‘Chubby’ is a unified lock service created by Google to synchronize client activity with loosely coupled distributed systems. The principle objective of Chubby is to provide reliability and availability where as providing performance and storage capacity are considered to be optional goals. Before Chubby Google was using ad-hoc for elections, Chubby improved the availability of systems and reduced manual assistance at the time of failure. Chubby cells usually consist of chubby files, directories and servers, which are also known as replicas. These replicas to select the master use a consensus protocol.

4.11 Motor A DC motor is an electrical machine which converts electrical energy into mechanical energy. A magnetic field is generated by the current carrying conductor and when this system is placed in external magnetic field then the force is exerted which is proportional to the strength of the external magnetic field and to the current in the conductor, then motor will rotate. If the direction of current is reversed then the direction of rotation of motor will also reverse.
Bernadine Conklin Ms. Gross/Mrs. Abrams Quantitative project Section 3 20 October 2015 EAN-13 Check digits and codes are very important to the function and efficiency of a successful society. Whether it be the credit card codes or even looking at barcodes so an item is victoriously scanned. An important one that is used is the EAN Which stand for The European Article Numbering Code or even EAN-13 which is used for the identification of retail products. This contains both the 12 digit data of the product and the 1 check digit naming it a barcode of a numerical value of 13 .This was originally based off the old code of UPC-A (Universal Product Code), it then became the new standard of numbering codes.

First of all there are three of the same virus on the system that was scanned. That virus is called Win32/DH{eRUTxVzF3U} and it is one of the bad viruses that we do not want on our computers. The virus can replicate itself and attach and infect the files it attaches itself to. Once it starts to replicate itself that will take up space in your hard drive and make it so that you have less space for you to use. The virus can change the file that is in on or steal the information that inside that file, and it can send itself to other computers so that it will spread and continue replicating itself.

With widespread use of internet services, the network scale is expanding on daily basis and as the network scale increases so will the scale of security threats which can be applied to system connected to the network. Viruses and Intrusions are amongst most common threats that affects computer systems. Virus attacks can be controlled by proper antivirus installation and by keeping the antivirus up to date. Whereas any unauthorized access in the computer system by an intruder can be termed as Intrusion and controlled by IDS. Intruders can be grouped into two major categories which are external and internal Intruders.
1. List and explain the top 5 factors that are required, at a bare minimum, to make an application secure. Security architecture, authentication, session management, access control, and input validation are the top five factors that make an application secure. Security architecture: OWASP verification requirements in security architecture verify all the application components and libraries that are present in the application are identified. A high level architecture of an application must be designed.
1.8) Just as breathing and blinking involve a series of complex steps through complicated processes, our visual system has become effective and developed through evolution over millions of years. While the vision system may not be exactly performing this kind of mathematics, it has evolved in such a way that its design allows it to mimic this complex process. The gap between our visual systems abilities and our cognitive capabilities also helps free the conscious part of the mind, which allows animals to pay more attention to threats and be more likely to survive. 1.9) Evolution favors organisms that are able to live the longest and able to reproduce the most. Animals that acted irrationally were more likely to be killed and less likely to

Break Point 6.2 I think that the students are trying to describe what most people cannot: the effect that music has not on our minds, but our bodies. Because the mind is not involved in this physiological process, one can only begin to describe why we get "pumped," why our heart rates increase or why our moods change when we hear a certain piece of music. In the conversation in Chapter 6, each student seems to have a different way of describing how music makes them feel, which supports my belief that each student has a unique physiological approach when listening to or performing music that is unlike that of anyone else. As the chapter mentions, there is no true explanation as to why some people get goosebumps when a certain song plays and others do not. Personally, my musical tastes are all across the board, and change
