CNT5106C Computer Networks‚ Summer 2010 Instructor: Prof. Ahmed Helmy Homework #1 On the Internet Architecture‚ Elementary Queuing Theory and Application Layer I. Internet and layered protocol architecture: Q1. (5 points) In the layered protocol architecture the transport layer functionality includes congestion control and error recovery (e.g.‚ retransmission). One suggested that this functionality should be done strictly at the end points (i.e.‚ at the hosts) without aid from the network. Do you

1. Frequency Division Multiplexing Frequency Division Multiplexing is a technique that can be applied when bandwidth of the link is greater than combined bandwidth of signals to be transmitted. Frequency Division Multiplexing technique is the process of translating the frequency of individual channel into per-assigned frequency slots within the bandwidth of the transmission medium. Different carries frequencies are assigned to different users. We can use any modulation scheme to assign carrier

I am proposing to write about becoming a network and computer systems administrator‚ one of the reasons I chose this field to do my final project on is I am already in this field of work and feel that I have a fairly good background and plenty of information to share with others. I started in the Information Technology field in 2000 as a System Support Specialist for a fairly good sized Insurance Company. I have always like computer and figuring out what makes them work so when I had the chance

3.1.3 Computer Network Topologies Network Topology is a network specification that determines the network arrangement‚ connecting the senders and receivers through lines of connection. Topologies are of both physical and logical aspect of the network. The physical topology describes the network’s physical wiring layout or shape. The logical topology describes the path through which the data moves. Both logical and physical topologies could be same or different in a same network. The physical and

Security 4th Edition Questions Chapter 6 Questions 1. What is the typical relationship among the untrusted network‚ the firewall‚ and the trusted network? The relationship is that data is only limited to what firewalls allow via specific places called “ports”. There is the untrusted network on the outside‚ then the firewall which prevents unwanted or suspicious connections‚ and the trusted network is what lies within the bounds of the firewall. 2. What is the relationship between a TCP and UDP packet
