- 2. Target Competencies After this lesson module the student will be able to . . . ○ Understand the function of computer network. ○ Discuss how the computer network works. ○ Enumerate and explain the different devices use in computer networking. ○ Differentiate the types of computer network
- 3. TERMINOLOGIES NETWORK DIAGRAMS Basic layout/map of a computer networks NETWORK TYPES Computer types are base in shape and size. ○ WAN ○ LAN ○ MAN ○ PAN FIBER OPTIC CABLE One of the latest innovation in network cabling. SWITCHES & HUB The central device within a computer network that transmit data ROUTER Connects Modem to other device to allow communication from devices to the Internet.
- 4. TERMINOLOGIES MODEM Enable connection/communication with the internet. TOPOLOGIES refers the infrastructure of computer networks. FIREWALL Network software that keeps destructive forces and intruders from a computer network.
- 5. COMPUTER NETWORKS Computer network connects two or more autonomous computers. The computers can be geographically located anywhere.
- 6. COMPUTER NETWORKS Computer Network enable computer to communicate and transfer data and files from one computer to another. Computer Station 1 (SENDER) Computer Station 2 (RECEIVER) Computer Digital Data and File Transferring documents from computer station 1 to computer station 2
- 7. COMPUTER NETWORKS Computer networks can also create a group of computer networks. It uses a device called network switch / hub to connect all the computer station from one another to establish a group of network.
- 9. TYPES OF COMPUTER NETWORK ○ Local Area Network (LAN) ○ Wide Area Network (WAN) ○ Metropolitan Area Network (MAN) ○ Personal Area Network (PAN) ○ Peer-to-peer
- 10. TYPES OF COMPUTER NETWORK (1) Local Area Network (LAN) A local-area network (LAN) is a computer network that spans a relatively small area. Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.
- 11. TYPES OF COMPUTER NETWORK (1) Local Area Network (LAN) .
- 12. TYPES OF COMPUTER NETWORK (2) Wide Area Network (WAN) is a communications network that spans a large geographic area such as across cities, states, or countries. They can be private to connect parts of a business or they can be more public to connect smaller networks together.
- 13. TYPES OF COMPUTER NETWORK (2) Wide Area Network .
- 14. TYPES OF COMPUTER NETWORK (3) Metropolitan Area Network (MAN) is a series of LANs (Local Area Networks) that are interconnected in a Metropolitan area such as a city, region or country.
- 15. TYPES OF COMPUTER NETWORK (3) Metropolitan Area Network
- 16. TYPES OF COMPUTER NETWORK (4) Personal Area Network (PAN) interconnection of information technology devices or gadgets within the environment of an individual user.
- 17. TYPES OF COMPUTER NETWORK (4) Personal Area Network (PAN)
- 18. TYPES OF COMPUTER NETWORK (5) Peer-to-Peer Network Commonlyknown as P2P network. is created when two or more PCs are connected and share resources without going through a separate server computer. Each workstations has equivalent capabilities and responsibilities. Does not require switch or hub.
- 19. TYPES OF COMPUTER NETWORK (5) Peer-to-Peer Network
- 21. TECHONOLOGIES IN NETWORKING NETWORK SWITCH / HUB Used to connects various of network devices and computer to perform computer networking. A network device that channels incoming data from any of multiple input ports to the specific output port that will take it toward its intended destination.
- 22. TECHONOLOGIES IN NETWORKING MODEM A modem connects the source of your Internet from your ISP and your home network, whether you use a cable provider, like Comcast, fiber optics, like FIOS, satellite, such as Direct TV, or a DSL or dial-up phone connection. The modem connects to your router–or directly to your computer–using an Ethernet cable. Modems are different for each type of service; they are not interchangeable.
- 23. TECHONOLOGIES IN NETWORKING ROUTER Network device that join multiple computer networks together via either wired or wireless connections. It also connects two or more networks and that the router operates at the network layer of the OSI model.
- 24. TECHONOLOGIES IN NETWORKING ETHERNET CABLE A cable use to connect your computer and network devices. Ethernet cables resembles a phone cable but are larger and feature more wires. Both cables share a similar shape and plug but an Ethernet cable has eight wires and a larger plug than the four wires found in phone cables.
- 25. TECHONOLOGIES IN NETWORKING REPEATER Network device used to regenerate or replicate a signal. It extend the coverage area of your WiFi network. It works by receiving your existing WiFi connection, amplifying it and then transmitting the boosted signal. With this network device you can boost the signal and effectively double the coverage area of your WiFi network.
- 27. Your are using your computer accessing the internet
- 28. Your computer will gather data and information via digital signals (computer data) through Ethernet cable ETHERNET CABLE
- 29. If your computer is belong from a group of network the Ethernet is connected from your computer to a network switch. NETWORK SWITCH ETHERNET CABLE
- 30. If your computer is not belong to a group of computer network the data and information is directly pass through your router and modem. Router & Modem ETHERNET CABLE
- 31. If your computer is not belong to a group of computer network the data and information is directly pass through your router and modem. Router & Modem ETHERNET CABLE NETWORK SWITCH ETHERNET CABLE
- 32. Modem Router is provided by your chosen Internet Service Provider (ISP) for you to access and connect with the Internet.
- 33. Internet Service Provider in the Philippines 1. PLDT 2. SKY BROADBAND 3. CONVERGE ICT 4. BAYANTEL 5. SMART/SUN 6. GLOBE 7. INNOVE 8. EASTERN TELECOM 9. WI-TRIBE 10. DESTINY CABLE INTERNET
