Internet connections in India have been wired starting with the dial up connection then the wired broadband connection. However off late wireless connections have been quite popular and have been accepted by the civil community. Wired internet connections have been the traditional choices in homes, but wireless technologies are gaining ground fast. Both wired and wireless networks have got some unique features which differentiate them from the other. Both also have certain advantages which the other lacks. But both wired and wireless connections can perform very well for home and other Local Area Connections (LANs).
Let’s see the features of wired connections
Wired LANs use Ethernet cables and network adapters. But two pc’s can be connected to each other with the help of an Ethernet Crossover Cable, wired LANs also need central devices like hubs, switches or routers to accommodate more computers. Earlier dial up connections would require the computer hosting modem to run an internet connection sharing or similar software to share the connection with all other computers on the LAN. Now Broadband routers allow easier sharing of cable modem or DSL internet connections, plus they often include built in firewall support.
Ethernet cables must be joined from one computer to another or to the central device. It is difficult and time consuming to join two computers through wires. Specially, when the computers are located in two different rooms. Where the wired needs to be run through walls, or under the floor. The exact configuration of cables depends on various factors like the mix of devices, the type of internet connection, and whether internal or external connections are used. After hardware installation, the remaining steps in configuration either wired or wireless LANs do not differ much. Both rely on standard Internet Protocol and network operating system configuration operations. Laptops and other portable devices often enjoy greater mobility in wireless home network installations.
Ethernet cables, hubs and switches are very inexpensive. Some connection sharing software packages, like ICS are free; some cost a nominal fees. 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.
Ethernet cables, hubs and switches are reliable and safe. Mainly because a lot of work has gone in improving in the Ethernet technology. 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.
Broadband 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.
Wired LANs offer superior performance. Fast Ethernet should be sufficient for home file sharing, gaming, and high-speed Internet access for many years into the future. Wired LANs utilizing hubs can suffer performance slowdown if computers heavily utilize the network simultaneously. Ethernet switches can be used instead of hubs to avoid this problem. It will cost a little more but will be effective enough.
Firewalls are the primary security consideration for any wired LAN connected to the internet. Wired Ethernet hubs and switches do not support firewalls. However, firewall software products can be installed on the computers themselves. Broadband routers offer equivalent firewall capability built into the device, configurable through its own software.
