Unit 5 Assignment 1

According to (Burke, 2004),A switch is a multiport bridge. When a switch receives a frame (A data packet with address and other protocol information embedded), it amplifies the signal, looks at the MAC address to determine which port should retransmit the frame to get it to the intended network device and sends it to that port. The switch can be configured to disconnect any attached device, to discard frames intended for an attached device, to send frames with a specific hardware address to another hardware address instead and to copy a frame to a mirror port which can send it to an attached traffic monitor.

Ethernet is typically the technology that is used to allow computers locally to communicate with one another. Computers that are close to each other they are connected by Ethernet.

Legacy Ethernet is half-duplex, meaning information can move in only one direction at a time. In a totally switched network, nodes only communicate with the switch and never directly with each other. Switched networks also employ either twisted pair or fiber optic cabling, both of which use separate conductors for sending and receiving data. In this type of environment, Ethernet stations can forgo the collision detection process and transmit at will, since they are the only potential devices that can access the medium. This allows end stations to transmit to the switch at the same time that the switch transmits to them, achieving a collision-free environment. (Pidgeon, 2011)

LANs standards and protocols are Ethernet, IEEE 802.2 [IEEE 802.3, 100BaseT, Token Ring/IEEE 802.5 and FDDI.

Bus – All computers and devices are connected asynchronous to one linear cable known as a trunk or generally known as a backbone. each ends of the trunk should be terminated to prevent the signal from bouncing duplicate the cable. as a result of the network

In this type of communications two frequencies are used therefore the up and down links job is to separate such frequencies and eliminate interference in order to make full duplex communications possible. Usually the frequency carried by the downlink is lower compared to the uplink and the

17. __________ is a technology that allows computers to share a network or internet connection wirelessly without the need to connect to a commercial network.

The definition of a switch or network switch is a small device that joins multiple computers together, working on layer two of the OSI, to form a local

In that case, configure the port vale other than auto. For manual configure port seed is set to 10 or 100 Mbps the switch allows to configure the duplex mode. We cannot change the duplex mode of auto-negotiation ports. If it is a set the port speed varies to trigger on to auto on a 10 or 100 Mbps Ethernet port.

Metro Ethernet can connect business local area networks (LANs) and individual end users to a wide area network (WAN) or to the Internet. Corporations, academic institutions and government agencies in large cities can use Metro Ethernet to connect branch campuses or offices to an intranet. A typical Metro Ethernet system has a star network or mesh network topology with individual routers or servers interconnected through cable or fiber optic media.

Local area network (LAN) is a wireless network that is mostly used in a work place or small building. To be able to make this work, you will need an access point connected to a switch to create the wireless network. There are different types of hardware components that are used to set a wireless network up such as network adaptors, Ethernet cables and a hub.

A primary system is made up of at least two computing devices either wired or wireless points of connection; these points are “network ports.” There are usually one network hub or network switch that permits their interconnection. The most standard “wired” computer networks are known as “Ethernet.” This is made-up of UTP (unshielded twisted pair) cables, and just about all personal computers have a UTP Ethernet Network port as standard. The printer also comes with an Ethernet port, making it easily shared amongst the user of a network. Other wired channels are coaxial cable used for cable T.V, Category 6 cables used for LANs, and fiber optic cables used for high-capacity trunk lines. Most local area networks (LAN) are used in small businesses network. Wired networks are much more secure than wireless networks. The Computer Age has shifted from a traditional industry to an economy is formed on information computerization. The arrival of the computer age is associated with the Digital Revolution. Today, the internet has generated attritions from billions of people and industries worldwide it is now a global cultural

There were many networking terms used in this video. There were five that stood out to me:

“IEEE 802 subdivides the data link layer into sublayers, namely the logical link control (LLC) and media access control (MAC) layers, which provide protocol multiplexing and a multi-access mechanism, respectively. IEEE 802 is comprised of standards with separate working groups that regulate different communication networks, including IEEE 802.1, 802.3, 802.11 and 802.15.” (Technopedia, 2014).

A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.
