10Example of networking cables and their functions, post at least 10 w/ picture.
1.)Serial ATA is the next -generation internal/external storage interconnect, designed to replace parallel ATA technology. Serial ATA is the proactive evolution of the ATA interface from a parallel bus to a serial bus architecture. This architecture overcomes the electrical constraints that are increasing the difficulty of continued speed enhancements for the classic parallel ATA bus. Serial ATA will be introduced at 150Mbytes/sec, with a roadmap already planned to 600Mbytes/sec, supporting up to 10 years of storage evolution based on historical trends. SATA/ESATA High Performance External Shielded Cables




2.)The cable networks are the most common and the most secure type of networking style. They have succeded in having very high data rates ranging from 10mbps to 100gbps as from 2007. The hardware has fast been evolving in the cable network arriving at a stable level while rising to higher heights.





3.)This definition closely duplicates the definition for twisted pair.)Shielded twisted pair is a special kind of copper telephone wiring used in some business installations. An outer covering or shield is added to the ordinary twisted pair telephone wires; the shield functions as a ground.Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. … Definition continues below.

4.)UTP cable (category 5) is one of the most popular LAN cables. This cable consists of 4 twisted pairs of metal wires (that means there are 8 wires in the cable). Adding RJ45 connectors at both ends of the UTP cable, it comes a LAN cable they usually use.





5.) USB adapter these days is one that connects an iPod or other MP3 player to its power charge





6.)HDMI is an uncompressed, all-digital signal, while the aforementioned interfaces are all analog. With an analog interface, a clean digital source is translated into less precise analog, sent to the television, then converted back to a digital signal to display on screen. At each translation, the digital signal loses integrity, resulting in some distortion of picture quality. HDMI preserves the source signal, eliminating analog conversion to deliver the sharpest, richest picture possible.




7.)Ethernet cable You can find bulk supplies of the cable at many computer stores or most electrical or home centers. You want UTP (Unshielded Twisted Pair) cable of at least Category 5. Cat 5 is required for basic 10/100 functionality, you will want Cat 5e for gigabit (1000BaseT) operation and Cat 6 or higher gives you a measure of future proofing. Bulk cable comes in many types, there are 2 basic categories, solid and braided cable. Braided cable tends to work better in patch applications for desktop use. It is more flexible and resilient than solid cable and easier to work with, but really meant for shorter lengths. Solid cable is meant for longer runs in a fixed position. Plenum rated cable must be used whenever the cable travels through an air circulation space. For example, above a false ceiling or below a raised floor. It may be difficult or impossible to tell from the package what type of cable it is, so peal out an end and investigate.





8.)Timbercon Introduces Light ARMOR Fiber Optic Cables; Durable, Protected, Lightweight Fiber Connections for Ruggedized Fiber Requirements.





9.)Crystek has introduced a new line of low-loss RF coaxial cable assemblies featuring rugged stainless-steel solder-clamp construction and attenuation of 0.36 dB/ft. at 18 GHz. The LL142 Series cable offers shielding effectiveness of greater than -110 dB with an operating temperature range of -55° to +85°C (extended range of -55° to +125°C available through special order).





10.)Broadband & MSO fiber optics: support broadband and MSO network applications from inside the central office all the way to the subscriber.

1.)Gateway: device sitting at a network node for interfacing with another network that uses different protocols






2)router is a networking device that forwards packets between networks using information in protocol headers and forwarding tables to determine the best next router for each packet. Routers work at the Network Layer (layer 3) of the OSI model and the Internet Layer of TCP/IP.




3.)hub contains multiple ports. When a packet arrives at one port, it is copied unmodified to all ports of the hub for transmission. The destination address in the frame is not changed to a broadcast address.





4.)Switches
A network switch is a device that forwards and filters OSI layer 2 datagrams (chunk of data communication) between ports (connected cables) based on the MAC addresses in the packets.[8] This is distinct from a hub in that it only forwards the frames to the ports involved in the communication rather than all ports connected. A switch breaks the collision domain but represents itself a broadcast domain. Switches make forwarding decisions of frames on the basis of MAC addresses. A switch normally has numerous ports, facilitating a star topology for devices, and cascading additional switches.[9] Some switches are capable of routing based on Layer 3 addressing or additional logical levels; these are called multi-layer switches. The term switch is used loosely in marketing to encompass devices including routers and bridges, as well as devices that may distribute traffic on load or by application content (e.g., a Web URL identifier).




5.)Remote bridges: Can be used to create a wide area network (WAN) link between LANs. Remote bridges, where the connecting link is slower than the end networks, largely have been replaced with routers.








6.)Wireless bridges: Can be used to join LANs or connect remote stations to LANs







7.)Repeater is an electronic device that receives a signal, clean it from the unnecessary noise, regenerate it and retransmits it at a higher power level, or to the other side of an obstruction, so that the signal can cover longer distances without degradation. In most twisted pair Ethernet configurations, repeaters are required for cable which runs longer than 100 meters.





8.)Data Link Layer is Layer 2 of the seven-layer OSI model of computer networking. It corresponds to or is part of the link layer of the TCP/IP reference model.





9.)Point-to-Point Protocol (PPP), HDLC and ADCCP for point-to-point (dual-node) connection





10.)Open Data-Link Interface (ODI), developed by Apple and Novell, serves the same function as Microsoft and 3COM's Network Driver Interface Specification (NDIS). Originally, ODI was written for NetWare and Macintosh environments. Like NDIS, ODI provides rules that establish a vendor-neutral interface between the protocol stack and the adapter driver. It resides in Layer 2, the Data Link layer, of the OSI model. This interface also enables one or more network drivers to support one or more protocol stacks.

1.)What is Network Topology?

topology refers to the layout of connected devices. This article introduces the standard topologies of networking.

6.)

The following examples will give you an idea of how to set up networks that have Ethernet, HomePNA and Wireless parts. They are intended to show some of the combinations possible and to highlight how many subnetworks are created when different products are used. These are just a few of the possible combinations. Let us know if there's a combo that you'd like to see.

3.)Open System Interconnection, an ISO standard for worldwide communications that defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, proceeding to the bottom layer, over the channel to the next station and back up the hierarchy.

2.)Exmple of TOPOLOGY

Think of a topology as a network's virtual shape or structure. This shape does not necessarily correspond to the actual physical layout of the devices on the network. For example, the computers on a home LAN may be arranged in a circle in a family room, but it would be highly unlikely to find a ring topology there.
