7. What is the piece of hardware that allows a device to physically access a network?

• “IP (the Internet Protocol) is the most common Network Layer protocol where routing occurs” (Network Design, 2012). I will put in place two wireless network interfaces, which will interconnect with the newly installed fiber optic routing system. Internet nodes will communicate via the IP address, 172.15.100.10.

System extension used to make an association between two different PC systems or to gap one system into two. LAN switch-gives a focal association between two or more PCs on a system.

A LAN is a ‘Local Area Network’. It is a small network of computers most often

It is in most cases used to connect multiple local area networks together to form a bigger network.

Wireless Routers is a wireless local area network (WLAN) that determine the next route of the packet should travel to the destination (Rouse, 2005). It converts the internet connection that was received from phone lines into radio signals and brings convenience to the portability devices that has built-in network card to gain the radio signals to get to the Internet connection (Switcher, 2015). Table 2 refers to the comparison of three models of wireless router.

Router is a device for networking that sends packets of data between the networks of a computer. The packet of data is forwarded to routers of the networks that contain the internetwork until the packet is at the destination node. A router can be linked to several data lines from various systems. The router reads the address information in the packet to establish the ultimate destination when the data packet is in any data lines (Liu, 2012).

every other node that receives them from the neighbors of S, until they arrive at the destination. When reactive routing protocols such as DSR or

A LAN networks job is to link computers together through a central device. That central device is the router, it is what transfers data to and from computers with an Ethernet cable or wirelessly as long as you are connected to the network. When you connect to the internet you are actually connecting to millions of networks that are connect through a multitude of ways: telephone lines, cable, and even fiber optic lines. A LAN and the Internet are the same only in the way that they both need a router to, well, route traffic. You actually can incorporate the Internet access into a LAN. The modem must be connected to the router and then that will provide a gateway between the Internet and the network connection. A firewall is very important

23. The process used by a router to accept a packet on one interface and forward it out another interface.

Packets also known as frames are grouped amounts of data that are sent across a network. However, packets differ from frames in that a packet contains that data to be sent, including the source and destination Internet Protocol (IP) addresses. A frame is packet that contains the data, the source and destination IP addresses, Media Access Control (MAC) source and destination addresses, and error checking. The MAC addresses are added at the beginning of the data also known as a header. An error checking code is also added to the end of the data which is referred to as a trailer. After the packet has been “framed”, the frame is then sent over the networking medium (i.e. Ethernet cable).

Most business networks today use switches to connect computers, printers and servers within a building or campus. A switch serves as a controller, enabling networked devices to talk to each other efficiently. Routers, on the other hand, are a much more sophisticated piece of technology. They are small like a switch and look like modems in which multiple nodes can be connected. Today’s routers are actually designed for the purpose of connecting multiple ‘area networks’ (both local and wide). In terms of the internet, routers actually serve as a temporary destination for network traffic. Routers are capable of transmitting and receiving data packets but will actually ‘read’ the packet to get its IP address for determining the packet’s destination. Unlike the switch, routers are capable of joining the multiple networks together; in the case of Kudler Fine Foods, their three store locations. “Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size.” (FCITC, 1997) There are four basic types of cable: Unshielded Twisted Pair (UTP), Shielded Twisted Pair (STP), Coaxial Cable, and Fiber Optic Cable. Unshielded twisted pair can range from basic telephone-grade wiring to high-speed cabling. This cable consist of four pairs of wires inside the outer covering each pair twisted with a different number of twists per inch to reduce/eliminate interference from adjacent pair or other devices. The tighter the twisting the higher data rates it supports but it also will increase the cost of the cable. Shielded twisted pair cables are actually shielded from radio and electrical frequencies and

Determine the destination data-link address used for forwarding packets to the next router or destination host (as directed in the routing table).

A router is what devices connect to, to get access to a network, the router assigns a separate IP address to each device that is connected to it. A router would then connect to a modem to provide internet access to the devices connected to the router. The purpose of a router is to send and receive data packets. When a data packet comes in to the router, it reads the address from inside the packet to know where to send the packet too. The

While data transferred in a network, is sent or received(for simple understanding, an e-mail note or a Web page), the message is divided into little pieces called packets. Each of these packets includes both the sender 's internet address and also the receiver 's internet address. A packet is firstly sent to a gateway computer which is the first station of the Internet. The gateway computer reads the destination address and forwards the packet to an higher gateway which reads the destination address and transfer it over the internet until one gateway recognizes the packet as belonging to a computer within its area or domain. The packet then is sent by gateway directly to the computer which address is specified.
