Some of the benefits of amplitude modulation are that it is simple to implement, it takes few components to demodulate it while using a circuit, and receivers are cheap to purchase and to use. The receivers do not need any specialized components to operate. There are some disadvantages of using amplitude modulation as well. They consist of higher power usage, often considered very inefficient. The bandwidth needed to transmit is double for the highest audio frequency.
NT1310 Physical Networking Unit 3 Assignment 1 Network Topology Paper * Ring Topology is a network setup that the devices are connected in a ring they can pass information back and forth to each other according to their ring structure. A Ring topology is highly useful and handles more loads better than the bus topology. Ring topology can also be called an Active Topology because messages are passed to each device in the ring. Some Ring topologies setups work differently based on which devices are being linked together to form the network. One of the advantages of a ring topology is the installation and troubleshooting.
Hypothesis: I expected that the high-density Polethene would sustain more weight than the low density Polethene before braking for many reasons. Firstly, the high-density Polythene has many more monomers in the same area of plastic surface. The denser plastic the longer it will stretch before breaking. The Low-density Polethene has fewer monomers than the high density plastic and therefore has fewer bonds that can move more easily and can be stretched more freely. Another reason I believe that the low-density Polythene will break first is because the monomers are in straight lines and the high-density polymers overlap giving the material more strength.
Ethernet or Token Ring IT 242 Nov 15, 2012 Ethernet or Token Ring For the first scenario of this assignment, I believe that Saguaro Federal should use Ethernet because it is safe and more secure. The reason Ethernet is more secure, is that it deals with the MAC layer of the OSI model. The token ring on the other hand would not be the best choice because everything connects within a star topology type of network connected with hubs. This can cause some problems in the future if one of the components requires maintenance or if it malfunctions. In which this can lead to downtime for the business and its users.
Analog and Digital Comparison NTC/362 Analog and Digital Comparison Rapid advances in telecommunication allow people to transmit and receive messages through signals of no physical substance. Presently, analog and digital applications work in harmony with one another through conversions in telecommunication. An analog signal is harder to reproduce than a digital signal, but both signals degrade over distances. Through the use of signal regenerators weakened digital signals regenerate and pass through the network. Analog signals send out video, voice, data, or image information.
The Class B network ID, will utilize the first two octets for the network ID, which allows more network IDs and fewer hosts than a Class A network, because it uses an additional octet for the network. Class C addresses are for small networks with few hosts. These addresses have the first three high-order bits set to 110, because Class C addresses use the first three octets for the network ID and the last octet for the host ID, used for individual IP multicast
Because the signal is concentrated in a narrower, focused area, the signal is stronger and therefore will carry farther than the signal from an AP using an omnidirectional antenna. 4. What are the two ways in which omnidirectional antennas differ from a directional antenna? Omnidirectional antennas transmit in all directions, both horizontally and vertically. The signal goes in all directions, as well as up and down, although there is often a small dead spot with no signal that is a very small area directly above
Switching over to Ethernet cabling would also be less expensive and more flexible than the existing coaxial cables and they offer more noise resistance. I can run the cables in the ceiling or between the computers so that they do not get stepped on or rolled over by the chairs. I will also need to put in a router or a hub to connect the client
Three methods were discussed and proposed for the experiment. The use of acyl chloride is a method and also the use of acetic anhydride. The method used in this experiment is known as Fischer Esterification. The before methods are much more expensive which is way it is shunned away in organic chemistry unless the reagents need to be used for other reasons beyond the scope of this paper. The Fischer esterification works just as fine and is cheaper so why not.
