a glimpse of what to expect on this lesson, are you ready to learn?

IV. Activity Proper
In this LAS, topics will be introduced progressively for easy understanding. After
thoroughly reading all the lessons, carefully answering the assessment exercises,
answering all the guide questions, skillfully performing all the activities, showing
evidences of learning, you will gain a considerable knowledge and skills, essential to be
successful in the field of computer systems servicing.
Reminder! Just follow the instructions given in this LAS. Now let us start exploring new
things by reading the content of this LAS.
NETWORK INTERFACE CARD? FUNCTIONS? CONFIGURATION?
Network Interface Card or Network Interface Controller (NIC) card plays an important
role in the function of your computer as it is the network adapter. So what is NIC?
Network Interface Card (NIC) is a hardware unit, which is inbuilt inside a computer
provided with a slot, it connects the computer to a computer network for communication
with other devices via buses.
A hardware component, where network controllers are integrated on to a circuit board
that uses standard OSI model of 7 layers to communicate and it acts like a transreceiver, where it can transmit and receives at the same time while communicating with
other devices.
Functions of NIC
 It acts like a translator, which converts data into a digital signal
 Communication can be either by using cable wire by the router which is
wireless over the server network
 To communicate over a long distance a network adapter is used.
Types of NIC
1. Ethernet NIC
2. Wireless NIC
Ethernet NIC
- A slot for a cable where we have to plug one end of the ethernet cable into the slots
of the computer and another end of the cable is plugged into the modem, likewise,
various devices are connected to make a communication set up between them.
Classification of Ethernet NIC:
1. 5-Base T: It was developed in 1973, which can transmit, paragraphs using
coaxial cable up to a distance 1000mts.
2. 10-Base T: It was developed in 1987, it uses twisted cables like telephonic
cables for communication.
3. 100-Base T: It is also known as fast ethernet, the speed of data transmitted is
very high.
4. Gigabit Ethernet: It is also named as 1000-Base T ethernet, the special feature
of this is it increases the network bandwidth up to 10 times, which can
transmit up to 1000 mbps of data.
Wireless Network NIC
Wireless network NIC cards consist of a small antenna integrated onto the card, where
the communication between various devices is set up wirelessly using the router and
various network protocols. One such example of a wireless network NIC card is fiber
data digital interface FDDI. In a case where data has to be transmitted over long
distances, in such cases, a fiber data digital interface FDDI concept is used which
translates data into digital pulses and communicates using optical fiber.
Components of Network Interface Card
Network interface card components include the following:
1. Speed - All NICs have a speed rating in terms of Mbps that suggests the general
performance of the card when implemented in a computer network with
ample bandwidth. If the bandwidth is lower than the NIC or multiple computers are
connected with the same controller, this will slow down the labeled speed. The average
Ethernet NICs are offered in 10 Mbps, 100 Mbps, 1000 Mbps and 1 Gbps varieties.
2. Driver - This is the required software that passes data between the computer's operating
system (OS) and the NIC. When a NIC is installed on a computer, the
corresponding driver software is also downloaded. Drivers must stay updated and
uncorrupted to ensure optimal performance from the NIC.
3. MAC address - Unique, unchangeable MAC addresses, also known as a physical network
address, are assigned to NICs that is used to deliver Ethernet packets to the computer.
4.
Connectivity LED - Most NICs have an LED indicator integrated into the connector to
notify the user of when the network is connected and data is being transmitted.
5.Router - A router is also sometimes needed to allow communication between a computer
and other devices. In this case, the NIC connects to the router which is connected to the
internet.
Advantages of NIC




The communication speed using the internet is high usually in Gigabytes
Highly reliable connection
Many peripheral devices can be connected using many ports of NIC cards
Bulk data can be shared among many users
Disadvantages
 Inconvenient in case of wired cable NIC as it is not portable like a wireless
router
 The configuration should be proper for better communication
 Data is unsecured
NETWORK INTERFACE CARD INSTALLATION AND CONFIGURATION
Before proceeding to configuration, make sure that you installed the card properly.
Here’s how to do it!
1. First step is to read the user's guide and familiarize yourself with the new card.
2. Power down PC and remove the AC power cord.
3. Open the computer case.
4. Find an available Peripheral Component Interconnect (PCI) slot on the motherboard and
remove slot insert if one exists.
5. Carefully remove the network card from its staticproof plastic envelope, and slide it into the slot.
6. Seat the card in the slot firmly with gentle pressure
along the length of the card, especially right about
the slot itself.
7. Snugly, screw the card to the computer frame, but do not over tighten.
8. Close the computer case.
9. Plug your computer in and power it up.
10. Click Start, then click Control Panel.
11. In Category View (vs. Classic View) click Performance and Maintenance.
12. Click "System" icon at bottom of window.
13. Click the Hardware tab.
14. Click the Device Manager button.
15. Double-click Network Adapters.
16. Beneath it should appear the name of your Ethernet
card.
17. Next, double click the name of your Ethernet adapter.
18. If the text in the "Device Status" box says "This device is
working properly.", then you successfully installed the
card and are finished.
19. If the text in the "Device status" box doesn't say "This device is working properly.", then
write down on a piece of paper what it says and continue with next step.
20. Click the Troubleshoot. Button and follow instructions. Double check you followed the
directions above. Install the most up to date device drivers.
