Unit 1 Exercise 1. IP Addressing Scenario

The subnet range would be one-hundred and forty five from one-hundred and forty six. The network number would be one-hundred and forty four. Also the broadcast number will be one-hundred and forty seven. In this case as far as which class it would be is class b. Honestly I would say because of the number of hosts.
In the case of the how the IP addressed would be assigned I would consider choosing statically. Why because a static IP address is a number that is assigned to a computer by an internet service provider to be its permanent address on the internet. Also an advantage of having statically IP addresses is that there easy to use and less expensive.
I would think that you should have multiple network or subnets just in case you want to expand the size of your IP addresses. If you keep everything at its minimum size or space then that’s all you have to work with. If you make sure that you have extra space, host or whatever it is that you need then you will be able to expand your idea and design.
The majority of systems we use can work well with DHCP so it shouldn’t be a problem. Although some system will need hosts files, also you should have many domain and DHCP servers.

In order for computers, printers, etc. to communicate with each other on a network, each must have a different IP address. To make remembering these easier, the Domain Name System (DNS) translates these numeric IP addresses into names and web addresses that humans can actually decipher and remember. Instead of remembering one of the five numeric IP addresses to find and DNS will go find the page you are looking for.
DNS is most commonly used for internet purposes, but private networks use DNS for other reasons as well. It works throughout multiple computers or databases. It can handle many types of name resolution requirements. With DNS the host name will stay the same even though the numerical IP address may be changing.
With all of the ways that DNS makes our lives easier in regards to networking, be that private networking or the internet, the overhead and IT management aspect of DNS are well worth it. I can’t imagine the headache of not having it in place.
DHCP (Dynamic Host Configuration Protocol) assigns IP addresses on a network. It provides the default gateway, subnet mask, and the DNS. It helps automatically assign IP addresses to any device. It reuses any IP address that has not been used so that no IP address goes to waste.

Unit 2. Assignment 1. DHCP Troubleshooting

Dear Junior Admin, My first question would be what have you done to this point about the issue? What OS are the computers running that have not picked up the new DHCP scope? Start by checking the DHCP setting and configurations are they all correctly configured? Try renewing the IP addresses on the workstations that have not picked up the scope it maybe do to the IP lease agreement. The Lease period defined for your DHCP, I think 8 days for wire and 24 for wireless. So machines will not request a new IP address until this lease expires.
If a Machine reboots it will ask for a new IP address from the DHCP, so I think the few machines that received new IP addresses from the new scope were rebooted. You should also check the system event log and DHCP server audit log files for details on any problems. Make sure the address scope has enough addresses if not widen the scope range. Check to see if it is a router problem and makes sure you have the service enable. If the OS is Windows XP, there is a

utilization of any fixed infrastructures or centralized access points. In MANET, every node acts not only as a host however also as a router to forward messages for different nodes that don't seem to be among the same direct wireless transmission range[1]. every device in a very MANET is free to move independently in any direction, and can thus modification its links to different devices frequently.

Distributed systems will help us to finish jobs faster by using multiple machines as one machine. This will be done using job scheduling and load balancing between multiple servers or machines. The machine, which request the jobs may, may divide it to multiple chinks, which the load balancer will send every chink to a server to be calculated then send response to the client. Other times, these servers could be used to serve multiple request from multiple users. In the case, the load balancer will…

Answer 1 - Prior to recording the video data, to calculate the scaling factor researchers need to place two markers at least one meter apart. Then they know the real length of the points and the projected length and can calculate the conversion factor. The image obtained after recording is small then real life person, so to convert it to real life scale we need scaling factor.

correctly. It is difficult to identify problems in heart, just by monitoring the heart rhythm for an hour or two when the patient is in the clinic. In order to achieve this, holter monitors are used to record the ECG data for long duration, i.e. 24 hours. 1. The first approach is iterative, i.e. the threshold for the next peak detection was calculated as a percentage of the previously detected peak. 2. The second approach involved the calculation of threshold based on the mean of a number of peaks detected…
