...Computer A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format. A computer can process data, pictures, sound and graphics. They can solve highly complicated problems quickly and accurately. Block Diagram Input Unit: Computers need to receive data and instruction in order to solve any problem. Therefore we need to input the data and instructions into the computers. The input unit consists of one or more input devices. Keyboard is the one of the most commonly used input device. Other commonly used input devices are the mouse, floppy disk drive, magnetic tape, etc. All the input devices perform the following functions. Accept the data and instructions from the outside world. Convert it to a form that the computer can understand. Supply the converted data to the computer system for further processing. Storage Unit: The storage unit of the computer holds data and instructions that are entered through the input unit, before they are processed. It preserves the intermediate and final results before these are sent to the output devices. It also saves the data for the later use. Memory Size: All digital computers use the binary system, i.e. 0’s and 1’s. Each character or a number is represented by an 8 bit code. The set of 8 bits is called a byte. A character occupies 1 byte space. A numeric occupies 2 byte space. Byte is the space occupied in the memory. The size of the primary storage...

Moore’s Law: Actual Meaning – April 1965 Gordon made an observation that approximately every 18-24 months twice as many semiconductors can be stored on a chip/ double storage capacity (NOT a LAW) 2. Moore’s Law: Generalized meanings – the speed of computers is set to double every two years 3. Central Processing Unit (CPU) and the three primary components thereof – the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control & input/output (I/O) operations specified by the instructions.

Main Memory- (aka RAM/ physical storage) constructed from integrated circuits and needs to have electrical power in order to maintain its formation. When power is lost, so is the information. Made up electronic circuits > 2 state situation ON/OFF, High voltage/ low voltage, negatively charged/ positively charged. *PHYSICAL – reality *LOGICAL – a model; not the truth 2. Control Unit- extracts instructions from memory and decodes and executes them calling on the ALU when necessary 3. Arithmetic logic unit (ALU) - performs arithmetic and logical operations 4.

...Data Mining with R: learning by case studies Luis Torgo LIACC-FEP, University of Porto R. Campo Alegre, 823 - 4150 Porto, Portugal email: ltorgo@liacc.up.pt http://www.liacc.up.pt/∼ltorgo May 22, 2003 Preface The main goal of this book is to introduce the reader to the use of R as a tool for performing data mining. R is a freely downloadable1 language and environment for statistical computing and graphics. Its capabilities and the large set of available packages make this tool an excellent alternative to the existing (and expensive!) data mining tools. One of the key issues in data mining is size. A typical data mining problem involves a large database from where one seeks to extract useful knowledge. In this book we will use MySQL as the core database management system. MySQL is also freely available2 for several computer platforms. This means that you will be able to perform “serious” data mining without having to pay any money at all. Moreover, we hope to show you that this comes with no compromise in the quality of the obtained solutions. Expensive tools do not necessarily mean better tools! R together with MySQL form a pair very hard to beat as long as you are willing to spend some time learning how to use them. We think that it is worthwhile, and we hope that you are convinced as well at the end of reading this book. The goal of this book is not to describe all facets of data mining processes. Many books exist that cover this area. Instead we propose to introduce...
