    Study Notes

    What is SOHO?

    • SOHO stands for Small Office/Home Office
    • These networks enable people to work remotely
    • Many self-employed workers use SOHO networks to operate businesses
    • Large organizations use networks to centralize data storage and access

    Types of Networks

    • Peer-to-peer networks are commonly used in small businesses and homes where individual computers act as both servers and clients
    • LAN (Local Area Network): connects devices in a small geographical area like a home, office, or school
    • WAN (Wide Area Network): connects networks across a wide geographical area, typically owned and managed by large corporations or telecommunications providers

    Extranets

    • Provide secure access for individuals from different organizations who need access to data
    • Examples: companies providing access to suppliers and contractors, hospitals providing appointment systems to doctors, schools providing budget and personnel information to districts

    Internet Connections

    • ISP (Internet Service Provider): provides internet access to home users, remote workers, and small offices
    • Broadband Cable: high-bandwidth, always-on connection using the same cable as cable television
    • DSL (Digital Subscriber Line): high-bandwidth, always-on connection over telephone lines with faster download speeds than upload speeds
    • Cellular: internet access using a cell phone network with performance limited by the phone and cell tower capabilities
    • Satellite: internet access via satellite dishes useful in areas without wired connectivity but requires a clear line of sight to the satellite
    • Dial-up Telephone: low-bandwidth connection using a modem and phone line suitable for mobile access but not large data transfers

    Business Internet Connections

    • Businesses require higher bandwidth, dedicated bandwidth, and managed services
    • Dedicated Leased Line: reserved circuits within a service provider’s network used for private voice or data networking between geographically separated offices
    • Metro Ethernet: extends LAN access technology into the WAN, enabling business broadband connection
    • Business DSL: various formats available, with SDSL (Symmetric Digital Subscriber Line) providing high-speed upload and download speeds for businesses

    Converging Networks

    • Traditional Separate Networks: separated data, telephone, and video networks using different technologies and standards
    • Converged Networks: combine data, voice, and video communication on a single network infrastructure with shared rules and standards

    Reliable Networks

    • Network Architecture: refers to technologies supporting the infrastructure and protocols that govern data movement across the network
    • Fault Tolerance: building networks to limit the number of affected devices during failures and enabling quick recovery
    • Redundancy: having multiple paths between source and destination for data transmission to ensure communication even if one path fails
    • Scalability: the ability of a network to grow and accommodate increased users, devices, and data traffic without significant performance degradation
    • Quality of Service (QoS): prioritizing data traffic to ensure critical applications and services receive optimal performance

    BYOD (Bring Your Own Device)

    • Any device, with any ownership, used anywhere

    Online Collaboration

    • Collaboration tools: allow individuals to connect, interact, and achieve objectives through instant messaging, video conferencing, and file sharing
    • Cisco WebEx: a widely used collaboration tool

    Video Communications

    • Video calls and conferencing enable communication across geographic and cultural boundaries
    • Video conferencing is a powerful tool for collaboration and communication within organizations

    Cloud Computing

    • Data Centers: facilities housing computer systems and associated components
    • Cloud computing enables:
      • Storing personal files and backing up entire drives over the internet
      • Accessing applications like word processing and photo editing remotely
      • Extending IT capabilities for businesses without requiring investments in new infrastructure, training, or software
