IntroductionBefore describing the various connecting devices that exist in the networks, first I have to explain the TCP / IP is used by Internet.TCP / IP are two protocols (TCP and IP) is a set of protocols covering the different levels of the OSI model (Open Systems Interconnection). TCP (Transmission Control Protocol), is translated Protocol Transmission Control Protocol and IP (Internet Protocol), translated means Internet Protocol. The TCP protocol is responsible for managing the data and check for errors in transmission. The IP protocol is responsible for transporting data packets from one place to another. TCP / IP is compatible with any operating system and any hardware and is the most widely adopted architecture for the interconnection of systems. Contrary to what happens with OSI (open systems interconnection), the TCP / IP software, that is, a model to be implemented in any type of network. Facilitates the exchange of information regardless of the technology and type of cross subnets, providing seamless communication across heterogeneous systems. The TCP / IP and OSI is divided into levels, and is trying to pass information to adjacent levels. The number of levels varies according to the network. Each level n of a machine communicates with other machines at no peer calling process. To establish a communication each level, starting with the highest, sends information to the adjoining lower level to the level lower than directly accessing the physical media. On the target machine information shall remain the way up until you reach the next level. To normalize the levels structured networks in the International Organization for Standardization (ISO) proposed the OSI Reference Model (Open Systems Interconnection). The OSI system has 7 levels which are: Physical, Link, Network, Transport, Session, Presentation and Application. Each of these levels is done by a piece of hardware and / or system software. (Layer 1) Physical Layer: It is virtually all hardware and defines the medium (type of cable and connectors). (Layer 2) Link Layer: This refers to the connection between adjacent machines. Must ensure error-free transmission, for it divides the data issued in frames. Layer 3) Level Red: Responsible for routing packets from their origin to their destination. (Layer 4) Level of Transportation: Make an end to end connection between the transport layer of the source and destination machines. (Layer 5) Level of Session: Manage the control of dialogue between users of different machines to improve services between them. (Layer 6) Level of Presentation: It deals with issues of representation of information. (Layer 7) Application Level: It deals with terminal emulation, file transfer, email and other applications. Wired Networking DevicesNow talking about the Switches, routers, hubs, network cards and other network equipment and contact the distinction are two network cards and router hardware. NIC is a network terminal and network interface devices; and the router is used to guide the network information transmission. Hub is actually a multi-port repeater. Hubs such as the number of generally 4, 8,16,24,32 RJ45 interface, these ...
