The CMTS encapsulates the CPE traffic from mapped cable modems using VLAN tags, as defined in IEEE Q, IEEE Standards for Local and Metropolitan Area Networks: Virtual Bridged Local Area Networks.

The switch acting as the Layer 2 Bridge Aggregator uses the VLAN tagging to forward the packets to the appropriate destination. CCNA 4 Chapter 1 Exam Answers v v v v v Questions Answers % Update - - Latest version Connecting Free Download/5(11).

Wireless Local Area Network: A LAN based on Wi-Fi wireless network technology.; Metropolitan Area Network: A network spanning a physical area larger than a LAN but smaller than a WAN, such as a city.A MAN is typically owned and operated by a single entity such as a government body or large corporation.

Metropolitan Area Network: A metropolitan area network (MAN) is similar to a local area network (LAN) but spans an entire city or campus. MANs are formed by connecting multiple LANs. Thus, MANs are larger than LANs but smaller than wide area networks (WAN).

MANs are extremely efficient and provide fast communication via high-speed carriers. William Shieh, Ivan Djordjevic, in OFDM for Optical Communications, Publisher Summary.

High bandwidth demands in metropolitan area networks (MANs) and requirements for flexible and cost-effective service cause the imbalance known as the “last mile bottleneck.” Fiber optics, RF, and copper/coaxial lines are the main state-of-the-art technologies used to address the high.

over distances of a few hundred feet. A WMAN is a metropolitan area network that uses radio signals to transmit and receive data, and a WWAN is a wide area network that uses radio signals to transmit and receive data.

Learning Outcome. Data Communication and Computer Network 5 Backbone of MAN is high-capacity and high-speed fiber optics. MAN works in between Local Area Network and Wide Area Network. MAN provides uplink for LANs to WANs or internet.

Wide Area Network As the name suggests, the Wide Area Network (WAN) covers a wide area which may. A communications technology aimed at providing high-speed wireless data over metropolitan area networks Created as an alternative to cable and dsl Based on IEEE NOTE: Typically used for rural areas Wireless MAN.

A network is defined as a group of two or more computer systems linked together. There are many types of computer networks, including the following.

local-area networks (LANs): The computers are geographically close together (that is, in the same building). wide-area networks (WANs): The computers are farther apart and are connected by telephone lines or radio waves.

Used technologies can also vary from 3G wireless communication channels to broadband PLC, optical fiber, wireless radio, etc. Wide-area networks provide transparent links between the metering infrastructure installed on sites and the MDC system, being the infrastructure base of the set of machine-to-machine (M2M) services built on top of them.

Basic Networking Tutorial - a network is any collection of independent computers that communicate with one another over a shared network medium.A computer network is a collection of two or more connected computers.

When these computers are joined in a network, people can share files and peripherals such as modems, printers, tape backup drives, or CD-ROM drives. Network: A network, in computing, is a group of two or more devices that can communicate.

In practice, a network is comprised of a number of different computer systems connected by physical and/or wireless connections. The scale can range from a single PC sharing out basic peripherals to massive data centers located around the World, to the.

Internet access is the ability of individuals and organizations to connect to the Internet using computer terminals, computers, and other devices; and to access services such as email and the World Wide et access is sold by Internet service providers (ISPs) delivering connectivity at a wide range of data transfer rates via various networking technologies.

Chapter Description. What is the purpose of a WAN. In this sample chapter from Connecting Networks v6 Companion Guide, explore how wide-area networks (WANs) operate, what services are available, the differences between private and public WAN technologies, and more.

Security risks are incurred when a teleworker or a remote office worker uses a broadband service to access the corporate WAN over the Internet.

To address security concerns, broadband services provide capabilities for using VPN connections to a network device that accepts VPN connections, which are typically located at the corporate site.

A wide area network (WAN) is a telecommunications network that extends over a large geographical area for the primary purpose of computer area networks are often established with leased telecommunication circuits.

Business, as well as education and government entities use wide area networks to relay data to staff, students, clients, buyers and. Internetworks. Before discussing about the terms internet, intranet and extranet, we need to discuss the term Internetwork.

An internetwork can be defined as two or more computer networks (typically Local Area Networks LAN) which are connected together, using Network Routers.

Each network in an Internetwork has its own Network Address, which is different from other. There are three primary categories of networks: wireless local area network (WLAN), wireless metropolitan-area network (WMAN), and wireless personal area network (WPAN). The security for. Network Address Translation (NAT) is a service that can be supplied by a router or by a server.

The device that provides the service stands between the local LAN and the Internet. When packets need to go to the Internet, the packets go through the NAT service first. This chapter uses the following key terms. You can find the definitions in the glossary at the end of the book.

Computer networks support an enormous number of applications and services such as access to the World Wide Web, digital video, digital audio, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications as .A Practical Introduction to Enterprise Network and Security Management contains 12 chapters of the correct amount of coverage for a semester or quarter.
