4. COMPUTER NETWORK is a group of computers connected with each other through transmission cables and wires. A network is a collection of computers and related equipment (printers, webcams, game consoles, etc.) connected so that data can move between them. The Internet, then, is a network of networks.

5. LESSON OBJECTIVES Identify the Computer Network and Network Topology. 1 2 3 Illustrate the different Network Topology. Value the importance of choosing the appropriate topology on a network.

6. Identify the given type of network: - LAN (Local Area Network) - WAN (Wide Area Network) - MAN (Metropolitan Area Network)

7. Local Area Network C omputers in this network are connected with each other in small places such as school, hospital, apartment etc. It is secure because there is no outside connection with the local area network thus the data which is shared is safe on the local area network and can’t be accessed outside. It is due to their small size being considerably faster, their speed can range anywhere from 100 Kbps to 100Mbps. LANs are not limited to wire connection, there is a new evolution to the LANs that allows local area networks to work on a wireless connection.

8. Metropolitan Area Network C overs a larger area by connecting LANs to a larger network of computers. In the Metropolitan area network various Local area networks are connected with each other through telephone lines. The size of the Metropolitan area network is larger than LANs and smaller than WANs (wide area networks), and MANs covers the larger area of a city or town. It's a network that spans no more than 50 miles.

9. Wide Area Network This network provides long distance transmission of data. The size of the WAN is larger than LAN and MAN. A WAN can cover a country, continent or even a whole world. Internet connection is an example of WAN. Other examples of WAN are mobile broadband connections such as 3G, 4G etc. It is used to distribute information thousands of miles among thousands of users.

10. Two categories in the network topology: 1. Physical – The physical network topology refers to the actual connections (wires, cables, etc.) of how the network is arranged. Setup, maintenance, and provisioning tasks require insight into the physical network. 2. Logical – The logical network topology is a higher-level idea of how the network is set up, including which nodes connect to each other and in which ways, as well as how data is transmitted through the network. Logical network topology includes any virtual and cloud resources.

11. Common Type of Physical Topology: Star Topology - the most common network topology, is laid out so every node in the network is directly connected to one central hub via coaxial, twisted-pair, or fiber-optic cable. Acting as a server, this central node manages data transmission—as information sent from any node on the network has to pass through the central one to reach its destination—and functions as a repeater, which helps prevent data loss.

12. Common Type of Physical Topology: EXTENDED STAR TOPOLOGY

13. Common Type of Physical Topology: Bus Topology - orients all the devices on a network along a single cable running in a single direction from one end of the network to the other—which is why it’s sometimes called a “line topology” or “backbone topology.” Data flow on the network also follows the route of the cable, moving in one direction.

14. Common Type of Physical Topology: Ring topology - is where nodes are arranged in a circle (or ring). The data can travel through the ring network in either one direction or both directions, with each device having exactly two neighbors.

15. Common Type of Physical Topology: Tree Topology - structure gets its name from how the central node functions as a sort of trunk for the network, with nodes extending outward in a branch-like fashion. However, where each node in a star topology is directly connected to the central hub, a tree topology has a parent-child hierarchy to how the nodes are connected.

16. Common Type of Physical Topology: Mesh Topology - is an intricate and elaborate structure of point-to-point connections where the nodes are interconnected.

17. Common Type of Physical Topology: Hybrid Topology - combine two or more different topology structures—the tree topology is a good example, integrating the bus and star layouts. Hybrid structures are most commonly found in larger companies where individual departments have personalized network topologies adapted to suit their needs and network usage.

18. ACTIVITY 1: TOPOLOGY Directions: Study the given topology & a nswer the following questions. What’s the difference between physical and logical topology? Which Physical Topology is best? Why? Which Physical Topology is the least functional? Explain.
