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
