Access Network

1. Computer Networks Presentation Presented To Md. R ayhan I slam D epartment of CSE Presented By Mominul Islam 192-15-13156 Section: EVE_211_DSC Daffodil International University Access Networks

2. Introduction to Access Networks Access networks are the communication networks that connect end-user devices, such as computers, smartphones and tablets, to a wide area network (WAN), such as the internet. More example: ISP, home networks, enterprise networks, ADSL, mobile network, FTTH etc

3. Types of Access Networks Wired: Ethernet, DSL, FTTH Wireless: Satellite Internet, 3G & LTE, WiMAX, 5G, Wi-Fi, Bluetooth, Wi-Fi Direct

4. Importance of Access Networks Crucial for modern telecommunications Enables fast data transfer and reliable communication Supports high-speed transfers and secure voice/video conferencing Reduces costs associated with long-distance communication Efficiently handles large traffic volumes Facilitates global expansion through fiber optics or satellite links

5. Working Principle of Access Networks Devices needed to connect (modem, router, switch) Connection technologies: DSL, Ethernet, Wi-Fi, 5G Internal routing protocols (e.g., Internet Protocol) Features such as quality of service (QoS)

6. The Bottom Line Access networks connect users to the internet, offering a range of technologies like DSL, cable, fiber-optic, and wireless to meet various connectivity needs. They enable digital inclusion, support the digital economy, and addressing challenges such as infrastructure costs, scalability, and security.

7. Have a good day , thank you!
