Describe how a network works

    • A successful PINGing of a host exhibits the connectivity through layers 1, 2, and 3 of an OSI network model.
    • Simple Mail Transfer Protocol (SMTP) and Telnet are application layer protocols of the Internet protocol (IP) suite.
    • Cable modem is used to connect a CATV cable to a computer/router through an Ethernet interface.
    • A Wireless Access Point (WAP) is used to connect wireless hosts to a wired LAN.
    • The Gigabit Ethernet (1000Base-LX) standard supports a maximum cable length of 5000 meters.
    • The 1000Base-LX/SX Ethernet types use fiber cables.
    • The Session layer of the OSI model manages communication between communication entities in a network.
    • The Session layer of the OSI model provides dialog management and assists the upper layers in connecting to services on the network.
