About Wired LANs\n\nWired LANs use Ethernet cables and network adapters. Although two computers can be directly wired to each other using an Ethernet crossover cable, wired LANs generally also require central devices like hubs, switches, or routers to accommodate more computers. \nFor dial-up connections to the Internet, the computer hosting the modem must run Internet Connection Sharing or similar software to share the connection with all other computers on the LAN. Broadband routers allow easier sharing of cable modem or DSL Internet connections, plus they often include built-in firewall support. \n\nInstallation\nEthernet cables must be run from each computer to another computer or to the central device. It can be time-consuming and difficult to run cables under the floor or through walls, especially when computers sit in different rooms. Some newer homes are pre-wired with CAT5 cable, greatly simplifying the cabling process and minimizing unsightly cable runs. \nThe correct cabling configuration for a wired LAN varies depending on the mix of devices, the type of Internet connection, and whether internal or external modems are used. However, none of these options pose any more difficulty than, for example, wiring a home theater system. \n\nAfter hardware installation, the remaining steps in configuring either wired or wireless LANs do not differ much. Both rely on standard Internet Protocol and network operating system configuration options. Laptops and other portable devices often enjoy greater mobility in wireless home network installations (at least for as long as their batteries allow). \n\nCost\nEthernet cables, hubs and switches are very inexpensive. Some connection sharing software packages, like ICS, are free; some cost a nominal fee. Broadband routers cost more, but these are optional components of a wired LAN, and their higher cost is offset by the benefit of easier installation and built-in security features. \nReliability\nEthernet cables, hubs and switches are extremely reliable, mainly because manufacturers have been continually improving Ethernet technology over several decades. Loose cables likely remain the single most common and annoying source of failure in a wired network. When installing a wired LAN or moving any of the components later, be sure to carefully check the cable connections. \nBroadband routers have also suffered from some reliability problems in the past. Unlike other Ethernet gear, these products are relatively new, multi-function devices. Broadband routers have matured over the past several years and their reliability has improved greatly. \n\nPerformance\nWired LANs offer superior performance. Traditional Ethernet connections offer only 10 Mbps bandwidth, but 100 Mbps Fast Ethernet technology costs little more and is readily available. Although 100 Mbps represents a theoretical maximum performance never really achieved in practice, Fast Ethernet should be sufficient for home file sharing, gaming, and high-speed Internet access for many years into the future. \nWired LANs utilizing hubs can suffer performance slowdown if computers heavily utilize the network simultaneously. Use Ethernet switches instead of hubs to avoid this problem; a switch costs little more than a hub. \n\nSecurity\nFor any wired LAN connected to the Internet, firewalls are the primary security consideration. Wired Ethernet hubs and switches do not support firewalls. However, firewall software products like ZoneAlarm can be installed on the computers themselves. Broadband routers offer equivalent firewall capability built into the device, configurable through its own software.\n\nAbout Wireless LANs\nPopular WLAN technologies all follow one of the three main Wi-Fi communication standards. The benefits of wireless networking depend on the standard employed: \n802.11b was the first standard to be widely used in WLANs. \nThe 802.11a standard is faster but more expensive than 802.11b; 802.11a is more commonly found in busi

Wireless devices will be everywhere. The phone, camera, and computer will merge with the internet. Vast databases of information will store, calculate, and notate every change everywhere. We will lose more privacy because of satellite imaging and web cameras. I know communications will become "one touch" access. The way we communicate will make the biggest changes. Look at what engineers have accomplished so far. Electronics is communication.

The Internet is the worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail , online chat , file transfer, and the interlinked Web pages and other documents of the World Wide Web .

Hello !\n\nThe difference between them is the frequency.\n\nCell phones use: 800, 900 or 1800 MHz or GHz[i hope I'm not wrong]\nand the\nWireless network uses: 2.4 GHZ and 5 GHZ spectrum.\n\n\n© ßogdan @ CyE CORP.

Cell phones, no matter what technology, use a paging channel with which they detect nearby cellsites and establish communication through control channels, which deliver synchronisation info. The control channel also establishes calls and manages the phone handovers to other cellsites.

You're probably thinking of TCP-IP and wikipedia has an interesting article on its history, and comparisons between the two. http://en.wikipedia.org/wiki/TCPIP  \n(It's far better than me boring you with explanations of models and standards)
