...Running head: Computer Systems Architectures Computer Systems Architectures Kaplan University Abstract Computer architecture is a set of rules that say how software and hardware interact to create a network or platform. In other words computer architecture is the design of the network base on the needs of the user, the system if it is there or needs to be built, and the technology that needs to go into the project. System design is all how all the hardware is set up while the instruction set architecture is the program language. Table of Contents Introduction What OS file system should we use? What types of processors? Cluster Architecture? Data Backup LAN or WAN Web-based diagram Introduction to Coast to Coast computing We can get in a plane and be across the country in a few hours but what if we need to work together faster than a few hours? Is it possible? How hard is it to have users in California work with users in Washington, New York, and Florida? What has to be done to make this happen? How secure will it be to have such a network? This and many other questions come up when a company starts thinking of expansion beyond the building or city they headquartered at. When looking at a network a business wants to be sure it is using the most cost effective form for the network. The base of a network is the architecture. For small businesses a peer to peer architecture would be best. There are three types of peer-to-peer architecture: collaborative computing...

The only people who can open the file are the owner, user with the private key, and recovery agent. Once you go to the file right click then click the properties button. Once you click the properties button click the advanced button then select encrypt contents to secure data. Once you have done this the file name should turn a different color. * Public key- is used to encrypt * Private key- is used to decrypt 2. Windows firewall can block ports and IP addresses.

...This paper will discuss the environmental law Safe Drinking Water Act (SDWA). It will summarize its major provisions as well as describe the economic impact it has had. This paper will also include my opinion on whether or not science has proven that global warming is a credible threat. The Safe Drinking Water Act (SDWA) is the most comprehensive regulations for safe drinking water. (Editorial Board, 2013). This act was passed in 1974. Its main provision or goal is to ensure that all public water supplies and it sources such as rivers, lakes, reservoirs, springs, and ground water wells meet the national standards to protect individuals from harmful contaminants that can enter the safe drinking water system. The SDWA allows for the EPA to delegate the physical regulations of the public water system to the states such as size, capacity, etc. The provisions under the SDWA allow for proper monitoring of the water quality. Water sample are collected in intervals at a specific location, and then the samples are sent to a state approved testing laboratory. The results from the lab are then sent to the state to determine the public water system is in compliance with the Safe Drinking Water Act. SDWA requires reports to be made to the public if the water is in violation. SDWA has definitely had an impact on the economy. "The cost side of the analysis includes estimating the expenditures needed to comply new regulations to install contaminant removal technology and determining...

...Safeguarding children and young people. P3. There are four main times of abuse which are defined in the UK government guideline, these are; physical, emotional/psychological, sexual and neglect. Bullying is not actually said to be a form of abuse however it is still abusive and will be included in one of the categories of abuse. Most children will naturally get cuts and bruises from their day to day life, any injuries should always been seen in light of the children’s history. Their medical and social history should be looked at as well the child’s developmental stage and the explanation given. Most of the accidental bruises are found over the more bony parts of the child’s body for example; knees, shins, elbows and the front of the body. The key indicators of physical abuse are bruises and other injuries which are either unexplained or inconsistent with any explanations given, or the child may give a different explanation to their parent/guardian or whoever did it to them. Cuts, bruises or injuries which are visible on soft parts of the body where accidents are unlikely are also a key indicator example; cheeks, bum or abdomen. Other signs of physical abuse could be unexplained bruises or marking, multiple bruising, human bite marks, cigarette burns, broken bones, scalds with upward splash marks, multiple burns and shaking. Changes in the child’s behaviour can also indicate abuse. The child may become fearful of their parents being approached, they may get worried at events...

...Ayoub Elmahi NT1110 Research Paper IDentity Theft Ms. Janine Aleong Thursdays 9AM Research Project: IDentity Theft History Much before the internet technology had gained popularity, identity theft was common in form of dumpster diving and going through your trash in case you have thrown away any personal identifying information such as bills or documents. But before that, identity theft was known as a white collar crime and it was pretty dangerous. This means that if the id thieves wanted to steal your identity they would just kill you for it and just assume you identity and walk away. Back in those days the thieves also used phone scams to gather information about you. For example, the identity thief would just call someone and say they had won a huge prize and that they needed their personal information such as social security number and date of birth to verify their identity. This information was quite sufficient for them to commit crimes and leave you under debts. However with the rise of the internet technology, identity theft has become a more common crime and even easier and safe to perform without being caught. The quick growth of id theft History of identity theft had suddenly taken a sharp turn at about the time free exchange of personal and financial information become common by the use of computer and electronic devices. Identity theft is today considered to be one of the fastest growing crimes throughout the world. This rapid growth is mainly because of...

