CS320 Assignment 1 Andrew McConnon 13349871 You want to connect different computers, at different locations, so that they can exchange data with each other. What are the different challenges that you need to overcome? Host Identification on small networks isn’t a problem as it can be set up with manual ways of addressing, but will be exponentially harder the larger a network becomes. Protocols, DHCP servers and addressing are a huge need if you want to create and sustain a large, expanding…

Create new scope of server, Assign scope name and description. Now define a range of IP address, start and end date Now use any excusive address that is server IP address Now select lease duration, now configure DHCP [3] options now Insert router IP address which is 192.168.1.1 in my case, press next---> Next--->activate scope now--->then finish 5) Roaming Profile [4]: For creating of centrally profile [4] of all domain users’ roaming profile [4] is use. In…

1. Goal The primary goal of this lab was to establish a base network in RLES that will be built on in future labs. We worked with new PFSense, a routing interface with which I was unfamiliar. I learned how to configure internal and external interfaces with PFSense, and was able to modify the rest of the necessary settings via the Web GUI. We learned how to configure RHEL, and also got to experiment with setting up a Wiki. Finally, we had a chance to configure and work with a monitoring…

new devices in the entry level tier are the Roku Express and Express+. Roku has not only unleashed a deluge of streaming devices, but also some new functionality available in the Roku operating System. Furthermore, two of the devices support High Dynamic Range (HDR) video on HDR compatible TV 's. You can read about HDR video in this article,…

QUES 1. A router has the following CIDR entries in the routing table: Address/Mask Next Hop 135.46.56.0/22 Interface 0 135.46.60.0/22 Interface 1 192.53.40.0/23 Router 1 Default Router 2 For each of the following IP addresses, what does the router do if a packet with that address arrives? 1. 135.46.63.10 2. 135.46.57.14 3. 135.46.52.2 4. 192.53.40.7 5. 192.53.56.7 g entirely with bytes is much simpler than working with individual bits. Answers: 1. 135.46.63.10 Using the first 22 bits of it as…

recent years, much effort has been done to solve the problems of huge processing time associated to large amount of particles required for simulating practical problems with desired refinement. However, the efficient use of the currently available computational resources, such as computer cluster, remains as a challenge. One of the critical…

performance factors such as the flow coefficient and hydrodynamic flow coefficient were computed for different valve opening angles. The results demonstrated the importance of CFD as a valuable tool in visualizing the complex structures in the flow of fluid in the valve. The hydrodynamic torque coefficient curve was computed at different valve opening angles, and the angle at which maximum torque coefficient occurs was identified…

High temperature proton exchange membrane fuel cells (HT-PEMFCs) are a promising clean technology, especially for automobile applications.1 These devices generate electricity from the chemical reactions that occur in the anode side of the cell, using H2 as a fuel and generating heat and water as by-products.2, 3 However, experimental studies using HT-PEMFCs show that degradation of the cell can occur after certain hours of operation (around 500 hours).4 Some of the factors that contribute to the…

used to solve the governing equations in two distinct steps. In the first step, intermediate velocities are calculated, using the time splitting method for the solution of advection-diffusion, surface level gradient, bed roughness, sponge layer and dynamic pressure gradient terms. For each term, a proper solution method is applied. Leapfrog scheme is used to obtain a second order accuracy in time domain. To ensure local momentum conservativity and monotonicity of the solution, the momentum and…
