Abstract This paper will compare and contrast the application of information technology (IT) to optimize police departments’ performance to reduce crime versus random patrols of the streets. It will describe how COMSTAT as an information system (IS) implements the four (4) basic (IS) functions; and it will discuss the fashion is which IT systems have made police departments more efficient in preventing and responding to crime. We will also explore the strengths, weaknesses, and SWOT analysis.

There are two types of IT controls: IT general controls, which are controls over the IT environment, computer operations, access to programs and data, program development and program changes; and IT application controls, which refer to transaction processing controls (“Information Technology Controls”, 2013). IT General Controls are the foundation of a company’s IT control structure. With IT General Controls, data that is generated can be deemed more reliable and assertion that systems are operating

Embedded Systems Design Scott DeCota Modern Operating Systems Embedded systems are all around us. They run the engine, brakes, seatbelt, airbag, and audio system in your car. They digitally encode your voice and construct a radio signal to send it from your cell phone to a base station. They control your microwave, dishwasher, and DVD player. They command robots on a factory floor, power generation in a plant, processes in a chemical plant, and the traffic lights in the city. Embedded operating

are processed in order and executed by the central processing unit (CPU). The focal point is the CPU, which contains an arithmetic login unit (ALU), control unit (CU), and registers (small storage areas). The ALU performs mathematical functions, especially addition. The CU controls the data traffic in and out of the CPU. The registers are small high-speed units that store instructions and data for the CPU. The CPU accepts input and provides output to external devices. A crystal clock, known as the

pre-setout goals.1 IS consists of four components which are the input, proccessing, output which all work together to form feeback information which is accurate and useful. The ‘‘Input component’’ is when the system collects and stores raw, unrefined data so that the data can then be processed and made into more useful and specific data, known as the ‘processing component’.2 The ‘‘processing component’’ takes all the data captured in the input step
