Hello, I’d like someone to write a 25 page Course Work on a networking subject. Doesn’t matter on what. I am providing some example topics if needed: 1. Theoretical background for the data transmissions. Fourier analysis. Signals with limited bandwidth. Speeds of data transmissions of the main harmonics. Maximal speed of data transmission on noiseless channel. Maximal speed of data transmissions on noisy channel. 2. Communication trunks and multiplexing. FDM, TDM principles of multiplexing. Means of operation on FDM and WDM. Means of operation of TDM. Pulse Code Modulation (PCM), structure of the frame. Scalability schemes of multiplexing of channels ?1 and ?1. 3. Principles of multiplexing of Code Division Multiple Access (CDMA). Mean of operation, chip sequence. Examples for simultaneous operations of several stations. Peculiarities and advantages of CDMA. 4. Cable television. Distribution of the cable TV. Internet on wire. Distribution of the signal spectrum. Cable modems and it synchronization. Peculiarities of the operation of upstream and downstream channels. Comparison between ADSL and cable modems.. 5. Network hardware. Technologies for data transmissions, Point-to-point, broadcasting. Local area networks. Topologies. Metropolitan Area Networks. Wide area networks. Wireless networks. 6. Protocol reference model of OSI. Description of the layers and the functionalities per layer. Physical layer, Data link layer. Network layer. Transport layer. Session layer. Presentation layer. Application layer. Functionality of the OSI reference model. TCP/IP protocol. Comparisons between OSI reference model and TCP/IP protocol architecture. Terminology for the term packet for the different layers of the TCP/IP protocol stack. 7. Layer 1 of the TCP/IP protocol stack: Network Access Layer (NAL). Functions, performed on the layer. ??? address in Ethernet networks. Local Area Networks LAN. Ethernet networks. Historical developments. Ethernet principles. Types of networks, following the standard 802.3. Switching network devices: switch, router. 8. Layer 2 of the TCP/IP protocol stack: Internet layer.
