Outline Introduction of home networking Home networking technologies Choosing operating system for home networking Conclusion 4/28/2019
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. 4/28/2019
Introduction (cont’d) Why home networking? Share peripheral devices such as printers, Zip drive. Transfer data from one PC to another Share Internet services via single fast Internet connection 4/28/2019
Introduction (cont’d) Driving forces for home networking Home based small businesses 13 million or 12.6 percent of all US residents hold a business PC-Based households 9.4 million households have two or more PCs Non-PC devices that require networking Smart appliances, home-security systems 4/28/2019
Introduction (cont’d) Key requirements for home network Easy to install and less Maintenance Cost effective Reliability 4/28/2019
Home networking technologies 1. Wired home network 2. Wireless home network 4/28/2019
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 4/28/2019
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 4/28/2019
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 4/28/2019
Choosing operating systems for home network Linux Unix NT Win95 Mac OS/2 Printer Services y File server/sharing N Mail server X Domain name server Web Server Firewall Routing Gateway Internet ISDN TCP/IP NFS y Support in system as supplied x Support available as extra N Support not available 4/28/2019
Picking an operating system Windows NT/2000 Graphic User Interface (GUI) Expensive Windows 95/98 Limited networking Need additional software to perform server functions Often crashes 4/28/2019
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 4/28/2019
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 4/28/2019
Home networking with Linux Provide mail server allowing as many e-mail 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 4/28/2019
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. 4/28/2019
