PowerPoint presentation on network transmission media

1. Network transmission media

2. Introduction Data transmission media are the paths that carry data from one device to another. They are divided into two types: Wired Transmission Media Wireless Transmission Media

3. Overview of Wired Transmission Media Wired media use physical cables to transmit data. Examples include: Twisted Pair Cable Coaxial Cable Fiber Optic Cable Ethernet-like Cable symbol Light beam

4. Twisted Pair Cable Internal Components: • Pairs of copper wires twisted together • Insulation Merits: • Low cost • Easy to install Demerits: • Limited bandwidth • Susceptible to interference Ethernet-like

5. Coaxial Cable Internal Components: • Copper conductor • Insulating layer • Metallic shield • Outer insulation Merits: • Better shielding than twisted pair • Higher bandwidth Demerits: • Bulkier • More expensive than twisted pair Cable symbol

6. Fiber Optic Cable Internal Components: • Core (glass/plastic fibers) • Cladding • Protective coating Merits: • Extremely high bandwidth • Immune to electromagnetic interference Demerits: • Expensive • Fragile and harder to install Light beam

7. Overview of Wireless Transmission Media Wireless media transmit data without physical cables. Examples include: • Wi-Fi • Bluetooth • Cellular Networks • ZigBee • Near Field Communication (NFC) • RFID • Satellite Communication • Infrared (IR) • Ultra-Wideband (UWB) Wi-Fi waves B symbol Tower Mesh icon Contactless icon Radio waves Satellite dish Remote icon Wide waves

8. Wi-Fi High-speed wireless networking for LANs. Wi-Fi waves

9. Bluetooth Short-range communication between devices. B symbol

10. Cellular Networks Mobile communication using cell towers. Tower

11. ZigBee Low-power wireless mesh for IoT devices. Mesh icon

12. Near Field Communication (NFC) Very short-range communication (payment systems). Contactless icon

13. RFID Radio tags for tracking and identification. Radio waves

14. Satellite Communication Long-distance communication via satellites. Satellite dish

15. Infrared (IR) Short-range line-of-sight communication. Remote icon

16. Ultra-Wideband (UWB) High data-rate, short-range communication. Wide waves

17. Comparison: Wired vs Wireless Wired: • Stable and high speed • Secure • Requires physical installation Wireless: • Convenient and flexible • Easier to expand • May suffer interference and lower speed
