Wireless is a technology that connects two devices to exchange data or voice without using a cable media.The advantages of technology is to eliminate the use of cables, which can be quite disturbing is aesthetically, and also the complexity of installation to connect more than 2 devices simultaneously. Wireless networks are popular for the construction of the home network, but wireless is not the only way, either wireless or wired home has advantages and disadvantages of each. There are 3 initial standard wireless network, which is used in 802.11b WLAN, 802.11a, and expensive faster than 802.11b and is usually owned by the business networks, and 802.11g is a combination of 802.11b and 802.11a, as well as the new 802.11n standard . While wired Ethernet cable and use the network adapter. In this network, to connect one computer to the computer interface is required of other cable networks, as well as hub, switch or router as the central device to handle many computers. Function in the network cable to send the information in the form of electrical signals between a computer network.
Here differences wired and wireless :
Installation
Wired, Ethernet cable must be on each computer to the computer or a central device. This often causes complications because of the length of cable required and necessary arrangements to wire the room neat. As for the configuration, wired or wireless networks are not much different. Wireless, can be configured in 2 ways namely ad hoc networks that can communicate peer-to-peer inter-device or with Infrasutructure the meperbolehkan mode wireless devices can communicate with a central point which then can communicate with wired LAN on the network. Most of Infrastructure mode wireless needs. Both need a Network adapter called WLAN cards.
Cost (Cost)
Wired. For the cost of Ethernet cables, hubs and switches is quite cheap. Software for connection sharing is also inexpensive and sometimes free. Users must prepare broadband routers (optional), although expensive, because of the ease of installation and safety. Wireless. Wireless is much more expensive than wired, including the price for its access point.
Reability
Wired. Ethernet cables, hubs and switches, broadband routers also sort can be very reliable because the updates are more mature than manufacturing. Physically, the connection cable can not be affected by interference or disturbance in the existing bandwidth, as in wireless networks. Wireless. Wireless LANs have less reliability than wired LAN, but can be covered if there is already good handling.
Performance
Wired. Wired LAN offers a very good performance. Ethernet was initially only able to offer 10Mbps bandwidth. Now that technology has to offer Fast Ethernet bandwidth of 100 Mbps, although some spend more money. Hub can decrease performance if the network is used continuously. However, this can be overcome by using a switch. Switches are more expensive than hubs, but the performance is better than the hub in order to prevent the decrease in network performance. Wireless. Wireless LAN with 802.11b provides the same speed as the Ethernet at the beginning of the presence of 10 Mbps. However, the wireless LAN 802.11a and 802.11g have 1.5 times the speed of Fast Ethernet. Drawback is distance sensitive wireless farther the computer user from the access point or other communication endpoint, it will decrease performansinya. 802.11a and 802.11g suitable for home networks, but not suitable for home LAN gaming.
Security
Wired. For any wired LAN connected to the Internet, firewall security is a primary consideration. Wired Ethernet hubs and switches do not support the firewall, but it can be installed. While broadband routers also provide firewall capabilities are easily configured with software software luggage. Wireless. Basically, wireless is less secure wired LAN because the signal is broadcast freely and easily captured. However, in practice such as wireless can be secure wired LAN, ie, by adding a password for wireless network settings that are not easily 'diintip' by the neighboring users, or by using data protection through encryption standards such as Wired Equivalent Privacy (WEP).
