I  Concepts & Terms Required - Chapter 0111

The process of connecting to remote networks is vital in today’s business world. The interface between this type of network communication and the Internet is at once both interesting and unnecessarily complicated. Understanding the development of this form of networking will aid us comprehending the process of remote connection. We shall attempt to demystify the process and look at the various pros and cons of remote communication.

There are two basic types of remote communication which occur – those connecting multiple LAN’s (local area networks) into a large WAN (wide area network) over very high-speed networking lines, and those connecting single remote users to a main corporate site or an ISP’s (Internet Service Provider’s) Internet link over slower dial-up and broadband technologies.

Both of these are important for the Network+ exam, so first we’ll look at single user or SOHO “remote access” scenarios, and then we’ll move to network-to-network WAN connectivity.

  • Understand the purpose and functionality of Remote Access

  • Know the low-speed dial-up access options and their characteristics

  • Know the high-speed network connectivity options for individuals, and the characteristics of those options

  • Know the high-speed network-to-network connectivity options and the characteristics of them

  • Understand the purpose of encapsulation protocols such as SLIP, PPP, PPTP, L2TP and PPPoE
