TAILIEUCHUNG - Lecture Wireless and mobile computing – Chapter 11: Communication networks

The following will be discussed in this chapter: LANs WANs differentiation, path reliability, circuit switching driven example network, circuit switching routing types, semi-permanent connection type, isdn review question, datagram and virtual circuit operational differentiation, limitations of circuit switching for data transmission, virtual channel and virtual path difference. | Communication Networks Review Question/Answer Lecture 11 1 Overview LANs WANs Differentiation Path Reliability Circuit Switching Driven example network Circuit Switching Routing Types Semi-Permanent Connection Type ISDN Review Question Datagram and Virtual Circuit Operational Differentiation Limitations of Circuit Switching for Data Transmission Virtual Channel and Virtual Path Difference 2 WANs and LANs Q:-Differentiate between WANs and LANs 3 High Speed WANs and LANs Scope of High Speed LANs and WANs (backbone) WANs and LANs scope in case of wireless communication (Mobility) 4 Overview of Wireless LANs wireless transmission medium issues of high prices, low data rates, occupational safety concerns, & licensing requirements now addressed key application areas: LAN extension cross-building interconnect nomadic access ad hoc networking 5 5 Single Cell LAN Extension 6 6 Multi Cell LAN Extension 7 7 Cross-Building Interconnect 8 8 Nomadic Access also useful in extended environment such as campus or cluster of buildings users move around with portable computers access to servers on wired LAN 9 9 Infrastructure Wireless LAN 10 10 Ad Hoc Networking temporary peer-to-peer network 11 11 Wireless LAN Requirements 12 12 Wireless LANs 13 13 WAN MAN and LAN Q:-Differentiate between WANs and LANs Ans:- Wide area networks (WANs) are used to connect stations over very large areas that may even be worldwide while local area networks (LANs) connect stations within a single building or cluster of buildings. Ordinarily, the network assets supporting a LAN belong to the organization using the LAN. For WANs, network assets of service providers are often used. LANs also generally support higher data rates than WANs. 14 15 Q:-Differentiate between WANs and LANs Ans:- Wide area networks (WANs) are used to connect stations over very large areas that may even be worldwide while local area networks (LANs) connect stations within a single building or cluster of buildings. Ordinarily, the .
