HOME  NETWORK

Creating a home network.

 

For houses with many members. And use almost all computers. We are able to build up a home network. Then connect all the computers together. To be able to exchange information between each other and access the Internet just an single county.Network technology in the home.Because the home is the wiring. Telephone line out already. It can be something that is available to make the network. Eliminating the need for new cabling. Home network technologies can be divided into the following five together.• Ethernet network technology, a Bus.• The Ethernet Technology Network Star.• phone line networking technology.• powerline networking technology.• The wireless network technology.Networking technology for Ethernet Bus.Network technology, Ethernet and Bus Mult 10Base2 using the Coaxial (cattle Pontiac special) called Thin Coaxial cable or RG-58 (with a resistance of 50 ohms), the overall length of the line from the origin to the destination machine. must not exceed 180 meters, but the model is low cost because it does not require a hub in the middle - a signal.Ethernet network technology, a Star.Network technology, Ethernet and Star as standard 10BaseT is a form of wired UTP (Unshield Twisted Pair), which is a small line within eight strands twisted together four pairs in the - in the Speed ​​10/100 Mbps with a signal. Base band and the length of each cable line from the hub must not exceed 100 feet (80 meters should be a good way to avoid interference).Connection is suitable for home use because it can be easy to move the machine and disconnect the Island. As for the cost, since it is very inexpensive 8-port hubs are around 1,000 baht.Telephone network technologies.Telephone network or telephone lines went Phoneline Network is bringing them home. The connection between computers.Usually it will be phone wiring in every room in the house. We just put a network adapter. Used for connecting to a phone line to plug into. The computer can use it.Know HomePNA.Organization that looks after the network using standard phone lines will be called HomePNA trusted name www.homepna.org. A source of information about the products used to connect network phone lines in Figure 5.5 transfer speeds - Send information about 10 megabits per second T (10 Mbps) as the technology to be used for qualified Inernet Gateway as the other systems.Network cables.Network wiring (Powerline Network) or Power Line Communication. Is bringing the power lines went inside to get laid - send data.(User must have a device converts the data from the signal generator) power line networking technology can be - in both the large data files. Including high speed internet surfing 5.4 megabits per second. (On the modem speed is about 56 kilobytes per second), the basic operation of electric network. When the signal is high frequency information from the Internet, which he would send a signal to the local power station. To supply electricity to every home. Users will need a special adapter for plugging into an outlet at home. Then converted - Field signal in both picture and sound from the electrical signals. Then send them to the computer or other electrical unit used to.Organizations controlled using standard network cables is HomePlug Powerline A lliance by combining the different device manufacturers leading networks such as AMD, CISCO, Compaq, Intel, Motorola, 3COM, etc. have a site name.www.homeplug.org.The Company's technology is designed Intellon chip (Chip) for embedded computers. And other electrical components of Figure 5.8 to see how technology Intellon Homeplug 1.0 Compliant with speeds up to 14 megabits per second.Wireless network technology.Wireless network (Wireless) has developed a range of more than five years for the greater good. Do not want to clutter the wiring Portland meeting room VIP customers park or area. Land can not be hardwired.But we take the computer to the user in a broadcast radius. It has a radius ranging from 80 to 400 feet of wireless network technology are two different types.First.HomeRF (Home Radio Frequency).Two. IEEE 802.11.HomeRF (Home Radio Frequency) is the product of the Group Cayman System, Compaq Ciemens, Intel, Motorola, and Proxim, designed for use at home. Allows us to carry a notebook to work in any room in the home. Or to sit the E-mail and the Internet to find information on home turf it. Land lines are no longer interested in the silk cloth? Because HomeRF systems use frequency 2.4 GHz (Ka Chi Hz) for penetrating walls wall obstacles. In the - information. This system has a radius of about 150 feet with speed - Transfer files to 10 megabits per second by the HomeRF 2.0.IEEE 802.11b was designed and developed by the Institute of Electrical and Electronic Engineers (IEEE or the I triple E) network is known as IEEE 802.11b Wireless LAN (WLAN) uses radio frequency 2.4 GHz (. shift registers Hz) for - information. This system will have a radius of about 80 to 300 feet from the access point. Or it may be up to 100 meters high - in file 11 megabits per second. Network Wireless Wireless LAN is composed of two parts: the Access Point (access points) and PC cards by the second part is to receive - signal frequency 2.4 GHz agencies have tested and approved these products. the WECA (Wireless Ethernet Compatibility Alliance) has a website www.wi-fi.com. For in wallpaper form. There are two companies involved in the chip design of the two companies.Security. Receiving - IEEE 802.11b wireless data transmission, there are likely to be intercepted. Capture data as well. So before you get products WiFi security checks. Which is the standard WEP (Wired Equivalent Privacy) is a data encryption (Data Encryption) and 40 to 64-bit and 128-bit encryption to secure the data.Wireless LAN Speed ​​5 GHz.IEEE 802.11b wireless networking is gaining speed - 5 to 11 megabits per second data transmission and data encryption. There are many manufacturers of the United States and European countries began to develop design standards IEEE 802.11a, which uses radio frequencies 5 GHz (Ka Chi Hz), the material can transmit data at a speed of 22 to 72 MHz. bits per second and supports Quality of Service for multimedia applications such as video with sound.Because the manufacturer states to use 802.11b standard, which is similar to the Ethernet system is Listen before Transmitting or listen before, but use European standard HIPERLAN / 2 in the time slot will be similar to the ATM. difference between the two standards will cause problems for users of the equipment is not available for use in the U.S., Europe and the United States. I can not take it.Equipment in use in Europe as well.
