2. Learning Competencies
At the end of this learning module the students will be able to . . .
○ Discuss the client and servers functions in computer networking.
○ Understand the concept of Network Protocol
○ Enumerate and classify computer networking topologies.

3. Networking Media
Networking media can be defined simply as the means by which
signals (data) are sent from one computer to another (either by
cable or wireless means).

4. CLIENT AND SERVER
In a client/server network arrangement, network services are
located in a dedicated computer whose only function is to
respond to the requests of clients.
The server contains the file, print, application, security, and other
services in a central computer that is continuously available to
respond to client requests.

5. NETWORKING PROTOCOL (TCP/IP)
Network protocols are formal standards and policies comprised
of rules, procedures and formats that define communication
between two or more devices over a network. Network protocols
govern the end-to-end processes of timely, secure and managed
data or network communication.

6. PROTOCOL CONCEPTS
○ Set of rules
○ What do you want to do? (Application)
○ Where are you going? (Addressing)
○ How do you get there? (Media Types)
○ Did you get there? (Error Checking)

7. Computer Networking Models
Models, also called protocol stacks, represented in layers, help to
understand where things go right or wrong.

8. Network Topologies
Network Topology refers to the shape of a network, or the
network's layout. How different nodes in a network are connected
to each other and how they communicate are determined by the
network's topology.

9. RING TOPOLOGY
All the nodes are connected to each-other in such a way that they
make a closed loop. Each workstation is connected to two other
components on either side, and it communicates with these two
adjacent neighbors.

10. STAR TOPOLOGY
The most commonly used network topology. All the network nodes
are individually connected to a central switch, hub or computer
which acts as a central point of communication to pass on the
messages.

11. STAR TOPOLOGY
The most commonly used network topology. All the network nodes
are individually connected to a central switch, hub or computer
which acts as a central point of communication to pass on the
messages.

12. FULLY CONNECTED / MESH TOPOLOGY
All the network nodes are connected with one another to perform
data communication. Every computer in the network has a
connection to each of the other computers in that network.

13. BUS TOPOLOGY
is a network setup in which each computer and network device are
connected to a single cable or backbone.

14. LINE TOPOLOGY
In this system, data is sent to all nodes on the network at the same
time. Devices are positioned along a line.

15. TREE TOPOLOGY
it is a combination of two or more star networks connected
together. Each star network is a local area network (LAN) in which
there is a central computer or server to which all the workstation
nodes are directly linked.
