USB port can power up certain devices and transfer data at the same time. There are four cables inside the USB cable and two of them are used for power and two for data transfer. USB standards use A and B connectors to avoid confusion and relatively connectivity between computers through the USB cable does not provide fast speed. The speed also depends on the quality of the cable, operating systems, protocols, network devices, CPU and other electronic components.
Ethernet Straight & Crossover Cables
The most common method of connection between the LAN computer through an Ethernet cable. Ethernet is a local area network communication standard. The common types of Ethernet cables are straight cables, over cable and roll over cable. Straight cable is used to connect a computer with a hub or switch, cross cable is used to connect two computers directly without hub or switch or cross cable is used to connect two hubs or switches to each other. Roll over cable is used to connect the PC with the router console port.
Bluetooth Personal Area Network (PAN)
Bluetooth Personal Area Network is a technology that is used to create an Ethernet network wireless connectivity between mobile computer. In the Personal Area Network of up to eight computers, mobile devices such as mobile phones and PDA etc can be connected. A notebook with built-in Bluetooth radio can be connected with a desktop computer, which is equipped with an external Bluetooth dongle.
Wireless (Wi-Fi) ad-hoc network
Wireless network communication is possible through the IEEE Wireless 802.11b / g also known as Wi-Fi or wireless Ethernet. Computers with wireless LAN cards can send and receive communication signals to and from the access points. The core components used in wireless LAN are wireless routers, wireless LAN cards and access points, etc. For configuration the desktop computer plug the wireless access point on your computer and follow the instructions.
Fiber Optic Cable
A fiber optic cable is made up of strands of glass fibers, which enables transmission of data at the speed of light. Fiber optics have a large capacity and provide speed in GB. The signals through the fiber are transmitted without needing to be refreshed. They have a greater resistance to electromagnetic signals, near by cables, motors, and noise. Fiber to the home FTTH is becoming a common standard because it provides very high speed connections up to 100 Mbps and higher to the home users.
