Different types of network cables are available market they are Coaxial cable, Optical fiber cable, Twisted pair cable. RJ-45 The most common UTP connector is RJ45 (RJ stands for registered Jack), as shown in Figure. The RJ45 is a keyed connector, meaning the connector, meaning the connector can be inserted in only one way. 2|Page Mahantesh Patil 2BV14IS410 CN LAB REPORT Dept. of ISE, BVBCET SWITCHES: Switches contain many ports to connect different network segments. They are similar to hubs, but offer greater performance. When a network contains a large number of devices, switches are needed instead of hubs to make sure the communications between devices does not slow down. Contrary to hubs, switches send the data it receives only to specific ports. NIC(NETWORK INTERFACE CARD) A network card, network adapter, or NIC is a piece...

...TCP/IP Protocol Suite Brad Kauble Benjamin Miller Networking 101 Section 104 November 20, 2013 In the world of the Internet and data networking, applications need a way to transfer information form one user to another, anywhere, anytime in a manner that does not disrupt the applications usefulness. Devices connected to a network use multiple applications simultaneously that send and receive information. That data cannot just be sent across the network with any hope of getting to its destination in any recognizable state if it were not for the Transport layer. The Transport layer divides the data into manageable pieces, packaging and addressing them so they will arrive at their proper destination and then reassembling the pieces into the original signal or stream. This paper will observe the part the Transport layer plays in application data encapsulating for use by the Network layer; how it allows simultaneous communication of multiple applications on a single host device while ensuring reliable data delivery to the right application correcting errors if required. The Transport layer is layer 4 in the Open Systems Interconnection (OSI) Model and layer 2 in the Transmission Control Protocol/Internet Protocol (TCP/IP) Model. The Transport layer is needed to track individual conversations, segment, manage and reassemble data packets, identify sending and receiving applications, perform flow control between end users, enable error recovery and initiate and terminate sessions...
