When installing an area network one may have to decide whether they need a wireless network or choose from one of several cabling technologies. Though wireless networking takes off most of the burden involved in constructing wired area networks, its cons are watered down by the weakness of the signal on encountering obstacles. Installation of wide area networks includes cabling technologies such as the UTP (unshielded twisted pair) and STP (shielded twisted pair). These are terminated with the RJ 45 clips and are finally finished with the crimping tool. The other networking accessories used include routers, bridges, b-routers, gates and racks. These serve to transfer the datagram and enhance the signal strength once at the major network nodes. Network rack accessories hold the server processors in a cold room where the machines are supplied with UPS (unlimited power supplies) which take care of the networks power supply ensuring that sensitive data is not lost in case of abrupt power loss. Network rack accessories are meant to keep the server machines in good condition and out of any range of phenomena that might interfere with data being processed in these machines. Wireless networking though involves a few dedicated networking accessories including wireless adapters which enable remote computer operations without the need for network cable accessories. This includes the wireless network utility found in many airports and restaurants. Wireless technologies utilize the UMTS as well as WiMAX and GPRS. These are used for the provision of internet to mobile phones and devices like the laptops. The WiMAX and the UMTS technologies use networking accessories in a more innovative way. Thus the client now enjoys greater bandwidth in areas where the service was previously quite limited. This is made possible by a networking accessory otherwise known as the Wi-Fi card. This is an electronic board engineered to receive datagram sent to and transmit those sent from the device. The machines are initially installed with a networking interface card and given the basic TCP/IP configurations. This networking accessory provides a link between the terminal and the network enabling the user to make calls over the internet protocol.
