CompStat gives officers specific details so that they know exactly where to direct their attention. Simply patrolling the streets allows officers to have more of a community presence and build relationships with citizens of the city. CompStat’s output is based on past crimes, so patrolling the streets would make officers more accessible to adrress crimes that are happening for the first time. Compstat takes control of the streets away from the patrol officers and places it in the hands of the

can only have dual cores. Multiple cores increase processing power and spread the workload which makes it easier to handle larger data sets. Physics researches would most likely prefer a computer which has a 64bit CPU because of the amount of data they will need to process, also some of the applications they may need for certain computations may have minimum requirement of 64bit due to the complexity and scale of the data sets they will be processing. In short, the more free RAM a computer has, the

This is not true because, for the most part, the CPU cannot keep data stored inside it like a human brain. It is used to process much of the information needed by the computer, just like our brain thinks and processes

organization –Six building blocks of computers: input, output, memory, arithmetic/logic unit, control unit and files. Control unit and arithmetic/logical unit together known as CPU (central processing unit). –Arithmetic/Logic Unit: carries out mathematical operations and logical comparisons, consist of very large scale integrated circuits, can perform billion operations per second, numbers taking from memories as input and results stored in memory as output. -Control Unit: controls the other five compo

and when they do, they are easily repaired. Consistent: if you input the same data into the computer using the same program, it will give you the same result all the time. Communicate: people can connect with others by the use of computers. Information Processing System DATA is a collection of independent and unorganized facts. INFORMATION is the processed and organized data presented in a meaningful form. DATA PROCESSING is the course of doing things in a sequence of steps. COMPUTER is
