The internet is a large worldwide collection of networks that use a common protocol to communicate with each other. While being in my house and not near my desktop computer which contains a desktop monitor and a modem I use my smartphone to access websites. My smartphone does not hook up to a physical network it deals with transmission media which deals with a wireless server. From my smartphone‚ I have access to several web browser applications‚ including Google‚ Bing‚ and Yahoo. At my house‚ we

: Questions Question 7: How do local area networks (LANs) differ from metropolitan area networks (MANs)‚ wide area networks (WANs)‚ and backbone networks (BNs)? One of the key differences between different network types is their geographical scope. A local area network‚ or LAN‚ is made up of a smaller group of computers linked together and located in the same small area such as a room‚ a floor or a building. A backbone network‚ or BN‚ is a larger network which connects multiple LANs‚ WANs

How VLAN’s work Types of VLAN’s Types of Connections Conclusion Reference links Introduction A Local Area Network (LAN) was originally defined as a network of computers located within the same area. Today‚ Local Area Networks are defined as a single broadcast domain. This means that if a user broadcasts information on his/her LAN‚ the broadcast will be received by every other user on the LAN. Broadcasts are

Switch: Communication networks may be categorized by the architecture and techniques they use to transfer data. The following types of networks are in common. Broadcast communication networks. Local area networks. Packet radio networks. Satellite networks. In broadcast communication networks‚ there are no intermediate switching

Part 3 Local Area Networks (LANs) connect multiple computers that in a geographically limited area‚ this can be within the same room or building‚ to share information and resources. A LAN enables devices to communicate over a network with one another internally‚ otherwise known as an intranet. Each Kudler location would represent a LAN since each location has an internal network that is sharing local resources. The majority of LANs are connected using cables with copper or optics‚ but a network setup

that can connect 2 local area networks (LAN). A bridge can learn all of the MAC addresses on the network‚ and this is done during the bridges data gathering phase. Basically a bridge will receive the data and analyze the address. The bridge will then pass the data on to the correct address. The ports on a bridge are in and out‚ but they are smart ports with the ability to locate the address on the network. Switches are much like a bridge where they can connect networks that use the same
