Fascinating Facts About Telephone Technology and Networks... 

A third use of radio transmissions is in local area networks. A radio transmission connects a device attached to a telephone line and a computer. Frequently, this is identified as Wi-Fi. Although the technology is different, a cordless telephone operates in much the same way. 

Phase 5 Multiple CPUs And Intelligent Laboratory Devices On The Network. Computer manufacturers have developed systems with multiple CPUs and multiple operating systems (i.e. A Network). The construction of networks comprised completely of intelligent laboratory devices is a real possibility with the availability of the Ethernet Specification. Small local area networks of laboratory deices will develop using Ethernet and other technologies. Later these local networks will be interconnected probably via routers and gateways to broadband, Satellite, and telephone facilities. 

You can gain access to the Internet either through a LAN at your place of work or from home via a modem connected to a dial-in service provider over the telephone line. You do not need to understand the technology of the network to use it - most of it is invisible to the user. However, if you do wish to understand more, sources such as Gralla (1996) and Winship and McNab (2000) are recommended. What you do need to know are the options available to you in terms of using its facilities and their relative merits or disadvantages. You also need to understand a little about the nature of Internet addresses. 

Before we can discuss connecting Windows to the Internet, we need to discuss the Internet itself. There are some common terms and concepts every technician must understand about the Internet. First of all, the Internet is really just a bunch of private networks connected together using public telephone lines. These private networks are the access points to the Internet and are run by companies called Internet Service Providers (ISPs). They will sell you a connection to the Internet for a monthly service charge (kind of like your cable bill or phone bill). Your computer talks to the ISP using public phone lines, or even using new technologies such as cable or wireless.
