What do you think would be possible solutions? Include a drawing of the topology that should be used and what types of networks you propose would work here and the accompanying justification. The problem to this scenario could be a number of things‚ but we are trying to fix at a small cost and like I have always been told start

Distance Consideration 7.1.1 A WAN is a wide area network that is often used by large businesses or corporations. It is impractical for an organization to own an entirety of a WAN because a WAN is decentralized It’s l for an organization to own an entire LAN‚ or local area network‚ for business expansion purposes. This is control over a dedicated section of the local network that other businesses will want to buy into. 7.1.2 Increasing the required transmission distance of a signal will have a negative

IT/242 November 10‚ 2011 Philippe Rowland CheckPoint: Ethernet and Token Ring Network Saguaro Federal should use the Token Ring protocol for their banks and businesses. This is appropriate because the physical topology of the token ring is a star‚ but the logical topology is a ring. In Token Ring LAN’s each station is connected to a wiring concentrator called a multistation access unit (MAU) using UTP or STP. Like Ethernet hubs‚ MAUs are located in a wiring closet. The access method used

Data transmission‚ digital transmission‚ or digital communications is the physical transfer of data (a digital bit stream) over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires‚ optical fibres‚ wireless communication channels‚ and storage media. The data are represented as an electromagnetic signal‚ such as an electrical voltage‚ radiowave‚ microwave‚ or infrared signal. Data representation can be divided into two categories: Digital

freeing up network resources. From a security perspective‚ it allows us very granular control of the network.” (McIntire‚ 2001) The Plan In order to accommodate the changes the network needs due to expansion and relocation the Local Area Network (LAN) must be segmented into different broadcast domains through the use of the VLAN. Incorporating the VLAN will reduce the number of router hops and increase the apparent bandwidth for the user. Security To improve security‚ separating systems that
