What are the advantages and disadvantages of network processors, such as hubs, switches, routers, and gateways? Well the advantages of hubs are they allow nodes to connect to one another that will create a physically attached network and a less expensive than other network devices while being easy to setup. But being an easy-to-use device that broadcast to all ports can be really unsecured for many applications. Lastly the bandwidth is shared by all the PC’s connected to the hub which slows down the connection between all machines attached to it and can form bottlenecks. Next we have, switches that have many advantages. The greatest would be the ability to support multiple VLAN’s. Compared to a hub it is a smarter device and still easy …show more content…
The following summarizes the features of STP cable: • Speed and throughput—10 to 100 Mbps • Average cost per node—Moderately expensive • Media and connector size—Medium to large • Maximum cable length—100 m (short) cable consists of a hollow outer cylindrical conductor that surrounds a single inner wire made of two conducting elements. The following summarizes the features of coaxial cables: • Speed and throughput—10 to 100 Mbps • Average cost per node—Inexpensive • Media and connector size—Medium • Maximum cable length—500 m (medium) Fiber-optic cable used for networking consists of two fibers encased in separate sheaths. The following summarizes the features of fiber-optic cables: • Speed and throughput—More than 1 Gbps • Average cost per node—Expensive • Media and connector size—Small • Maximum cable length—More than 10 km for single mode; up to 2 km for multimode Wireless Networks use radio frequencies (RF) or infrared (IR) waves to transmit data between devices on a LAN. •Wireless frequencies range from 3 kilohertz (kHz) to 300 gigahertz (GHz). •The data-transmission rates range from 9 kilobits per second (kbps) to as high as 54 Mbps. • Media and connector size—Small • Maximum Transmission distance dependent on signal strength and antenna design. On average 30 ft. to 5 miles on average What is their performance in terms of reliability, speed capabilities, and nominal distance for reliable spans? All are reliable
The whole thing is usually wrapped in another layer of insulation and, finally, in an outer protective layer. (/coaxial_cable.html)
Wired network uses cables to connect devices to the internet, however, wireless network uses radio waves to devices to connect internet.
Eliminating Spark hazards: Fiber optic cables do not produce sparks since they do not carry current. Most electric potentials create small sparks which can be extremely dangerous in areas like chemical plants or oil refinery where air is contaminated with potentially explosive
For this cable I will use the Rj45 connector which is standard connection for most systems .I would then measure the cable I needed and trimmed it to the proper length using the cable cutter. Then I Used the cable stripper to strip about 1 ½ inch of the jacket from the end of the cable. Pull the trimmed jacket from the cable, there will be an exposed white thread cut that to the end of the strip cable so it will not be in the way of your connector. Untwist all the inner
12. Category 5e/6 Cable : cabling is used as a cabling infrastructure for 10BASE-T (Ethernet), full duplex 100BASE-TX (Fast Ethernet) and 1000BASE-T (Gigabit Ethernet, or GbE) networks. The Cat 5e standard provides performance of up to 100 MHz and can be used up to a maximum length of 100 meters.
* f times c = λ (where c is the speed of light: 3 x 108 meters / second)
A computer's wireless adapter translates data into a radio signal and transmits it using an antenna. A wireless router receives the signal and decodes it. The router sends the information to the Internet using a physical, wired Ethernet connection. The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer's wireless adapter (Brain & Wilson, 2011).
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
Basically, routers costlier than switches. VLANs is cost-effective than creating a new routed network with routers
In practice, there are some devices on market do not reach devices may reach up to several meter. The normal spot for IrDA communications is from 5cm to 60cm away from transceiver
A wireless network is any type of computer network that uses wireless data connections for connecting network nodes .Wireless networking is a method by which homes, telecommunications networks and enterprise (business).Installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure.
adopted for the Rion-Antirion bridge is further described in details to highlight how capacity design
Coaxial cable are classified according to it impedance. The one used in this exercise will use the impedance of 70 ohms with RG-58. This can be used for the discussed high speed internet requirements discussed above.
The cost for each wireless node is generally higher than a conventional LAN node. LAN devices Today, LANs use sophisticated programs that permit several users to work with the same resources at the same time. This can include hard disk drives, printers, plotters, software, etc. LANs are composed of various components performing specific tasks so each user can access shared resources.
up to 8 meters with the interference from the normal indoor lighting devices and provide a date rate of around 48 Mbps within 8MHz bandwidth.
