Cisco Network Topologies and LAN Design
Cisco network topologies and LAN network designs are vital internet platform for business activities as well as communication. In line with this, these network infrastructures makes the relaying of information from one source to another via the Internet easier for millions of individuals located in different parts of the universe. In analyzing these network infrastructures, the paper conducts a case study on growth and usage trends of Cisco's network topologies as well as LAN design in schools located within Baltimore, Maryland.
Network Usage Statistics
Since the inception of Cisco network, the number of the network design users worldwide has grown steadily over the years. At the beginning of the year 2000, there were less than 15 million Cisco network users across the globe (Odell, Korgen, Schumacher, & Delucchi, 2000). Moreover, widespread Internet usage has made the spread of the network design easier and made and the world smaller; a digitalized village. In the United States of America, the number of Cisco network and LAN subscribers has steadily risen to over two million subscribers in the present times. In addition, the use of Cisco network topologies has continued to serve a more diverse number of individuals and the table and graph below highlight the incredibly fast evolution of the topologies in America.

These aspects should be considered while designing and implementing a network to gain maximum efficiency. (Trulove, 19-20) The standard that defines the application of a WLAN is IEEE 802.11 WLAN standard. Though this is the basic standard amended ones define the additional prescriptions added to it like 802.11a or 802.11b. The capacity of a WLAN is defined by its basic compatibility. WLAN of the latest version comes with an 11
The diffused infrared configuration however, uses a transmitter that fills a given office space with signals. The signal receiver can then be located anywhere in the office area in order to successfully receive the IR signal. The Spread spectrum LANs This form of arrangement utilizes the multiple-cell configuration. Each of the cells are appropriately assigned a unique center frequency that lies within a specific band in order to avoid signal interference. This
So as to receive the infrared signals, the receivers can be placed at any location within the office space. The spread spectrum WLANs This system makes use of multiple-cell configuration. This is to say that each of the cells in the arrangement is assigned a certain center frequency that is unique and that lies within a chosen band as to eliminate chances of signal interference. The system employs frequency hopping and
Much work remains to enable a seamless Integration, for example that can extend IP to support mobile network devices. (Chlamtac, Conti, and Liu, 2003) 4G is stated to begin with the assumption "that future networks will be entirely packet-switched, using protocols evolved from those in use in today's Internet." (Chlamtac, Conti, and Liu, 2003) It is reported that a 4G wireless network that is all IP-based "has intrinsic advantages over its
FDDI's emergence as a networking interface standard is assured given its adoption across both Token Ring and TCP/IP-based networks and heterogeneous LANs that rely in large part on Fiber Optic cabling to ensure the highest level of performance possible. Summary Fiber optic cablings' unique set of advantages makes this specific type of connectivity solution ideal for high bandwidth requirements of LANs and WANs that transmit voice and data as the majority
Wireless LANs Replace Wired LANs? The convenience of wireless communication is so overwhelmingly obvious that given a choice, and provided there are no price constraints, almost everyone would prefer wireless instead of wired communication. This is reflected in the widespread use of devices such as remote control for TV, cellular telephones, pagers, and remote garage openers. The flexibility, mobility, and convenience that such 'wire-less' devices bring to our lives are
