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
