3. Introduction What is home networking?
The collection of elements that process, manage, transport, and store information, enabling the connection and integration of computing, controlling, monitoring, and communication devices in the home.
Two or more computers interconnected to form a local area network (LAN) within home.

8. 1. Wired home network
Twisted Copper-Pair or Coaxial-Based Transport Systems (Ethernet)
Most widely installed LAN technology
Requires network interface card (NIC)
High speed (10 Mbps to 100 Mbps)
High reliability
Expensive

9. 1. Wired home network (cont’d)
Twisted Copper-Pair-Based Systems (Phone Line)
Based on existing phone lines
Relatively low speed ( 1 Mbps to 10 Mbps)
Alternating Current Power line-Based Transport Element
Readily available power line
Send and receive frequency based control, monitoring and communications signals to smart devices

10. 2. Wireless home network The Radio Frequency (RF) Transport Network
Use RF waves to transmit through walls and floors
Bring in incomparable mobility
Limited range(800 feet)
Low speed (2 Mbps)
Potential interference from other wireless devices

13. Picking an operating system
Linux
Network friendly
Open source (free)
Support different computer architectures
Reliable
Simple
Unix
Well established
Designed for network
Reliable
Relatively complex
Expensive

14. Home networking with Linux
Runs on any 386/486/586/Pentium, Dec Alpha, Sun SPARC and MIPS.
Support most protocols.
Provide a gateway to the internet for the rest of PCs.
Provide firewall service to protect the network

15. Home networking with Linux
Provide mail server allowing as many
addresses as required
Provide printer and file server functions
Provide NFS (mount disk drives on remote
machines) service at distribution
Provide web-server and Java development system

16. Conclusions Home networking is expected to grow in the near future
Exciting wireless technology makes home network more mobile and flexible
Linux is an extremely capable operating system for home networking being one of the least expensive yet the most powerful.
