Lecture TCP-IP protocol suite (3/e): Chapter 3 - Behrouz Forouzan

Chapter 3 - Underlying technology. Upon completion you will be able to: Understand the different versions of wired Ethernet, understand wireless Ethernet, understand the types of point-to-point WANs, understand the types of switched WANs, especially ATM, differentiate between repeaters, bridges, routers, and hubs. | Chapter 3 Objectives Upon completion you will be able to: Underlying Technology Understand the different versions of wired Ethernet Understand wireless Ethernet Understand the types of point-to-point WANs Understand the types of switched WANs, especially ATM Differentiate between repeaters, bridges, routers, and hubs TCP/IP Protocol Suite Figure 3.1 Internet model TCP/IP Protocol Suite 3.1 Local Area Networks A local area network (LAN) is a data communication system that allows a number of independent devices to communicate directly with each other in a limited geographic area such as a single department, a single building, or a campus. A large organization may need several connected LANs.The most popular LANs are Ethernet and wireless LANs. We briefly review these technologies in this section. The topics discussed in this section include: Wired LANs: Ethernet Wireless LANs: IEEE 802.11 TCP/IP Protocol Suite Figure 3.2 CSMA/CD TCP/IP Protocol Suite Figure 3.3 . | Chapter 3 Objectives Upon completion you will be able to: Underlying Technology Understand the different versions of wired Ethernet Understand wireless Ethernet Understand the types of point-to-point WANs Understand the types of switched WANs, especially ATM Differentiate between repeaters, bridges, routers, and hubs TCP/IP Protocol Suite Figure 3.1 Internet model TCP/IP Protocol Suite 3.1 Local Area Networks A local area network (LAN) is a data communication system that allows a number of independent devices to communicate directly with each other in a limited geographic area such as a single department, a single building, or a campus.

A point-to-point WAN connects two remote devices using a line available from a public network such as a telephone network. We discuss the physical .
