Chapter 6. WAN Technologies Internet Access, and Security Protocols

Objectives

2.14 Identify the basic characteristics (for example, speed, capacity, and media) of the following WAN (wide area network) technologies:

• Packet switching

• Circuit switching

• ISDN (Integrated Services Digital Network)

• FDDI (Fiber Distributed Data Interface)

• T1 (T Carrier level 1)/E1/J1

• T3 (T Carrier level 3)/E3/J3

• OCx (Optical Carrier)

• X.25

2.15 Identify the basic characteristics of the following Internet access technologies:

• xDSL (Digital Subscriber Line)

• Broadband Cable (Cable modem)

• POTS/PSTN (Plain Old Telephone Service/Public Switched Telephone Network)

• Satellite

• Wireless

2.16 Define the function of the following remote access protocols and services:

• RAS (Remote Access Service)

• PPP (Point-to-Point Protocol)

• SLIP (Serial Line Internet Protocol)

• PPPoE (Point-to-Point Protocol over Ethernet)

• PPTP (Point-to-Point Tunneling Protocol)

• VPN (Virtual Private Network)

• RDP (Remote Desktop Protocol)

2.17 Identify the following security protocols and describe their purpose and function:

• IPSec (Internet Protocol Security)