...Assess strategies and methods used to minimise the harm to children, young people and their families where abuse is confirmed (M3). Justify responses where child maltreatment or abuse id suspected or confirmed, referring to current legislation and policies (D2) Assess strategies and methods used to minimise the harm to children, young people and their families where abuse is confirmed (M3). Aside from removing children from their families in a confirmed abuse case, there are other ways to ensure that the child will be looked after correctly, as in some cases, it is not always the parents doing the abusing, it could be family members or even a stranger that has groomed them. One strategy would be parenting classes, which is also recommended by paediatricians in cases of neglect or maltreatment. In parenting classes, parents will be given the basic insight of how to cope with children during tantrums. This is main reason for why children are neglected. Mothers may suffer with post-natal depression, which may lead the to not be able to cope with their baby consistently crying, the same if they have older children also. It will teach parents to soothe their children during these episodes, and help them to understand that things like this are perfectly normal whilst their child is growing up. If their child has been a victim of sexual abuse, they may be referred to parenting classes to try to keep their child safe online, if it is grooming, or if it is done by someone that they...

...(P1) Outline why children and young people may need to be looked after away from their families. Looked After Children. The Children Acts of 1989 and 2004, has been introduced to keep children safe and be supported of anything that may harm the child in it’s home. Children and young people may be looked after through a legal agreement, such an imposition by the court. Where their guardian or parents would have to agree on the court orders. The reasons, this may take place is linked through family related complications, as the individuals maybe going through a bereavement or loss of a parent, or else the child’s guardian or parent maybe undergoing a treatment which insist of a serious illness they are going through or the parents/guardians are unable to take care of the child and not meeting their daily requirements. This may possibly be that the guardian or parents may have mental health issues, or they may be away from home and being treated in the hospital for a long period of time and this could lead the child of being looked after by secondary care, such as children care homes or foster parents. Another reason is that the parents maybe suspected of abusing their child. The length of the time they spend in this situation will vary according to the circumstances. Abuse can happen to children in various different ways, where the child might be taken away in to care by social worker and put them in a child’s home till the parents get help or the child’s custody maybe taken...

...Unit 10 Assignment 10: FCAPS is a network management framework created by the International Organization for Standardization (ISO) (Rouse, 2007). FCAPS categorizes the working objectives of network management into five levels. The five levels are: fault-management (F), the configuration level (C), the accounting level (A), the performance level (P) and the security level (S) (Rouse, 2007). The Marketing Company is a mid-size business that needs network management software. I recommend the Marketing Company should utilize network management toolset of the OpUtils software. It monitors network performance, calculates the bandwidth utilization, and scans the traffic for errors through SNMP. The tool also provides asset details such as the OS, installed software, and hardware and informs you about the general availability and performance of the network elements ("Network management tools," 2014). The goal of fault management is to recognize, isolate, correct and log faults that occur in the network. Furthermore, it uses trend analysis to predict errors so that the network is always available. This can be established by monitoring different things for abnormal behavior. When a fault or event occurs, a network component will often send a notification to the network operator using either a proprietary or open protocol such as SNMP (such as HP OpenView or Sun Solstice–formerly Net Manager), to collect information about network devices or at least write a message to its console for...

...Unit 10: Assignment 1. A company like Microsoft would have to back up everything on the server. Having a full backup is necessary for Microsoft because of the software and tools they provide for computers and for the financial department for payment plans. They would be required to have a full rotation of data. Microsoft would need roughly 15 data sets. They would be required to backup any search history, email history and file history; which will be dependent on the client. The data should be taken offsite on a daily basis. Sometimes, depending on the amount of data being backed up, the data should be taken twice a day for a company so big. If the current set in the server room were to be destroyed, a lot of data would lost (Too much to try and calculate). The most amount of time the server could be down could be at least 24 hours, maybe even longer. The most amount of data that could be saved by paper backup, would be roughly 2%, everything is done electronically now so 2% seems like a fair estimate. To fully restore a server from Microsoft, it could take a few days or a few weeks. Depending on if the company does a Data restore on a daily basis and how much they restore. To test any restore, you would perform a Data Recovery Restore on a daily basis to ensure that the backup restore is functioning properly. The backup media will be tested for corruption. The procedures for testing and verifying the backup media is the same. Do a data restore on a daily...

...Timothy Knox 8/21/2015 Dr. North Unit 10 10.1.1 TCP can connect two hosts with the capability to retransmit dropped packets, maintain ordering, and check for errors. A TCP connection is established with a three-way handshake in which a connection is established and acknowledged. What are the three messages that form this handshake sequence? Why is this important for establishing the connection? Use your textbook and Internet research to compose your answer. The messages that are used to form the handshake are SYN, SYN-ACK, and ACK. They are important because it allows for both ends to initiate and communicate using different TCP sockets at once. 10.1.2 By establishing a TCP connection, you allow one host to verify expected communication to and from the connected host. This provides two important features: windowing/sequencing and error checking/recovery. Windowing and sequencing are used to determine whether messages have been seen and are delivered in the correct order to the recipient. Error checking makes sure that all the packets are delivered as expected, providing reliability. Why are reliability and sequencing important in message delivery? Give an example of when each would be necessary. Its important because it allows for the organization of multiple messages so that the right message is sent in its proper order. Sequencing is the other important part because it makes sure things are in order and also that they are received in the right time frame and...
