indicate the function of each. Central Processing Unit (CPU)- is where the actual computing takes place which includes three major subcomponents: arithmetic/logic unit (ALU), control unit and registers. The speed and power of the CPU influences the computers capabilities. Primary Storage- is the internal memory where data is stored for access by the CPU Secondary Storage- consists of devices and media designed to maintain small or large quantities of data. Input Devices- is a way of entering data

A system is a set of interacting or interdependent components forming an integrated whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning. Fields that study the general properties of systems include systems science, systems theory, systems modeling, systems engineering, cybernetics, dynamical systems, thermodynamics, complex systems, system analysis and design and systems

company's own management and directors. Today more and more companies are moving from the manual accounting systems to computerized accounting information systems. The advantages of a computerized system are increases in the speed and accuracy of processing accounting information. However, as systems become computerized, the internal controls for that system has to be adapted accordingly. This is because computerized systems bring with them certain unique problems that can only be removed or minimized

“compute” which means to calculate and it is a device that can perform arithmetic operations and take logical decisions. Computer is an electronic device; used to convert Data into Information, it takes input (data) through input devices process it into CPU, stores it and also displays the result through output devices. A computer is a programmable machine. The two principal characteristics of a computer are; it responds to a specific set of instructions in a well-defined manner and it can execute a prerecorded

SOFTWARE REQUIREMENTS SPECIFICATION RFID Parking Garage Anthony Nichols Matthew Nichols 1.0 Introduction Finding parking spaces for automobiles and motorcycles can a problematic venture due to limited space and time, while the selling of parking spaces is potential lucrative endeavor. Currently, most large parking garages, including airport parking, use a ticketing system in which users get a time-stamped ticket when entering the structure and pay a time relative fee when exiting. The transmission

"small" signal the output is a replica of the input except for a change in amplitude. In simple terms this means that a sine wave in gives you a sine wave out. That is the hallmark of a linear system. Large Signal Amplifier A large signal will however make the device operate in a non-linear fashion by clipping the output or introducing various kinds of distortion. This is why you cannot turn the volume on an amplifier all the way up to the maximum value because even small input signals will be reduced

procedures. That is, through detective controls, corrective control procedures should be developed to identify the cause of an organization’s problem, correct any difficulties or errors resulting from the problem, and modify the organization’s processing system so that future occurrences of the problem will hopefully be eliminated or at least minimized. b)From the standpoint of evaluating a company’s internal control system, a performance report is a type of report that provides information to
