    Study Notes

    Network Components

    • Networks can be simple, connecting two computers with a cable, or complex, spanning the globe.
    • Networks are made up of three categories of components: devices, media, and services.
    • End devices originate or receive data, such as computers, phones, and tablets.
    • Intermediary devices connect end devices and manage data flow in a network. Examples include: switches, wireless access points, routers, and firewalls.
    • Network media carries communication across a network, allowing messages to travel from source to destination.
    • Network media includes metallic wires within cables (copper), glass (fiber optic cables), and wireless transmission.
    • Network diagrams use symbols to represent devices, including the Network Interface Card (NIC), physical ports, and interfaces.

    Network Types

    • Common network types include: Local Area Networks (LANs), Wide Area Networks (WANs), Metropolitan Area Networks (MANs), Wireless LANs (WLANs), and Storage Area Networks (SANs).
    • LANs span a small geographic area such as a home, office, school, or campus.
    • LANs are usually administered by a single organization or individual.
    • LANs provide high-speed bandwidth to devices within the network.
    • WANs interconnect LANs over wide geographical areas such as between cities, states, or countries.
    • WANs are usually administered by multiple service providers.
    • WANs typically provide slower speed links between LANs.

    The Internet

    • The Internet is a global collection of interconnected LANs and WANs.
    • LANs are connected using WANs, and WANs are connected using copper wires, fiber optic cables, and wireless transmissions.
    • The Internet is not owned by any individual or group, but groups like the IETF, ICANN, and IAB help maintain its structure.

    Intranets and Extranets

    • Intranets are private collections of LANs and WANs internal to an organization, accessible only to authorized members.
    • Extranets provide secure access to an organization's network for individuals outside the organization who need access to data.

    Internet Access Technologies

    • Popular Internet access technologies for home and small offices include broadband cable, DSL, wireless WANs, and mobile services.
    • Organizations often use business-class interconnections, such as business DSL, leased lines, and Metro Ethernet, to support IP phones, video conferencing, and data center storage.

    Reliable Networks

    • Multiple paths are required in networks for fault tolerance.
    • Packet switching networks allow each data packet to potentially take a different path to the destination, increasing reliability.
    • Circuit-switched networks establish dedicated circuits, preventing packet routing flexibility.
    • Scalable networks expand quickly and easily to handle new users and applications without impacting existing users.
    • Network designers follow accepted standards and protocols to ensure network scalability.
    • Quality of Service (QoS) is a mechanism used to ensure reliable delivery of content across a network.
    • QoS policies allow routers to manage data and voice traffic flow.
    • BYOD allows end users to use personal devices like laptops, netbooks, tablets, smartphones, and e-readers to access information and communicate on the network.
    • Online collaboration tools, such as Cisco WebEx, enable individuals to connect, interact, and work on joint projects over the network.
    • Cloud computing allows users to store files, back up data, and access applications, like word processing and photo editing, on servers over the Internet.
    • Cloud computing enables businesses to expand capabilities on demand and deliver services to any device.
    • Cloud computing utilizes data centers, allowing smaller companies to lease server and storage services from larger organizations.
    • Three types of clouds exist: public clouds, private clouds, and hybrid clouds.
    • Public clouds offer services and applications to the general public through a pay-per-use model or for free.
    • Private clouds are for specific organizations or entities, such as a government.
    • Hybrid clouds combine elements of both public and private clouds.
